Jun 14 2017 · Its purpose is to ensure that the casing shoe is surrounded by high quality cement to keep the end of the cement from becoming contaminated with drilling fluid and to provide a pressure indication via plug bump that the cement displacement is complete. Drilling the shoe track can go smoothly in one well and be problematic in the next.

the KOP. In these scenarios operators can use the TrackMaster OH-C openhole whipstock and cementing system (left). This system lets the driller set a whipstock and a cement plug beneath it in a single trip. Because the anchor holds the whipstock in place the operator can sidetrack the well without waiting for the cement to cure.

Another term for tie-back liner a section of liner that is run from a liner hanger back to the wellhead after the initial liner and hanger system have been installed and cemented. A tie-back liner may be required to provide the necessary pressure capacity during a flow-test period or for special treatments and is typically not cemented in place.

Inventing a Cement Service Company. After World War I as Halliburton struggled to set up cementing operations in Texas many oil companies were skeptical of cementing casing according to the former editor-in-chief of E P magazine. "Most wells were doing well they reasoned without the new-fangled technology and there was in the back of their minds the question of possible well damage

This is done by using spacers to fully displace drilling fluid from the annulus and condition the casing and annular surface to accept a cement bond. Spacers and flushes are intended to displace drilling fluid from the annulus leave the casing and formation water-wet (free of oil) and separate drilling fluids from the cement slurry.
