Testing Results from the Ubaque in the CN-1
Arrow Exploration, the high-growth operator with a portfolio of assets across key Colombian hydrocarbon basins, has provided an update on the Carrizales Norte-1 well ('CN-1'), an exploration well on the Tapir Block in the Llanos Basin of Colombia.
CN-1
The CN-1 well was spud on May 1, 2023 and reached target depth on May 11, 2023. CN-1 targeted a three-way fault bounded structure with multiple high-quality reservoir objectives on the Tapir Block in the Llanos Basin of Colombia. The well was drilled to a total measured depth of 9,190 feet (8,511 feet true vertical depth) and encountered 148 feet of cumulative net oil pay (128 feet TVD).
Arrow has completed the first test on the CN-1 well in the Ubaque formation which has approx. 58 feet of net oil pay. The pay zone is a clean sandstone exhibiting consistent 30% porosity and high resistivities. A submersible pump has been inserted in the well after perforating.
Specific data for the production test on the Ubaque formation were as follows:
- The production test was run over a 58-hour period.
- The well was tested at three different flow rates to evaluate productivity and to plan for water cut management.
- The first flow period was held for 23 hours and showed an average oil rate of 491 bopd gross.
- The second flow period was for 18 hours and showed an average oil rate of 861 bopd gross, and,
- The third flow period was held for 17 hours and showed an average oil rate of 1134 bopd.
- Oil production tested at a peak rate of 1,222 bopd, and a final stabilized rate of 1,134 bopd
In the final 24 hours of the test, CN-1 produced at a rate of 1,134 bopd gross (567 bopd net) of oil at 13.5 API and with a 28.3 % water cut (completion fluid). Water cut has been decreasing throughout completion testing. Additional tests of the Gacheta and C7 formations will proceed over the coming weeks, with production forecast to commence in the second half of June 2023. The Carrizales Norte-2 (CN-2) well will be drilled immediately upon the CN-1 well being brought on-stream.
Initial production results are not necessarily indicative of long-term performance or ultimate recovery.
Marshall Abbott, CEO of Arrow commented:
'The Carrizales Norte-1 discovery and the Ubaque test are extremely important and material events for Arrow. The Ubaque test – the first on the Carrizales Norte field - shows that oil from the formation can be produced at high rates using conventional means. The test is further evidence of the potential of the Tapir block in the prolific Llanos Basin.
'After a brief flow and pressure build-up on the Ubaque, Arrow plans to completion test additional pay zones in the Gacheta and C7 reservoirs over the coming weeks and then make a decision on which zone to bring on production initially.
'Our expectation is that the Carrizales Norte wells will be quick to payout in the current oil price environment with triple digit IRRs, providing positive cashflow for the Company. This is a very exciting time for Arrow, and we look forward to providing further updates on our progress.'
