As of this date, all outstanding stock options are to be net settled in cash resulting in a change in classification of stock options from equity to liability. On May 1, 2024, the Company recorded a liability of $4.4 million and an additional stock-based compensation costs of $0.4 million related to the modification of the stock option plan. As at September 30, 2024, the equity compensation award liability on the Company’s balance sheet included $1.7 million of current liability and $0.2 million of long-term liability related to the Company’s outstanding stock options. The fair value of each stock option award was estimated on the modification date using the Black-Scholes-Merton option-pricing model based on the assumptions noted in the following table: Fair value of option modification $0.00 - $6.11 Dividend yield (per share) Nil Expected volatility 43% to 87% Risk-free interest rate 4.6% to 5.1% Expected term 0.1 - 4.9 years Expected forfeiture rate 0% to 5% For the three and nine months ended September 30, 2024, there was $3.1 million of stock-based compensation recovery and $6.4 million of stock-based compensation expense, respectively (three and nine months ended September 30, 2023, $1.9 million and $3.7 million of stock-based compensation expense, respectively). As at September 30, 2024, there was $17.3 million (December 31, 2023 - $8.6 million) of unrecognized compensation costs related to unvested PSUs, RSUs and stock options, which are expected to be recognized over a weighted-average period of 1.9 years. During the nine months ended September 30, 2024, the Company paid out $10.4 million for PSUs vested on December 31, 2023 (nine months ended September 30, 2023 - $15.1 million for PSUs vested on December 31, 2022). During the three and nine months ended September 30, 2024, the Company awarded nil and 0.5 million RSUs to employees pursuant to the existing 2007 Equity Incentive Plan, respectively. Under the 2007 Equity Incentive Plan, RSUs will vest one-third each year over a three-year period. Upon vesting, RSUs entitle the holder to receive either the underlying number of shares of the Company’s Common Stock or a cash payment equal to the value of the underlying shares of the Company’s Common Stock. The Company intends to settle RSUs outstanding as at September 30, 2024, in cash. Net Income (Loss) per Share Basic net income or loss per share is calculated by dividing net income or loss attributable to common shareholders by the weighted average number of shares of Common Stock issued and outstanding during each period. Diluted net income or loss per share is calculated using the treasury stock method for share-based compensation arrangements. The treasury stock method assumes that any proceeds obtained on the exercise of share-based compensation arrangements would be used to purchase shares of Common Stock at the average market price during the period. The weighted average number of shares is then adjusted by the difference between the number of shares issued from the exercise of share-based compensation arrangements and shares re-purchased from the related proceeds. Anti-dilutive shares represent potentially dilutive securities excluded from the computation of diluted income or loss per share as their impact would be anti-dilutive. Weighted Average Shares Outstanding Three Months Ended September 30, Nine Months Ended September 30, 2024 2023 2024 2023 Weighted average number of shares of Common Stock outstanding 30,732,807 33,287,368 31,273,861 33,675,160 Shares issuable pursuant to stock options — 129,299 — — Shares assumed to be purchased from proceeds of stock options — (66,617) — — Weighted average number of diluted shares of Common Stock outstanding 30,732,807 33,350,050 31,273,861 33,675,160 For the three and nine months ended September 30, 2024 all options, on a weighted average basis (three and nine months ended September 30, 2023, 1,854,307 and all options, respectively) were excluded from the diluted income (loss) per share calculation as the options were anti-dilutive.

Revenue

Revenue from Contract with Customer [Abstract]
Revenue	Revenue The Company’s revenues are generated from oil sales at prices that reflect the blended prices received upon shipment by the purchaser at defined sales points or defined by contract relative to ICE Brent and adjusted for Vasconia or Castilla (Colombia sales) or Oriente (Ecuador sales) crude differentials, quality and transportation discounts and premiums each month. For the three and nine months ended September 30, 2024, 100% of the Company’s revenue resulted from oil sales (three and nine months ended September 30, 2023 - 100%). During the three and nine months ended September 30, 2024, quality and transportation discounts were 18% and 17% of the average ICE Brent price (three and nine months ended September 30, 2023 - 14% and 18%), respectively. During the three and nine months ended September 30, 2024, the Company’s production was sold to one major customer in Colombia and Ecuador, representing 100% of the total sales volumes (three and nine months ended September 30, 2023 - one major customer representing 96% and 97% of the total sales volumes, respectively).

