SUMMARY OF SIGNIFICANT ACCOUNTI

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES	6 Months Ended

Organization, Consolidation and Presentation of Financial Statements [Abstract]
SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES	SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES Principles of Consolidation The condensed consolidated financial statements include the accounts of Barnwell Industries, Inc. and all majority-owned subsidiaries (collectively referred to herein as “Barnwell,” “we,” “our,” “us,” or the “Company”), including a 77.6% -owned land investment general partnership (Kaupulehu Developments) and a 75% -owned land investment partnership (KD Kona 2013 LLLP). All significant intercompany accounts and transactions have been eliminated. Undivided interests in oil and natural gas exploration and production joint ventures are consolidated on a proportionate basis. Barnwell’s investments in both unconsolidated entities in which a significant, but less than controlling, interest is held and in variable interest entities in which the Company is not deemed to be the primary beneficiary are accounted for by the equity method. Unless otherwise indicated, all references to “dollars” in this Form 10-Q are to U.S. dollars. Unaudited Interim Financial Information The accompanying unaudited condensed consolidated financial statements and notes have been prepared by Barnwell in accordance with the rules and regulations of the United States (“U.S.”) SEC. Accordingly, certain information and footnote disclosures normally included in the annual financial statements prepared in accordance with U.S. generally accepted accounting principles (“GAAP”) have been condensed or omitted pursuant to those rules and regulations, although the Company believes that the disclosures made are adequate to make the information not misleading. These condensed consolidated financial statements and notes should be read in conjunction with the consolidated financial statements and notes thereto included in Barnwell’s September 30, 2019 Annual Report on Form 10-K, as amended by our Form 10-K/A Amendment No. 1 and Form 10-K/A Amendment No. 2. The Condensed Consolidated Balance Sheet as of September 30, 2019 has been derived from audited consolidated financial statements. In the opinion of management, all adjustments (which include only normal recurring adjustments) necessary to present fairly the financial position at March 31, 2020 , results of operations and comprehensive (loss) income for the three and six months ended March 31, 2020 and 2019 , and equity and cash flows for the six months ended March 31, 2020 and 2019 , have been made. The results of operations for the period ended March 31, 2020 are not necessarily indicative of the operating results for the full year. Use of Estimates in the Preparation of Condensed Consolidated Financial Statements The preparation of the condensed consolidated financial statements in conformity with U.S. GAAP requires management of Barnwell to make estimates and assumptions that affect the reported amounts of assets, liabilities, revenues and expenses and the disclosure of contingent assets and liabilities. Actual results could differ significantly from those estimates. Significant assumptions are required in the valuation of deferred tax assets, asset retirement obligations, share-based payment arrangements, obligations for retirement plans, contract drilling estimated costs to complete, proved oil and natural gas reserves, and the carrying value of other assets, and such assumptions may impact the amount at which such items are recorded. Significant Accounting Policies Other than the accounting policies implemented in connection with the adoption of Accounting Standards Update (“ASU”) No. 2016-02, “Leases (Topic 842)” discussed in Note 12, there have been no changes to Barnwell's significant accounting policies as described in the Notes to Consolidated Financial Statements included in Item 8 of the Company's most recently filed Annual Report on Form 10-K, as amended by our Form 10-K/A Amendment No. 1 and Form 10-K/A Amendment No. 2. Recently Adopted Accounting Pronouncements In February 2016, the Financial Accounting Standards Board (“FASB”) issued ASU No. 2016-02, “Leases (Topic 842),” which requires an entity to recognize a right-of-use asset and a lease liability on the balance sheet for all leases with terms greater than 12 months at the lease commencement date. The Company adopted the provisions of this ASU effective October 1, 2019. See Note 12 “Leases and Gain on Sale of Asset.” In February 2018, the FASB issued ASU No. 2018-02, “Reclassification of Certain Tax Effects From Accumulated Other Comprehensive Income,” which allows a reclassification from accumulated other comprehensive income to retained earnings for stranded tax effects resulting from the Tax Cuts and Jobs Act of 2017. The Company adopted the provisions of this ASU effective October 1, 2019. The adoption of this update did not have an impact on Barnwell's consolidated financial statements. In July 2018, the FASB issued ASU No. 2018-09, “Codification Improvements,” which provides further clarification to the codification literature. The Company adopted the provisions of this ASU effective October 1, 2019. The adoption of this update did not have an impact on Barnwell's consolidated financial statements. Impact of COVID-19 On March 11, 2020, the World Health Organization declared the COVID-19 outbreak a global pandemic and the United States and Canadian governments declared the virus a national emergency shortly thereafter. As a result, the normal operations of many businesses have been disrupted, including the temporary closure or scale-back of business operations and/or the imposition of either quarantine or remote work or meeting requirements for employees, either by government order or on a voluntary basis. The global economy, our markets and our business have already been materially and adversely affected by COVID-19. In the quarter ended March 31, 2020, the COVID-19 outbreak caused significant reductions in demand for oil and oil prices, which has caused the Company to suspend the development of proved undeveloped reserves and has impacted the Company’s financial condition and outlook. Additionally, demand for real estate in the area where the Company’s land investment segment holds interests has declined as evidenced by no developer lot sales in the recent period. While the Company’s contract drilling segment continues to work as allowed under applicable government exemptions for such work, the impact of COVID-19 on the ability or desire for customers to continue such work is uncertain, and any discontinuation of contracts currently in backlog would result in a material adverse impact to the Company’s financial condition and outlook. Both the health and economic aspects of the COVID-19 pandemic are highly fluid and the future course of each is uncertain. We cannot foresee whether the outbreak of COVID-19 will be effectively contained on a sustained basis, nor can we predict the severity and duration of its impact. If the outbreak of COVID-19 is not effectively and timely controlled, our business operations and financial condition may continue to be materially and adversely affected as a result of the deteriorating market outlook, the global economic recession, weakened liquidity or factors that we cannot foresee. Any of these factors and other factors beyond our control could have an adverse effect on the overall business environment, cause uncertainties in the regions where we conduct business, cause our business to suffer in ways that we cannot predict and materially and adversely impact our business, financial condition and results of operations.

