In March 2019, it was reported that Delonex Energy Ltd (Delonex) was looking for a partner to share the exploration risk in the Block 12A. The company has hired PVE Consulting Ltd to help them with the farm-out process. Interested parties can contact PVE Consulting to obtain the flyer. Delonex operates the licence with a 60% interest. Partner is Tullow that holds the remaining 40%.   Block 12A covers 15,390 sq km in the underexplored South Kerio and Suguta-Magadi troughs (also referred to as Kerio Valley Basin by Tullow) in the eastern branch of the East African Rift System (EARS). It contains the Cheptuket-1 new field wildcat well (P&A in March 2016 with good oil shows across an interval of over 700 m). Tullow believed that the Cheptuket-1 results were very encouraging as they indicated a significant oil generation, despite the non-commercial quantities.  In August 2018 Delonex completed a 450 km 2D seismic survey over the block. The survey started in early March 2018 with a BGP crew and covered the Baringo, Elgeyo, Marakwet and West Pokot counties. The initial plan was to acquire some 528 km of 2D data.   The aim of the 2D seismic survey was to complement the previously acquired FTG survey (2016) and the 2D seismic data acquired in 2014. It will optimize the location of future exploration wells. According to Tullow, seismic images obtained so far in the South Kerio troughs are more difficult to interpret compared to other sub-basins within the EARS, possibly due to reflection noise from older formations.  Background Information  Block 12A - License history  Block 12A was originally awarded to Platform Resources Inc., a wholly owned subsidiary of Alberta Oilsands Inc., in late 2008. In August 2010, Africa Oil Corp. took over the tract with 100% interest. Tullow Oil and Marathon Oil Corp entered the permit in February 2011 and June 2012, respectively.  Delonex took over former partner Marathonâs 15% stake and bought an additional 25% from Tullow in November 2015. In early 2016, Tullow Oil plc relinquished a small portion of Block 12A, which was converted into Block 12AA.  Following Africa Oil announcement that it is withdrawing from the licence, Delonex took over Africa Oil 20% interest. Following the deal, Delonex ended up having the operatorship and 60% interest in the block.  Exploration activity in Block 12A  Tullow completed a 520 sq km 2D survey over Block 12A between April 2013 and February 2014, with BGP as contractor.  Tullow spudded the Cheptuket-1 new field wildcat on 28 December 2015. The Cheptuket-1 well (originally planned as Lekep 1) was meant to test a basin bounding structural closure in a similar structural setting to that of the Ngamia and Amosing discoveries in neighbouring Block 13T. The Cheptuket prospect had mean prospective reserves estimate of 35 MMbbl of oil. The well targeted the Lower Miocene Lokone sandstone reservoirs. According to Tullow, there were excellent oil-prone source rocks identified in outcrops (Type I lacustrine, TOC > 3%, early oil-generation window).   Drilling operations were completed around 16 February 2016 and were followed by extensive logging. Cheptuket 1 found good oil shows across an interval of over 700 m in both cutting and rotary sidewall cores. The well was drilled to a TD of 3,803 m with the âPR Marriot 46â land rig, which was released around 4 March 2016.
