Tullow Oil encountered up to 90metres net oil pay in several oil pools, after sidetracking the Amosing 2 well back to the Amosing 1 discovery well. The original hole had encountered 30metres net oil pay, before the sidetrack.
The Amosing-2 well in Kenya’s Block 10BB licence is the first appraisal well on the Amosing field discovered in January 2014, and was drilled from the Amosing-1 well pad. The well was deviated 1,350metres towards the northeast and down dip from the discovery well to calibrate the oil-water contacts of the several oil pools identified in Amosing-1. The Amosing-2 well encountered up to 30metres net oil pay. As planned, the well was then sidetracked back to some 400metres from the discovery well to provide additional insight into reservoir distribution in the area and for use in interference testing, planned to start later in 2014. “The Amosing-2A sidetrack encountered up to 90metres net oil pay in several oil pools”.
The Sakson PR5 rig drilled Amosing-2 to a final depth of 2,878metres and the Amosing-2A sidetrack to a final depth of 2,165metres. The rig will now be moved to explore the southern extent of the South Lokichar basin to drill the Ekosowan-1 well in September 2014, 11.9 km south east of the Amosing-1 well.
