The concrete mix is an important factor for achieving good quality in slipformed construction. Some parameters of the concrete mix (setting time, slump, etc.) should be reviewed, but there is no special concrete required for general slipforming. A typical 'pump mix' with 3 to 4 in. of slump is mostly adequate.

Well completion is generally broken down into three phases: Casing – where the piping is run and the cement casing is pumped in. Perforation – where holes are blasted through the casing at precise locations for stimulation and production flow. Often done in conjunction with tubing, packing, and setting up the Christmas tree.
