Abstract:

The invention of diamond synthesis in the 1950s led to polycrystalline diamond

cutters (PDC) that revolutionized oil and gas drilling. Early PDCs worked only for

short intervals in soft formations, but technological advances extended their

reach in harder rock, boosting U.S. shale drilling efficiency almost threefold over

the last two decades. Effective problem-solving at the dull bit level with good

drilling context improved PDC reliability, and these advancements now benefit

geothermal energy projects where PDCs remain highly cost-effective. This talk

will highlight strategies for increasing PDC performance in hard rock, including

granite, through identifying and addressing root-cause failure modes in a

collaborative process.

Biography:

Neil has been part of the effort at US Synthetic to improve the strength,

toughness and thermal stability of polycrystalline diamond cutters (PDC) for the

oil and gas industry for over 20 years. He has worked closely with PDC bit

manufacturers throughout the world, testing and developing PDC’s for drilling in

challenging formations. He has extensive experience in cutter forensics and

currently works with a team of scientists and engineers to develop products that

help the industry drill more efficiently in hard rock, including geothermal

formations. Neil received a Master of Science degree in mechanical engineering

from Brigham Young University and is fluent in Mandarin Chinese.
