Description Of Business	'
	1.  DESCRIPTION OF BUSINESS
	Triangle Petroleum Corporation (‘‘we,’’ ‘‘us,’’ ‘‘our,’’ the ‘‘Company,’’ or ‘‘Triangle’’) is a growth-oriented, independent energy holding company with three principal lines of business: oil and natural gas exploration, development and production; oilfield services; and midstream services.
	We hold leasehold interests and conduct our operations in the Williston Basin of North Dakota and Montana.  Our core focus area is in McKenzie and Williams counties, North Dakota (our ‘‘Core Acreage’’).  We conduct our exploration and production operations through our wholly-owned subsidiary, Triangle USA Petroleum Corporation (‘‘TUSA’’).
	In June 2011, we formed RockPile Energy Services, LLC (‘‘RockPile’’), a wholly-owned subsidiary, which provides oilfield and complementary well completion services to oil and natural gas exploration and production companies in the Williston Basin.  RockPile began operations in July 2012.
	In September 2012, through our wholly-owned subsidiary Triangle Caliber Holdings, LLC, we formed Caliber Midstream Partners, L.P. (“Caliber”), an unconsolidated joint venture with First Reserve Energy Infrastructure Fund (“FREIF”).  Caliber was formed for the purpose of providing oil, natural gas and water transportation services to oil and natural gas exploration and production companies in the Williston Basin.
	The Company also holds leasehold interests in acreage in the Maritimes Basin of Nova Scotia.

Basis Of Presentation	'
	2.  BASIS OF PRESENTATION
	These unaudited condensed consolidated financial statements as of April 30, 2014 have been prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”) and are expressed in U.S. dollars.  Preparation in accordance with GAAP requires us to (1) adopt accounting policies within accounting rules set by the Financial Accounting Standards Board (“FASB”) and by the Securities and Exchange Commission (“SEC”), and (2) make estimates and assumptions that affect the reported amounts of assets, liabilities, revenues, expenses and other disclosed amounts.  Note 3 – Summary of Significant Accounting Policies describes our significant accounting policies.
	Certain information and footnote disclosures normally included in our annual financial statements prepared in accordance with GAAP have been condensed or omitted pursuant to SEC rules and regulations.  We believe the disclosures made are adequate to make the information not misleading.  We recommend that these condensed consolidated financial statements be read in conjunction with our audited financial statements and notes included in our Annual Report on Form 10-K for the fiscal year ended January 31, 2014, filed with the SEC on April 17, 2014 (the “Fiscal 2014 Form 10-K”).
	In the opinion of management, the interim data includes all adjustments, consisting only of normal recurring adjustments, necessary for a fair presentation of the results for the interim period.  The results of operations for the three months ended
	April 30, 2014, are not necessarily indicative of the operating results for the entire fiscal year ending January 31, 2015.
	Use of Estimates
	The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities at the date of the financial statements, and the reported amounts of revenues and expenses during the reporting period.  Management believes the major estimates and assumptions impacting our condensed consolidated financial statements are the following:
		·	estimates of proved reserves of oil and natural gas, which affect the calculations of amortization and consideration of any possible impairment of capitalized costs of proved oil and natural gas properties;
		·	estimates of the fair value of unproved oil and natural gas properties we own and the consideration of any possible impairment;
		·	assumptions impacting our estimates as to the future realization of deferred income tax assets and the amount of our deferred tax liabilities;
		·	consideration of any impairment of our other long-term assets;
		·	depreciation of property and equipment; and
		·	valuation of derivative instruments.
	Actual results may differ from estimates and assumptions of future events.  Future production may vary materially from estimated oil and natural gas proved reserves.  Actual future prices may vary significantly from price assumptions used for determining proved reserves and for financial reporting.
	Principles of Consolidation
	The accounts of Triangle and its wholly-owned subsidiaries are presented in the accompanying condensed consolidated financial statements.  All intercompany transactions and balances are eliminated in consolidation.  Triangle generally uses the equity method of accounting for investments in entities in which Triangle has an ownership between 20.0% and 50.0% and exercises significant influence.    Triangle Caliber Holdings, LLC, a wholly-owned subsidiary of Triangle, is a joint venture partner in Caliber.  The Company’s investment in Caliber is accounted for utilizing the equity method of accounting.  See Note 7 - Equity Investment for further discussion.
	Reclassifications
	Certain amounts in the condensed consolidated balance sheet as of January 31, 2014, and in our condensed consolidated statement of operations and comprehensive income for the quarter ended April 30, 2013, have been reclassified to conform to the financial statement presentation for the quarter ended April 30, 2014.  Such reclassifications had no impact on consolidated total assets, stockholders’ equity or net income previously reported.

Summary Of Significant Accounting Policies	'
	3.  SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
	There have been no material changes to the Company’s significant accounting policies and estimates from those disclosed in Note 3 - Summary of Significant Accounting Policies in our audited financial statements included in our Fiscal 2014 Form 10-K.
	New Pronouncements Issued But Not Yet Adopted
	In May 2014, the Financial Accounting Standards Board issued Accounting Standards Update (“ASU”) 2014-09, Revenue from Contracts with Customers, issued as a new Topic, Accounting Standards Codification Topic 606.  The new revenue recognition standard provides a five-step analysis of transactions to determine when and how revenue is recognized.  The core principle of the guidance is that a company should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services.  This ASU is effective for the Company beginning in fiscal year 2017 and can be adopted by the Company either retrospectively or as a cumulative-effect adjustment as of the date of adoption.  We are currently evaluating the effect that adopting this new accounting guidance will have on our consolidated results of operations, cash flows and financial position.
	Accounting standard-setting organizations frequently issue new or revised accounting rules.  We regularly review new pronouncements to determine their impact, if any, on our condensed consolidated financial statements.  Other than the standard discussed above, there are no significant accounting standards applicable to Triangle which have not been adopted.

