Southern Africa wildcatter Invictus Energy has announced plans to drill a second well on its Mukuyu structure in Muzarabani.
Invictus Energy Managing Director Scott Macmillan said preparations for the Mukuyu-2 appraisal well have commenced. He said:
Preparations for the Mukuyu-2 appraisal well have commenced, with drilling currently targeted to commence in early Q3.
We will take the learnings from the successful Mukuyu-1/ST1 well to optimise the well design for the drilling conditions encountered and the ability to evaluate multiple hydrocarbon bearing intervals.
Post-well analysis of Mukuyu-1 indicates potential for significant gas columns in the Pebbly Arkose and Upper Angwa formations, based on significantly elevated pressures in interpreted gas-bearing sands above normal hydrostatic gradient.
Preliminary processing of the side wall cores obtained in the Mukuyu-1 well has also provided further encouragement for the Company.
Additional fluorescence observed in the upper Pebbly Arkose reservoir sections has increased the gross interval with hydrocarbon charge throughout the Pebbly Arkose and Upper Angwa to 1,500 metres and substantially expands the play interval in the Cabora Bassa Basin.
Following success at Mukuyu-1/ST1, which confirmed a working hydrocarbon system in the basin, we have received industry interest to participate in the Cabora Bassa Project and the Company is considering a range of options to manage forward exploration, appraisal and development programs
We are also planning an infill 2D seismic survey in EPO 1848/49 to mature multiple leads into drillable prospects along trend from Mukuyu, and the highly prospective Basin Margin play.
Macmillan and the entire Board are expected to spend time on the ground in Zimbabwe early next month.
Invictus said on the back of positive results from Mukuyu-1/ST1, it has received interest from industry partners to participate in the Cabora Bassa Project. The company said in an announcement:
The well design for Mukuyu-2 will incorporate valuable experience gained from the drilling of the successful Mukuyu-1/ST1 exploration well to improve drilling efficiency and lowering operational risks.
The appraisal well will also be designed to test the deeper potential in the remaining Upper Angwa formation, which was not encountered in the Mukuyu-1/ST1 campaign due to it being thicker than pre-drill estimates.
The Mukuyu-1/ST1 well encountered gas pay to total depth, interpreted from wireline logs and fluorescence in multiple reservoirs throughout the 900-metre interval penetrated.
This additional prospectivity in the Upper Angwa and the undrilled Lower Angwa target provides further up-side potential at Mukuyu-2.
The Mukuyu-2 well design will allow for flow testing to confirm reservoir deliverability and connectivity following a successful discovery.
The tendering process has commenced for minor additional long leads and well services and the completion of this process will help further refine the timing of the spud date for Mukuyu-2.
