Drilling & Completion Tech Digest

Sinopec group sets depth record on Sichuan Basin HPHT well Sinopec Research Institute of Petroleum Engineering (SRIPE) and APS Technology have achieved a depth record on a high-pressure, high-temperature (HPHT) well in China. SRIPE completed drilling two sections of Well YuanBa272H in China’s Sichuan Basin in April, with true vertical depth of 6,670 meters (21,883 ft), total depth of 7,580 meters (24,869 ft) and a horizontal section of 600 meters (1,968 ft). The APS SureShot MWD tool that was used encountered temperatures as high as 147°C static and 138°C circulating and pressures up to 140 MPa (20,305 psi) during the job. “Despite the challenges of high flow velocities, high hydrogen sulfide, high vibration and high shocks, the APS SureShot MWD ...
