Arrow Exploration Co. will place Llanos basin Rio Cravo Sur-1 (RCS-1) on production in Tapir block, Colombia, after a successful test of an isolated zone.
RCS-1 was spud May 23, 2022, and targeted a three-way fault bounded structure with multiple high-quality reservoir objectives. The well was drilled to a total measured depth of 8,656 ft (8,105 ft true vertical depth) and encountered six hydrocarbon bearing intervals totaling 55 net ft of oil pay.
The Carbonera C7B zone tested at 1,872 bo/d peak rate of 30° API crude. The zone was tested on June 22 for 33 hours at an average rate of 1,076 bo/d.
The deeper Ubaque zone tested at 184 bo/d peak rate of 12-13 API° crude. The zone was tested June 13 for 38.5 hours at an average rate of 33 bo/d.
Based on test results, the well will produce from zone C7B. Arrow decided not to test uphole C7 zones and Gacheta C as they had proved to be oil bearing in RCE-2. The test of Gacheta B zone was cut short due to formation water production.
Arrow is operator at Tapir block with 50% working interest.
