It will be a follow-up to the successful wells of the Ntorya project, with CH-1 located up-dip from both the Ntorya-1 and Ntorya-2 wells.
The well is expected to delineate the Ntorya gas field in a significantly thicker section of the reservoir system and is also intended to evaluate a deeper exploration target.
Success is expected to lead to production into the existing Madimba gas processing plant, before being integrated into a wider field development.
A tendering process is now underway to hire a rig for the CH-1 programme.
"The company continues to progress the completion of the proposed farm-out transaction while driving forward operations over its key assets at Ruvuma and Kiliwani North," said Jay Bhattacherjee, Aminex chief executive.
Additionally, the company noted that pressure in the Kiliwani North-1 well has built up sufficiently and work continues to stimulate production as soon as possible.
