The Changbei tight gas reservoir has presented a number of challenges in successful application of fracture stimulation techniques. In an appraisal program, 4 wells have been fracture stimulated. Issues related to fracture containment and high fluid leak-off in coal layers above and below the sand reservoir have led to a number of design and operation challenges. The fractures placed have led to significant production improvements, up to a factor of 10 over pre-frac production. This paper gives an overview of the treatment operations, and without going into details of fracture design and execution, key aspects are outlined and their implications discussed.
