Sonangol flow tests first non-associated gas reservoir in Angola
Key Highlights
- Sonangol drilled and tested an appraisal well in Benguela basin, offshore Angola.
- The well can potentially produce more than 100 MMscfd.
- This is Angola's first full flow test in a non-associated gas reservoir.
Sonangol Exploração & Produção completed drilling and testing of the Katambi-2 appraisal well in Block 24 of Benguela basin, offshore Angola, the National Oil, Gas, and Biofuels Agency (ANPG) said Aug. 6.
Drilled 1.3 km from the Katambi-1 well, the Katambi-2 well crossed two production intervals, with about 331 m of total thickness, confirming the existence of good quality reservoirs. The intervals have 9-12% average porosity and good permeability, higher than that recorded in the Katambi-1 well drilled in 2014-2015.
Initial tests recorded a stabilized production of 41 MMscfd of gas and 1,160 b/d condensate without water or H2S, reinforcing the economic viability of the development of the discovery and its potential contribution to the optimization of national production. This is the first full flow test carried out in a non-associated gas reservoir in Angola.
A preliminary assessment of the test results indicated that the well has the potential to produce more than 100 MMscfd.
Block 24 lies 370 km southwest of Luanda. Sonagol is operator of the block.