Income Tax Disclosure [Abstract]
Taxes	Taxes The Company’s effective tax rate was 44% for the nine months ended September 30, 2024, compared to 115% in the corresponding period of 2023. Current income tax expense was $61.4 million for the nine months ended September 30, 2024, compared to $63.7 million in the corresponding period of 2023, due to lower taxable income in Colombia, partially offset by additional current tax expense related to a tax planning strategy. For the nine months ended September 30, 2024, the deferred income tax was a recovery of $32.3 million, primarily as a result of the recognition of additional tax losses resulting from a tax planning strategy, which were partially offset by tax depreciation being higher than accounting depreciation and the use of tax losses to offset taxable income in Colombia. For the nine months ended September 30, 2023, the deferred income tax expense was $43.2 million compared to $36.9 million in the corresponding period of 2022. In each case, primarily attributable to higher tax depreciation compared to accounting depreciation and the utilization of tax losses to offset taxable income in Colombia. For the nine months ended September 30, 2024, the difference between the effective tax rate of 44% and the 50% Colombian tax rate was primarily due to a lower impact of foreign taxes, 2022 true-up related to tax planning strategy and non-taxable foreign exchange adjustments. These were partially offset by an increase in valuation allowance, other permanent differences, non-deductible stock-based compensation and non-deductible royalties in Colombia. The Company strategically revised its 2022 tax return to use its tax receivable balance to offset current tax liabilities, rather than applying net operating loss carryforwards. This decision was driven by the expectation of higher future income tax rates and increased profitability. As a result, there was an increase in current tax expense which was offset by long-term tax receivable, ensuring no impact on cash flows. This approach preserved the Company’s net operating loss carryforward for future periods, providing greater tax benefits and flexibility in recovering tax receivables, while strengthening our equity position. For the nine months ended September 30, 2023, the difference between the effective tax rate of 115% and the 50% Colombian tax rate was primarily due to an increase in non-deductible foreign exchange adjustments, the impact of foreign taxes, non-deductible royalties in Colombia and non-deductible stock-based compensation. These were partially offset by a decrease in valuation allowance.

Fair Value Disclosures [Abstract]
Financial Instruments and Fair Value Measurement	Financial Instruments and Fair Value Measurement Financial Instruments Financial instruments are initially recorded at fair value, defined as the price that would be received to sell an asset or paid to market participants to settle liability at the measurement date. For financial instruments carried at fair value, GAAP establishes a fair value hierarchy that prioritizes the inputs to valuation techniques used to measure fair value. This hierarchy consists of three broad levels: • Level 1 - Inputs representing quoted market prices in active markets for identical assets and liabilities • Level 2 - Inputs other than quoted prices included within Level 1 that are observable for the assets and liabilities, either directly or indirectly • Level 3 - Unobservable inputs for assets and liabilities At September 30, 2024, the Company’s financial instruments recognized on the balance sheet consist of cash and cash equivalents, restricted cash and cash equivalents, accounts receivable, accounts payable and accrued liabilities, current portion of long-term debt, long-term debt and other long-term liabilities. The Company uses appropriate valuation techniques based on the available information to measure the fair values of assets and liabilities. Fair Value Measurement The following table presents the Company’s fair value measurements of its financial instruments as of September 30, 2024, and December 31, 2023: (Thousands of U.S. Dollars) As at September 30, 2024 As at December 31, 2023 Level 1 Assets Prepaid equity forward (“PEF”) - current (1) $ — $ 5,630 Liabilities 6.25% Senior Notes $ 23,804 $ 22,994 7.75% Senior Notes 21,388 20,744 9.50% Senior Notes 701,632 429,018 $ 746,824 $ 472,756 Level 2 Assets Restricted cash and cash equivalents - long-term (2) $ 7,093 $ 7,750 Liabilities Credit facility $ — $ 35,609 (1) The current portion of PEF is included in the other current assets on the Company’s condensed consolidated balance sheet. (2) The long-term portion of restricted cash and cash equivalents is included in the other long-term assets on the Company’s condensed consolidated balance sheet. The fair values of cash and cash equivalents, current restricted cash and cash equivalents, accounts receivable and accounts payable and accrued liabilities approximate their carrying amounts due to the short-term maturity of these instruments. Restricted Cash and Cash Equivalents - Long-Term The fair value of long-term restricted cash and cash equivalents approximate its carrying value because interest rates are variable and reflective of market rates. Prepaid Equity Forward As at September 30, 2024, the Company had no outstanding PEF asset (As at December 31, 2023 - 1.0 million notional shares with a fair value of $5.6 million). For the three and nine months ended September 30, 2024, the Company recorded nil and a $0.3 million loss, respectively, in general and administrative expenses relating to the PEF (three and nine months ended September 30, 2023 - $2.2 million gain and $3.6 million loss, respectively). During the nine months ended September 30, 2024, the Company settled all outstanding notional PEF shares and received net proceeds of $5.1 million resulting in a $0.3 million loss on settlement. Senior Notes Financial instruments recorded at amortized cost at September 30, 2024, were the Senior Notes (Note 5). At September 30, 2024, the carrying amounts of the 6.25% Senior Notes, 7.75% Senior Notes and 9.50% Senior Notes were $24.8 million, $23.8 million, and $674.3 million, respectively, which represented the aggregate principal amounts less unamortized debt issuance costs and discounts, and the fair values were $23.8 million, $21.4 million, and
