Siccar Point spudded appraisal well 204/10a-5 on the Cambo discovery on 24 April 2018. The discovery is situated across licences P1028 and P1189. The company contracted the âWest Herculesâ rig for the operations. The appraisal well targeted the main reservoir. On 29 May 2018 the company completed its vertical well which encountered more than 100 ft oil column with a net pay of 58 ft. Logging operations confirmed a high quality multi-darcy reservoir with an API of 23 degrees. Siccar Point then kicked-off its first horizontal sidetrack 204/10a-5Z. On 5 June 2018 Siccar Point confirmed that it was cementing the casing prior to drilling out into the horizontal section. On 13 June 2018 it was reported that a second sidetrack, 204/10a-5Y had been kicked-off. The horizontal section was drilled for 1,612 ft and was tested for 10 days (which commenced on 3 August 2018). Testing operations indicated excellent reservoir productivity and sustained flow. A full evaluation of the test results will take place in the coming weeks to allow for further pressure build-up following the rigs departure.  Licence P1028 was awarded in the 19th Seaward Licensing round and comprises blocks 204/9a and 204/10a covering a total area of 178 sq km. P1189 was awarded in the 22nd Seaward Licensing Round and covers a total area of 60 sq km comprising blocks 204/4a and 204/5a. Cambo was discovered in 2002 by Amerada Hess with well 204/10-2. Five wells in total have been drilled on the structure to date. The plan for the appraisal well is to undertake an Extended Well Test (EWT) on the field. Cambo is a large basement high with sedimentary sequences draped over the top of the structure. It has an Hildasay reservoir and the field is thought to hold approximately 600 MMbo in place. The plan for the potential development is that it will be developed in two phases. Phase one involves a leased FPSO with seven producing wells and two water injectors and the plan is to produce approximately 87 MMbo and also some associated gas. Phase two details have not been defined to date. FID for the field is scheduled for the first half of 2019. Siccar believes that the Cambo area has material upside around areas of undrilled Hildasay reservoir, good potential for Colsay reservoir around the edges of the structure and potential fractured basement underlying the discovery also.  Following completion of a deal between Siccar Point Energy and Shell, which completed on 1 May 2018, interest in P1028 and P1189 is held by Siccar Point Energy (70% + operator) and Shell UK Limited (30%).
204/10a-05 (Cambo) (Siccar Point 70% op. Shell 30%) pos. appr. in P1028/1189 block, over 30m oil column (23Â°API), 18m net, 491m horiz section, tested on natural flow for 10 days, rate yet n/a (w.o. pressure buildup). It was target the main Tertiary Hildasay sst. reservoir sequence.
