Aminex is pleased to announce that the Ntorya-2 appraisal well has been successfully drilled to a depth of approximately 2750 m. At 2596 m drilling depth the well encountered a gross gas bearing reservoir unit of approximately 51 m.
Preliminary petrophysical analysis of the Logging While Drilling (LWD) logs indicates a porous and hydrocarbon bearing reservoir with a potential net pay of between 25 and 30 m. Drilling of the reservoir section was associated with significant gas influxes and higher than expected pressures. The result is well ahead of the Company’s pre-drill expectations.
The well is currently being deepened to a total depth of approximately 2780 m, prior to a wireline logging programme being run, to allow for the setting of a 7 in. liner below the reservoir interval. Detailed petrophysical analysis will be conducted on both the LWD and wireline logs. Preparations are currently underway for a comprehensive well testing programme and the Company expects to have results of the flow-testing and ongoing petrophysical analysis by late February.
Ntorya-2 also encountered traces of oil in the gross reservoir interval and the Company is now evaluating the implications of this positive development through an updated basin model.
The well was spudded in the onshore Ruvuma Basin of Tanzania (Mtwara Licence: Aminex 75% and operator) on 21 December 2016 in order to appraise further the Ntorya Appraisal Area. Ntorya-1 had a net pay of 3.5 m and flow-tested at 20 million ft3/d, with 139 bbls of associated condensate. The Ntorya field is approximately 40 km from the Madimba gas processing plant, which receives gas into the National Gas Pipeline system.
Depending on the results of the well test, the Company intends to apply for a 25-year development licence over the Ntorya Appraisal Area.
Jay Bhattacherjee, CEO of Aminex said:
“We are delighted with the progress of the Ntorya-2 appraisal well, which is ahead of our expectations. The reservoir is both thick and high quality. Aminex looks forward to providing the results of the flowtesting which will enable the joint venture to consider its options for development of the Ntorya field.”
