Simon Hughes holds a B.Sc. in Geology from the University of London (UK). After completion of post-graduate studies in Mining Geology and Mineral Exploration at the University of Leicester (UK), he gained four years’ experience mud logging and formation pressure evaluation on both oil and gas exploration and development wells in the North Sea, Europe, West and North Africa and the FSU. He was then involved in the development of LIBS (Laser Induced Breakdown Spectroscopy) instrumentation to perform the rapid analysis of inorganic elemental data at the rig site. As Senior Geoscientist and Global Technical Support for Halliburton, Simon was responsible for the deployment of wellsite geochemical services on over 85 wells, in both clastic and carbonate reservoirs in the Middle East, North Sea, Brazil, West and North Africa, Canada and the FSU. This involved the use of elemental data to geosteer highly deviated and horizontal wells, pick core and casing points in exploration wells, together with enhanced formation evaluation such as the identification of heavy oil in carbonate reservoirs. More recently he has been involved in the introduction of wellsite geochemistry as an aid to drilling lateral wells in unconventional resource plays in North America, such as the Haynesville and Eagle Ford. This includes application of the elemental data to aid in wellbore placement and also formation evaluation such as the assessment of mineralogy, organic richness and geomechanical properties from drilled cuttings, real-time while drilling. Simon brings some 22 years geoscience experience including 18 years wellsite geochemistry. Simon joined Weatherford as Product Line Manager for Wellsite Geochemistry in 2009. His role included development of a global integrated wellsite geochemistry service to aid in drilling more efficient wells chiefly through better wellbore positioning and enhanced formation evaluation. Integration with more conventional LWD and wireline geosteering and formation evaluation techniques provide better petrophysical interpretation and input into “smart” stimulation and completions particularly in unconventional resources and was key to his role there. Simon recently joined Diversified Well Logging as a senior technical advisor. He is an active member of the AAPG, SPE, HGS and SPWLA.
Meri McCulley holds a M.Sc. in Geology from the University of Houston, with a focus in geochemistry and a strong background in the Permian Basin. Meri began her career in special core analysis at Omni Laboratories in the formation damage testing laboratory. After requisition by Weatherford International, she went on to a 12 year career in petrographic services as a project geologist specializing in interpretive studies integrating cross-disciplinary microscopy analysis, XRD, XRF, ICP, SEM, FESEM, organic geochemistry, formation damage studies, core description, RCA, SRP, CRA, and various other related core analyses. Meri held positions as XRF lab supervisor for Weatherford-Stratum, technical advisor, international business-development, and sales for elemental services and software. Meri has assisted in development of elemental laboratories in Norway, training and technical support in India, and was a member of a peer-reviewed team consulting for the Kuwait Oil Company. Meri joined Diversified Well Logging in 2019 as Technical Sales Advisor and Chemostratigrapher.
Mr. Loos graduated from Maritime College, Rotterdam, in 1977. He has over 30 years of experience and has held various positions in the Oil and Gas industry. He started his career in the industry leading the AMOCO ADF (Advanced Drilling Facility) installations and operations for Exploration Logging, including remote controlled cameras, video and phone links via satellite and designs and certification to DNV 2.7-1 & 2 and A-60 IMO. He designed the first modular heli-liftable Drillbyte mudlogging system for use in South America. As project manager for INTEQ together with Hewlett-Packard he introduced the design of mudlogging’s first integrated Hi Speed FID Chromatograph/Total Gas analyzer and was an integral part of the ELF/Eni-Agip Gas While Drilling concept. He was the originator of the use of U-shaped large ID Coriolis sensors for very accurate Kick Detection measurement mounted in flag position, (Galaxy-II offshore Newfoundland in March 1999). He was also part of the Conoco design team for one of the first Ultra Deepwater DP-3 drill ships Deepwater Pathfinder, and the Exxonmobil teams for Sakhalin-I and Kizomba-A, overcoming design challenges from automated data collection and feedback, extreme low temperatures as to how to accommodate high cuttings sampling rates paired against hi ROP by introducing more ergonomically friendly installations. As product manager for Baker Hughes, Rob invented a new way of measuring block height via RFID technology (patent # 7874351 Devices and systems for measurement of position of drilling related equipment) and was instrumental in launching Geochemistry services for Surface Logging. Working with BASEEFA He led the efforts of introducing Ex Awareness training and certification. He has extensive experience and certifications in areas of compliance (IECEx, OSHA, NEC, IADC competency assurance) and is a certified API Q2 practitioner.
