| Accounting Policies [Abstract] | |
| Use of Estimates | We have made several estimates and assumptions
related to the reporting of our consolidated assets and liabilities and to the disclosure of contingent assets and liabilities
to prepare these consolidated financial statements in conformity with GAAP. We believe our current estimates are reasonable and
appropriate; however, actual results could differ from those estimated. |
| Cash and Cash Equivalents | Cash and cash equivalents represent liquid investments
with an original maturity of three months or less. Cash balances are maintained in depository and overnight investment accounts
with financial institutions that, at times, may exceed insured deposit limits. We monitor the financial condition of the financial
institutions and have experienced no losses associated with these accounts. |
| Restricted Cash | Restricted cash, current portion primarily represents
a payment reserve account held by Veritex as security for payments under a loan agreement. Restricted cash, noncurrent represents
funds held in the Veritex disbursement account for payment of construction related expenses to complete building new petroleum
storage tanks. |
| Accounts Receivable and Allowance for Doubtful Accounts | Accounts receivable are presented net of any
necessary allowance(s) for doubtful accounts. Receivables are recorded at the invoiced amount and generally do not bear interest.
An allowance for doubtful accounts is established, when necessary, based on prior experience and other factors which,
in management's judgment, deserve consideration in estimating bad debts. Management assesses collectability primarily based
on the current aging status of the customer's account, our historical collection experience with the customer, and
the customer's financial condition. Based on a review of these factors, management establishes or adjusts the allowance
for specific customers and the accounts receivable portfolio as a whole. We had an allowance for doubtful accounts of
$0.1 million at both September 30, 2019 and December 31, 2018. |
| Inventory | Our inventory primarily consists of refined
petroleum products, crude oil and condensate, and chemicals. Inventory is valued at lower of cost or net realizable value with
cost being determined by the average cost method, and net realizable value being determined based on estimated selling prices less
any associated delivery costs. If the net realizable value of our refined petroleum products inventory declines to an amount less
than our average cost, we record a write-down of inventory and an associated adjustment to cost of goods sold. (See “Note
(7) Inventory” for additional disclosures related to our inventory.) |
| Property and Equipment | Refinery and Facilities We record refinery and facilities at cost less
any adjustments for depreciation or impairment. Adjustment of the asset and the related accumulated depreciation accounts are made
for the refinery and facilities asset’s retirement and disposal, with the resulting gain or loss included in the consolidated
statements of operations. For financial reporting purposes, depreciation of refinery and facilities assets is computed using the
straight-line method using an estimated useful life of 25 years beginning when the refinery and facilities assets are placed in
service. We did not record any impairment of our refinery and facilities assets for the periods presented. Pipelines and Facilities Oil and Gas Properties Construction in Progress (See “Note (8) Property, Plant and Equipment,
Net” for additional disclosures related to our refinery and facilities assets, oil and gas properties, pipelines and facilities
assets, and construction in progress.) |
| Revenue Recognition | We adopted the provisions of FASB ASU (defined
below) 2014-09, Revenue from Contracts with Customers (ASC 606) Refinery Operations Revenue We consider a variety of facts and circumstances
in assessing the point of control transfer, including but not limited to: whether the purchaser can direct the use of the refined
petroleum product, the transfer of significant risks and rewards, our rights to payment, and transfer of legal title. In each case,
the term between the sale and when payment is due is not significant. Transportation, shipping, and handling costs incurred are
included in cost of goods sold. Excise and other taxes that are collected from customers and remitted to governmental authorities
are not included in revenue. Tolling and Terminaling Revenue We typically satisfy performance obligations
for tolling and terminaling operations with the passage of time. We determine the transaction price at agreement inception based
on the guaranteed minimum amount of revenue over the term of the agreement. We allocate the transaction price to the single performance
obligation that exists under the agreement, and we recognize revenue in the amount for which we have a right to invoice. Generally,
payment terms do not exceed 30 days. Revenue from tank storage customers may, from
time to time, include fees for ancillary services, such as in-tank and tank-to-tank blending. These services are considered optional
to the customer, and the price we charge for such services is not included in the fixed cost under the customer’s tank storage
agreement. Ancillary services are considered a separate performance obligation by us under the tank storage agreement. The performance
obligation is satisfied when the requested service has been performed in the applicable period. |
| Income Taxes | We account for income taxes under FASB ASC guidance
related to income taxes, which requires recognition of income taxes based on amounts payable with respect to the current reporting
period and the effects of deferred taxes for the expected future tax consequences of events that have been included in our financial
statements or tax returns. Under this method, deferred tax assets and liabilities are determined based on the differences
between the financial accounting and tax basis of assets and liabilities, as well as for operating losses and tax credit carryforwards
using enacted tax rates in effect for the year in which the differences are expected to reverse. As of each reporting date, management considers
new evidence, both positive and negative, to determine the realizability of deferred tax assets. Management considers whether it
is more likely than not that a portion or all of the deferred tax assets will be realized, which is dependent upon the generation
of future taxable income prior to the expiration of any net operating loss (“NOL”) carryforwards. When management determines
that it is more likely than not that a tax benefit will not be realized, a valuation allowance is recorded to reduce deferred tax
assets. A significant piece of objective negative evidence evaluated was cumulative losses incurred over the three-year period
ended December 31, 2018. Such objective evidence limits the ability to consider other subjective evidence, such as projections
for future growth. Based on this evaluation, we recorded a valuation allowance against the deferred tax assets for which realization
was not deemed more likely than not as of September 30, 2019 and December 31, 2018. We expect to recover deferred tax assets related
to the Alternative Minimum Tax (“AMT”) credit carryforwards. In addition, we have NOL carryforwards that remain available
for future use. The benefit of an uncertain tax position is
recognized in the financial statements if it meets a minimum recognition threshold. A determination is first made as to whether
it is more likely than not that the income tax position will be sustained, based upon technical merits, upon examination by the
taxing authorities. If the income tax position is expected to meet the more-likely-than-not criteria, the benefit recorded in the
financial statements equals the largest amount that is greater than 50% likely to be realized upon its ultimate settlement. At
September 30, 2019 and December 31, 2018, there were no uncertain tax positions for which a reserve or liability was necessary.
