Highlights
- Invictus Energy has concluded mudgas analysis of additional 22 samples that were obtained from the Mukuyu-1 / ST-1 well at its Cabora Project.
- The results confirm the presence of helium, wet gas and condensate, and light oil in Mukuyu-1.
- Light oil and gas condensate has also been detected in sidewall core analysis, suggests the results.
Australian oil & gas exploration company Invictus Energy Limited (ASX: IVZ) has concluded analysis of additional 22 mudgas samples that were acquired from the Mukuyu-1 / ST-1 well at its Cabora Bassa Project in Zimbabwe.
The most recent results have reaffirmed that light oil, gas-condensate, and helium, are present at the site. The geochemical samples were collected from the Pebbly Arkose and Upper Angwa formations. They have demonstrated that dryness has been increasing with depth.
Details of the findings
As per the latest results, consistent, high-quality natural gas is present with low inert content. It indicates that samples consist of <1% carbon dioxide, which needs least processing.
The presence of light oil or gas condensate has also been demonstrated in the results of a whole extract analysis of fluids collected from a sidewall core of Mukuyu-1 in a reservoir interval in the Upper Angwa.
These findings are in line with the analysis report from the nearest mudgas sample obtained from the same reservoir interval reflecting elevated gas shows noted during drill campaign at Mukuyu-1 and up to 135 times above background gas baseline and fluorescence.
Also, organic shales are present in rock samples from the Upper Angwa, within the maturity window for the generation and expulsion of volatile oil, condensate, and wet gas. Its total organic content has been estimated to be up to 10%.
The results are in line with mudgas composition as well as isotope results. Further basin modelling is in progress to analyse the potential of this organic matter to produce hydrocarbons.
