Solo has announced that the site preparations for the Ntorya-2 appraisal well have now been completed and that mobilisation of the Caroil#2 rig from the Ntorya-1 wellsite is now underway.
The Ntorya-2 pad is located approximately 1.5 km to the southwest of the Ntorya-1 well. The rig and associated equipment are being transported to the new site, will be rigged up and tested, and will then undergo any maintenance required before being taken on under the contract reported on 23 September 2016. The majority of other well services have also now been contracted. Solo therefore estimates that the Ntorya-2 appraisal well is likely to spud in December 2016.
Solo holds a 25% interest in the Ruvuma Petroleum Sharing Agreement (Ruvuma PSA) which contains the Ntorya gas condensate discovery made in 2012 with the Ntorya-1 well which was tested at a rate of 20.1 million ft3/d and 139 bpd of condensate from a 3.5 m interval at the top of a 20 m Cretaceous sandstone pay zone at a depth of approximately 2600 ft.
The Ntorya-1 well has been credited in an independent report by Senergy (GB) Limited with gross 153 billion ft3 of gas in place, of which 70 bcf are considered gross best estimate contingent resources. A further gross best estimate of undiscovered gas in place of over 1 trillion ft3 is attributed to the Ntorya Prospect as a whole and is the target of the Ntorya-2 well which is being drilled updip and in a thicker part of the sand body interpreted on the 2014 seismic data acquired to facilitate appraisal.
The Ntorya discovery lies just 20 kms from the 36 in. Mtwara to Dar es Salaam gas pipeline which was commissioned in late 2015 and is transporting produced gas from various fields, including the Kiliwani North Field where Solo holds a 7.125% interest, to gas markets in the north of Tanzania.
Neil Ritson, Solo's Chairman, commented;
"Advancing the Ntorya appraisal and its commercialisation is now a key objective for Solo and we are pleased that rig mobilisation is now underway. The discovery of gas in high quality Cretaceous sandstone reservoirs in the onshore portion of the Ruvuma Basin represents very significant value and we look forward to confirmation of the spud date in due course."
The Ruvuma PSA is operated by Aminex plc who hold the remaining 75% working interest.
