Invictus Energy Ltd. confirmed a gas-condensate discovery at Mukuyu in license SG 4571, Cabora Bassa basin, Zimbabwe.
The Mukuyu-2 well was sidetracked in December 2023 and discovered gas in the Upper and Lower Angwa reservoirs (OGJ Online, Dec. 7, 2023). Compositional analysis confirms high quality natural gas containing minimal impurities (less than 2% CO2 content and no H2S) which will require minimal processing to prepare for sale. Condensate gas ratios (CGR) from Mukuyu-2 samples are estimated between 14-22 bbls/MMscf with a 50-60° condensate API gravity. Likewise, Mukuyu-1 mudgas analysis confirmed light oil and gas condensate yields of 30-135 bbls/MMscf with minimal impurities.
Preliminary analysis from Mukuyu-2 and results from Mukuyu-1 are consistent with Invictus’ geological modelling which shows increasing liquid hydrocarbon content in the south of Mukuyu towards the Basin Margin (where multiple drill-ready prospects have been mapped) and increasing dry gas contribution from the deeper kitchen and higher maturity source rock north of the Mukuyu structure. Consistent with the Mukuyu-1 results, gas samples from Mukuyu-2 show a general increasing dryness (lower liquid hydrocarbon-condensate yield) with depth.
Additional downhole reservoir fluid and mudgas samples are being processed. Further analysis is ongoing which will be integrated into the geological model across Mukuyu field and the wider portfolio of prospects and leads in the license area.
Invictus is operator with 80% interest.