Segment Reporting [Abstract]	'
Segment Reporting	'
	4.  SEGMENT REPORTING
	We conduct our operations with two reportable operating segments.  We identified each segment based on management’s responsibility and the nature of their products, services, and costs.  There are no major distinctions in geographical areas served as all operations are in the Williston Basin of the United States.  The exploration and production operating segment is responsible for finding and producing oil and natural gas.  The oilfield services segment is responsible for a variety of oilfield and complementary services for both Triangle-operated wells and wells operated by third-parties.
	Management evaluates the performance of our segments based upon net income (loss) before income taxes.  The following tables present selected financial information for our operating segments for the three months ended April 30, 2014 and 2013:

	Eliminations and Other
	For consolidation, intercompany revenues and expenses are eliminated with a corresponding reduction in Triangle's capitalized well costs.
	Under the full cost method, we deferred recognition of an additional $0.6 million and $1.9 million in service income for the three month periods ended April 30, 2014 and 2013, respectively, by charging such service income against service revenue and crediting capitalized costs of the related wells.  The deferred income is indirectly recognized in future periods through a lower amortization rate as proved reserves are produced.

	Acquisitions
	Kodiak Oil & Gas Property Acquisition
	On August 28, 2013, TUSA acquired from Kodiak Oil & Gas Corporation (“Kodiak”) interests in approximately 5,600 net acres of Williston Basin leaseholds, and related producing properties along with various other related rights, permits, contracts, equipment and other assets located in McKenzie County, North Dakota.  We paid approximately $83.8 million in cash, subject to customary post-closing adjustments.  The effective date for the acquisition was July 1, 2013.
	The acquisition is accounted for using the acquisition method under ASC-805, Business Combinations, which requires the assets acquired and liabilities assumed to be recorded at fair value as of the acquisition date of August 28, 2013.  The final purchase price allocation is pending the completion of management’s assessment of the fair value of the assets acquired and liabilities assumed.  Accordingly, the allocation may change as additional information becomes available and is assessed by the Company, and the impact of such changes may be material.
	The following table summarizes the preliminary purchase price and the preliminary estimated values of assets acquired and liabilities assumed:
	(in thousands)
	Preliminary purchase price:
	Consideration given
	Cash			$	83,805
	Total consideration given			$	83,805
	Preliminary fair value allocation of purchase price:

	Proved properties	$	50,200
	Unproved properties		32,976
	Total oil and natural gas properties				83,176
	Accounts payable				761
	Asset retirement obligations assumed				-132
	Fair value of net assets acquired			$	83,805
	Also, on August 2, 2013, the Company closed a trade agreement with Kodiak (the “Trade Agreement”) to exchange certain of Triangle’s oil and natural gas leasehold interests in Kodiak’s operated units in return for approximately 600 net acres of leasehold interests held by Kodiak in units then operated by the Company.  The effective date of the Trade Agreement was also July 1, 2013.
	Pro Forma Financial Information
	The following unaudited pro forma financial information represents the combined results for the Company and the properties acquired and exchanged from Kodiak for the three months ended April 30, 2013, as if the acquisition and exchange had occurred on February 1, 2012.  As Kodiak’s fiscal year is within 93 days of the Company’s fiscal year, no adjustment for the differing periods has been considered.  The following pro forma results include the operating revenues and direct operating expenses for the acquired and exchanged properties for the three months ended April 30, 2013:
		For the Three Months Ended
	(in thousands, except per share data)	30-Apr-13
	Operating revenues	$	40,664
	Net income	$	8,199

	Diluted	$	0.13
	Weighted average common shares outstanding:
	Basic		63,955,152

	The pro forma information includes the effects of adjustments for depreciation, amortization and accretion expense of $3.4 million for the three months ended April 30, 2013.  The pro forma results do not include any cost savings or other synergies that may result from the acquisition or any estimated costs that have been or will be incurred by the Company to integrate the properties acquired.  For purposes of pro forma earnings per common share, it was assumed that the net proceeds generated from the issuance of the Company’s common stock pursuant to the Stock Purchase Agreement with TIAA Oil and Gas Investments, LLC, on
	August 6, 2013, were utilized to fund this acquisition and that such issuance occurred on February 1, 2012.  The pro forma results are not necessarily indicative of what actually would have occurred if the acquisition had been completed, or the common shares had been issued, as of February 1, 2012, nor are they necessarily indicative of future results.
	Oil and Natural Gas Property Additions
	During the three months ended April 30,  2014, we acquired oil and natural gas properties, and participated in the drilling and/or completion of wells, for total consideration of approximately $87.9 million.
	In the three months ended April 30, 2014, we capitalized  $1.2 million of internal land, geology and operations department costs directly associated with property acquisition, exploration (including lease record maintenance) and development.  In the three months ended April 30, 2013, we capitalized $0.7 million of internal land and geology costs directly associated with property acquisition, exploration (including lease record maintenance) and development.  The internal land and geology department costs were capitalized to unevaluated costs.
	Oilfield Services Equipment Additions
	Oilfield services equipment additions of $12.9  million during the three months ended April 30, 2014, consist primarily of the costs for two hydraulic fracturing spreads and other complementary well completion and workover equipment, $2.4 million of which was in service and $10.5 million of which was not yet placed in service at April 30, 2014.

	7.  EQUITY INVESTMENT
	The Company’s investment interest in Caliber is considered to be variable, and Caliber is considered to be a variable interest entity because the power to direct the activities that most significantly impact Caliber’s economic performance does not reside with the holders of equity investment at risk.  However, the Company is not considered the primary beneficiary of Caliber since it does not have the power to direct the activities of Caliber that are considered most significant to the economic performance of Caliber.  Under the equity method, our investment will be adjusted each period for contributions made, distributions received, the change in the fair value of our holdings of equity investment derivatives of Caliber and our share of Caliber’s comprehensive income and accretion of any basis difference.  Our maximum exposure to loss related to Caliber is limited to our equity investment as presented in the accompanying condensed consolidated balance sheet at April 30, 2014. We do not guarantee or otherwise support Caliber’s $200.0 million credit facility, and, as such, we would not have additional exposure associated with any borrowings on Caliber’s credit facility.
	We evaluate our equity method investments for impairment when events or changes in circumstances indicate there is a loss in value of the investment that is other than a temporary decline.
	As of April 30, 2014, the balance of the Company’s investment in Caliber was $79.0 million, which consisted of the following:

