Cementing Operation - an overview |

Squeezing or remedial cementing is a common operation in the petroleum industry [14]. Squeeze cementing is most often performed to repair leaks in well tubulars and to restore the pressure integrity to the wellbore or restore a cement sheath behind the casing. Squeeze cementing coupled with coiled tubing has been a standard remediation technique for shutting of unwanted gas or water production.

Example Calculation 9.5/8in Casing Cementation |

9.5/8in casing capacity from cementing head (assumed to be at drillfloor level) to float collar is: 4 954 ft x 0.0732 bbls/ft = 363 bbls. After the top plug has been dropped, 5 bbls of water behind will be pumped. So the total displacement volume, to be pumped with the rig pumps is: 363 bbls - 5 bbls = 358 bbls. Using 0.2013 bbls/stroke for 100 % efficiency of the mud pumps, this equals: 1 778

What Is The Cementing Process?

Cementing. Cement injection is a key process after casing entering the well. Its function is to seal the annular space of the casing and the well wall to seal the oil and gas water layer, so that the casing becomes a passage for oil and gas to pass into the well. 3. Oil well cement. Oil well cement is an important material for sealing the casing and the annular space of the well wall. Because

CEMENTING PROCESS FOR CARBON ARTICLES

A process is given for cementing together carbon components which are to be used at high temperatures, e.g., 1000 to 2500 deg C. The process comprises coating the surface of one component with a cement consisting mainly of furfuryl alcohol, contacting the two components, resinifying the cement, and finally carbonizing the cement by heating to above 1000 deg C in an inert atmosphere.

The process of cementing is performed by deploying the cement slurry into the well through pumps that displaces and replaces the drilling fluids still present in the well. Petropedia explains Oilfield Cementing.