GOING CONCERN

GOING CONCERN	6 Months Ended

Organization, Consolidation and Presentation of Financial Statements [Abstract]
GOING CONCERN	GOING CONCERN The accompanying condensed consolidated financial statements have been prepared on a going concern basis, which contemplates the realization of assets and satisfaction of liabilities in the normal course of business for the twelve-month period following the date of issuance of these condensed consolidated financial statements. Our ability to sustain our business in the future will depend on sufficient oil and natural gas operating cash flows, which are highly sensitive to potentially volatile oil and natural gas prices, sufficient contract drilling operating cash flows, which are subject to potentially large changes in demand, and sufficient future land investment segment proceeds and distributions from the Kukio Resort Land Development Partnerships, the timing of which are both highly uncertain and not within Barnwell’s control. A sufficient level of such cash inflows are necessary to fund discretionary oil and natural gas capital expenditures, which must be economically successful to provide sufficient returns, as well as fund our non-discretionary outflows such as oil and natural gas asset retirement obligations and ongoing operating and general and administrative expenses. We have experienced a trend of losses and negative operating cash flows in recent years. Due to the additional impacts of the COVID-19 pandemic, we now face a greater uncertainty about our cash inflows as described above, which in turn leads to substantial doubt regarding our ability to make the required discretionary cash outflows for the capital expenditures necessary to convert our proved undeveloped reserves to proved developed reserves. Furthermore, because of the greater uncertainty about our cash inflows described above, there is substantial doubt about our ability to fund our non-discretionary cash outflows and thus substantial doubt about our ability to continue as a going concern for one year from the date of the filing of this report. The Company is investigating potential sources of funding, including non-core oil and natural gas property sales, however, no probable sources of such funding have yet been secured. Alternatively, management has the ability to sell its corporate office on the 29th floor of a commercial office building in downtown Honolulu, Hawaii, to generate liquidity without impacting operations significantly, in order to mitigate the substantial doubt about our ability to continue as a going concern. However, the Company’s ability to sell its corporate office at an appropriate time or for a sufficient price is outside of the Company's control and is therefore not probable. Because of this uncertainty as well as uncertainties regarding the potential duration and depth of the impacts of the COVID-19 pandemic on our business as described above, substantial doubt about our ability to continue as a going concern for one year from the date of the filing of this report exists. These financial statements do not include any adjustments that might result from the outcome of these uncertainties.

LOSS PER COMMON SHARE

LOSS PER COMMON SHARE	6 Months Ended
	Mar. 31, 2020
Earnings Per Share [Abstract]
LOSS PER COMMON SHARE	LOSS PER COMMON SHARE Basic loss per share is computed using the weighted-average number of common shares outstanding for the period. Diluted loss per share is calculated using the treasury stock method to reflect the assumed issuance of common shares for all potentially dilutive securities, which consist of outstanding stock options. Potentially dilutive shares are excluded from the computation of diluted loss per share if their effect is anti-dilutive. Options to purchase 60,000 and 318,750 shares of common stock were excluded from the computation of diluted shares for the three and six months ended March 31, 2020 and 2019 , as their inclusion would have been anti-dilutive. Reconciliations between net loss attributable to Barnwell stockholders and common shares outstanding of the basic and diluted net loss per share computations are detailed in the following tables: Three months ended March 31, 2020 Net Loss Shares (Denominator) Per-Share Amount Basic net loss per share $ (1,514,000 ) 8,277,160 $ (0.18 ) Effect of dilutive securities - common stock options — — Diluted net loss per share $ (1,514,000 ) 8,277,160 $ (0.18 ) Six months ended March 31, 2020 Net Loss Shares Per-Share Basic net loss per share $ (1,928,000 ) 8,277,160 $ (0.23 ) Effect of dilutive securities - common stock options — — Diluted net loss per share $ (1,928,000 ) 8,277,160 $ (0.23 ) Three months ended March 31, 2019 Net Loss Shares (Denominator) Per-Share Amount Basic net loss per share $ (2,125,000 ) 8,277,160 $ (0.26 ) Effect of dilutive securities - common stock options — — Diluted net loss per share $ (2,125,000 ) 8,277,160 $ (0.26 ) Six months ended March 31, 2019 Net Loss Shares (Denominator) Per-Share Amount Basic net loss per share $ (6,725,000 ) 8,277,160 $ (0.81 ) Effect of dilutive securities - common stock options — — Diluted net loss per share $ (6,725,000 ) 8,277,160 $ (0.81 )

