Neil Cardy, Treasurer

Neil is originally from Sussex and studied Geology at the University of Leicester graduating in 1983. He joined Exploration Logging (ExLog) in 1984 as a mud logger working in the Southern North Sea. After spending a year running slim hole wireline tools for BPB Instruments in the UK and Australia, he rejoined Exlog as a GEMDAS operator. In 1990 he tried to escape from Baker once more and joined Teleco in Aberdeen as a MWD Engineer, this cunning plan was foiled when Baker Hughes brought Teleco and created Eastman Teleco and then Inteq. In 2001, he moved across to Baker Hughes OASIS as a Drilling Optimisation Engineer and continued in various Drilling Optimisation and Application Engineering roles in the UK, Europe and Africa before moving back to the world of mud logging as a Product Manager responsible for pore pressure and rig site geochemistry services. As a result of the downturn in 2015, Neil moved to NOV as their European Drilling Optimisation Manager. In 2016 he set up Longsword Consulting as an independent Drilling Optimisation consultancy, bridging the gap between geology and drilling engineering. Recent projects have included helping develop a low cost slim hole drilling methodology for onshore UK exploration / development and Neil is also one of the founders of Cogent Petroleum. Neil has co-authored SPWLA and SPE papers and has also presented at AFES, LPS and SPE chapter meetings.
