Alba Mineral Resources plc (LON:ALBA) is pleased to announce that it has been advised by the operator, Angus Energy Plc (LON:ANGS) that, further to the 18 January 2017 announcement, work to complete, log, case and cement the well at the Brockham oilfield has now been successfully completed and potential reservoirs have been logged in all 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.
George Frangeskides, Alba Mineral Resources plc Executive Chairman, commented: “We are pleased to learn that hydrocarbon shows, which we understand were missed in the previous drilling by BP in 1987, have been encountered in the Portland and the three Kimmeridge target intervals. The reported oil and gas shows in the underlying Corallian are also very encouraging.
We understand from Angus Energy that analysis is underway to identify the extent of hydrocarbon presence and the ability of these hydrocarbons to freely move into the wellbore and that the use of New Ultra Wave well logging technology will, once the results are analysed, enable us to target the most prospective zones which have the highest potential for future production.”