Investments, All Other Investments [Abstract]
INVESTMENTS	INVESTMENTS A summary of Barnwell’s non-current investments is as follows: March 31, September 30, Investment in Kukio Resort Land Development Partnerships $ 862,000 $ 930,000 Investment in leasehold land interest – Lot 4C 50,000 50,000 Total non-current investments $ 912,000 $ 980,000 Investment in Kukio Resort Land Development Partnerships On November 27, 2013, Barnwell, through a wholly-owned subsidiary, entered into two limited liability limited partnerships, KD Kona 2013 LLLP and KKM Makai, LLLP (“KKM”), and indirectly acquired a 19.6% non-controlling ownership interest in each of KD Kukio Resorts, LLLP, KD Maniniowali, LLLP and KD Kaupulehu, LLLP (“KDK”) for $5,140,000 . These entities, collectively referred to hereinafter as the “Kukio Resort Land Development Partnerships,” own certain real estate and development rights interests in the Kukio, Maniniowali and Kaupulehu portions of Kukio Resort, a private residential community on the Kona coast of the island of Hawaii, as well as Kukio Resort’s real estate sales office operations. KDK holds interests in KD Acquisition, LLLP (“KD I”) and KD Acquisition II, LP, formerly KD Acquisition II, LLLP (“KD II”). KD I is the developer of Kaupulehu Lot 4A Increment I (“Increment I”), and KD II is the developer of Kaupulehu Lot 4A Increment II (“Increment II”). Barnwell’s ownership interests in the Kukio Resort Land Development Partnerships is accounted for using the equity method of accounting. The partnerships derive income from the sale of residential parcels, of which 19 lots remain to be sold at Increment I as of March 31, 2020 , as well as from commissions on real estate sales by the real estate sales office. In March 2019, KD II admitted a new development partner, Replay Kaupulehu Development, LLC (“Replay”), a party unrelated to Barnwell, in an effort to move forward with development of the remainder of Increment II at Kaupulehu. Effective March 7, 2019, KDK and Replay hold ownership interests of 55% and 45% , respectively, of KD II. Accordingly, Barnwell has a 10.8% indirect non-controlling ownership interest in KD II through KDK as of that date that will continue to be accounted for using the equity method of accounting. Barnwell continues to have an indirect 19.6% non-controlling ownership interest in KD Kukio Resorts, LLLP, KD Maniniowali, LLLP, and KD I. There were no cash distributions from the Kukio Resort Land Development Partnerships for the six months ended March 31, 2020 . During the six months ended March 31, 2019, Barnwell received net cash distributions in the amount of $314,000 from the Kukio Resort Land Development Partnerships after distributing $38,000 to non-controlling interests. Barnwell has the right to receive distributions from its non-controlling interest in KKM in proportion to its partner capital sharing ratio of 34.45% . Barnwell is entitled to a 100% preferred return up to $1,000,000 from KKM on any allocated equity in income of the Kukio Resort Land Development Partnerships for cumulative distributions to all of its partners in excess of $45,000,000 from those partnerships. Cumulative distributions from the Kukio Resort Land Development Partnerships have reached the $45,000,000 threshold. However, because we have no control over the distributions from the Kukio Resort Land Development Partnerships and the ability of the Kukio Resort Land Development Partnerships to make such distributions is dependent upon their future sales of lots, we have not recorded any estimated potential preferred return from KKM in our equity in income to date. However, if sufficient distributions are made by the Kukio Resort Land Development Partnerships in the future, Barnwell will have equity in income of affiliates for the recognition of the preferred return. There is no assurance that any future distributions and resulting preferred returns will occur. Equity in loss of affiliates was $25,000 and $68,000 for the three and six months ended March 31, 2020 , respectively, and $207,000 and $286,000 for the three and six months ended March 31, 2019 , respectively. The equity in the underlying net assets of the Kukio Resort Land Development Partnerships exceeds the carrying value of the investment in affiliates by approximately $292,000 as of March 31, 2020 , which is attributable to differences in the value of capitalized development costs and a note receivable. The basis difference will be recognized as the partnerships sell lots and recognize the associated costs and sell memberships for the Kuki`o Golf and Beach Club for which the receivable relates. The basis difference adjustments of $5,000 for the six months ended March 31, 2020 and $1,000 for the six months ended March 31, 2019 increased equity in income of affiliates. Summarized financial information for the Kukio Resort Land Development Partnerships is as follows: Three months ended March 31, 2020 2019 Revenue $ 1,224,000 $ 371,000 Gross profit $ 651,000 $ 205,000 Net loss $ (135,000 ) $ (904,000 ) Six months ended March 31, 2020 2019 Revenue $ 2,990,000 $ 2,319,000 Gross profit $ 1,447,000 $ 851,000 Net loss $ (303,000 ) $ (1,062,000 ) Sale of Interest in Leasehold Land Kaupulehu Developments has the right to receive payments from KD I and KD II resulting from the sale of lots and/or residential units within Increment I and Increment II by KD I and KD II (see Note 15). With respect to Increment I, Kaupulehu Developments is entitled to receive payments from KD I based on the following percentages of the gross receipts from KD I’s sales of single-family residential lots in Increment I: 10% of such aggregate gross proceeds greater than $100,000,000 up to $300,000,000 ; and 14% of such aggregate gross proceeds in excess of $300,000,000 . The total amount of gross proceeds from single-family lots sales was $216,400,000 through March 31, 2020 . No single-family lots were sold during the six months ended March 31, 2020 and 19 single-family lots, of the 80 lots developed within Increment I, remained to be sold as of March 31, 2020 . Under the terms of the former Increment II agreement with KD II, Kaupulehu Developments was entitled to receive payments from KD II resulting from the sale of lots and/or residential units by KD II within Increment II. Through March 6, 2019, the payments were based on a percentage of gross receipts from KD II's sales ranging from 8% to 10% of the price of improved or unimproved lots or 2.60% to 3.25% of the price of units constructed on a lot, to be determined in the future depending upon a number of variables, including whether the lots are sold prior to improvement. Two ocean front parcels approximately two to three acres in size fronting the ocean were developed within Increment II by KD II, of which one was sold in fiscal 2017 and one was sold in fiscal 2016. The remaining acreage within Increment II is not yet under development. Through March 6, 2019, Kaupulehu Developments was also entitled to receive 50% of distributions otherwise payable from KD II to its members after the members of KD II have received distributions equal to the original basis of capital invested in the project, up to $8,000,000 . Through March 6, 2019, a cumulative total of $3,500,000 was received from KD II under this arrangement, out of the $8,000,000 maximum. The former arrangement also included the rights to three single-family residential lots in Phase 2 of Increment II when developed, at no cost to Barnwell, with a commitment by Barnwell to begin to construct a residence upon each lot within six months of transfer. Concurrent with the transaction whereby KD II admitted Replay as a new development partner, Kaupulehu Developments entered into new agreements with KD II whereby the aforementioned terms of the former Increment II arrangement were eliminated and Kaupulehu Developments will instead be entitled to 15% of the distributions of KD II, the cost of which is to be solely borne by KDK out of its 55% ownership interest in KD II, plus a priority payout of 10% of KDK’s cumulative net profits derived from Increment II sales subsequent to Phase 2A, up to a maximum of $3,000,000 as to the priority payout. Such interests are limited to distributions or net profits interests and Barnwell will not have any partnership interests in KD II or KDK through its interest in Kaupulehu Developments. The new arrangement also gives Barnwell rights to three single-family residential lots in Phase 2A of Increment II, and four single-family residential lots in phases subsequent to Phase 2A when such lots are developed by KD II, all at no cost to Barnwell. Barnwell is committed to commence construction of improvements within 90 days of the transfer of the four lots in the phases subsequent to Phase 2A as a condition of the transfer of such lots. Also, in addition to Barnwell’s existing obligations to pay professional fees to certain parties based on percentages of its gross receipts, Kaupulehu Developments is now also obligated to pay an amount equal to 0.72% and 0.2% of the cumulative net profits of KD II to KD Development, LLC and a pool of various individuals, respectively, all of whom are partners of KKM and are unrelated to Barnwell, in compensation for the agreement of these parties to admit the new development partner for Increment II. Such compensation will be reflected as the obligation becomes probable and the amount of the obligation can be reasonably estimated. The new agreements also specify that Kaupulehu Developments was to be paid $1,000,000 by KD II prior to admission of Replay as a partner. This $1,000,000 payment had already been received in June 2018 and is included in the $3,500,000 cumulative total as of March 6, 2019 discussed above. The Increment I percentage of sales arrangement between Barnwell and KD I remains unchanged. The following table summarizes the Increment I and Increment II revenues from KD I and KD II and the amount of fees directly related to such revenues: Three months ended Six months ended 2020 2019 2020 2019 Sale of interest in leasehold land: Revenues - sale of interest in leasehold land $ — $ — $ — $ 165,000 Fees - included in general and administrative expenses — — — (20,000 ) Sale of interest in leasehold land, net of fees paid $ — $ — $ — $ 145,000 Investment in Leasehold Land Interest - Lot 4C Kaupulehu Developments holds an interest in an area of approximately 1,000 acres of vacant leasehold land zoned conservation located adjacent to Lot 4A, which currently has no development potential without both a development agreement with the lessor and zoning reclassification. The lease terminates in December 2025.

