Zimbabwe hits new oil, gas drilling milestone

Invictus Energy has begun moving its Exalo Rig 202 to the Musuma-1 exploration site in Zimbabwe's Cabora Bassa Basin, marking a major step towards drilling a new oil and gas exploration well scheduled for November 2026.

The relocation signals a shift from site preparation to the final stages of drilling readiness at the high-impact prospect on the eastern margin of the basin.

The rig, owned and operated by Polish contractor Exalo Drilling SA, previously drilled the Mukuyu-1 exploration well in 2022 and the Mukuyu-2 appraisal well in 2023. The campaigns established a significant gas and gas-condensate discovery, with initial estimated volumes of approximately 1.3 trillion cubic feet of gas equivalent, or about 230 million barrels of oil equivalent, across the Upper and Lower Angwa formations.

The move to Musuma-1 follows the completion and acceptance of the wellpad, civil works, drainage systems and access roads. Crews are now undertaking rig-up operations, maintenance and other readiness activities before final acceptance of the rig.

Invictus managing director Scott Macmillan said the mobilisation marked another important milestone as the company advanced towards drilling its next exploration well.

"With the key drilling and well services contracts secured, supporting infrastructure completed, and the rig move now underway, preparations continue to advance towards drilling," Macmillan said.

He added that Musuma-1 offered an opportunity to test a new geological play beyond the existing Mukuyu discovery area.

The planned vertical exploration well targets a prospective gross mean unrisked resource estimated at 1.2 trillion cubic feet of natural gas and 73 million barrels of gas condensate.

However, these figures represent prospective resources rather than confirmed discoveries. The quantities that may ultimately be recoverable, and whether they can be produced commercially, will depend on the results of drilling and subsequent technical assessments.

A successful outcome at Musuma-1 could expand understanding of the petroleum system across Invictus's acreage and increase the resource potential of the wider Cabora Bassa Basin.

The project operates under a Petroleum Production Sharing Agreement signed between the Government of Zimbabwe and Geo Associates (Pvt) Ltd, the local subsidiary in which Invictus holds an 80% interest. The agreement establishes the framework governing the project's commercial and fiscal arrangements, including state participation through the Mutapa Investment Fund.

Despite the discovery at Mukuyu, commercial gas production has not yet begun in the Mbire and Muzarabani districts. Further appraisal, flow testing and development planning are required before the project can progress towards production.

Commercialisation would also require investment in gathering infrastructure, processing facilities and arrangements with customers. Potential applications include gas-fired electricity generation and supplying energy and industrial feedstocks to mining and manufacturing operations.

The project could offer significant economic opportunities if commercially viable resources are established and developed. These include attracting foreign investment, creating employment, improving local infrastructure and potentially reducing Zimbabwe's reliance on imported energy.

For now, attention is focused on completing the rig mobilisation and commencing drilling at Musuma-1 in November. The results will help determine whether Invictus can extend its discovery beyond Mukuyu and advance Zimbabwe's ambitions to develop a domestic oil and gas industry.
