Fracking (Pt. 4)

Proppant Selection After the pumping process has been completed and the fracture created, it must now be held open. This requires the proppant, it will physically hold or prop the fracture open thus promoting the flow. The most important characteristic of the proppant is its ability to withstand compressive forces, thus its compressive strength is …

Fracking (Pt. 3)

The design process: Select a fracturing fluid Select a proppant Determine the maximum allowable pressure Select a fracture propagation model Select treatment size Perform production forecast Perform NPV analysis Once in the field the following must be known: Specifications of the fracturing fluid and the type of proppant Fluid volume and proppant weight requirements Fluid …