OIL AND NATURAL GAS PROPERTIES

OIL AND NATURAL GAS PROPERTIES	6 Months Ended

Oil and Natural Gas Properties [Abstract]
OIL AND NATURAL GAS PROPERTIES	OIL AND NATURAL GAS PROPERTIES Dispositions In October 2019, Barnwell entered into a purchase and sale agreement with an independent third party and sold its interests in properties located in the Progress area of Alberta, Canada. The sales price per the agreement was adjusted for customary purchase price adjustments to $594,000 in order to, among other things, reflect an economic effective date of October 1, 2019. The final determination of the customary adjustments to the purchase price has not yet been made however it is not expected to result in a material adjustment. The proceeds were credited to the full cost pool, with no gain or loss recognized, as the sale did not result in a significant alteration of the relationship between capitalized costs and proved reserves. There were no oil and natural gas property dispositions during the six months ended March 31, 2019. The $1,519,000 of proceeds from sale of oil and natural gas properties included in the Condensed Consolidated Statement of Cash Flows for the six months ended March 31, 2019 primarily represents the refund of income taxes previously withheld from what otherwise would have been proceeds on the previous years' oil and natural gas property sales. Acquisitions There were no significant amounts paid for oil and natural gas property acquisitions during the six months ended March 31, 2020 . In the quarter ended December 31, 2018, Barnwell acquired additional working interests in oil and natural gas properties located in the Wood River and Twining areas of Alberta, Canada for cash consideration of $355,000 . The purchase prices per the agreements were adjusted for customary purchase price adjustments to reflect the economic activity from the effective date to the closing date. The customary adjustments to the purchase prices were finalized during the quarter ended June 30, 2019 and resulted in an immaterial adjustment. There were no oil and natural gas property acquisitions during the quarter ended March 31, 2019. Impairment of Oil and Natural Gas Properties Under the full cost method of accounting, the Company performs quarterly oil and natural gas ceiling test calculations. Changes in the mandated 12-month historical rolling average first-day-of-the-month prices for oil, natural gas and natural gas liquids prices, the value of reserve additions as compared to the amount of capital expenditures to obtain them, and changes in production rates and estimated levels of reserves, future development costs and the estimated market value of unproved properties, impact the determination of the maximum carrying value of oil and natural gas properties. Prior to the three months ended March 31, 2020, the ceiling test calculation included management’s estimation that the Company had the ability to fund the approximately $12,000,000 of future capital expenditures necessary over the next five years to develop proved undeveloped reserves in the Twining area of Alberta, Canada. However, due to the impact on oil prices and the extreme uncertainties created by the COVID-19 pandemic during the three months ended March 31, 2020 on the Company's financial outlook, management is no longer reasonably certain that the Company will have the financial resources necessary to make any of the approximately $12,000,000 of capital expenditures necessary to develop the proved undeveloped reserves. Therefore, the proved undeveloped reserves have been excluded from the ceiling test calculation and the Company incurred a $1,637,000 ceiling test impairment in the three and six months ended March 31, 2020. As discussed above, the ceiling test mandates the use of the 12-month historical rolling average first-day-of-the-month prices. Given the recent decline in oil prices, current oil prices are now lower than the 12-month historical rolling average first-day-of-the-month oil price used in our ceiling test calculation for the quarter ended March 31, 2020. If oil prices remain at current levels or decline further, it is more likely than not that the Company will incur further impairment write-downs in future periods in the absence of any offsetting factors that are not currently known or projected, as the 12-month historical rolling average first-day-of-the-month oil prices used in our oil and natural gas ceiling test would continue to decline during each rolling quarterly period in 2020. Based on the oil prices for April 1 and May 1 and the estimated oil price for June 1 of 2020, oil prices are estimated to be approximately 65% lower than April 1, May 1, and June 1 of 2019 oil prices, which will result in an approximately 18% decrease in the 12-month historical rolling first-day-of-the-month average oil price for the quarter ending June 30, 2020. During the three and six months ended March 31, 2019, there was a $243,000 and $2,413,000 ceiling test impairment, respectively.

