Angus Energy plc confirmed that, further to the 18 January 2017 announcement, work to complete, log, case and cement the well at the Brockham oilfiled has now been successfully completed and potential reservoirs have been logged in the Portland, Kimmeridge and Corallian layers with all three formations having hydrocarbon shows. The 6" hole has been electronically logged using quad combo and Ultra Wave fracture analysis, it has been cased and cemented, whilst the old open hole side-track has now been abandoned and cemented up back to inside the main well casing. The well will now, upon OGA confirmation, be renamed BR-X4Z. Further log analysis and laboratory work is currently being undertaken to provide a better understanding of the Kimmeridge and other formations, but from the evidence so far, these appear to be the same in structure to the oil bearing Kimmeridge sections in the nearby Horse Hill-1 well. Notably, the Corallian formation, which lies immediately below the Kimmeridge, had both oil and gas shows.
