Gran Tierra Energy Inc. Announces Positive Test Results from Bocachico Norte-J1

CALGARY, Alberta, Aug. 05, 2024 (GLOBE NEWSWIRE) -- Gran Tierra Energy Inc. ("Gran Tierra” or the "Company”) (NYSE American:GTE) (TSX:GTE) (LSE:GTE) today announced an operational update.  Production amounts are on an average working interest before royalties ("WI”) basis unless otherwise indicated. Per barrel ("bbl”) and bbl of oil per day ("BOPD”) amounts are based on WI sales before royalties.

Message to Shareholders

Gary Guidry, President and Chief Executive Officer of Gran Tierra, commented: "We are thrilled with the continued success of the Bocachico Norte-J1 well which marks the fourth consecutive oil discovery in Ecuador. These discoveries are a testament to our strong technical analysis and understanding of the geology, as well as our well-positioned land in the Oriente/Putumayo basin in Ecuador and Colombia. The production from the T-Sand and identified net pay in the B-Limestone and Basal Tena highlights the multi zone potential in our blocks. The presence of multiple producing zones and the ability to comingle production enhance our operational flexibility and economics. Together with the Arawana field, we expect these fields to be key drivers of production growth, reserve additions and free cash flow for the Company for years to come.”

Bocachico Norte-J1 Oil Discovery:

• Gran Tierra has run production casing, cemented and perforated the T-Sand oil zone and has begun production testing.
• The T-Sand was perforated over 20 ft of reservoir with 29 ft of reservoir pay based on log evaluation. A jet pump was run and the well has produced at stabilized rates over 51 hours at 1,353 barrels oil per day ("BOPD”), 35.5-degree API gravity oil, less than 1% water cut, and a gas-oil ratio of 336 standard cubic feet per stock tank barrel.
• This positive test in the T-Sand builds confidence in the multizone potential (Basal Tena / U-Sand / T-Sand) for the Zabaleta well which is expected to be drilled in the second half of 2024 and is 200 feet up dip from the recent Arawana discovery well. Arawana continues to produce with strong results from the Basal Tena zone greater than 900 bopd. The artificial lift system will be converted from a jet pump to electrical submersible pump in the third quarter of 2024. The cumulative production to date from Arawana is approximately 74,000 bbl.
• This test verifies the Bocachico structure potential in the T-Sandstone and continues to diversify the corporate producing product stream to lighter hydrocarbons.

All statements other than statements of historical facts included in this press release regarding expectations regarding drivers of production growth, reserves additions and free cash flow for the Company; anticipated timing of the drilling of the Zabaleta well, and those statements preceded by, followed by or that otherwise include the words "expect,” "plan,” "can,” "will,” "should,” "guidance,” "forecast,” "budget,” "estimate,” "signal,” "progress” and "believes,” derivations thereof and similar terms identify forward-looking statements. In particular, but without limiting the foregoing, this press release contains forward-looking statements regarding: the Company’s drilling program and the Company’s expectations regarding drivers of production growth, reserves additions and free cash flow. The forward-looking statements contained in this press release reflect several material factors and expectations and assumptions of Gran Tierra including, without limitation, that Gran Tierra will continue to conduct its operations in a manner consistent with its current expectations, pricing and cost estimates (including with respect to commodity pricing and exchange rates), the general continuance of assumed operational, regulatory and industry conditions in Colombia and Ecuador, and the ability of Gran Tierra to execute its business and operational plans in the manner currently planned.

Among the important factors that could cause our actual results to differ materially from the forward-looking statements in this press release include, but are not limited to, the risk factors detailed from time to time in Gran Tierra’s periodic reports filed with the Securities and Exchange Commission, including, without limitation, under the caption "Risk Factors” in Gran Tierra’s Annual Report on Form 10-K for the year ended December 31, 2023 filed February 20, 2024 and its other filings with the SEC.

Presentation of Oil and Gas Information

References to a formation where evidence of hydrocarbons has been encountered is not necessarily an indicator that hydrocarbons will be recoverable in commercial quantities or in any estimated volume. Gran Tierra’s reported production is a mix of light crude oil and medium and heavy crude oil for which there is not a precise breakdown since the Company’s oil sales volumes typically represent blends of more than one type of crude oil. Well test results should be considered as preliminary and not necessarily indicative of long-term performance or of ultimate recovery. Well log interpretations indicating oil and gas accumulations are not necessarily indicative of future production or ultimate recovery. If it is indicated that a pressure transient analysis or well-test interpretation has not been carried out, any data disclosed in that respect should be considered preliminary until such analysis has been completed. References to thickness of "oil pay” or of a formation where evidence of hydrocarbons has been encountered is not necessarily an indicator that hydrocarbons will be recoverable in commercial quantities or in any estimated volume.