	TUSA Credit Facility
	On January 13, 2014, TUSA entered into Amendment No. 3 to the Amended and Restated Credit Agreement and Master Assignment ("Amendment No. 3") with Wells Fargo Bank, National Association (“Wells Fargo”), as administrative agent and issuing lender, and the other lenders named therein, as lenders. Amendment No. 3 amended that certain Amended and Restated Credit Agreement (the "A&R Credit Agreement"), dated April 11, 2013, as amended by that certain Amendment No. 1 to Amended and Restated Credit Agreement and Master Assignment, dated July 30, 2013, and that certain Amendment No. 2 to Amendment and Restated Master Assignment, dated October 16, 2013, to (i) broaden the definition of "Independent Engineering Report" to include a report prepared by or under the supervision of TUSA's engineers if certain requirements are satisfied, and (ii) increase the borrowing base under the TUSA Credit Facility from $275.0 million to $320.0 million.  The amendments in Amendment No. 1 remaining in force were (i) provisions permitting TUSA to hedge up to 85.0% of the anticipated production of (x) oil, (y) gas, and (z) natural gas liquid volumes, respectively, attributable to TUSA's total proved reserves, and (ii) revisions enabling TUSA to enter into a second lien credit facility at a future date.  The amendments in Amendment No. 2 remaining in force were (i) the addition of three new lenders under the facility, (ii) the extension of the maturity date to October 16, 2018, and (iii) the decrease of the applicable margins for ABR and Eurodollar advances by 0.25% at all utilization levels.  Further, the existing lenders assigned a portion of their lending commitments to the three new lenders.  As of April 30, 2014, TUSA, as borrower, had borrowings of $238.0 million outstanding under the A&R Credit Agreement, as amended by Amendment No. 3 (the “TUSA Credit Facility”).
	The borrowing base under the TUSA Credit Facility is subject to redetermination by the beginning of November 2014 and thereafter on a semi-annual basis by the beginning of each May and November.  In addition, TUSA has the option to request two additional redeterminations during any calendar year. In May 2014, the borrowing base was increased to $355.0 million (see Note 18 – Subsequent Events).
	Borrowings under the TUSA Credit Facility bear interest, at TUSA’s option, at either (i) the ABR (the highest of (A) the administrative agent’s prime rate, (B) the federal funds rate plus 0.5%, or (C) the one-month Eurodollar rate (as defined in the Credit Agreement) plus 1%,), plus an applicable margin that ranges between 0.50% and 1.50%, depending on TUSA’s utilization percentage of the then effective borrowing base, or (ii) the Eurodollar rate plus an applicable margin that ranges between 1.50% and 2.50%, depending on TUSA’s utilization percentage of the then effective borrowing base. TUSA may prepay borrowings under the TUSA Credit Facility at any time without premium or penalty (other than customary LIBOR breakage costs), subject to certain notice requirements. All borrowings under the TUSA Credit Facility mature on October 16, 2018.
	TUSA will pay a per annum fee on all letters of credit issued under the TUSA Credit Facility, which fee will equal the applicable margin for loans accruing interest based on the Eurodollar rate and a fronting fee to the issuing lender equal to 0.125% of the letter of credit amount. TUSA will pay a commitment fee that ranges between 0.375% and 0.50% per annum on the unused availability under the TUSA Credit Facility, depending on TUSA’s utilization percentage of the then effective borrowing base.
	The TUSA Credit Facility contains representations, warranties and covenants that are customary for similar credit arrangements, including, among other things, covenants relating to (i) financial reporting and notification, (ii) payment of obligations, (iii) compliance with applicable laws, and (iv) notification of certain events.  The TUSA Credit Facility also contains various covenants and restrictive provisions which may, among other things, limit TUSA's ability to sell assets, incur additional indebtedness, make investments or loans, and create liens.
	The TUSA Credit Facility contains financial covenants requiring TUSA to comply with the following: (i) TUSA must maintain a ratio of consolidated current assets to consolidated current liabilities (as those terms are defined in the TUSA Credit Facility) of at least 1.0 to 1.0; and (ii) the ratio of TUSA's consolidated debt to consolidated EBITDAX (as those terms are defined in the TUSA Credit Facility and determined as of the end of each fiscal quarter for the then most-recently ended four fiscal quarters) may not be greater than 4.0 to 1.0.  As of April 30, 2014, TUSA was in compliance with all financial covenants under the TUSA Credit Facility.
	Convertible Note
	On July 31, 2012, the Company sold to NGP Triangle Holdings, LLC a  $120.0 million Convertible Note (the “Convertible Note”) that became convertible after November 16, 2012 into the Company’s common stock at a conversion rate of one share per $8.00 of note principal (see Note 13  – Long-Term Debt in our audited financial statements included in our Fiscal 2014 Form 10-K).
	The Convertible Note accrues interest at a rate of 5.0% per annum, compounded quarterly, on each December 31, March 31, June 30 and September 30, and on the date of any redemption, conversion or exchange of the Convertible Note.  Such interest is paid-in-kind by adding to the principal balance of the Convertible Note, provided that, after July 31, 2017, the Company has the option to make such interest payments in cash.  As of April 30, 2014,  $10.9 million of accrued interest has been added to the principal balance of the Convertible Note.
	RockPile Credit Facility
	On March 25, 2014, RockPile entered into a Credit Agreement (the "FY2015 RockPile Credit Agreement") by and among RockPile, as borrower, Citibank, N.A. ("Citi"), as administrative agent and collateral agent, Wells Fargo Bank, National Association ("Wells Fargo"), as joint lead arranger and joint book runner with Citi, and the other lenders party thereto.  The FY2015 RockPile Credit Agreement is a $100.0 million senior secured revolving credit facility with an accordion feature that allows for the expansion of the facility up to an aggregate of $150.0 million.
	Borrowings under the FY2015 RockPile Credit Agreement bear interest, at RockPile's option, at either (i) the alternative base rate (the highest of (a) the administrative agent's prime rate, (b) the federal funds rate plus 0.5%, or (c) the one-month adjusted Eurodollar rate (as defined in the FY2015 RockPile Credit Agreement) plus 1.0%), plus an applicable margin that ranges between 1.5% and 2.25%, depending on RockPile's leverage ratio as of the last day of RockPile's most recent fiscal quarter, or (ii) the Eurodollar rate plus an applicable margin that ranges between 2.50% and 3.25%, depending on RockPile's leverage ratio as of the last day of RockPile's most recent fiscal quarter.  RockPile may prepay borrowings under the FY2015 RockPile Credit Agreement at any time without premium or penalty (other than customary LIBOR breakage costs), subject to certain notice requirements.  All borrowings under the FY2015 RockPile Credit Agreement mature on March 25, 2019.
	RockPile will pay a commitment fee that ranges between 0.375% and 0.50% per annum on the unused availability under the FY2015 RockPile Credit Agreement.  RockPile will also pay a per annum fee on all letters of credit issued under the FY2015 RockPile Credit Agreement, which will equal the applicable margin for loans accruing interest based on the Eurodollar rate and a fronting fee to the issuing lender equal to 0.125% of the letter of credit amount.  In connection with entering into the FY2015 RockPile Credit Agreement, RockPile paid certain upfront fees to the lenders thereunder, and RockPile paid certain arrangement and other fees to Citi and Wells Fargo.  Triangle is not a guarantor under the FY2015 RockPile Credit Agreement.  Upon entering into the FY2015 RockPile Credit Agreement, funds were drawn to pay off all outstanding borrowings under RockPile’s then outstanding Credit Agreement with Wells Fargo, and for working capital.  As of April 30, 2014, the interest rate on the loan was 5.0% and $44.6 million was outstanding on the loan.
	The RockPile Credit Facility contains financial covenants requiring RockPile to comply with the following: (i) the ratio of RockPile’s consolidated debt to EBITDA (as defined in the FY2015 RockPile Credit Facility) may not be greater than 2.75 to 1.00 (determined as of the end of each fiscal quarter for the then most-recently ended four fiscal quarters) and; (ii) RockPile must maintain a ratio of Adjusted EBITDA to Fixed Charges (as defined in the FY2015 RockPile Credit Facility) of at least 1.25 to 1.00 quarterly.  As of April 30, 2014, RockPile was in compliance with all financial covenants under the FY2015 RockPile Credit Facility.
	RockPile Mortgages Payable to Dacotah Bank
	Bakken Real Estate Development, LLC, a wholly-owned subsidiary of RockPile, has two mortgage loan agreements with Dacotah Bank in the amounts of $2.5 million, for its residential units, and $4.4 million, for its administrative and maintenance facility, all located in Dickinson, North Dakota.  The mortgage loans have a term of 15 years, bear interest at a variable rate equal to the Federal Home Loan Bank of Des Moines Five-Year Fixed-Rate Advance Rate plus 2.80%, and have a maturity date of
	December 15, 2028.
	RockPile Notes Payable to Sellers of Team Well Service, Inc.
	On October 16, 2013, RockPile issued two identical unsecured subordinated promissory notes to the sellers of Team Well Service Inc. (“Team Well”) in connection with its acquisition of Team Well.  The notes each have a face value of $0.5 million and bear interest at a fixed rate of 1.0%.   The loans have a maturity date of October 16, 2016, at which time the principal and accrued interest is due and payable.  The aggregate carrying value of the loans at April 30, 2014 was $0.9 million.  Over the term of the loans, the discount will be accreted on a monthly basis by increasing the carrying value of both notes and recording interest expense.
	RockPile Hauck Apartments Mortgage
	On November 20, 2013, RockPile closed on the purchase of a 12 unit apartment building in Dickinson, ND for a total purchase price of $1.8 million.  The purchase was funded by cash on hand and a mortgage from Dacotah Bank in the amount of $1.5 million.  The mortgage has a term of 15 years and bears interest at a variable rate equal to the Federal Home Loan Bank of Des Moines Five-Year Fixed-Rate Advance Rate plus 2.70%.   At April 30, 2014, the interest on the mortgage was 4.75% and the outstanding balance on the mortgage was $1.5 million.

