Well completion is actually the fracking stage of the gas development process. It follows the drilling of the well. A drilled hole by itself, generally produces nothing, but the hydraulic fracturing, the well completion process, activates the well.

- "Once a well has been drilled to total depth (TD), evaluated, cased and cemented, engineers complete it by inserting equipment, designed to optimize production, into the hole. The driver behind every well completion strategy, whether for a complex or basic well, is to recover, at a reasonable cost, as large a percentage of the original oil in place (OOIP) as possible.
The decision to case and cement a well for production or plug and abandon it as a dry hole relies heavily on formation evaluation (FE) using open-hole logs. For the purposes of this article, completion refers to all operations following the placement of cement behind the production casing, which is performed after FE."
