Arrow starts producing from fourth Ubaque well

Sept. 23, 2024
Arrow Exploration started production from the fourth well on Carrizales Norte B pad in Tapir block onshore Colombia.

Arrow Exploration Corp. started production from the fourth well on the Carrizales Norte B (CNB) pad in Tapir block, Llanos basin, onshore Colombia.

CNB HZ-5 spudded on Aug. 22, 2024, and reached a target depth of 8,472 ft TVD into the Ubaque formation on Sept. 7, 2024. The well was drilled to a total measured depth of 13,350 ft with a horizontal section of about 4,070 ft.

CNB HZ-5 came on production on Sept. 15, 2024, with the use of an electric submersible pump (ESP) flowing at a gross rate exceeding 2,700 bo/d (1,350 bo/d net to Arrow). Production continues to increase. The well currently has an 11% water cut. 

CNB HZ-5 is the second Arrow well to use autonomous inflow control devices designed to limit the water cut in horizontal wells. Results from CNB HZ-4 and HZ-5 are being monitored to determine if these technologies, or others, will enhance production and ultimate recovery in the Ubaque reservoir.

The first three horizontal wells (CNB HZ-1, HZ-3, and HZ-4) on the pad continue to perform above expectations with 1,600-2,120 bo/d gross flow rates and 13-52% water cuts.

The Petroworks rig is being moved to the sixth cellar on the pad where Arrow plans to spud the fifth horizontal well (CNB HZ-6). After that, the company expects to drill one additional horizontal well on the B pad, followed by the Chorreron-1 exploration well (formerly known as Baquiano-1), which is on trend with Carrizales Norte field.

The Canadian company will drill 15 wells focused on Tapir block and the development of Carrizales Norte field in the block’s eastern plains (OGJ Online, Jan. 9, 2024).

Arrow holds 50% interest in Tapir block.