	In regards to our commodity derivatives, the Company recorded a loss of $5.5 million for the three months ended April 30, 2014.   The Company recorded a gain on commodity derivative activities of $1.2 million for the three months ended April 30, 2013.  In regards to our equity investment derivatives, we recorded a gain of $10.5 million for the three months ended April 30, 2014.  The Company had no equity investment derivative activity during the three months ended April 30, 2013.
	Commodity Derivative Instruments
	Through TUSA, the Company has entered into commodity derivative instruments, as described below.  The Company has utilized costless collars and swaps to reduce the effect of price changes on a portion of our future oil production.  A collar requires us to pay the counterparty if the settlement price is above the ceiling price, and requires the counterparty to pay us if the settlement price is below the floor price.  The objective of the Company's use of derivative financial instruments is to achieve more predictable cash flows in an environment of volatile oil and natural gas prices and to manage its exposure to commodity price risk.  While the use of these derivative instruments limits the downside risk of adverse price movements, such use may also limit the Company's ability to benefit from favorable price movements.  The Company may, from time to time, add incremental derivatives to hedge additional production, restructure existing derivative contracts, or enter into new transactions to modify the terms of current contracts in order to realize the current value of the Company's existing positions.  The Company does not enter into derivative contracts for speculative purposes.
	The use of derivatives involves the risk that the counterparties to such instruments will be unable to meet the financial terms of such contracts.  The Company's derivative contracts are currently with four counterparties.  The Company has netting arrangements with the counterparties that provide for the offset of payables against receivables from separate derivative arrangements with the same underlier with the counterparties in the event of contract termination.  The derivative contracts may be terminated by a non-defaulting party in the event of default by one of the parties to the agreement.
	The Company's commodity derivative instruments are measured at fair value and are included in the accompanying condensed consolidated balance sheets as derivative assets and liabilities.  The Company has not designated any of its derivative contracts as fair value or cash flow hedges.  Therefore, the Company does not apply hedge accounting to its commodity derivative instruments.  Net gains and losses on derivative activities are recorded based on the changes in the fair values of the derivative instruments.  Net gains and losses on derivative activities are recorded in the gain (loss) from derivative activities line on the condensed consolidated statements of operations and comprehensive income.  The Company’s cash flow is only impacted when the actual settlements under the commodity derivative contracts result in making or receiving a payment to or from the counterparty.  These settlements under the commodity derivative contracts are reflected as operating activities in the Company’s condensed consolidated statements of cash flows.
	The Company's valuation estimate takes into consideration the counterparties' credit worthiness, the Company's credit worthiness, and the time value of money.  The consideration of the factors results in an estimated exit-price for each derivative asset or liability under a market place participant's view.  Management believes that this approach provides a reasonable, non-biased, verifiable, and consistent methodology for valuing commodity derivative instruments.
	The Company's commodity derivative contracts as of April 30, 2014 are summarized below:
	Term End Date		Contract Type		Basis (1)		Quantity (Bbl/d)		Weighted Average Put Strike	Weighted Average Call Strike		Weighted Average Price
	Fiscal 2015		Collar		NYMEX		4,836		$86.23	$100.04		-

