Case study details
Our customer in Northeast China was experiencing difficulties drilling in the hard and abrasive rock formations of the Daqing natural gas field. The pay zone is a lateral section that consists of igneous rock at a true vertical depth (TVD) of 3,000 m (9,842 ft) and unconfined compressive strength (UCS) is estimated to be greater than 25,000 psi.
Average wells were taking 80 to 100 days to total depth (TD) and required approximately 20 drill bits due to severe coring damage to the center of the bit.
