Title: Deep drilling basic research program shear bit design. Final report, March 1990-October 1995

Technical Report ·
OSTI ID:484710

Maurer Engineering Inc., under contract with the Gas Research Institute, evaluated drilling of deep gas wells to determine future research projects. The candidates providing the best possibility of success and maximum savings are PDC/TSP shear bits, slim-hole drilling, roller-cone bits, and downhole motors; of these, improvements in shear bits have the best opportunity for near-term results. Significant RD&D was conducted to optimize TSP bit design and efficiency for improved performance in deep drilling. Results of the Deep Drilling Basic Research Program showed that: Improvements in shear bits are the best way to reduce costs and increase efficiency of deep drilling. Changes in cutter size, density, and orientation significantly impact the penetration rate and life of TSP shear bits. Power delivered to the rock controls penetration rate. Higher power rates mean faster drilling. Correctly designed TSP shear bits can deliver more power to the rock.
