Canacol Energy, a natural gas exploration and production company with operations focused in Colombia, provides the following update concerning its current drilling activities and results.

Natilla-2 ST3 Exploration Well (SSJN-7 Exploration and Production contract 100% Working Interest)

Natilla-2 ST3 reached a total depth of 15,616 feet true vertical depth (“ft TVD”) near the base of the Porquero Formation (“Porquero”), the planned intermediate casing point of the well situated just above the underlying Cienega de Oro (“CDO”) sandstone primary target.  The well encountered the same over pressured gas charged Porquero sand intervals that were present in Natilla ST 1 and 2.  After drilling to the intermediate casing depth of 15,750 feet measured depth (“ft MD”) without issues, a hole cleaning trip was conducted prior to running casing.  During the hole cleaning trip, increased well bore instability and pressures were encountered that ultimately resulted in temporarily abandoning the well. 

The rig has been released as a forward plan is being prepared to evaluate options for re-entering the current well or drilling a new Natilla-3 well targeting the gas charged sandstones encountered in the various sidetracks of the Natilla-2 well.  The new drilling plan will incorporate drilling techniques to address the difficulty in running production liner across the over pressured gas charged sands encountered in the Porquero, and once addressed, continuing to deepen the well to the primary CDO sandstone reservoir target.

Borbon-1 Exploration Well (VIM-44 Exploration and Exploitation Contract, 100% Working Interest)

The Borbon-1 exploration well was spud on June 13, 2025, and reached a total depth of 10,751 ft MD on June 22, 2025.  The well encountered 157 ft TVD of gas pay with an average porosity of 18 % within the primary CDO sandstone reservoir target.  The well was cased and completed and will be brought on to production in early August 2025 once the flowline connecting the Sucre Norte platform, from which the Borbon, Zamia, and Palomino exploration wells are located, has been tied into the Jobo gas processing facility.  Initial production from the well is anticipated to be 10 to 12 million standard cubic feet per day (“MMscfpd”) based on the performance of offsetting producing CDO wells.

Zamia-1 Exploration Well (VIM-5 Exploration and Exploitation Contract, 100% Working Interest)

The Zamia-1 exploration well was spud on May 24, 2025, and reached a total depth of 11,454 ft MD on June 4, 2025.  The well encountered 32 ft TVD of gas pay with an average porosity of 22% within the primary CDO sandstone reservoir target.  The well was cased and completed and will be brought on production in early August 2025 once the flowline connecting the Sucre Norte platform has been tied into the Jobo gas processing facility.  Initial production from the well is anticipated to be 8 to 10 MMscfpd based on the performance of offsetting CDO producing wells.

Palomino-1 Exploration Well (VIM-44 Exploration and Exploitation Contract, 100% Working Interest)

The Palomino-1 exploration well is expected to spud within the next week and is targeting gas charged sands of the CDO reservoir in a prospect located approximately 2 kilometers to the south of the Borbon discovery.  The Corporation anticipates that the well will take approximately 3 weeks to drill and complete. If successful, the well will be brought onto production via the flowline connecting the Sucre Norte platform to the Jobo gas processing facility.
