Well Cementing

Customized Well Cementing Additives to Enhance Your Mix

Maintaining high standards during the well cementing process is a vital step in protecting the quality of well production. For decades, oilfield service companies have counted on YAQOOT AL SAMA's expertise in developing a wide range of cementing additives that provide a competitive advantage and flawless results in their cementing process.

Whatever the reservoir environment, YAQOOT AL SAMA's cement additives are designed to modify the characteristics and performance of cement slurry so that it functions under the wide range of conditions that occur inside the wellbore.

Extensive Cementing Product Line

YAQOOT AL SAMA's large host of high-quality liquid and powder additives can be used to modify slurry properties such that each service company can design its own unique slurries for every individual well. In order to provide clients with optimized cementing processes, we provide the following products:

Cement Fluid Loss Control Additives

Operators can confidently incorporate YAQOOT AL SAMA fluid loss additives into a cement system without adverse effect on thickening time or compressive strength. When using these fluid loss additives, cement homogeneity and flow are retained. Fluid loss additives also prevent formation damage by discouraging cement filtrate.

• Maintain slurry homogeneity and desired flow properties
• Promote gas migration while offering fluid loss control
• Improve remedial (squeeze cementing) success rates
• Maintain cement slurry density and cement column uniformity
• No impact on cement thickening time
• Won't inhibit the development of compressive strength

Anti-Settling Agents

Guard against sedimentation and free-fluid formation with the addition of YAQOOT AL SAMA's anti-settling agents to your cement slurries. Both your cement and any accompanying additives are held in suspension by anti-settling agents in order to allow the cement to settle properly without the inclusion of sediment solids.

YAQOOT AL SAMA's anti-settling agents work according to the demands of your complex cement slurries and are effective across an expansive temperature range.

Expanding Additives

For premium zonal isolation, you need to be certain that your cement and formations and casings are securely sealed. The expanding additives offered by YAQOOT AL SAMA effectively cause the cement to swell so that it forms a strong and fast bond to formation and casings.

Expanding additives by YAQOOT AL SAMA are effective in a range of temperatures, even those higher.

Cement Spacers

Cement Spacers are indispensable for diverting drilling mud and oily residue from the cement slurry as well as from related surfaces.

Trust YAQOOT AL SAMA's cement spacers to ready your wellbore for cement and establish the ideal environment for zonal isolation. These spacers effectively clear the annulus of mud and drilling fluid, leaving its surfaces wet but oil-free, thereby enabling it and the casing to accept a cement bond.

Chemical Washes

Removing oil-based or emulsion mud after drilling can be challenging. YAQOOT AL SAMA offers a range of chemical washes aimed at addressing residual drilling muds. Acting to reduce these muds to a water-like density and viscosity, YAQOOT AL SAMA's chemical washes assist spacers in flushing away muds from holes and wellbores and leaving casings water-wet.

The oil-based and water-based varieties of YAQOOT AL SAMA's chemical washes tackle a range of muds according to your needs, and prepare the way for your cement.

Cement Retarders

At times it's necessary to extend the thickening time for cement slurries, whether to adjust for volume, pump rate, or temperature. These circumstances call for effective cement retarders. YAQOOT AL SAMA offers cement retarders that accommodate for a range of situations:

• High slurry volume
• Slow slurry pump rate
• Effective in a range of temperatures wellbore environments

Look no further for cement retarders that deliver steady, dependable results, regardless of fluctuating temperatures or complex cement slurries. YAQOOT AL SAMA's cement retarders come in both liquid and dry varieties to better suit your specific needs.

Cement Dispersants

Improve cement flow properties and reduce water requirements with YAQOOT AL SAMA's cement dispersants.

Cement Defoamers

The entrainment of air during mixing can cause foaming, which can compromise the density of your cement slurries. Adding YAQOOT AL SAMA defoamers to your cement slurries can combat air entrainment and facilitate the achievement of the right slurry density for your cement.

YAQOOT AL SAMA defoamers work to penetrate foam or to supply a film over the foam's surface, collapsing the foam and improving slurry density. These defoamers are suitable for cement slurries containing such foam-producing agents as cement retarders and cement fluid loss additives.
