Inefficient fracture initiation is the largest reoccurring problem encountered when completing horizontal Barnett shale wells. These difficulties have manifested themselves as high-fracture initiation and propagation pressures which lead to low injection rates and high treating pressures. These losses reduce the efficiency of proppant placement and stimulation.

As drilling activity has increased over the past couple of years, fracture-initiation problems are now a substantial source of expense and downtime. This field study examines 256 horizontal Barnett shale wells in an effort to identify the causes of these near-wellbore issues, and to offer corrective solutions for future completions.

The goal of this study is to recommend an optimized completion strategy to minimize these near-wellbore problems, increase stimulation coverage, and decrease unplanned completion expenses.
