PetroChina has awarded Baker Hughes a contract to supply 77 multistage openhole fracture completion systems for horizontal wells in the tight gas sands of the Changquing Field, China's second largest onshore oil and gas field.

摘要

Baker Hughes was awarded the one-year contract based on successful deployment of its Frac-Point technology in the Sulige gas field in 2009. PetroChina is expanding its horizontal well, multistage fracturing activities to increase gas production from the tight gas sands in the Changquing Field. Characterized by low permeability, low pressure and low yields, reserve recovery from Changquing is technically complex – requiring innovations like multistage fracture completions to overcome the geologic challenges.
