Emerging Best Practices Ensure Fracture Effectiveness Over ...

The blue wells typically were treated in five or six stages, while the red wells averaged 28 stages. Adjacent operators have completed 23 wells in the surrounding area with frac sand (green dots). The cumulative production trends are shown in Figure 5. These wells were completed with 20 frac stages.

Fracturing unconventional formations to enhance productivity

To adequately enhance the productivity of the fractured well, achieving a large stimulated reservoir volume (SRV) by means of having complex fractures is important, if not vital. The accepted way to achieve the required large SRV is to drill a horizontal well and fracture with extensive use of multiple stages.

EPA Hydraulic Fracturing Workshop March 10th - 11th, 2011

The actual deviation survey for the well that is being modeled, as well as the planned perforations for the well, are entered. A pump schedule is entered into the fracture model. Numerous iterations with different pump schedules, perforation schemes, and other variable modifications are run to "optimize" the design.
