Invictus’ decision to acquire detailed 2D seismic over its Cabora Bassa project is paying off with preliminary processing already returning encouraging results.

The work on selected lines by contractor EarthSignal has already resulted in strong amplitude anomalies, which indicate that hydrocarbons may be present, in shallow sections of the target Muzarabani structure and basin margin fault.

Importantly, amplitude anomalies are located where hydrocarbon bearing traps, geological structures that prevent oil and gas from migrating upwards, are typically expected to be located.

Invictus Energy (ASX:IVZ) noted that all seismic data has been delivered from the field and full processing has commenced.

It added that the previous survey acquired by Mobil will be reprocessed in conjunction with its CB21 survey to integrate the legacy dataset and apply insights to the entire Cabora Bassa Basin.

The preliminary results also highlighted potential “flat spots” that could indicate hydrocarbon content.

Managing director Scott Macmillan said the initial processing has produced high quality data revealing a variety of structural and stratigraphic features that provide for a target rich environment for the upcoming drilling program.

“The early indications from the preliminary seismic processing are very encouraging and particularly the strong amplitude anomalies observed in the Muzarabani structure and along the basin margin fault,” he added.

“While we look forward to the final processed products and interpretation of the entire CB21 Survey which will also enable better characterisation of the primary Upper Angwa target in the Muzarabani prospect, these initial results are encouraging as we progress with the selection of optimal drilling locations for the upcoming drilling campaign scheduled for 1H 2022.”

Cabora Bassa

The 2D seismic survey at Cabora Bassa, which has been independently assessed to host prospective resources of about 9.25 trillion cubic feet of gas and 294 million barrels of condensate, is expected to help refine the location and path of the planned Mzarabani-1 gas exploration well.

Previous work had defined five stacked targets at the prospect, all of which will be tested by the same well.

There is big demand for gas in southern Africa with multiple large scale power generators, miners, chemical processing and industrial customers.

This is highlighted by South Africa’s state-owned Central Energy Fund requesting recently for information to assess the potential to import LNG to help fill the energy gap as coal-fired power plants to provide 20% of the country’s electrical supply are retired.
