The company has concluded a wireline evaluation programme that was being conducted across the entire 8½” hole section at the wellsite. According to the preliminary formation evaluation of the wireline logging data including gamma ray, resistivity, density and neutron tools, there lie numerous potential gas bearing zones coincident with intervals which displayed elevated gas shows during drilling.

Positive log analysis

Invictus considers that the preliminary logging analysis from the wireline programme in the 8½” hole section at Mukuyu-1 wellsite as encouraging. As per the announcement, the ongoing log analysis is expected to be finalised after the wireline formation testing.

Standpoint for future

Invictus is preparing the Exalo Rig 202 for drilling at Muluyu-1 wellsite for testing the deeper potential of the remaining Upper Angwa and potentially Lower Angwa formations.

The company is planning to run another wireline logging evaluation suite, including wireline formation testing, seeking in-depth geological information. This will also confirm the presence of moveable hydrocarbons.

IVZ expects to complete the remaining drilling and logging operations in about five to seven days, depending upon the borehole conditions.
