CONTROLLED DRILL BIT METAMORPHISM (DBM) USING INDOOR RIG FLOOR EXPERIMENTS

Summary First time controlled drill bit metamorphism experiments using one-of-a-kind laboratory in Pau, southern France, with indoor rig floor with full capacity of controlling drilling conditions and with a closed drilling fluid loop, allowing extraction, analysis and sampling of the mud gas while-drilling, showing alkanes and alkenes being generated, as drilling conditions create more heat. Stepwise increase of WOB or RPM is followed by likewise increase in generated DBM-gases via base oil cracking at the bit cutter-rock interface.