Retirement Benefits [Abstract]
RETIREMENT PLANS	RETIREMENT PLANS Barnwell sponsors a noncontributory defined benefit pension plan (“Pension Plan”) covering substantially all of its U.S. employees. Additionally, Barnwell sponsors a Supplemental Employee Retirement Plan (“SERP”), a noncontributory supplemental retirement benefit plan which covers certain current and former employees of Barnwell for amounts exceeding the limits allowed under the Pension Plan, and a postretirement medical insurance benefits plan (“Postretirement Medical”) covering eligible U.S. employees. The following tables detail the components of net periodic benefit (income) cost for Barnwell’s retirement plans: Pension Plan SERP Postretirement Medical Three months ended March 31, 2020 2019 2020 2019 2020 2019 Service cost $ — $ 50,000 $ — $ 9,000 $ — $ — Interest cost 72,000 94,000 15,000 21,000 20,000 25,000 Expected return on plan assets (172,000 ) (160,000 ) — — — — Amortization of prior service cost (credit) — 2,000 — (1,000 ) — — Amortization of net actuarial loss — 1,000 — 1,000 20,000 13,000 Net periodic benefit (income) cost $ (100,000 ) $ (13,000 ) $ 15,000 $ 30,000 $ 40,000 $ 38,000 Pension Plan SERP Postretirement Medical Six months ended March 31, 2020 2019 2020 2019 2020 2019 Service cost $ 50,000 $ 100,000 $ 3,000 $ 18,000 $ — $ — Interest cost 155,000 187,000 33,000 42,000 40,000 50,000 Expected return on plan assets (335,000 ) (321,000 ) — — — — Amortization of prior service cost (credit) 1,000 3,000 (1,000 ) (2,000 ) — — Amortization of net actuarial loss 35,000 4,000 5,000 2,000 40,000 26,000 Curtailment cost (income) 53,000 — (53,000 ) — — — Net periodic benefit (income) cost $ (41,000 ) $ (27,000 ) $ (13,000 ) $ 60,000 $ 80,000 $ 76,000 The net periodic benefit (income) cost, including service cost, is included in “General and administrative” expenses in the Company's Condensed Consolidated Statements of Operations. On December 12, 2019, the Company’s Board of Directors approved a resolution to freeze all future benefit accruals for all participants under the Company’s Pension Plan and SERP effective December 31, 2019. Accordingly, the Company remeasured the projected benefit obligation of the Pension Plan and SERP as of December 31, 2019. As a result of the remeasurement, the Company recorded an $880,000 actuarial gain in accumulated other comprehensive loss during the quarter ended December 31, 2019. The actuarial gain was primarily due to an increase in the market value of Pension Plan assets as well as an increase in the discount rate for both plans during the period. The impact of the Pension Plan and SERP plan freeze resulted in a $1,699,000 reduction in unrecognized pension benefit costs that were previously included in accumulated other comprehensive loss, with a corresponding benefit in other comprehensive income which was recorded in the first quarter ended December 31, 2019. No remeasurement was required for the three months ended March 31, 2020. Currently, no contributions are expected to be made to the Pension Plan during fiscal 2020. The SERP and Postretirement Medical plans are unfunded, and Barnwell funds benefits when payments are made. Expected payments under the Postretirement Medical plan and the SERP for fiscal 2020 are not material. Fluctuations in actual equity market returns as well as changes in general interest rates will result in changes in the market value of plan assets and may result in increased or decreased retirement benefits costs and contributions in future periods.

Income from our non-controlling interest in the Kukio Resort Land Development Partnerships is treated as non-unitary for state of Hawaii unitary filing purposes, thus unitary Hawaii losses provide limited sheltering of such non-unitary income. On March 27, 2020, the Coronavirus Aid, Relief, and Economic Security (“CARES”) Act was signed into law to provide economic relief to businesses that were negatively impacted by the COVID-19 pandemic. Key tax provisions of the CARES Act currently impacting the Company include the modification of rules related to alternative minimum tax (“AMT”) credits and net operating losses (“NOL”). Other provisions of the CARES Act are currently inapplicable to the Company and/or do not impact the Company’s U.S. federal current and deferred income taxes. Under previous legislation, 50% of the total AMT credit carryover was refundable upon the filing of the Company's U.S. federal income tax return for the year ended September 30, 2019 and was reclassified to current taxes receivable as of September 30, 2019. The CARES Act provides for an election, which the Company has made, to take the entire refundable credit in the Company’s U.S. federal income tax return for the year ended September 30, 2019. As such, the Company reclassified the remaining 50% from non‑current income taxes receivable to current income taxes receivable as of March 31, 2020 as a result of CARES Act. Under previous legislation, the utilization of NOLs generated in tax years beginning after December 31, 2017, which was the Company's fiscal year ended September 30, 2019, was restricted to 80% of taxable income. The CARES Act suspended this restriction through the 2020 tax year (the Company’s fiscal year ending September 30, 2021). This limitation will be reinstated effective for tax years beginning on or after January 1, 2021.

Retainage, included in contract assets, represents amounts due from customers, but where payments are withheld contractually until certain construction milestones are met. Amounts retained typically range from 5% to 10% of the total invoice, up to contractually-specified maximums. The Company classifies as a current asset those retainages that are expected to be collected in the next twelve months. Contract assets represent the Company’s rights to consideration in exchange for services transferred to a customer that have not been billed as of the reporting date. The Company’s rights are generally unconditional at the time its performance obligations are satisfied. When the Company receives consideration, or such consideration is unconditionally due, from a customer prior to transferring goods or services to the customer under the terms of a sales contract, the Company records deferred revenue, which represents a contract liability. Such deferred revenue typically results from billings in excess of costs and estimated earnings on uncompleted contracts. As of March 31, 2020 and September 30, 2019 , the Company had $1,141,000 and $1,633,000 , respectively, included in “Other current liabilities” on the balance sheets for those performance obligations expected to be completed in the next twelve months. During the six months ended March 31, 2020 and 2019 , the amount of revenue recognized that was previously included in contract liabilities as of the beginning of the respective period was $707,000 and $22,000 , respectively. Contracts are sometimes modified for a change in scope or other requirements. The Company considers contract modifications to exist when the modification either creates new or changes the existing enforceable rights and obligations. Most of the Company’s contract modifications are for goods and services that are not distinct from the existing performance obligations. The effect of a contract modification on the transaction price, and the measure of progress for the performance obligation to which it relates, is recognized as an adjustment to revenue (either as an increase or decrease) on a cumulative catchup basis. Performance Obligations The Company’s remaining performance obligations for drilling and pump installation contracts (hereafter referred to as “backlog”) represent the unrecognized revenue value of the Company’s contract commitments. The Company’s backlog may vary significantly each reporting period based on the timing of major new contract commitments. In addition, our customers have the right, under some infrequent circumstances, to terminate contracts or defer the timing of the Company’s services and their payments to us. Nearly all of the Company's contract drilling segment contracts have original expected durations of one year or less. At March 31, 2020 , the Company had three contract drilling jobs with original expected durations of greater than one year. For these contracts, approximately 89% of the remaining performance obligation of $2,458,000 is expected to be recognized in the next twelve months and the remaining, thereafter. At September 30, 2019 , the Company had three contract drilling jobs with original durations of greater than one year. For those contracts, approximately 79% of the remaining performance obligation of $2,866,000 was expected to be recognized as revenue in the next twelve months and the remaining, thereafter. Contract Fulfillment Costs Preconstruction costs, which include costs such as set-up and mobilization, are capitalized and allocated across all performance obligations and deferred and amortized over the contract term on a progress towards completion basis. As of March 31, 2020 and September 30, 2019 , the Company had $199,000 and $296,000 , respectively, in unamortized preconstruction costs related to contracts that were not completed. During the three and six months ended March 31, 2020 and 2019, the amortization of preconstruction costs related to contracts were not material and were included in the accompanying Condensed Consolidated Statements of Operations. Additionally, no impairment charges in connection with the Company’s preconstruction costs were recorded during the three and six months ended March 31, 2020 and 2019 . Water Well Re-drill In the quarter ended December 31, 2019, the Company experienced the failure of a hole opener which broke apart leaving pieces in the bottom of a water well being drilled in Hawaii. Efforts to remove the items from the well were unsuccessful through the three months ended March 31, 2020 and subsequently, the Company determined that the well should be abandoned and a new well drilled at no incremental cost to the customer as per the terms of the contract. Accordingly, all the costs to drill and abandon the first well, which are all wasted costs, have been excluded from the measurement of progress toward contract completion and all such costs were fully accrued as of March 31, 2020, as this contract was determined to be a loss job. As a result, $979,000 and $733,000 of revenue previously recognized was reversed in the three and six months ended March 31, 2020, respectively, and the Company recognized a decrease of approximately $750,000 in the estimated margin of this contract in the three and six months ended March 31, 2020.

