China Petroleum & Chemical Corp. (Sinopec) struck sizeable oil and gas flows in the deep Yuejin 3-3XC well of its Project Deep Earth NO.1 in Tarim basin, Xinjiang Uyghur Autonomous Region, China. Liquid flow is 200 tonnes/day and gas flow is 50,000 cu m/day.
The well was drilled to a depth of 9,432 m, breaking the record of the deepest onshore well in Asia, the company said. The well was designed for a horizontal distance of 3,400 m (OGJ Online, May 10, 2023).
Project Deep Earth drills into the Shunbei ultra deep carbonate condensate and gas reservoir in Tarim basin. The reservoir has an average burial depth of more than 7,300 m and contains 1.2 billion boe total recoverable reserves.
