How a drilled well is made ready to produce — running and cementing casing, perforating the reservoir, and installing the wellhead and production equipment.
Well completion is everything that happens between finishing drilling and first production: running and cementing the production casing, perforating the casing across the reservoir, stimulating the well (often by hydraulic fracturing), and installing tubing and the wellhead or Christmas tree.
A good completion isolates zones, protects freshwater, and connects the reservoir to the surface efficiently. This guide covers each step.

Completing a well means preparing a drilled hole to produce — installing and cementing casing, perforating the reservoir, stimulating it if needed, and fitting the production tubing and wellhead so hydrocarbons can flow safely to surface.
Casing is the larger steel pipe cemented into the wellbore to line and stabilize the hole. Tubing is the smaller pipe run inside the casing through which the oil or gas actually flows to surface, and which can be pulled and replaced during workovers.
Cement fills the annulus between casing and rock to isolate zones, protect groundwater, support the casing, and prevent fluid migration or blowouts. Poor cementing is a leading cause of well-integrity failures.
