(Oilandgaspress) Arrow Exploration Corp. the high-growth operator with a portfolio of assets across key Colombian hydrocarbon basins, provided an update on the operational activity at the Carrizales Norte (“CN”) field on the Tapir Block in the Llanos Basin of Colombia where Arrow holds a 50 percent beneficial interest.
CN-1. The CN-1 well was spud on May 1, 2023, and reached target depth on May 11, 2023. CN-1 was the first well drilled into the CN field and results from this well have confirmed the productive potential of the multi-pool field. The well was drilled to a total measured depth of 9,190 feet (8,511 feet true vertical depth) and encountered multiple hydrocarbon-bearing intervals.
Arrow has completed the final test on the CN-1 well in the C7 formation which has approximately 26 feet of net oil pay. The pay zone is a clean sandstone exhibiting consistent 30% porosity and high resistivities. An electric submersible pump (ESP) has been inserted in the well after perforating.
Specific data for the production test on the C7 formation are as follows:
· The production test took place over a 62-hour period.
· The well was tested at three different flow rates to evaluate productivity and to plan for water cut management.
o The first flow period was held for 12 hours and showed an average oil rate of 662 BOPD gross,
o The second flow period was for 32 hours and showed an average oil rate of 902 BOPD gross, and,
o The third flow period was held for 17 hours and showed an average oil rate of 1,134 BOPD gross.
· Oil production tested at a peak rate of 1,272 BOPD, and a final stabilized rate of 1,134 BOPD gross.
In the final 24 hours of the test, CN-1 produced at a rate of 1,103 BOPD gross (552 BOPD net) of oil at 33.5° API and with a 12% water cut (completion fluid and formation water). The production test utilized running the ESP at 30 Hz, the lowest setting on the pump. In addition, a 28/128 choke was inserted to efficiently manage the reservoir. Water cut decreased throughout completion testing. The CN-1 well is currently on production, producing from the C7 formation at 1,100 BOPD gross (550 BOPD net). The testing results indicate the well is capable of higher rates and the ultimate flow rate will be determined in the first few weeks of production.
Initial production results are not necessarily indicative of long-term performance or ultimate recovery.
