Arrow Exploration brings Mateguafa HZ7 well online, delivers strong initial production in Colombia

Arrow Exploration CEO Marshall Abbott joined Steve Darling from Proactive to provide an operational update on activity at the Mateguafa Attic field, located on the Tapir Block in Colombia’s prolific Llanos Basin, where Arrow holds a 50% beneficial interest. The update highlighted the successful drilling, completion, and initial production performance of the Mateguafa HZ7 (M-HZ7) horizontal well. Abbott confirmed that the M-HZ7 well was spud on November 22, 2025, and reached its target depth on December 4, 2025. The well was drilled safely, on time, and on budget to a total measured depth of 14,253 feet, corresponding to a true vertical depth of 8,440 feet. During drilling, the well intersected multiple hydrocarbon-bearing intervals, reinforcing the prospectivity of the Mateguafa field. The company has now brought the M-HZ7 well onto production from the Carbonera C9 formation. The well includes approximately 4,053 feet of horizontal oil pay within a clean sandstone reservoir exhibiting strong reservoir characteristics, including an average porosity of 23% and high resistivity readings. Following perforation, an electric submersible pump (ESP) was installed to support production operations. In addition to the C9 interval, the well also encountered approximately 20 feet of net oil pay, on a true vertical depth basis, within the Carbonera C7 formation, providing further upside potential from stacked reservoirs in the field. The M-HZ7 well was initially placed on production at a heavily restricted setting, using a 25/128 choke and a pump frequency of 30 Hz. At these conservative conditions, the well is producing approximately 1,694 barrels of oil per day on a gross basis, or 847 barrels of oil per day net to Arrow. The produced oil has an API gravity of 30.6°, with a low water cut of approximately 4%, primarily attributed to completion fluids and minor formation water. Abbott noted that the well continues to clean up and that performance will be closely monitored as operating parameters are gradually optimized. Abbott also provided updates on the broader Mateguafa development program, including activity at the Mateguafa-6, Mateguafa-5, and Mateguafa-8 wells. Following the tie-in and production start-up of the M-8 well, Arrow plans to drill the Mateguafa-9 (M-9) well. This well is designed primarily as a delineation and water disposal well to support ongoing development across the Mateguafa area. The M-9 well will be the final well drilled under Arrow’s 2025 drilling program. It is planned as a large step-out well located outside the currently interpreted limits of the reservoir. While its primary purpose is water disposal, Abbott noted that the well could potentially become a producer if the reservoir extends beyond current seismic interpretations. After completing the M-9 well, Arrow intends to continue drilling additional horizontal and vertical development wells within the Mateguafa field before moving the rig to the Icaco prospect, where the company plans to drill its first exploration well at that location. #proactiveinvestors #arrowexplorationinc #aim #axl #tsxv #axl #ColombiaEnergy #MarshallAbbott #Q1Results #OilDrilling #EnergyInvestment #SeismicSurvey #WaterDisposal #PrepaymentDeal #ExplorationAndProduction #LlanosBasin #EnergySector #ProactiveInvestors
