The Defining Series: Well Cementing Fundamentals | SLB
Well cementing consists of two principal operations—primary cementing and remedial cementing. Primary cementing is the process of placing a cement sheath in the annulus between the casing and the formation.
Cementing Tools & Equipment In Oilfield Complete Guide
Dec 7, 2021 · Here, we will discuss in detail the major surface cementing equipment and downhole cementing tools that are used in oilfield cementing jobs
Cementing Services - SLB
Cement supports and protects well casings and helps achieve zonal isolation. Critical to safer, environmentally sound, and profitable wells, zonal isolation is created and maintained in the wellbore by the cementing process.
PEH:Cementing - PetroWiki
Aug 2, 2024 · A method commonly used on conductor or surface casing to bring the top of the cement to the surface consists of pumping cement through tubing or small-diameter pipe run between casings or between the casing and the hole. …

Cementing Operations - SLB
The cement sheath created during cementing is critical to establishing and maintaining zonal isolation in the well, supporting the casing, and preventing external casing corrosion. Evaluation of the cement sheath may be enhanced by an integrated approach in which engineers consider cement evaluation logs in the context of drilling and cement ...
Cementing operations - PetroWiki
Jan 15, 2018 · Cement is used to hold casing in place and to prevent fluid migration between subsurface formations. Cementing operations can be divided into two broad categories: primary cementing and remedial cementing.
Basics of Wells – Cementing: How Effective is Cement in Creating Barriers? During drilling, each section of a well is cased (a length of pipe is place to cover the well from surface to the bottom of a section) and liquid cement is pumped down the pipe and forced up the annulus