	Equity Investment Derivatives
	As discussed in Note 7 – Equity Investment, the Company holds Class A Trigger Units, Class A Trigger Unit Warrants and Class A Warrants (Series 1 through Series 4) to acquire additional ownership in Caliber. These instruments are valued using the following valuation techniques that are generally less observable from objective sources.  As such, the Company has classified these instruments as Level 3.
	Class A Trigger Units
	As of April 30, 2014, the fair value of the Class A Trigger Units was assumed to be equal to the fair value of the underlying Class A Units of Caliber.  The fair value of the Caliber Class A Units and the Class A Trigger Units were determined based on the enterprise value of Caliber.  The enterprise value of Caliber was estimated employing primarily a discounted cash flow analysis.  The resulting value represented a marketable, minority value of Caliber.  As the Class A Units represent a non-marketable equity interest in a private enterprise, an adjustment to our preliminary value estimates was made to account for the lack of liquidity.  The concluded fair value of a single Class A Unit of Caliber was determined to be $11.28 at April 30, 2014, an increase of $1.28 per unit from January 31, 2014.  This increase in value resulted in a $7.0 million increase in the fair value of the Class A Trigger Units, resulting in an increase in our equity investment account in the accompanying unaudited condensed consolidated balance sheet as of
	April 30, 2014, and as a component of the gain reflected in the accompanying unaudited condensed consolidated statement of operations and comprehensive income in gain on equity investment derivatives.
	Class A Trigger Unit Warrant and Class A (Series 1 through Series 4) Warrants
	The fair value of the Class A Trigger Unit Warrant and the Class A (Series 1 through Series 4) Warrants as of April 30, 2014, were estimated using a Monte Carlo Simulation (“MCS”) model.  A MCS model provides a numeric approach to stochastic stock movement to forecast the future stock price of the underlying Class A Units, as opposed to an analytic solution provided by Black-Scholes.  For each MCS, the value of the Class A Units was forecasted at the end of each quarter based on a predetermined yield and the strike for the warrant is adjusted accordingly.  The model assumed that the warrants would be exercised at the earlier of (a) the contractual life of 12 years, and (b) the point at which the exercise price would be reduced to $5.00 per warrant (at which point it would be advantageous for Triangle to exercise early to capture future distributions on the Class A Units).  The key inputs to the MCS model are the same as the Black-Scholes model previously used including 10-year historical volatilities for publicly-traded comparable companies, risk-free interest rates over the expected warrant term and dividend yields based on expected distributions.  The change in fair value during the three months ended April 30, 2014 resulted in a $3.5 million increase in our equity investment account in the accompanying unaudited condensed consolidated balance sheet as of April 30, 2014, and as a component of the gain reflected in the accompanying unaudited condensed consolidated statement of operations and comprehensive income in gain on equity investment derivatives.

Fair Value Measurements	'
	10.  FAIR VALUE MEASUREMENTS
	The FASB’s ASC 820, Fair Value Measurement and Disclosure, establishes a hierarchy for inputs used in measuring fair value that maximizes the use of observable inputs and minimizes the use of unobservable inputs by requiring that the most observable inputs be used when available.  Observable inputs are inputs that market participants would use in pricing the asset or liability developed based on market data obtained from sources independent of the Company.  Unobservable inputs are inputs that reflect the Company's assumptions of what market participants would use in pricing the asset or liability developed based on the best information available in the circumstances.  The hierarchy is broken down into three levels based on the reliability of the inputs as follows:
		·		Level 1: Quoted prices are available in active markets for identical assets or liabilities;
		·		Level 2: Quoted prices in active markets for similar assets and liabilities that are observable for the asset or liability; and
		·		Level 3: Unobservable pricing inputs that are generally less observable from objective sources, such as discounted cash flow models or valuations.
	The financial assets and liabilities are classified based on the lowest level of input that is significant to the fair value measurement.  The Company's assessment of the significance of a particular input to the fair value measurement requires judgment, and may affect the valuation of the fair value of assets and liabilities and their placement within the fair value hierarchy levels.
	The following table presents the Company's financial assets and liabilities that were accounted for at fair value on a recurring basis as of April 30, 2014 and January 31, 2014 by level within the fair value hierarchy:
			As of April 30, 2014

