Successful fracture treatments may increase the productivity of a well up to 400% relative to a zero skin well. The fold of increase might be more if there was damage in the well. This may result in substantial CAPEX savings (fewer wells per field necessary) or extend the field’s economic life. Hydraulic. . The criticality of hydrofracking additives is always high. Not only will we have to select or tune them for each application, but quality control on. . Generally, there will be great care in planning a frac to get the right Frac size and shape after evaluating all the available log and core data and running numerous computer. . The productivity increase due to the fracturing process is a function of the following: 1. Fracture length, 2. Fracture conductivity, 3. Fracture/wellbore communication, 4. Reservoir permeability, and 5. Near-wellbore damage (skin). It is difficult to lay down. [pdf]
