Income Tax Disclosure [Abstract]  
The Company records its quarterly tax provision based on an estimate of the annual effective tax rate expected to apply to continuing operations for the various jurisdictions in which it operates. The tax effects of certain items, such as tax rate changes, significant unusual or infrequent items, and certain changes in the assessment of the realizability of deferred taxes, are recognized as discrete items in the period in which they occur and are excluded from the estimated annual effective tax rate.
For the three months ended March 31, 2021, the Company's estimated annual effective tax rate before discrete items was approximately 0% as a result of the valuation allowance on its deferred tax assets.
At each reporting period, the Company weighs all available positive and negative evidence to determine whether its deferred tax assets are more likely than not to be realized. A valuation allowance for deferred tax assets, including net operating losses, is recognized when it is more likely than not that some or all of the benefit from the deferred tax assets will not be realized. To assess that likelihood, the Company uses estimates and judgment regarding future taxable income and considers the tax laws in the jurisdiction where such taxable income is generated, to determine whether a valuation allowance is
required. Such evidence can include current financial position, results of operations, both actual and forecasted, the reversal of deferred tax liabilities and tax planning strategies as well as the current and forecasted business economics of the oil and gas industry. The cumulative loss in recent years is a significant piece of negative evidence that is hard to overcome and therefore the Company placed more reliance on historical results than forecasts. As a result of this analysis, the Company determined a full valuation allowance of $911.4 million was necessary against its net deferred tax asset as of March 31, 2021.