	Liabilities:
	RockPile earn-out liability		$	-	$	-1,739	$	-	$	-1,739
	Commodity Derivative Instruments
	The Company determines its estimate of the fair value of its commodity derivative instruments using a market approach based on several factors, including quoted market prices in active markets, quotes from third parties, the credit rating of each counterparty, and the Company's own credit rating.  In consideration of counterparty credit risk, the Company assessed the possibility of whether the counterparty to the derivative would default by failing to make any contractually required payments.  The Company considers its counterparties to be of substantial credit quality and such counterparties have the financial resources and willingness to meet their potential repayment obligations associated with the derivative transactions.  At April 30, 2014, derivative instruments utilized by the Company consisted of costless collars and swaps.  The crude oil derivative markets are highly active.  Although the Company's derivative instruments are valued using public indices, the instruments themselves are traded with third-party counterparties and are not openly traded on an exchange.  As such, the Company has classified these instruments as Level 2.
	Caliber Class A Trigger Units, Class A Trigger Unit Warrant and Class A (Series 1 through Series 4) Warrants
	At April 30, 2014, the Caliber Class A Trigger Units and the Class A Trigger Unit Warrant and Class A (Series 1 through Series 4) Warrants are valued using valuation factors that are generally less observable from objective sources.  As such, the Company has classified these instruments as Level 3.  See Note 9 - Derivative Instruments for further discussion.
	RockPile Earn-out Liability
	The Company determined the estimated fair value of the earn-out liability relating to RockPile’s acquisition of Team Well using a market approach based on information derived from an analysis performed for RockPile by an independent third-party.  This analysis used publicly available information from market participants in the same industry, generally accepted methods for estimating an investor’s return requirements, and quoted market prices in active markets.  As such, the earn-out liability has been classified as Level 2.
	Convertible Note
	The Convertible Note had an estimated fair value at April 30, 2014 of $185.8 million, based on discounted cash flow analysis and option pricing (Level 3).  The increase in fair value from $169.2 million at January 31, 2014, is largely due to a greater option value for Triangle’s common stock based on an increase in the closing price of the stock to $9.62 per share at April 30, 2014 compared with $7.61 per share at January 31, 2014.
	Summary of Level 3 Financial Assets and Liabilities

	11.  COMMITMENTS AND CONTINGENCIES
	As of April 30, 2014, there were no known environmental or other regulatory matters related to the Company’s operations that were reasonably expected to result in a material liability other than asset retirement obligations which are reflected on the condensed consolidated balance sheet.  Non-compliance with environmental laws and regulations has not had, and is not expected to have, a material adverse effect on the Company’s financial position, results of operations or cash flows.
	As of April 30, 2014, the Company was subject to commitments on four drilling rig contracts.  The contracts expire between May 2014 and February 2015.  In the event of early termination of the contracts, the Company would be obligated to pay an aggregate amount of approximately $11.8 million as of April 30, 2014 as required under the terms of the contracts.
	Pursuant to the Third Amended and Restated Employment Agreement, dated July 4, 2013 (the "Employment Agreement"), between the Company and Jonathan Samuels, our President and Chief Executive Officer, Mr. Samuels is entitled to a cash bonus payable upon a liquidity event involving RockPile or Caliber based on the percentage gain realized by the Company relative to its initial investment in the relevant entity.  The amount of this bonus would be equivalent to 5.0% of that gain in Caliber for a Caliber liquidity event, and 3.5% of that gain in RockPile for a RockPile liquidity event.  The right to the bonus vests and becomes non-forfeitable in thirds on the first three anniversaries of the execution date of the Employment Agreement, with acceleration or forfeiture of the unvested portions of such right upon the occurrence of certain events.  Because consummation of a liquidity event involving RockPile or Caliber is contingent on many unknown factors, the Company has determined that the contingent liability associated with such a bonus is not probable at April 30, 2014, and, therefore, no amounts have been recorded in the accompanying condensed consolidated balance sheets.

	12.  CAPITAL STOCK
	Common Stock
	During the three months ended April 30, 2014, we issued 359,490 shares of the Company’s common stock (net of shares surrendered for related employee payroll tax withholding) for restricted stock units that vested during the period.
	Share-Based Compensation
	Effective January 28, 2009, the Company's Board of Directors approved a Stock Option Plan (the "Rolling Plan") whereby the number of authorized but unissued shares of common stock that may be issued upon the exercise of stock options granted under the Rolling Plan at any time could not exceed 10% of the issued and outstanding shares of common stock on a non-diluted basis at any time, and such aggregate number of shares of common stock available for issuance automatically increased or decreased as the number of issued and outstanding shares of common stock changed. Pursuant to the Rolling Plan, stock options became exercisable ratably in one-third increments on each of the first, second and third anniversaries of the date of the grant, and could be granted at an exercise price of not less than fair value of the common stock at the time of grant and for a term not to exceed ten years.
	Upon approval of the 2011 Omnibus Incentive Plan (the "2011 Plan") by the Company's stockholders on July 22, 2011, the Rolling Plan was terminated and no additional awards may be granted under the Rolling Plan. All outstanding awards under the Rolling Plan shall continue in accordance with their applicable terms and conditions.
	The 2011 Plan authorizes the Company to issue stock options, stock appreciation rights (“SARs”), restricted stock and restricted stock units, performance awards, stock or property, stock awards and other stock-based awards to any employee, consultant, independent contractor, director or officer of the Company and its subsidiaries.  The maximum number of shares of common stock reserved for issuance under the 2011 Plan is 5,900,000 shares, subject to adjustment for certain transactions.
	On July 4, 2013, the Company entered into a CEO Stand-Alone Stock Option Agreement with the Company's President and Chief Executive Officer (the "CEO Option Grant").  The CEO Option Grant is a stand-alone stock option agreement unrelated to the 2011 Plan.  As such, the CEO Option Grant required separate stockholder approval before any shares of the Company's common stock could be issued thereunder.  At the Company's Annual Meeting of Stockholders held on August 30, 2013, the CEO Option Grant was approved.
	Effective October 22, 2012, RockPile's Board of Managers approved the Second Amended and Restated Limited Liability Company Agreement, as further amended on February 20, 2013 ("RockPile LLC Agreement") which includes provisions allowing RockPile to issue an aggregate of up to 6.0 million Series B Units in multiple series designated by a sequential number (i.e., Series B-1, Series B-2, etc.) with the ability to re-issue forfeited or redeemed Series B Units.
	For the three months ended April 30, 2014 and 2013, the Company recorded stock based compensation related to restricted stock units, the CEO Option Grant and RockPile Series B Units as follows:
			Three Months Ended April 30,

	Compensation expense		$	2,008		$	1,595
	Restricted Stock Units
	During the three months ended April 30, 2014, the Company granted 771,350 restricted stock units as compensation to officers and employees.  The restricted stock units vest over one to five years.  As of April 30, 2014, there was approximately $18.4 million of total unrecognized compensation expense related to unvested restricted stock units.  This compensation expense is expected to be recognized over the remaining vesting period of the related awards of approximately 3.1 years.  When restricted stock units vest, the holder has the right to receive one share of the Company’s common stock per vesting unit.
	The following table summarizes the status of restricted stock units outstanding:
			Number of Shares		Weighted- Average Award Date Fair Value
	Restricted stock units outstanding - January 31, 2014		2,875,624		$	6.75

