Drilling Additives
Deflocculants Thinners and Dispersants

In water-based muds, as incorporation of drilled solids progressively influences the mud rheology, it may be of significant benefit to reduce the viscosity of drilling fluid using a thinning agent (deflocculant). These highly effective products avoid the need for mud dilution which also requires replenishment of mud chemicals and increases mud volume and disposal costs. In addition, once present, thinners will maintain a dispersed drilling fluid rheology, thus protecting against mud gelling or flocculation due to contamination and / or high temperature. This in turn will help achieve a thin filter-cake at the wellbore and will avoid excess fluid loss and associated issues.

Filtration Control Agents

Filtrate is the liquid portion of the mud system that is driven through a filter cake and into the formation by the differential between the hydrostatic pressure of the mud column and the formation pressure.

Shale Stabilizers

It stabilizers the shale formation, inhibits dispersion of drilled solids, improves lubricity and reduces torque & drag of the drilling string. It controls HTHP fluid loss by producing a thin strong compressible wall cake.

When encountering shale during drilling operations, water in the drilling fluid may interact with the clay materials within the formation, causing the shale to swell. This can lead to instability in the wellbore, and dispersion of shale into the drilling fluid (sloughing), eventually leading to hole washout.

Depending on specific needs, we have developed a range of shale inhibitors with differing molecular weights, ionicity, and product forms to cater to different conditions and fluid systems. The products range from hydration inhibitors to multifunctional polymers which give additional viscosity and carrying capacity.

Alternatively where such viscosity is not desired i.e., in low solids non-dispersed muds or in mud pre-mix concentrates, this effect is minimized but shale inhibition is maintained. This is achieved by controlling polymer molecular weight during the manufacturing process.

Lost-circulation materials

It is used to control and eliminate lost circulation due to fracures, broken formations. Lost-circulation materials can be broadly defined to include any material that seals or bridges against permeable or fractured formations to inhibit the loss of whole drilling fluid. An enormous variety of materials have been used to bridge, mat, and/or plug voids to combat loss of circulation. These materials can be divided into four categories: fibrous materials, flake materials, granular materials, and blends containing fibrous, flake, and granular materials.


Essential additives which establish the right carrying capacity to move cuttings and other debris away from the drill bit, help maintain the correct pressure in the borehole, and lower filtration. In addition, while mud circulation is stopped, e.g., to add drill-string, a flat gel strength is produced which maintains cuttings in suspension, avoiding blockage at the drill-bit.

We offer a range of viscosifiers varying molecular weight, ionicity, and product form to address different requirements

Weighting Agents

In water based and oil based mud weighting agents are used to control the density of the drilling fluids. Different materials as mentioned below are available from our end to suit the requirement of designing the drilling fluid within the density range required by the operations.

Biocides and Scavengers

In oil field biocides are used in production installation to control the microbial activities which is very essential to prevent the bacterial invasion of oil fields. Scavengers are used to control the H2S particularly in the off shore drilling operation. Zinc Carbonate is commonly used.

Oil Based Mud Products

Oil based muds are used where water based muds are difficult to control in terms of Rheology. Oil based mud generally consist of water in oil (oil can be diesel, synthetic oils etc.). These muds require special additives so as to emulsify water in oil along with the wetting agents and gelling agents etc. Our range of additives is mentioned below.

Drilling Mud Lubricants

These lubricants are the special typeof additives when mixed in drilling fluids impart lubricating properties into metal & metal to borehole contacts under extreme pressure conditions. These are specially used in directional & crooked holes, deeper holes and packed hole where frictional forces tend to be relatively high to reduce the loss of mechanical power
