Limited hydraulic fracture growth and productivity in unconventional wells

An operator with wells in an oil-rich sector of the Eagle Ford Shale experienced variability in

Integrated reservoir characterization and multiwell completion workflow design

Two pads with three and five horizontal wells, respectively, were chosen to be studied in the area of interest in the Eagle Ford Shale. The Kinetix software’s workflow was used to evaluate and develop the optimal completion strategies for the candidate wells—all in the Petrel* E&P software platform. A 3D geological model with seismic data; structural definition; reservoir, petrophysical, and geomechanical properties; image logs; and fracturing history with microseismic data served as inputs for creating a robust model for the integrated study.

The stimulation designs were created using a state-of-the-art UFM* unconventional fracture model in the Kinetix software. The microseismic data collected during hydraulic fracturing treatments was used to further calibrate the fracture geometry and footprint.

An important final step in the workflow was to couple the complex hydraulic fracture design to

After the model was calibrated and matched to the observed

Optimized design and well spacing

After applying the optimized treatment designs on a dozen wells in the field, the operator increased
