| Pay vs Performance [Table Text Block] | | As discussed in the CD&A, our Compensation Committee has implemented an executive compensation program designed to link a substantial portion of our NEOs realized compensation to the achievement of our financial, operational and strategic objectives and to align our executive pay with changes in the value of our stockholders investments. We have identified Net Debt as our Company-Selected Measure that represents, in our view, the most important financial measure used to link Compensation Actually Paid ("CAP") to our performance in 2022. We believe our debt levels are important to our stockholders and our ability to reduce those debt levels is through generating higher cash flows and our focus on efficient operations. The following sets forth additional compensation information for our NEOs, calculated in accordance with SEC regulations for the fiscal years 2022, 2021, 2020: Year Summary Compensation Table Total for CEO (1) Compensation Actually Paid to CEO (2)(4) Average Summary Compensation Table for Remaining NEOs (3) Average Compensation Actually Paid to Remaining NEOs (2)(4) Value of Fixed $100 Investment Based on: Stated in millions Total Stockholder Return Peer Group Total Stockholder Return (5) Net Income (Loss) (6) Net Debt (7) (a) (b) (c) (d) (e) (f) (g) (h) (i) 2022 $ 7,930,872 $ 20,623,893 $ 2,658,371 $ 7,195,488 $ 518 $ 229 $ 1,183 $1,869 2021 $ 7,542,954 $ 29,861,807 $ 2,853,780 $ 10,803,072 $ 368 $ 159 $ 412 $2,736 2020 $ 6,704,788 $ 12,846,337 $ 2,755,736 $ 5,106,097 $ 138 $ 86 $ (712) $3,115 (1) The dollar amounts reported are the amounts of total compensation reported for our CEO, Mr. Ventura in the Summary Compensation Table ("SCT") as reflected on page 51. (2) The dollar amounts reported represent the amount of “compensation actually paid”, as computed in accordance with SEC rules. The dollar amounts do not reflect the actual amount of compensation paid to our CEO (or other NEOs) during the applicable year, but include (i) the year-end value of equity awards granted during the reported year and (ii) the change in the value of equity awards that were unvested at the end of the prior year, measured through the date the awards vested or were forfeited or through the end of the reported fiscal year. (3) Reflects compensation for our remaining NEOs, other than our CEO. (4) Time-vested restricted stock grant fair values are calculated using the stock price as of the date of grant. Adjustments have been made using the stock price as of the applicable year end and as of each date of vesting. TSR-PSUs fair values are calculated using a Monte Carlo simulation model as of the applicable year-end date or as of each date of vesting. Performance-Based Internal metrics fair value is calculated using the stock price as of the applicable year end multiplied by the probability of acheivement as of each such date. (5) Reflects cumulative total stockholder return for our Peer Group as described on page 38 of this proxy and assumes an initial investment of $100 on December 31, 2019. (6) Reflects net income (loss) in the Company's Consolidated Statements of Operations included in the Annual Reports on Form 10-K for each of the years ended December 31, 2022, 2021 and 2020. (7) Net debt is defined as total debt less cash on hand. Column (c).
