Aubrey Whymark BSc MSc FGS
Wellsite Geologist, Geosteerer & Biosteerer
KEY EXPERIENCE AREAS
I am primarily a highly experienced geosteerer. My job encompasses the role of wellsite geologist and I routinely drill vertical and deviated wells. I am a qualified and experienced micropalaeontologist (foraminiferal) and an accomplished biosteerer. My key areas of experience are:
  • Geosteering and biosteering horizontal wells, from ultra-short radius to extended reach.
  • Coiled tube drilling. Conventional top-drive and kelly rigs.
  • Underbalanced and overbalanced drilling.
  • Well planning, pilot studies, end of well reporting and post drilling appraisals.
  • Log correlation and interpretation.
  • Judging landing points, casing points and coring points.
  • Age dating using microfossils from Jurassic to recent (primarily using foraminifera).
  • Working in structurally complex geological settings.
  • Sample collection and preparation methodology.
  • Reporting and presentation.
  • Supervision, quality control and contributing towards a safe working environment.
SUMMARY OF WELLSITE EXPERIENCE
  1. 72 Wells Onshore Qatar
    Qatar Petroleum: Dukhan Field
    I am currently working onshore in the Dukhan Field for Qatar Petroleum. I am involved in top-hole, build and horizontal sections, which target the thin and laterally variable carbonates.
  2. 23 Wells Offshore Qatar
    Maersk Oil Qatar: Al Shaheen Field
    I worked offshore in the Al Shaheen Field for Maersk Oil Qatar. I was involved in top-hole and horizontal sections targeting often thin Cretaceous carbonate and clastic reservoirs.
  3. 104 Laterals in UAE
    BP Sharjah Ltd & Margham Dubai Establishment: Sajaa and Margham Fields
    Sajaa Field (Sharjah) and Margham Field (Dubai) lateral wells are onshore United Arab Emirates, drilled with an underbalanced coiled tube drilling (CTD) rig. Laterals targeted the carbonate Thamama Group in areas of complex folding, high angle faulting and thrust faulting. 104 laterals were drilled from 24 well locations.
  4. 22 Wells in Oman
    Petroleum Development Oman: Lekhwair, Fahud and Dhulaima Fields
    Lekhwair Field wells are onshore Oman. The build and horizontal sections were monitored / biosteered / geosteered. The lateral sections targeted the carbonate Thamama Group, Shuaiba Formation (and very occasionally the Kharaib Formation). Horizontal drilling records were established during the course of this work.
  5. Office based studies
    Fugro Roberston Ltd
    I have undertaken numerous single and multi-well research, proprietary and multi-client projects. These have been from stratigraphically and regionally diverse areas. Regions of study have included Kuwait, UAE, Yemen, Oman, Pakistan, Turkey, Libya, Egypt, Equatorial Guinea, Ireland, North Sea, East Coast USA, Canada and Brazil.
