Invictus Energy reaffirms gas-condensate discovery

Invictus Energy Limited has confirmed a rich gas-condensate discovery in Mukuyu and presence of light oil following an additional downhole fluid sample analysis.

The compositional analysis confirms high quality natural gas containing minimal impurities (less than 2% CO2 and nil H2S) which will require minimal processing to prepare for sale to customers.

Invictus Energy Limited managing director, Scott Macmillan has expressed his excitement over the company’s continued success.

“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 law 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 the 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 analysis 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 auger 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 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,” he said.

In a statement, Invictus said the presence of migrated hydrocarbons from a structure is extremely positive for the overall hydrocarbon charge, migration and reservoir connectivity in Mukuyu.

“Preliminary results suggest the source of the hydrocarbon recovered from Mukuyu-2 is very similar to the reservoir extract from Mukuyu-1, which indicated both gas and liquid-prone source rocks are present over the sizable fetch area within and beyond the Mukuyu structure. These results further support the company’s geological modelling showing multiple hydrocarbon charge events from multiple source rocks with increasing liquid hydrocarbon content south towards Basin Margin and increasing dry gas contribution from deeper kitchen and higher maturity source rocks to the north of Mukuyu structure.

“The results to date provide significant insight into the Cabora Bassa basin geological history and confirmation of the accurate modelling conducted by the company in the lead up to the Mukuyu discovery,” reads the statement.