	The Company issued no stock options during the three months ended April 30, 2014.
	As of April 30, 2014, there was approximately $17.8 million of total unrecognized compensation expense related to stock options (including those issued under the CEO Option Grant and the Rolling Plan).  This compensation expense is expected to be recognized over the remaining vesting period of the related awards of approximately 4.5 years.  The following table summarizes the status of stock options outstanding:

	RockPile did not issue any Series B units during the three months ended April 30, 2014.
	A summary of RockPile’s total Series B units is as follows:
			Weighted Average (years)		Series B Units Outstanding, April 30, 2014		Vested		Unvested
	Series B-1 Unit Grants		0.34		3,100,000		2,566,667		533,333

	Total				4,070,000		2,581,667		1,488,333
	As of April 30, 2014, there was approximately $0.7 million of unrecognized compensation cost related to unvested Series B Units.  We expect to recognize such cost on a pro-rata basis on the Series B Units’ vesting schedule during the next three fiscal years.

Earnings Per Share [Abstract]	'
Earnings Per Share	'
	13.  EARNINGS PER SHARE
	Basic net income (loss) per common share is computed by dividing net income (loss) attributable to common stockholders by the weighted average number of common shares outstanding during the reporting period.  Diluted net income per common share reflects increases in average shares outstanding from the potential dilution, under the treasury stock method, that could occur upon (i) exercise of stock options, and (ii) vesting of restricted stock units.  The treasury stock method assumes exercise, vesting or conversion at the beginning of a period for securities outstanding at the end of a period.  Also, the treasury stock method for calculating dilution assumes that the increase in the number of shares is reduced by the number of shares which could have been repurchased by the Company at the quarter's average stock price using assumed proceeds from (a) the exercise cost of the options, and (b) the foregone future compensation expense of hypothetical early vesting of the outstanding restricted stock units.  The assumed proceeds are adjusted for income tax effects.
	The potential dilution from the conversion of the Convertible Note is determined using the “if converted” method whereby the shares issuable upon conversion are added to the denominator and the current period interest expense is added to the numerator, on an after-tax basis, to determine the dilutive effect had such conversion occurred at the beginning of the period.
	The table below sets forth the computations of net income per common share (basic and diluted) for the three months ended April 30, 2014 and 2013:
		For the Three Months Ended
		April 30,
	(in thousands, except per share data)	2014		2013
	Net income attributable to common stockholders	$	14,542	$	5,211

	Net income attributable to common stockholders after effect of debt conversion		15,460		5,211
	Basic weighted average common shares outstanding		85,951,910		52,605,152
	Effect of dilutive securities		17,362,426		398,749
	Diluted weighted average common shares outstanding		103,314,336		53,003,901
	Basic net income per share	$	0.17	$	0.10
	Diluted net income per share	$	0.15	$	0.10
	Of the stock options, restricted stock units and convertible debt outstanding at April 30, 2014, only the 6.0 million outstanding options in the CEO Option Grant were anti-dilutive for the three months ended April 30, 2014, and their underlying shares of common stock were excluded from the calculation of the diluted net income per share for that three-month period.  These awards could be potentially dilutive in future periods.

	14.  INCOME TAXES
	The effective tax rate for the three months ended April 30, 2014, was 40.8%, which differs from the statutory income tax rate due primarily to permanent book to tax differences and state income taxes.   Neither a tax expense nor a tax benefit was recognized for the three months ended April 30, 2013.
	As of April 30, 2014, the Company had no unrecognized tax benefits (or associated ASC 740-10-25 liabilities) for ASC 740-10-25 purposes.  The Company’s management does not believe that there are any new items or changes in facts or judgments that should impact the Company's ASC 740-10-25 position during the first quarter of fiscal year 2015.  Given the substantial net operating loss carry forwards at both the federal and state levels, neither significant interest expense nor penalties charged for any examining agents’ tax adjustments of income tax returns are anticipated, as any such adjustments would very likely adjust only net operating loss carry forwards.

	On September 12, 2013, TUSA and Caliber North Dakota amended and restated two midstream services agreements, which the parties originally entered into on October 1, 2012.  Caliber North Dakota is a wholly-owned subsidiary of Caliber.  The two original midstream services agreements were as follows:  (a) an agreement for crude oil gathering, stabilization, treating and redelivery, and (b) an agreement for (i) natural gas compression, gathering, dehydration, processing and redelivery; (ii) produced water transportation and disposal services; and (iii) fresh water transportation for TUSA’s oil and natural gas drilling and production operations.  The two agreements were revised to include an additional acreage dedication from TUSA to Caliber North Dakota and an increased firm volume commitment by Caliber North Dakota for each service line.  The revenue commitment language included in the original midstream services agreements was removed and replaced by a stand-alone agreement.
	TUSA maintained the commitment included in the original midstream services agreement to deliver minimum monthly revenues derived from the fees paid by TUSA to Caliber North Dakota for volumes of oil, natural gas, produced water, and fresh water for a primary term of 15 years beginning on the in-service date of the Caliber North Dakota facilities and added a commitment to deliver additional minimum monthly revenues derived from the fees paid by TUSA to Caliber North Dakota related to the increased acreage dedication and increased firm volume commitment.  The minimum commitment over the term of the agreements is $405.0 million.
	For the three months ended April 30, 2014, Caliber North Dakota had $4.0 million of revenue, $3.8 million of which was from TUSA, mainly comprised of fresh water and water disposal revenues.  See Note 7 – Equity Investment.
	For the three month period ended April 30, 2014, Triangle received $0.3 million from Caliber for administrative services supplemental to those provided by Caliber employees and pursuant to the October 1, 2012 Services Agreement between Triangle and Caliber.

