STALWOL CPG

Cloud Point Glycols

This additive is a low toxic, versatile cloud point glycols for shale control designed for low to high salinity water level system and can be used in well with low, moderate and high formation temperature in isolation or in combination with salts and polyamines.

STALWOL SS

Shale Stabilizers

This additive is an amine based shale inhibitor which are formulated to stabiIize reactive shales & clays while drilling with water based drilling fluids. These products are highly effective in inhibiting clay swelling and hydration of cuttings preventing bit balling and reducing torque and drag.

STALWOL ROP-E

ROP Enhancers

This additive is a low toxic, versatile, ROP Enhancer designed for medium-to-high salinity water level system and can be used in wells with moderate formation temperature. It can provide improved well bore stability, lubricity, high temperature filtration control, plus reduced dilution rates and bit balling. In a non-dispersed polymer system, it is most effective when used in conjunction with inhibitive salts like KCI.

STALWOL EPL

Extreme Pressure Lubricants

This additive is a general and special purpose extreme pressure lubricants which are used to reduce the torque, drag & possibility of wall sticking. These lubricants finds their application in highly deviated well bores,where a tough lubricating film is needed between the wall cake and drill string.

STALWOL AF

Defoamers/Antifoam

An effective way to disrupt foam formation is to introduce a foam control surfactant into the system. A defoamer or antifoamer functions by spreading over the gas/liquid interfaces, thereby preventing foam forming materials from coming to the surface and providing a surface layer which will not sustain foam.

STALWOL DD

Drilling Detergents

This additive is used to reduce the surface tension of water based mud systems and the sticking tendency of water sensitive formulations.

STALWOL HS

H2S Scavengers

This ties up with the H2S in an irreversible reaction preventing the release and thus reduces corrosion leading to improved safety. These products are designed to control H2S with bubble tower applications and/or continuous injections into the wellhead, infield or other transmission lines.

STALWOL SI

H2S Scavengers with scale inhibitor

This product is formulated lo give excellent H2S Scavenging characteristics with scale inhibition. It features an instantaneous reaction with hydrogen sulfide and is very effective even allow dosage rates. It effectively controls the scaling problem without any negative impact on downstream operations.

STALWOL PE

Emulsifiers for oil based mud

PRIMARY EMULSIFIER

This additive is used to produce a highly stable invert emulsion fluid with excellent emulsion stability, filtration control and temperature stability.

STALWOL SE

Emulsifiers for oil based mud

SECONDARY EMULSIFIER

This additive is a multi functional which provide higher stability to primary emulsifier & imparts preferential wetting of solids by the continuous oil phase.

STALWOL EU

Emulsifiers for oil based mud

EMULSIFIER ULTRA

It provides good and stable emulsification imparts sufficient oil wetting characteristics of solids and high tolerance for contaminants. The product also works well with all of the commonly used internal phase salt solutions.

STALWOL WA

Wetting Agents

This additive can quickly change the natural water-wetting characteristics of drilled solids and weighting agents in oil muds,making them preferentially oil-wetting. They are used as supplementary oilmud additive for improving fluid loss properties and emulsion stability.

STALWOL PFA

Pipe Freeing Agents

This additive is a specifically designed to assist in freeing stuck pipes. It lubricates and dehydrates filter cake from water-based fluids to aid in creating cracks in the mud cake to help alleviate differentially stuck drill pipes.

STALWOL DF

Defocculants

This additive is an anionic acrylic co-polymer used in water-based mud systems to control rheological properties and to impart high temperature stabiIity.

STALWOL EIE

Emulsifier for Invert Emulsions

This additive provides excellent waler-in-oil emulsion especially wilh high water percentage and high electrolyle concentration. These can be used along wilh primary and secondary emulsifiers.

STALWOL SSF

Surfactant for spacer fluids

This additive is a specially surfactant used in formulation of spacers used before cementing of oil wells drilled with oil based muds. It is designed to clean up and displace oil and synthetic based muds and solids for better cementation.

STALWOL SFA

Stable Foaming Agents

This additive is a surface active product and generates stable micro bubbles in presence of air to develop specific gravity as low as below 0.8. It is a waler based drilling fluid.

STALWOL LRA

Loss Reducing Agents

This is an advanced polymer based HTHP fluid loss reducing agent/ additive , meant for high performance water based drilling fluid systems. It is available in solid as well as in liquid forms. It is designed to be stable upto 225°C.

STALWOL BAC

Biocide

This is a Benzalkonium Chloride based Microbiocide and is used for effective control of aerobic and anaerobic bacteria in the oilfields as well as in various other applications. It prevents formation of sulphurous gases and inhibits corrosion and biofouling in pipelines.
