document: Early November 2017, Tullow Oil plc completed the drilling of the appraisal well Amosing-7 in the Block 10BB. Amosing -7 was the last well of the 2017 drilling programme. Therefore the Marriott-46 rig was demobilised. The well encountered 25 m of net oil and gas pay. No further information was disclosed.  Tullow Oil operates blocks 10BB with a 50% interest partnered with Africa Oil with 25% and Maersk Oil & Gas with 25%. Gross unrisked oil resources (2C) South Lokichar Basin are estimated at 754 MMbbl. Tullow and its partners signed the Early Oil Pilot Scheme (EOPS) agreement to transport oil from the South Lokichar fields to Mombasa on 14 March 2017. The EOPS represents an immediate step on the road to full commercialization of the oil resources and it will be followed by a full-scale Field Development Plan.  In mid-March 2017, Tullow Oil completed the appraisal well Amosing 6 that encountered 35 meters of net gas and oil pay. The well was drilled near a bounding fault and was spudded early February 2017 with the âPR Marriot 46â land rig. The Amosing 6 was the second well in a four-well drilling campaign in the South Lokichar Basin (Blocks 10BB and 13T), which started in December 2016 and led to the Erut 1 oil discovery in January 2017. The Amosing field has recoverable resources estimated at 151.1 MMbbl of oil, whereas the Ngamia field has 296.7 MMbbl of oil.
