Ashley is a geophysicist and geostatistician whose career has encompassed over 20 years world-wide oil industry experience of exploration, development and production geophysics. He has also consulted to the nuclear and engineering sectors on subsurface definition and uncertainty. Since 1993 he
has specialised in geostatistics in addition to geophysics.
Ashley has worked in or on behalf of service companies, consultancies and oil companies in North and South America, Europe, Africa, Middle East, Far East and Australia. He spent 5 years with LASMO plc in Technical Services assisting and advising asset teams worldwide in geophysics (particularly inversion), geostatistics, risk and uncertainty.
After leaving LASMO, Ashley founded Earthworks, a consultancy specialising in subsurface geoscience, based in Salisbury, Wiltshire, UK. His innovative ideas are
now being developed in new and ultra-fast stochastic seismic inversion software at Earthworks.
He lectured in Borehole Geophysics to Honours Graduates at the University of the Witwatersrand, South Africa 1989-90 and was a Visiting Research Fellow at the Post Graduate Institute in Sedimentology, University of Reading, UK 1995-97. He continues to teach geostatistics to MSc Petroleum Geoscience students
at Imperial College, London, a role he began in 1999.
His current geostatistical course has been running successfully since 1996 and the newer inversion course since 2000. Both courses are also run as part of the Geoscience Training Alliance consortium in London and in Houston and are widely acclaimed by participants.
Ashley is a committee member and regular attendee at the SEG Development and Production Forum. He was Chairman of the 2000 meeting and the 2003 meeting. He presents widely at conferences on the subjects of geophysics and geostatistics, his most recent paper being on deterministic and stochastic inversion at the PETEX 2002 conference, Olympia, London. Ashley is a member of SEG, EAGE, IAMG, BSSS, IPSS, IAS and PESGB.
