Invictus Energy positive sample results reinforce Zimbabwe gas discovery
Invictus Energy has reinforced the confirmation of a rich gas-condensate discovery in the Mukuyu field, following positive results from further downhole reservoir fluid sample analysis.
The analysis showed high quality natural gas with minimal impurities, requiring minimal processing for sale. Samples also showed condensate gas ratios between 10-25 barrels per million standard cubic foot of gas, with an API gravity of 50-60 degrees.
Invictus Managing Director, Scott Macmillan, said the results were “exceptionally positive” and exceeded expectations. He said the high-quality liquids-rich gas would allow the company to target a low-cost development with minimal processing of the gas at surface.
“We are extremely pleased with the results from the additional downhole reservoir fluid sample analysis which confirms a substantial rich gas-condensate discovery at Mukuyu and set up the company for continued success in Mukuyu and the Upper and Lower Angwa geological trend.
“The samples demonstrate a consistent, high-quality natural gas composition, with low inert content, less than 2% CO₂ and nil H₂S, which will require minimal processing for sale.
“In addition to gas-condensate proven in the Upper and Lower Angwa formations, we have further evidence of the presence of light oil in the Upper Angwa and potentially Dande formation from multiple hydrocarbon source rocks and charge events.
“The hydrocarbons present in the Mukuyu gas-condensate field appear from initial analyses to have been generated and expelled from both local source rock intervals within the massive Mukuyu structure and also migrated from other source rock rich areas off-structure.
“These results augur well for the presence of hydrocarbons in the prospects and leads in the remainder of the Company’s acreage which has been de-risked by the Mukuyu gas-condensate discovery.
“The gas-condensate composition results are exceptionally positive and exceeded our pre-drill expectations with high-quality, liquids-rich gas with low inerts found in both Mukuyu wells which will allow us to target a low-cost early monetisation development with minimal processing of the gas at surface from the Mukuyu field.”
The analysis also showed evidence of light oil in the Upper Angwa and Dande formations. Further analysis is being done to confirm this, but the results suggest the potential for light oil from more oil-prone source rock in Mukuyu.
Overall, the results provide significant insight into the Cabora Bassa basin geological history and confirmation of the accurate modelling conducted by Invictus. The Company says this will be used to select future exploration well locations.
