Impact Oil & Gas, a privately-owned, Africa-focused, exploration company, has provided an operational update, following the successful completion of drilling and DST operations at the Tamboti-1X exploration well and spudding of the Marula-1X exploration in Block 2913B (PEL 56), offshore Namibia.
Tamboti-1X was safely and successfully drilled to a total depth of 6450mMD on Block 2913B, approximately 12km northeast of the Mangetti-1X well and approximately 25km north-northwest of the Venus-2A well, using the Deepsea Mira semi-submersible drilling rig.
- Black oil was encountered within within 85m of net reservoir of lower quality Upper Cretaceous sandstones, belonging to the Mangetti fan system.
- A DST programme has now been concluded at the Tamboti-1X location, and results from the acquired log, core and DST data are currently under analysis.
On 3 February, the Deepsea Mira spud the Marula-1X exploration well within the southern part of Block 2913B. This well will target Albian-aged sandstones, within the Marula fan complex and has the potential to unlock further exploration targets across the south, which is an area lying at the heart of the prolific Kudu source-rock kitchen. At the end of 2025, the Deepsea Mira is expected to drill the Olympe prospect, targeting Albian sands within a structural closure on Block 2912.
The Joint Venture is continuing to progress the proposed development of the Venus Field, with development studies ongoing. Since the 2022 Venus-1X discovery well, three further wells have successfully penetrated the Venus Field, and four drill stem tests have been successfully carried out. The Venus Field is expected to be the first development in Block 2913B, producing 150kb/d of ~45° API oil, with final investment decision expected by the first half of 2026
Siraj Ahmed, Chief Executive Officer of Impact commented:
'2025 has commenced with an exciting programme of activities on Blocks 2912 and 2913B, with exploration continuing to prove up resources, whilst the Joint Venture rapidly advances towards the first development – the Venus Field – in our Namibia portfolio.
'With further analysis of the Tamboti-1X results underway, the outcome of this well, within the northern region of Block 2913B, highlights the potential of Namibia’s deep offshore play.
'In the South, the joint venture has spud the Marula-1X well, our first well in the Marula fan complex, an area lying at the heart of the prolific Kudu source rock kitchen, which we hope will unlock further exploration targets.'
