191442 – Getting More Out of Your Multistage Fracturing Openhole Completion

Summary

Saudi Aramco Production Engineering Division currently performs multistage fracturing operations using plug and perf completions, to target tight gas reservoirs requiring stimulation. To improve operational efficiency, eliminate wireline intervention and coil tubing milling operations, the decision was made to test an openhole multistage fracture system. This is the first time an openhole multistage fracturing system combining mechanical and constrictor swell packers has been deployed to promote limited entry diversion. This qualified and field-tested novel completion methodology ensures proper fracturing diversion between frac-ports located within the same stage.
