Multi-scale (single cutter and full bit) oil & gas drilling Simulations
Oil and gas and other associated drilling process involve a detailed understanding of the fluid mechanics, rock geomechanics, tribology, and the thermal sciences. The PFTL employs a host of experiments and modeling approached to elucidate the physics of drilling in order to predict downhole performance and to enable the design of smarter drilling tools and equipment.