Fair Value Disclosures [Abstract]
FAIR VALUE MEASUREMENTS	FAIR VALUE MEASUREMENTS The carrying values of cash and cash equivalents, accounts and other receivables, accounts payable and accrued current liabilities approximate their fair values due to the short-term nature of the instruments. Assets and Liabilities Measured at Fair Value on a Nonrecurring Basis The estimated fair values of oil and natural gas properties and the asset retirement obligation incurred in the drilling of oil and natural gas wells or assumed in the acquisitions of additional oil and natural gas working interests are based on an estimated discounted cash flow model and market assumptions. The significant Level 3 assumptions used in the calculation of estimated discounted cash flows included future commodity prices, projections of estimated quantities of oil and natural gas reserves, expectations for timing and amount of future development, operating and asset retirement costs, projections of future rates of production, expected recovery rates and risk adjusted discount rates. Barnwell estimates the fair value of asset retirement obligations based on the projected discounted future cash outflows required to settle abandonment and restoration liabilities. Such an estimate requires assumptions and judgments regarding the existence of liabilities, the amount and timing of cash outflows required to settle the liability, what constitutes adequate restoration, inflation factors, credit adjusted discount rates, and consideration of changes in legal, regulatory, environmental and political environments. Abandonment and restoration cost estimates are determined in conjunction with Barnwell’s reserve engineers based on historical information regarding costs incurred to abandon and restore similar well sites, information regarding current market conditions and costs, and knowledge of subject well sites and properties. Asset retirement obligation fair value measurements in the current period were Level 3 fair value measurements.

LEASES

Leases [Abstract]
LEASES	LEASES AND GAIN ON SALE OF ASSET On October 1, 2019, the Company adopted ASU No. 2016-02, “Leases (Topic 842),” using the modified retrospective transition approach and applied the new standard to leases in place as of the adoption date. Results for reporting periods prior to October 1, 2019 have not been adjusted. The Company elected the package of practical expedients allowed upon adoption of Accounting Standards Codification (“ASC”) 842 which, among other things, allowed us to (1) not reassess whether any expired or existing contracts contain leases, (2) carry forward the historical lease classification, and (3) not have to reassess any initial direct cost of any expired or existing leases. As a result of the adoption of ASC 842, the Company recorded operating lease right-of-use (“ROU”) assets of $2,589,000 and corresponding total operating lease liabilities of $2,589,000 in the Condensed Consolidated Balance Sheets as of October 1, 2019. There was no impact to retained earnings or the Condensed Consolidated Statements of Operations. In March 2020, the Company sold its leasehold interest in a three-quarter of an acre contract drilling segment maintenance and storage yard in Honolulu, Hawaii to an unrelated third party for a $1,100,000 cash payment. As a result of the sale transaction, the Company recognized a gain of $1,336,000 , inclusive of a $236,000 gain from the reversal of the storage yard's lease liability in excess of the right-of-use asset, in the quarter ended March 31, 2020. The Company’s remaining ROU assets and lease liabilities at March 31, 2020, primarily relate to non-cancelable operating leases for our Canadian office space and our leasehold land interest for Lot 4C held by Kaupulehu Developments. Management determines if a contract is or contains a lease at inception of the contract or modification of the contract. A contract is or contains a lease if the contract conveys the right to control the use of the asset for a period in exchange for consideration. Operating lease ROU assets and liabilities are recognized based on the present value of future minimum lease payments over the expected lease term at commencement date. The Company’s leases do not provide a readily determinable implicit rate; therefore, management uses the Company’s incremental borrowing rate to discount lease payments based on information available at lease commencement. Our lease terms may include options to extend or terminate the lease when it is reasonably certain we will exercise that potion. Lease expense for minimum lease payments is recognized on a straight-line basis over the expected lease terms. The Company has lease agreements with lease and non-lease components and the non-lease components are excluded in the calculation of the ROU asset and lease liability and expensed as incurred. None of the Company’s lease agreements contain material residual value guarantees or material restrictions or covenants. A ROU asset and corresponding lease liability is not recorded for leases with an initial term of 12 months or less (short-term leases) as the Company recognizes lease expense for these leases as incurred over the lease term. Leases recorded on the balance sheet consist of the following: March 31, Assets: Operating lease right-of-use assets $ 292,000 Total right-of-use assets $ 292,000 Liabilities: Current portion of operating lease liabilities $ 102,000 Operating lease liabilities 196,000 Total lease liabilities $ 298,000 The components of lease expenses are as follows: Three months ended Six months ended Operating lease cost $ 101,000 $ 203,000 Short-term lease cost 18,000 35,000 Total lease cost $ 119,000 $ 238,000 Supplemental information related to leases is as follows: March 31, Cash paid for amounts included in the measurement of lease liabilities: Operating cash flows for operating leases $ 128,000 Operating leases: Weighted-average remaining lease term (in years) 3.8 Weighted-average discount rate 5.84% The remaining lease payments for our operating leases as of March 31, 2020 , are as follows: Fiscal year ending: Remainder of 2020 $ 59,000 2021 118,000 2022 59,000 2023 30,000 2024 30,000 Thereafter through 2026 38,000 Total lease payments 334,000 Less: amounts representing interest (36,000 ) Present value of lease liabilities $ 298,000

