Independent upstream oil and gas company Invictus Energy (ASX:IVZ) reports it has encountered multiple potential gas bearing zones following a preliminary wireline program at its 80% SG 4571 licence in Zimbabwe’s Cabora Bassa Basin.
The recently completed preliminary wireline program was conducted across the entire current 8 (½) hole section within the Mukuyu-1 well and indicates the presence of multiple potential gas bearing zones coincident with intervals that demonstrated elevated gas during drilling.
Log analysis of the wireline program is subject to further calibration using core and fluid samples taken from the well using a wireline formation testing tool, which is now en-route to the well-site.
It is reported that log analysis is ongoing and will be finalised post wireline formation testing, which will acquire formation pressure and samples from zones of interest.
Commenting on the potential gas bearing zones, Invictus Energy Managing Director, Scott Macmillan said: “Preliminary logging analysis from this early stage of the wireline program in the current 8 (½) hole section has been encouraging, indicating multiple potential gas bearing zones.
However, the presence of moveable hydrocarbons will be determined following the wireline formation testing program, which will be run following the arrival of the wireline formation testing tool at the wellsite.
“Preliminary logging analysis … has been encouraging, indicating multiple potential gas bearing zones.”
In the interim we have elected to drill ahead to test the deeper potential of the remaining Upper Angwa and Lower Angwa formations which will also provide us with valuable geological and geophysical information for future wells in the basin.
We anticipate the remaining activities will require a further 5-7 days to complete following which final well results will be provided.”
The company also notes the Exalo Rig 202, which is leading the ongoing drilling campaign within the Mukuyu-1 well, is preparing to drill ahead to about 3,800m to test deeper potential within the remaining Upper/Lower Angwa formations.
Invictus Energy is a sub-Saharan African focused oil and gas company that is currently opening one of the last untested large frontier rift basins, the Cabora Bassa Basin in northern Zimbabwe. The company currently owns the SG 4571 asset, which covers the most prospective portion of the Cabora Bassa Basin and currently covers a total land holding of about 250,000 acres. The asset is estimated to contain 20Tcf and 845 million barrels of conventional gas condensate.
Invictus Energy announces the remaining drilling and logging operations are expected to be completed within a further 5-7 days, subject to borehole condition.
