Cement Additives is a Chemical Additive that is added to the Drilling Cement Slurry to optimize the properties of the Drilling Cement and achieve the desired Properties for cementing.

During the Cementing operations the Temperature ranges from Below Freezing to 350°C (660°F) also the Pressure ranges from Ambient to almost 30,000 PSI, cement additives must perform in such conditions.

Global Drilling Fluids and Chemicals LTD has a Cementing Division that is primarily Designing and manufacturing customized cementing Additives for a Range of Cementing applications our Comprehensive Drilling Cement Additive Package is cost effective and High Performance and reliable way to place the Cement Slurry between the casing and the Wellbore formation.

GDFCL is a Complete Source and a One stop Shop for all your Cementing Additive needs. GDFCL manufactures full range Cementing slurry additives which can be customized and manufactured according to various customer needs such as varying temperature, well requirements and specifications.

GDFCL  Manufactures a Wide Variety of specialized Cementing additives for Oilfield Applications. Our Product Portfolio Includes: 

Our Product Range of Cementing Additives for Oil Drilling Applicaitons: 

• Cement Retarder:  Cementing additives to Increase the Setting Time of the cement. They are specialty cementing slurry additive used to increase the thickening time for cement slurries to enable proper placement and is applicable for primary and secondary cementing jobs and is compatible with all API Oil well cements. They have good dispersing and fluid loss properties Retarders  Manufactured by GDFCL are classified into various different product categories and can be customized as per customer requirements with varying temperatures and wells.
• Cement Dispersants and Friction Reducer: Cement additives added to the cement slurry to lower the viscosity and improve fluid flow properties, early strength development, improves and reduces cement contamination.
• Cement Fluid Loss control Additives (FLC): cement additives that control the Fluid Loss of the Aqueous Phase into the formation and are designed of oil well cementations and is used as a fluid loss agent and viscosifier. Cement fluid loss control chemicals manfuactured by GDFCL is used for designing cement slurries along with dispersants and retarders to achieve low fluid loss ranges and are compatible with other cement additive and all API oil well cement.
• Cement Extender/Density Reducer: Cement additives to reduce the Density of the cement system and increase the cement slurry yield and a compressive strength enhancer for low temperature light weight cements. 
• Cement Expander/Bond Improving Additive:  is an anti-shrinkage expansive additive which is added to the cement to cause expansion of the cement to help in creating a good cement bond to both the casing and the bore wall. Cement expansion Additives manufactured by GDFCL is used to expand the cement on setting and ensuring a strong band between the casing and the Bore -wall and reduce the undesired spread of the fluids in the Formation Zone.
• Anti-Foam/Foam Prevanter/Defoamer:  Cementing Additives to reduce the air entrapment and foaming of the cement slurry During Mixing. Cement Slurry Antifoam: These are additives that are added to the cement Slurry to reduce the foaming tendency of the Cement Slurry used as a preventive measure Cement Slurry Defoamer: These are additives that are added to the Cement Slurry after the formation of the Foam to Destroy the Foam.
• Cement Loss Circulations Materials: Additives to Prevent the loss of the cement slurry into the loss porous Formations. These additives added to cement slurry to maximize the chance of the stopping the losses. Cementing LCM additives manufactured by GDFCL is used to react, form a bridge and block fractures and prevent loss of cement slurry into less porous formations.
• Cementing Accelerators: Additives to reduce the setting time and increase the rate of Compressive strength, speeds up or shortens the normal rate of reaction time between cement and water which shortens the thickening time of the cement and increases the early strength of the cement required for the cement slurry to become hardened mass. Accelerators manufactured by GDFCL are used to counter the setting delay of other additives added to the slurry such as dispersants and fluid loss control agents.
• Spacers and Flushing Agents: are additives that are pumped between the drilling fluid and the cement slurry to form a buffer and prevent the drilling fluid and the cement slurry from coming into contact. Cement Spacers are effective displacement aids, because they separate incompatible fluids such as cement and drilling fluid and to assist and condition the walls of the wellbore for effective cement bonding.
• Cementing Anti Gas Migration/Gas Block Agent: Additives Designed for shale control and sealants in water-based mud systems and to impart fluid loss control and High Temperature Suspension properties improving dispersion and add stability to the cement slurry.
• Cement Anti Settling/Suspending Agent: Designed to hold cement and additives in suspension while cement is setting, it effectively prevents sedimentation and free fluid formation in cement slurries and is primarily used for cement stabilization.  
• Cement Weighting Agents: Designed to increase slurry density for control of highly pressured wells.
