Gas deposit discovered at Mukuyu2 well in Muzarabani
Australia Stock Exchange-listed oil and gas exploration company Invictus Energy has confirmed a significant gas discovery at its Mukuyu2 exploration well at the Cabora Bassa Project in Zimbabwe.

According to Invictus Managing Director Scott MacMillan, a total of four hydrocarbon samples were recovered to the surface from two separate zones in the Upper Angwa using the wireline formation testing tool. A further two formation water samples were recovered from the Basal Pebbly Arkoseformation.
He said gas and fluid properties from the recovered samples will be confirmed following laboratory testing once the sample bottles are dispatched from the rig for analysis and no additional fluid samples were captured to preserve the wireline formation sampling tool and remaining sample chambers for use in the interpreted Lower Angwa hydrocarbon-bearing zones where thicker sandstone units were penetrated in Mukuyu-2.
He said, significant additional gross sands were intersected within the Upper Angwa gas leg but are below the current net reservoir cut-off. These intervals may have better reservoir development elsewhere in the Mukuyu field and along with the refinement to the net pay criteria represent additional upside. Further appraisal and technical evaluation of log, core, seismic and well test data is required to determine the full extent of the resource size.
“We are delighted to declare a gas discovery from the Mukuyu-2 sidetrack well in the Upper Angwa formation.
“The discovery represents one of the most significant developments in the onshore Southern Africa oil and gas industry for decades.
“I’m extremely proud to be involved with the Invictus team and our partners in opening up one of the last untested rift basins. The perseverance and hard work of our dedicated team have paid off.
“The Company has delivered an exceptional result from the first two wells drilled in Mukuyu, which provides us with significant running room in our large portfolio of prospects and leads for further discoveries in our acreage in the Cabora Bassa basin.
“The Mukuyu-2 discovery, 7km away and 450 meters up-dip of the Mukuyu-1 well, which can subsequently be classified as a discovery, provides confirmation of the large potential of the Mukuyu field which has a structural closure of over 200km2.
“With additional hydrocarbon-bearing reservoirs ahead, the focus now is to complete the drilling and evaluation program and obtain further wireline data including fluid samples to declare an additional discovery from the Lower Angwa formation.”
Forward plan
The Exalo Rig 202 will drill ahead toward the sidetrack section Total Depth at approximately 3,400mMD through Lower Angwa reservoirs where multiple zones interpreted from logs to be hydrocarbon bearing were intersected in Mukuyu2.
Following the conclusion of the drilling of the 8 ½ inch hoe section, the sidetrack well will be logged including wireline formation testing and fluid sampling and final results provided.
