Luiperd-1X test shows high condensate in Block 11B/12B

Total SE and partners proved high condensate yield and excellent reservoir connectivity during a drill stem test of Luiperd-1X in Outeniqua basin, South Africa, Africa Energy said Corp. said Dec. 7. The well is the second major discovery on Block 11B/12B, 175 km offshore and covering an area of about 19,000 sq km with water depths of 200-1,800 m.

The well intersected 85 m gross sand of which 73 m is net good quality pay in the main target interval and thicker than expected. The well reached total depth of 3,400 m on Oct. 12, 2020, when the drill stem testing program was initiated.

The well was opened to flow on Nov. 1, 2020. After several tests at different choke settings, the well reached a maximum constrained flowrate through a 58/64-in. choke of 33 MMcfd natural gas and 4,320 b/d condensate, an aggregate of about 9,820 boe/d. The choke configuration could not be increased due to surface equipment limitations. Absolute open flow (AOF) potential of the well is expected to be significantly higher than restricted test rates.

The Paddavissie Fairway in the southwest corner of the block now includes both the Brulpadda and Luiperd discoveries, confirming the prolific petroleum system, Africa Energy said. The original five submarine fan prospects in the fairway all have direct hydrocarbon indicators recorded on both 2D and 3D seismic data and intersected in the wells, significantly de-risking future exploration.

Total is operator of the block with 45% interest with partners Qatar Petroleum (25%) and CNRI (20%), and Main Street 1549 Proprietary Ltd. (10%). Africa Energy holds 4.9% effective interest in exploration rights for the block as it owns 49% of Main Street 1549 Proprietary Ltd.
