A Complete Overview
Oilfield cementing is known as the developing & pumping of cement into a wellbore. Cementing is committed to protecting and sealing a wellbore. Cementing provides zonal isolation, and Oilfield cementing pumps cement into the wellbore.
It is part of preparing a well for further drilling process and production or abandonment. This exclusive process is used for many reasons; usually, it is utilized to cut off water penetration into the wall permanently.
Purpose of Oilfield cementing process:
Also, it is a part of the whole process of a prospective production well, and cement can be utilized to close up the annulus after a casing string has been run in a wellbore. Furthermore, Oilfield cementing is used to shut off a lost circulation zone or an area where there is a possibility of reduction or absence of flow in the wellbore.
In the directional drilling process, cementing is utilized to plug a previous well in the case of running a directional well from that point. In addition, a cementing procedure is used to plug a well or sinkhole to abandon it.
The cementing process is performed in that scenario; when the cement slurry is deployed into the well through the pumps, displacing the drilling fluids still placed within the well and substation them with cement. The cement slurry flows into the bottom side of the wellbore through the casing.
It would gradually flow to the pipe through which the hydrocarbons flow to the actual surface. It fills in the space & holes between the casing & the wellbore and hardens. This process will ensure a seal so that outside materials can’t enter into the excellent flow and always position the casing in place.
What is Zonal isolation?
Zonal isolation is an essential part of Oilfield cementing that is not directly in link with the production, but this is an important task. It must be performed in an ineffective way to permit production or stimulation procedures. The victory of a well depends upon this primary procedure. Furthermore, it also supports isolating oil-and-gas- and water-producing zones. Cement also aids in the following areas;
- Shield the casing from corrosion
- Avoid blowouts by quickly forming a shut-off
- Protecting the casing from various shock loads in in-depth drilling
- Sealing off zones of lost circulations or thief zones
Oilfield cementing: 2 broad Categories
Primary cementing is an exclusive process that is used to provide zonal isolation. Cementing is a blending slurry of cement, cement additives & water. As well as pumping it down through the casing to main points in the annulus that are around the casing or in the open hole under the casing string. The two fundamental functions of the cementing procedure are:
To bound fluid movement in between the formations
Make a strong bond and support the casing
If these functions are achieved effectively, other requirements will be imposed while the life of the well would be met, including:
- Government regulations
Remedial cementing is a process that is usually done to solve many problems that are associated with the primary cement operation. The most perfect and economical approach to remedial cementing is to prevent it by thoroughly strategic planning, designing, and executing all drilling processes, primary cementing, and completion functions. Remedial cementing required to restore a well’s operation indicates that primary functional planning & execution were unproductive, resulting in costly repair operations. Remedial cementing operations consist of 2 main categories:
- Squeeze cementing
- Plug cementing
Cement placement procedures; step by step guidance:
Typically, five basic steps are needed to obtain a successful Oilfield cementing operation and meet the previously outlined functions.
- First of all, analyze the good parameters, explain the requirements of the well, and then design & structure placement methods along with fluids to meet the demands for the life of the well. Fluid properties, fluid mechanics, & chemistry influence the design utilized for a well.
- Let’s Calculate fluid (slurry) composition and perform required laboratory tests on the slurry designed in Step 1 to see that they meet the demands or not
- Use essential hardware to implement the design in the 1st step; calculate the volume of fluids (slurry) to be pumped; mix and pump the slurry into the annulus.
- Observe the treatment in real-time; compare it with Step 1 and make necessary changes.
- Determine the outputs; compare them with the design in Step 1 and make changes as necessary for further operations.

What is Oilfield cementing?
Oilfield cementing is the complete process of developing & pumping cement into a wellbore. Cementing assists in safeguarding and closing off a wellbore.
What is the cementing process?
In the minting, coining or coinage is the procedure of manufacturing coins by using a kind of stamping; this approach is used in both hammered coinage & milled coinage. This “stamping” procedure is different from the process used in cast coinage.
