Invictus Energy Signs SLB for Musuma-1 Well as November Spud Stays on Track
Key Takeaways
- SLB (formerly Schlumberger) has been awarded the well services contract for Invictus Energy's Musuma-1 exploration well, with the November 2026 spud date formally confirmed.
- SLB previously worked on the Mukuyu-2 drilling campaign, bringing direct operational continuity to a frontier exploration site where contractor familiarity materially reduces execution risk.
- Three parallel workstreams are now running simultaneously: wellpad construction and civil works, Exalo Rig 202 maintenance, and SLB equipment preparation and mobilisation.
- Musuma-1 targets a material independent exploration play on the Eastern Margin of the Cabora Bassa Basin — a distinct target from the existing Mukuyu Gas Field discovery, representing additional upside rather than an extension of known resources.
- The Cabora Bassa Basin spans 360,000 hectares and is described as one of the last large untested frontier rift basins in onshore Africa, with the Mukuyu Gas Field already confirming a working petroleum system.
SLB secured as Musuma-1 well services partner — November spud on track
Invictus Energy has awarded a well services contract to SLB (formerly Schlumberger) for the Musuma-1 exploration well at the Cabora Bassa Project in Zimbabwe, with the November 2026 spud date confirmed. The award completes a critical component of the pre-drill campaign, with multiple operational workstreams now advancing in parallel ahead of drilling commencement.
Scott Macmillan, Managing Director
“Securing SLB completes another critical component of the Musuma-1 campaign and significantly advances operational readiness ahead of drilling.”
“With key drilling and well services now secured, and multiple workstreams progressing in parallel, Musuma-1 remains firmly on track to spud in November 2026 and we look forward to keeping shareholders updated as we continue to progress towards the commencement of this high-impact drilling campaign.”

What the SLB award means for Musuma-1
SLB has been selected to provide specialised services, technology, and operational resources for the Musuma-1 drilling campaign. The contract covers key services required to execute the drilling programme, with planning for equipment preparation, logistics, and mobilisation already underway.
Importantly, this is not a new relationship. SLB also worked on the Mukuyu-2 drilling campaign, bringing what Managing Director Scott Macmillan described as “valuable continuity from the successful Mukuyu-2 drilling campaign.” That continuity reduces the operational risk typically associated with onboarding a new contractor at a frontier exploration site.
Macmillan also highlighted that SLB brings “world-class technical expertise, equipment and operational capability” to the campaign. With the well services contract now in place, execution activity is described as accelerating across the project.
Three workstreams advancing simultaneously
The Musuma-1 campaign is not waiting on a single critical path — three parallel operational tracks are running right now:
- Musuma-1 wellpad construction and civil works — in progress, advancing ahead of rig mobilisation
- Exalo Rig 202 maintenance and readiness programme — commenced
- SLB well services equipment — entering preparation and mobilisation phase
Cultural ceremonies with local traditional leaders were conducted ahead of construction commencing, reflecting the company’s commitment to integrating cultural knowledge and respect into its operations.
Understanding what’s at stake at Musuma-1
For investors less familiar with oil and gas timelines, it helps to understand what a well spud actually means. Spudding is the commencement of drilling — it marks the physical start of the exploration well, not a discovery confirmation. What happens after the well is drilled determines whether hydrocarbons are encountered, and at what scale.
Musuma-1 is designed to test a material independent exploration target within the Eastern Margin play at the Cabora Bassa Basin. This is a distinct target from the existing Mukuyu Gas Field discovery, meaning it represents additional potential upside rather than an extension of what is already known.
Invictus’s asset portfolio within the Cabora Bassa Basin spans 360,000 hectares and the basin is described by the company as one of the last large untested frontier rift basins in onshore Africa. The basin already hosts the Mukuyu Gas Field discovery, alongside multiple basin margin prospects and other leads.
Cabora Bassa Basin frontier exploration has attracted attention precisely because the basin remains one of the few large, largely untested onshore rift systems in Africa, with the Mukuyu Gas Field discovery already establishing proof of a working petroleum system.
It is important to note that any prospective resource figures associated with Cabora Bassa Basin targets are unrisked estimates — they have not been adjusted for the chance of discovery or the chance of development. The company confirmed as at 3 September 2024 that there have been no material changes to the resource estimate since its last update. These figures represent potential upside if exploration is successful, not confirmed or contingent reserves. Investors should treat them accordingly.
What Musuma-1 does represent is a near-term, binary exploration catalyst. The outcome of this well will meaningfully inform the scale of the broader Eastern Margin opportunity.

Path to spud — key milestones ahead
Several workstreams must be completed between now and the November spud. The company has outlined the following steps:
- Completion of the Musuma-1 wellpad and associated civil works
- Completion of Rig 202 maintenance and readiness activities
- Preparation and mobilisation of SLB well services equipment
- Mobilisation of drilling materials, tubulars, and wellhead equipment
- Mobilisation of Rig 202 to the Musuma-1 wellsite
- Rig-up, commissioning, rig acceptance, and final pre-spud activities
The three primary parties executing these workstreams and their current status are summarised below:
| Party | Role | Status |
|---|---|---|
| SLB | Well services and drilling technology | Contract awarded; equipment preparation underway |
| Exalo S.A. | Rig 202 — drilling rig provider | Maintenance and readiness programme commenced |
| Invictus Energy | Operator — civil works and coordination | Wellpad construction in progress |
With key contracts in place and all three workstreams progressing simultaneously, November 2026 remains the confirmed spud window for Musuma-1. For IVZ shareholders, this well represents one of the more significant near-term exploration catalysts on the ASX — a high-impact frontier drill targeting a material independent play in one of Africa’s last large untested rift basins.
