Doriemus PLC has announced that US-based Nutech Ltd, one of the world's leading companies in petrophysical analysis and reservoir intelligence, has independently assessed the Brockham-1 well. Drilled by BP in 1987 under UK Production License PL 235, this Weald Basin well sits approximately 6 miles north west of Gatwick Airport, with an estimated total oil in place (‘OIP’) of 281.7 million bbls of oil per sector or per square mile inclusive of all reservoirs within the well.
In comparison, Nutech’s previous reported OIP assessment of the nearby Horse Hill-1 well (HH-1), located approximately 4.5 miles from the Brockham play, reported a total of 158 million bbls OIP per square mile last year. This excluded the previously reported Upper Portland Sandstone oil discovery previously announced on 9 April 2015. The flow testing of the HH-1 well, as announce on 21 March 2016, reported a total aggregate stable dry oil flow rate of 1688 bpd from two of the three Kimmeridge Limestones and the Portland Sandstone. The pay zones successfully flow tested at HH-1 in February and March this year are similar to those seen in the Brockham-1 well.
Doriemus is a partner in the planned Brockham sidetrack and will take advice from Nutech in order to provide input and suggestions to the operator.
David Lenigas, Executive Chairman of Doriemus Plc, commented:
“The great advantage of the Brockham oil field is that it is already a producing oil field and any new production should be able to be put on line relatively quickly. This Nutech work for Doriemus has highlighted that the conventional Portland Sandstones and the Kimmeridge Limestones that were oil productive at the Horse Hill -1 well near Gatwick Airport are indeed evident at the nearby Brockham Oil Field. Doriemus looks forward to participating in the next phase of developing the oil potential of Brockham with the proposed drill of the next side track well designed to penetrate the Portland and the entire Kimmeridge sections of the well."
Bill Boykin, NUTECH Energy’s EVP Business Development, commented:
“From the initial NUTECH petrophysical and reservoir analysis, we are excited about the potential of the Brockham oil field. It is early in the assessment with limited data, but we are looking forward to updating the reports as additional information comes in from log/core data from new drills and additional production data from completions.”
