Production optimization starts with well-project completion, and an ideal completion depends upon the integrity of the significant cementing job. The poor job becomes the reason for extra costs and losses to the oil & gas industry every year.
Poor cementing jobs need extra operations like squeeze jobs. These functions are time-consuming and rig-demanding, which can become the cause of economic loss. Suppose a poor cement job is left unattended; the result can be drastic and ensure a lot of damage. Simply put, it can destroy all procedures, so you must reduce these problems.
Cementing integrity is enhanced with a circulating mandrel hanger that permits the casing to move through the lateral heel during installation.
Cement activities in the oil & gas field are getting a bad rap. Cement work has been the possible culprit in most onshore franking disputes. The United States Bureau of Land Management reports that bad cementing work becomes the reason for accidents.
But no worries! There is a chance of improvement in cementing technologies to reduce the threats. The integrity of the job employs all the assistance it can get.
The method in which the process is inside the annulus helps with the integrity aspect of the cementing functions, and the wellhead can assist in accurately enhancing the cement placement’s efficiency.
It is a critical process for good integrity. It ensures hydraulic isolation and mitigates the fluid flow in the middle of the producing zones, groundwater aquifers, and the ground. However, cement sheaths are not always perfect for delivering an acceptable long-term solution for demanding drilling surroundings.
The Changes in downhole conditions, along with pressure & temperature fluctuations, can become the cause of stress on the cementing sheath. The mechanical qualities of suitable cement types have become the subject of considerable interest lately.
The drilling engineers and expert cementers are moving away from the sole measurement of compressive power in press machines & ultrasonic analyzers to a more detailed study of properties.

The process can fail because of shear and compressional stresses during the life of a well. These different stress conditions make a connection with cement sheath failures:
When the set process in the wellbore faces such problems and stresses, the set cement can fail in the shape of radial, circumferential cracking. This failure compromises zonal isolation and welcomes other swear issues throughout the process.
Solid material for cementing will deform when a load is employed on it. A stiff material requires more strength to deform than a soft material. So, let’s uncover the secrets of improving cement flexibility.
Cement with upgraded flexibility can overcome the potential for stress-induced cement-sheath cracking. It may become the cause of long-term gas migration.
Flexible components, elastomeric polymers, or latexes are employed in existing cementing systems. They all need to enhance flexibility together with foamed cement.
You can utilize the following strategies to enhance flexibility in an approach to better zonal isolation.
Conventional slurry density reduction can boost the flexibility of the set cementing process. Also, the impacts on compressive power and permeability are detrimental in this scenario. Foam types of cement can boost flexibility, which is linked to its reduction of density and porosity.
You can add different fillers, such as carbon black, calcium carbonate, and silica. These filters can optimize the elasticity of the set cement. Also, rubber components or thermoplastics can bring a lot of improvements.
Once used, the resulting set exhibits enhanced elasticity and, in most cases, such expansion properties. An extra value of these parts is having special gravities between 0.9 & 1.2. So, they can also overcome the cement system density and improve the process.
Fibers or ribbons are the most elementary particles to adjust the entire process. They can add something more potent to a cement matrix to upgrade flexural strength.
Nylon fibers have been employed for many years to fulfill this cementing purpose. This strategy has its background. Furthermore, the metallic micro ribbons can help to enhance impact resistance & toughness in kickoff plugs and different junctions.
Cementing is customarily employed in wells as the crucial material for zonal isolation. It can ensure operational limitations and alternative materials and offer significant benefits over cement, which is being proposed & employed by the industry.
