The EPA© application was created to mechanize the calculation of casing hole sizes and perforation length for a given gun system in a given well configuration. The application uses the “Method of Equivalents” presented by Ed Colle and Ken D. Honeycutt as the basis for these calculations. The “Method of Equivalents” uses API RP 19B Section 1, Section 2, API RP 43 Section 1 and mild steel penetration data to calculate the mild steel equivalents for the fluid, cement and formation. These equivalents are then used to calculate the perforation length and casing hole sizes. The “Method of Equivalents” is the only method currently being used by the oil and gas industry that will reproduce API Section 1 and Section 2 data with zero error. It is extremely important that any method accurately duplicate surface data since it is virtually impossible to confirm the performance at normal working depths.

The EPA© is a 2-tier application. EPA© is an upgraded version of the original EPA program (DOS based) and contains improved calculation methods. The application uses a graphical user interface (GUI).