Loss Contingency [Abstract]
CONTINGENCIES	CONTINGENCIES Legal and Regulatory Matters Barnwell is routinely involved in disputes with third parties that occasionally require litigation. In addition, Barnwell is required to maintain compliance with all current governmental controls and regulations in the ordinary course of business. Barnwell’s management is not aware of any claims or litigation involving Barnwell that are likely to have a material adverse effect on its results of operations, financial position or liquidity. In the year ended September 30, 2019, two of the water wells drilled by the contract drilling segment for one customer were determined to not meet the contract specifications for plumbness. Subsequently, in the quarter ended March 31, 2020, the Company executed a separate five -year warranty agreement with the customer for one of the wells that did not meet plumbness. Under the terms of the agreement, if the lack of plumbness is determined to be the cause of a pump failure within the warranty period, the Company would be obligated to replace the pump at no cost to the customer. If the Company is unable to replace the pump using industry-standard methods, or if there are two or more pump failures attributable to lack of plumbness within the five -year warranty period, the Company would be obligated to drill a new well at no cost to the customer. Negotiations with the customer are currently ongoing for the other well that the customer claims did not meet plumbness despite the fact that the independent consulting engineer for the job concluded that the most recent plumbness test, completed after the well was cased with casing cemented into place as per the contract, showed that the well meets the plumbness specifications of the contract. Management believes the degrees of deviation for both wells are not impactful to the performance of the submersible pumps that will be installed in those wells. Accordingly, no accruals have been recorded as of March 31, 2020 as there is no probable or estimable contingent liability.

RELATED PARTY TRANSACTIONS	RELATED PARTY TRANSACTIONS Kaupulehu Developments is entitled to receive payments from the sales of lots and/or residential units by KD I and KD II. Through March 6, 2019, Kaupulehu Developments was also entitled to receive 50% of distributions otherwise payable from KD II to its members up to $8,000,000 , of which $3,500,000 was received. KD I and KD II are part of the Kukio Resort Land Development Partnerships in which Barnwell holds indirect 19.6% and 10.8% non-controlling ownership interests, respectively, accounted for under the equity method of investment. The percentage of sales payments and percentage of distribution payments are part of transactions which took place in 2004 and 2006 where Kaupulehu Developments sold its leasehold interests in Increment I and Increment II to KD I's and KD II's predecessors in interest, respectively, which was prior to Barnwell’s affiliation with KD I and KD II which commenced on November 27, 2013, the acquisition date of our ownership interest in the Kukio Resort Land Development Partnerships. Changes to the arrangement above, effective March 7, 2019, are discussed in Note 4. There were no payments made to Kaupulehu Developments by KD I or KD II during the six months ended March 31, 2020 . During the six months ended March 31, 2019 , Barnwell received $165,000 in percentage of sales payments from KD I from the sale of one lot within Phase II of Increment I.

Subsequent Events [Abstract]
SUBSEQUENT EVENTS	SUBSEQUENT EVENTS Paycheck Protection Program Loan On April 28, 2020, the Company, as obligor, entered into a promissory note evidencing an unsecured loan in the approximate amount of $147,000 under the Paycheck Protection Program (“PPP”) pursuant to the CARES Act that was signed into law in March 2020. The note matures two years after the date of the loan disbursement and bears interest at a fixed annual rate of 1.00% , with the first six months of principal and interest deferred. Under the terms of the CARES Act and the PPP, the Company can apply for and be granted forgiveness for all or a portion of the loan issued under the PPP and the loan is expected to be forgiven to the extent the proceeds are used in accordance with the PPP to cover payroll, mortgage interest, rent, and utility costs incurred by the Company over the 24-week period following the loan disbursement date. At this time, the Company believes that its use of the loan proceeds will meet the conditions for forgiveness under the PPP. Canada Emergency Wage Subsidy Subsequent to March 31, 2020, the Company’s two subsidiaries with Canadian operations, Barnwell of Canada, Limited, and Octavian Oil, Ltd., qualified for the Canada Emergency Wage Subsidy (“CEWS”). The CEWS is a program that will provide a subsidy of 75% of eligible employee wages up to a maximum of approximately $600 per week for each employee. As of the date of this report, the Company received a total of approximately $60,000 in CEWS subsidies. The CEWS is currently scheduled to run through August 29, 2020. NYSE American Continued Listing Standard On January 13, 2020, the Company received a letter from NYSE American LLC (the “Exchange”) Staff indicating that the Company is not in compliance with certain continued listing standards relating to stockholders equity as set forth in Part 10, Section 1003 of the NYSE American Company Guide (the “Guide”). Based on the Company’s annual report on Form 10-K for the fiscal year ended September 30, 2019, which was filed with the SEC on December 20, 2019, the Company was below compliance with Part 10, Sections 1003(a)(i) and (a)(ii) of the Guide since it reported stockholders’ equity of $1.2 million and net losses in fiscal years ended September 30, 2019, September 30, 2018 and September 30, 2016. In accordance with the Exchange’s policies and procedures, the Company submitted its plan of compliance on February 12, 2020 (the “Plan”) addressing how the Company intends to regain compliance with Part 10, Section 1003 of the Guide. On April 2, 2020, the Exchange notified the Company that it accepted the Company’s Plan and granted the Company an extension for its continued listing until July 13, 2021 (the “Plan Period”). The Company will be subject to periodic review by Exchange Staff during the Plan Period. The Plan was submitted to the Exchange before the start of the COVID-19 pandemic-related low commodity price environment, the oil price war between Saudi Arabia and Russia and other macroeconomic pressures that have impacted our businesses and the U.S. economy in general. The magnitude and duration of these factors have and will adversely affect the Company’s ability to achieve the Plan’s goals and to return to compliance with the Exchange’s listing standards. If the Company does not regain compliance by the end of the Plan Period, or if the Company does not make progress consistent with its Plan, the Exchange may initiate delisting procedures as appropriate. The potential issues discussed above could result in our inability to satisfy the Exchange’s criteria for continued listing of our common stock. If the Exchange delists our common stock, investors may face material adverse consequences, including, but not limited to, a lack of a trading market for our common stock, reduced liquidity, and an inability for us to obtain financing to fund our operations.

