Four operators drilling in the Eagle Ford Shale Play located in South Texas, USA joined in an initiative to acquire various types of open hole logging data in several horizontal wells, and then use the data to design the completions with optimum fracture stage and perforation cluster positioning. The wells were then evaluated with horizontal production logs to gauge the effectiveness of using the log data to engineer the completions. The idea was to test the theory that by grouping rock with similar properties it would be possible to improve the effectiveness of the hydraulic fracture treatments and consequently improve economic performance. Perforation efficiency was used as a metric to evaluate the success of this test. This presentation discusses the methodology and results of the consortium wells.
