Aminex has confirmed that Rig 8000 is scheduled to arrive at the Ntorya-3 (NT-3) drilling location in mid-December 2026, with spudding of the well anticipated in late December, marking a major step forward in the development of the Ntorya gas field in southern Tanzania.
In an operational update released on 9 November, Aminex confirmed that the rig has been released by Maurel & Prom following its previous drilling assignment. Its arrival at Ntorya is now scheduled, with drilling expected to begin following rig assembly, commissioning, acceptance and mobilisation of the necessary drilling services.
The announcement provides shareholders with the clearest timetable yet for the next major Ntorya well, just six days after Aminex confirmed the signing of the drilling contract.
At the same time, the company has reaffirmed its target of achieving first gas from Ntorya-2 (NT-2) in late December, potentially bringing the commencement of commercial production and the drilling of a major new development well into the same month.
The confirmation that Rig 8000 has been released by Maurel & Prom is an important development in the preparations for NT-3.
The rig has already been operating in Tanzania, removing the need for international mobilisation of the main drilling unit. Its next scheduled destination is the NT-3 location, where arrival is expected in mid-December.
Following arrival, the rig will undergo assembly, commissioning and acceptance before drilling begins. The operator, ARA Petroleum Tanzania (APT), anticipates spudding the well in late December.
The drilling contract also provides flexibility for the wider Ntorya development. In addition to drilling NT-3, it includes options to undertake a workover of NT-1 or drill a separate well, together with options for two further wells.
These provisions could allow the operator to extend the drilling campaign beyond NT-3 as the development programme progresses.
NT-3 is a particularly significant well within the Ntorya development because it targets the central part of the interpreted gas-bearing reservoir system.
Aminex's latest seismic interpretation indicates that the well could encounter more than 200 metres of gross reservoir thickness, compared with approximately 51 metres encountered at NT-2.
A successful result would provide valuable information about the thickness, quality and productivity of the central reservoir, helping guide subsequent development drilling.
The well therefore represents more than an opportunity to add production capacity. It is an important test of the geological interpretation underpinning the wider Ntorya development programme.
With Rig 8000 now released, its arrival scheduled and a late-December spud anticipated, the programme is moving towards that important test.
The latest announcement also confirms substantial progress on the infrastructure required to receive Rig 8000.
Construction of the NT-3 well pad is approximately 60% complete, while the access roads are 80% complete. Completion and formal site handover are targeted for 15 December, aligning with the scheduled arrival of the rig.
Preparation of the rig base camp began on 20 September, with handover expected later in November.
These figures provide official confirmation of the construction activity visible in recent satellite imagery examined by AminexInvestors.com.
The cleared drilling location, developing access routes and associated construction areas form part of the preparations for the forthcoming drilling campaign.
Alongside the approaching NT-3 drilling campaign, Aminex has reaffirmed its objective of bringing NT-2 into production before the end of December.
Wellhead maintenance at NT-2 has now been completed, with no major findings reported.
The next operation will involve removing the bridge plugs, with the necessary equipment awaiting delivery and the work scheduled for late November.
Testing is expected to commence in December, subject to finalisation of the gas processing unit contract and timely mobilisation of the equipment.
Production into the Ntorya-Madimba pipeline remains targeted for late December.
For Aminex, which retains a 25% carried interest in the Ruvuma PSA, the commencement of gas production will represent the transition from exploration and development towards commercial operations.
The Tanzania Petroleum Development Corporation (TPDC) has confirmed that the Ntorya-Madimba pipeline remains scheduled for completion in December.
The pipeline will transport gas from Ntorya to the Madimba Gas Processing Plant, connecting the field with Tanzania's established natural gas infrastructure.
Its completion is being coordinated with the planned testing and commencement of production from NT-2.
Meanwhile, work at NT-1 is expected to resume in late November following delivery of replacement valves. Wellhead maintenance will be followed by slickline operations, the results of which will determine whether further intervention, potentially including a rig-operated workover, is required.
The latest RNS brings together two major developments that shareholders have been awaiting for years.
Rig 8000 is scheduled to arrive at NT-3 in mid-December, with the well expected to spud before the end of the month. At the same time, NT-2 is approaching its first commercial gas production.
The additional options within the drilling contract also provide a potential route towards a broader drilling campaign as the field moves into its next development phase.
Aminex Executive Chairman Charles Santos welcomed the latest operational progress, emphasising Ntorya's potential contribution to Tanzania's growing demand for natural gas and reaffirming the company's commitment to delivering first gas in December.
For shareholders and prospective investors, the significance is clear. Ntorya is approaching the point at which commercial gas production and a new drilling campaign could advance together.
After years of preparation, December 2026 is shaping up to be one of the most consequential months in Aminex's development history.