Organization, Consolidation and Presentation of Financial Statements [Abstract]
Principles of Consolidation	Principles of Consolidation The condensed consolidated financial statements include the accounts of Barnwell Industries, Inc. and all majority-owned subsidiaries (collectively referred to herein as “Barnwell,” “we,” “our,” “us,” or the “Company”), including a 77.6% -owned land investment general partnership (Kaupulehu Developments) and a 75% -owned land investment partnership (KD Kona 2013 LLLP). All significant intercompany accounts and transactions have been eliminated. Undivided interests in oil and natural gas exploration and production joint ventures are consolidated on a proportionate basis. Barnwell’s investments in both unconsolidated entities in which a significant, but less than controlling, interest is held and in variable interest entities in which the Company is not deemed to be the primary beneficiary are accounted for by the equity method. Unless otherwise indicated, all references to “dollars” in this Form 10-Q are to U.S. dollars.
Unaudited Interim Financial Information	Unaudited Interim Financial Information The accompanying unaudited condensed consolidated financial statements and notes have been prepared by Barnwell in accordance with the rules and regulations of the United States (“U.S.”) SEC. Accordingly, certain information and footnote disclosures normally included in the annual financial statements prepared in accordance with U.S. generally accepted accounting principles (“GAAP”) have been condensed or omitted pursuant to those rules and regulations, although the Company believes that the disclosures made are adequate to make the information not misleading. These condensed consolidated financial statements and notes should be read in conjunction with the consolidated financial statements and notes thereto included in Barnwell’s September 30, 2019 Annual Report on Form 10-K, as amended by our Form 10-K/A Amendment No. 1 and Form 10-K/A Amendment No. 2. The Condensed Consolidated Balance Sheet as of September 30, 2019 has been derived from audited consolidated financial statements. In the opinion of management, all adjustments (which include only normal recurring adjustments) necessary to present fairly the financial position at March 31, 2020 , results of operations and comprehensive (loss) income for the three and six months ended March 31, 2020 and 2019 , and equity and cash flows for the six months ended March 31, 2020 and 2019 , have been made. The results of operations for the period ended March 31, 2020 are not necessarily indicative of the operating results for the full year.
Use of Estimates in the Preparation of Condensed Consolidated Financial Statements	Use of Estimates in the Preparation of Condensed Consolidated Financial Statements The preparation of the condensed consolidated financial statements in conformity with U.S. GAAP requires management of Barnwell to make estimates and assumptions that affect the reported amounts of assets, liabilities, revenues and expenses and the disclosure of contingent assets and liabilities. Actual results could differ significantly from those estimates. Significant assumptions are required in the valuation of deferred tax assets, asset retirement obligations, share-based payment arrangements, obligations for retirement plans, contract drilling estimated costs to complete, proved oil and natural gas reserves, and the carrying value of other assets, and such assumptions may impact the amount at which such items are recorded.
Recently Adopted Accounting Pronouncements	Recently Adopted Accounting Pronouncements In February 2016, the Financial Accounting Standards Board (“FASB”) issued ASU No. 2016-02, “Leases (Topic 842),” which requires an entity to recognize a right-of-use asset and a lease liability on the balance sheet for all leases with terms greater than 12 months at the lease commencement date. The Company adopted the provisions of this ASU effective October 1, 2019. See Note 12 “Leases and Gain on Sale of Asset.” In February 2018, the FASB issued ASU No. 2018-02, “Reclassification of Certain Tax Effects From Accumulated Other Comprehensive Income,” which allows a reclassification from accumulated other comprehensive income to retained earnings for stranded tax effects resulting from the Tax Cuts and Jobs Act of 2017. The Company adopted the provisions of this ASU effective October 1, 2019. The adoption of this update did not have an impact on Barnwell's consolidated financial statements. In July 2018, the FASB issued ASU No. 2018-09, “Codification Improvements,” which provides further clarification to the codification literature. The Company adopted the provisions of this ASU effective October 1, 2019. The adoption of this update did not have an impact on Barnwell's consolidated financial statements.
Impact of COVID-19	Impact of COVID-19 On March 11, 2020, the World Health Organization declared the COVID-19 outbreak a global pandemic and the United States and Canadian governments declared the virus a national emergency shortly thereafter. As a result, the normal operations of many businesses have been disrupted, including the temporary closure or scale-back of business operations and/or the imposition of either quarantine or remote work or meeting requirements for employees, either by government order or on a voluntary basis. The global economy, our markets and our business have already been materially and adversely affected by COVID-19. In the quarter ended March 31, 2020, the COVID-19 outbreak caused significant reductions in demand for oil and oil prices, which has caused the Company to suspend the development of proved undeveloped reserves and has impacted the Company’s financial condition and outlook. Additionally, demand for real estate in the area where the Company’s land investment segment holds interests has declined as evidenced by no developer lot sales in the recent period. While the Company’s contract drilling segment continues to work as allowed under applicable government exemptions for such work, the impact of COVID-19 on the ability or desire for customers to continue such work is uncertain, and any discontinuation of contracts currently in backlog would result in a material adverse impact to the Company’s financial condition and outlook. Both the health and economic aspects of the COVID-19 pandemic are highly fluid and the future course of each is uncertain. We cannot foresee whether the outbreak of COVID-19 will be effectively contained on a sustained basis, nor can we predict the severity and duration of its impact. If the outbreak of COVID-19 is not effectively and timely controlled, our business operations and financial condition may continue to be materially and adversely affected as a result of the deteriorating market outlook, the global economic recession, weakened liquidity or factors that we cannot foresee. Any of these factors and other factors beyond our control could have an adverse effect on the overall business environment, cause uncertainties in the regions where we conduct business, cause our business to suffer in ways that we cannot predict and materially and adversely impact our business, financial condition and results of operations.