Significant Changes In Proved Oil And Natural Gas Reserves	'
	17.  SIGNIFICANT CHANGES IN PROVED OIL AND NATURAL GAS RESERVES
	Our proved oil and natural gas reserves at April 30, 2014 increased from our proved oil and natural gas reserves at
	January 31, 2014.  Our proved reserves are in the Bakken and Three Forks formations in the North Dakota counties of McKenzie, Williams, Stark, Mountrail and Dunn and in Roosevelt county Montana.
	The reserve estimates at April 30, 2014 were estimated by our in-house reservoir engineer, who has been a Petroleum Engineer since 1995 and has over 19 years of experience.  Our reserve estimate at January 31, 2014 was audited by Cawley, Gillespie & Associates, Inc., an independent petroleum engineering firm.  Proved reserves are the estimated quantities of oil and natural gas, which by analysis of geoscience and engineering data, can be estimated with reasonable certainty to be economically producible from a given date forward, from known reservoirs, and under existing economic conditions, operating methods, and government regulations.  Existing economic conditions include prices and costs at which economic producibility from a reservoir is to be determined, and the price to be used is the average price during the 12-month period prior to the ending date of the period covered by the report, determined as an unweighted arithmetic average of the first-day-of-the-month price for each month within such period.  For the purposes of preparing the estimates of proved reserves presented below, such average prices were  $92.51 per barrel of oil, $46.41 per barrel of natural gas liquids and $5.32 per Mcf of natural gas for the reserves presented as of April 30, 2014.  For the reserves presented as of January 31, 2014, the average prices were  $93.09 per barrel of oil, $44.10 per barrel of natural gas liquids and $3.99 per Mcf of natural gas.

	Total Proved	100%	33,405	27,453	4,122	42,103	40,314
	The primary reason for the increase in proved reserves is the drilling and completion of wells in the first three months of fiscal year 2015.  Our net interest in proved developed wells increased 20% from 50.0 net wells at January 31, 2014 to 60.0 net wells at April 30, 2014, and our net interest in proved undeveloped locations decreased 13% from 52.5 net future development wells at January 31, 2014 to 45.7 net future development wells at April 30, 2014.

	Property Acquisition Agreements
	In May 2014, TUSA entered into two definitive purchase and sale agreements to acquire from unrelated third parties approximately 46,100 net acres and various other related rights, permits, contracts, equipment and other assets located in Williams County, North Dakota, Sheridan County, Montana, and Roosevelt County, Montana.  The aggregate purchase price is $135.0 million, subject to potential adjustments for each transaction including, but not limited to, adjustments for certain title and environmental defects, if any, as well as customary adjustments to reflect the operation of the oil and gas assets following the January 1, 2014 effective date and prior to the closing date.  The acquisitions are subject to customary closing conditions.  The Company anticipates using cash on hand, borrowings under the TUSA Credit Facility and an anticipated senior secured second lien term loan facility to fund the acquisitions.
	TUSA Credit Facility Amendments
	On May 9, 2014, TUSA entered into Amendment No. 4 to the Amended and Restated Credit Agreement and Joinder Agreement (“Amendment No. 4”) with Wells Fargo, as administrative agent and issuing lender, and the other lenders named therein, as lenders.  Amendment No. 4 amended the TUSA Credit Facility to (i) increase the borrowing base under the TUSA Credit Facility from $320.0 million to $355.0 million, (ii) add three new lenders to the facility, (iii) add a borrowing base redetermination by August 1, 2014, (iv) cause the borrowing base to increase by an additional $10.0 million upon closing an acquisition of certain oil and gas properties located in Williams County, North Dakota (“Acquisition No. 1”), (v) permit a one-time distribution to the Company of any funds contributed by the Company to TUSA in connection with closing Acquisition No. 1 (the “Permitted Distribution”), and (vi) permit TUSA to enter into a second lien credit facility of up to $100.0 million.
	On May 14, 2014, TUSA entered into Amendment No. 5 to the Amended and Restated Credit Agreement and Joinder Agreement (“Amendment No. 5”) with Wells Fargo, as administrative agent and issuing lender, and the other lenders named therein, as lenders.  Amendment No. 5 amended the TUSA Credit Facility, as amended by Amendment No. 4, to (i) cause the borrowing base to increase by an additional $40.0 million upon closing an acquisition of certain oil and gas properties located in Williams County, North Dakota, Sheridan County, Montana, and Roosevelt County, Montana (“Acquisition No. 2”), and (ii) amend the Permitted Distribution provision to include funds contributed by the Company to TUSA in connection with closing Acquisition No. 2.
	All other material terms of the TUSA Credit Facility were unchanged by Amendment No. 4 and Amendment No. 5.

Use of Estimates	'
	Use of Estimates
	The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities at the date of the financial statements, and the reported amounts of revenues and expenses during the reporting period.  Management believes the major estimates and assumptions impacting our condensed consolidated financial statements are the following:
		·	estimates of proved reserves of oil and natural gas, which affect the calculations of amortization and consideration of any possible impairment of capitalized costs of proved oil and natural gas properties;
		·	estimates of the fair value of unproved oil and natural gas properties we own and the consideration of any possible impairment;
		·	assumptions impacting our estimates as to the future realization of deferred income tax assets and the amount of our deferred tax liabilities;
		·	consideration of any impairment of our other long-term assets;
		·	depreciation of property and equipment; and
		·	valuation of derivative instruments.
	Actual results may differ from estimates and assumptions of future events.  Future production may vary materially from estimated oil and natural gas proved reserves.  Actual future prices may vary significantly from price assumptions used for determining proved reserves and for financial reporting.

	In May 2014, the Financial Accounting Standards Board issued Accounting Standards Update (“ASU”) 2014-09, Revenue from Contracts with Customers, issued as a new Topic, Accounting Standards Codification Topic 606.  The new revenue recognition standard provides a five-step analysis of transactions to determine when and how revenue is recognized.  The core principle of the guidance is that a company should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services.  This ASU is effective for the Company beginning in fiscal year 2017 and can be adopted by the Company either retrospectively or as a cumulative-effect adjustment as of the date of adoption.  We are currently evaluating the effect that adopting this new accounting guidance will have on our consolidated results of operations, cash flows and financial position.
	Accounting standard-setting organizations frequently issue new or revised accounting rules.  We regularly review new pronouncements to determine their impact, if any, on our condensed consolidated financial statements.  Other than the standard discussed above, there are no significant accounting standards applicable to Triangle which have not been adopted.
