Aminex is pleased to confirm that the Ntorya-2 appraisal well has now been successfully tested and is being suspended for future production. Ntorya-2 was drilled in the onshore Ruvuma Basin of southern Tanzania, on the Mtwara Licence (Aminex 75%, operator) which is governed by the Ruvuma Production Sharing Agreement. The well flowed dry, high quality gas at average stable rate of 2,833 barrels of oil equivalent per day. No formation water was produced during the test, leading Aminex to conclude that the Ntorya-1 and Ntorya-2 area contains a significant volume of gas in place. Due to strong gas influxes encountered while drilling through the reservoir section, and in order to preserve the safety of the well operations, Aminex was required to increase drilling mud weights in order to maintain well control and operate within safety parameters. The higher than planned mud weights resulted in reservoir invasion which tempered overall test performance. Aminex will now complete a full analysis of all technical data prior to applying for a 25-year development licence over the Ntorya appraisal area. (Source and image: Aminex / Ntorya-2 well test)