(See “Note (16) Income Taxes” for further information related to income taxes.) |
| Impairment or Disposal of Long-Lived Assets | In accordance with FASB ASC guidance on accounting
for the impairment or disposal of long-lived assets, we periodically evaluate our long-lived assets for impairment. Additionally,
we evaluate our long-lived assets when events or circumstances indicate that the carrying value of these assets may not be recoverable.
The carrying value is not recoverable if it exceeds the sum of the undiscounted cash flows expected to result from the use and
eventual disposition of the asset or group of assets. If the carrying value exceeds the sum of the undiscounted cash flows, an
impairment loss equal to the amount by which the carrying value exceeds the fair value of the asset or group of assets is recognized.
Significant management judgment is required in the forecasting of future operating results that are used in the preparation of
projected cash flows and, should different conditions prevail or judgments be made, material impairment charges could be necessary.
As a result of the Final Arbitration Award, which represents a significant adverse change that could affect the value of a long-lived
asset, management performed potential impairment testing of our refinery and facilities assets in the fourth quarter of 2018. Upon
completion of that testing, we determined that no impairment was necessary at December 31, 2018. We did not record any impairment
of our refinery and facilities assets for the periods presented. |
| Asset Retirement Obligations | FASB ASC guidance related to asset retirement
obligations (“AROs”) requires that a liability for the discounted fair value of an ARO be recorded in the period in
which incurred, and the corresponding cost capitalized by increasing the carrying amount of the related long-lived asset. The liability
is accreted towards its future value each period, and the capitalized cost is depreciated over the useful life of the related asset.
If the liability is settled for an amount other than the recorded amount, a gain or loss is recognized. Management has concluded that there is no legal
or contractual obligation to dismantle or remove the refinery and facilities assets. Further, management believes that these assets
have indeterminate lives under FASB ASC guidance for estimating AROs because dates or ranges of dates upon which we would retire
these assets cannot reasonably be estimated at this time. When a legal or contractual obligation to dismantle or remove the refinery
and facilities assets arises and a date or range of dates can reasonably be estimated for the retirement of these assets, we will
estimate the cost of performing the retirement activities and record a liability for the fair value of that cost using present
value techniques. We recorded an ARO liability related to future
asset retirement costs associated with dismantling, relocating, or disposing of our offshore platform, pipeline systems, and related
onshore facilities, as well as for plugging and abandoning wells and restoring land and sea beds. The cost estimates for each of
our assets were developed based upon regulatory requirements, structural makeup, water depth, reservoir characteristics, reservoir
depth, equipment demand, current retirement procedures, and construction and engineering consultations. Estimating future costs
are difficult and require management to make judgments that are subject to future revisions based upon numerous factors, including
changing technology, political, and regulatory environments. We review our assumptions and estimates of future abandonment costs
on an annual basis. (See “Note (13) Asset Retirement Obligations” for additional information related to our AROs.) |
| Computation of Earnings Per Share | We apply the provisions of FASB ASC guidance
for computing earnings per share (“EPS”). The guidance requires the presentation of basic EPS, which excludes dilution
and is computed by dividing net income available to common stockholders by the weighted-average number of shares of common stock
outstanding for the period. The guidance requires dual presentation of basic EPS and diluted EPS on the face of our consolidated
statements of operations and requires a reconciliation of the denominator of basic EPS and diluted EPS. Diluted EPS is computed
by dividing net income available to common stockholders by the diluted weighted average number of common shares outstanding, which
includes the potential dilution that could occur if securities or other contracts to issue shares of common stock were converted
to common stock that then shared in the earnings of the entity. The number of shares related to options, warrants,
restricted stock, and similar instruments included in diluted EPS is based on the “Treasury Stock Method” prescribed
in FASB ASC guidance for computation of EPS. This method assumes theoretical repurchase of shares using proceeds of the respective
stock option or warrant exercised, and, for restricted stock, the amount of compensation cost attributed to future services that
has not yet been recognized and the amount of any current and deferred tax benefit that would be credited to additional paid-in-capital
upon the vesting of the restricted stock, at a price equal to the issuer’s average stock price during the related earnings
period. Accordingly, the number of shares includable in the calculation of EPS in respect of the stock options, warrants, restricted
stock, and similar instruments is dependent on this average stock price and will increase as the average stock price increases.
(See “Note (17) Earnings Per Share” for additional information related to EPS.) |
