Pexovis 553

Pexovis 553 is a polymeric viscosifier for oil and synthetic based drilling muds, offering an engineered rheological profile to provide low ECDs at low concentrations with greater suspension properties and excellent hole cleaning. Pexovis 553 is suitable for use in drilling fluids at bottomhole temperatures up to 500 °F (260 °C). It is previously sold under the Viscodrill 12. Pexovis 553 increases low-shear-rate viscosities (LSRV) and gel strengths for improved hole cleaning in deviated wells

Potassium Sulfate

Potassium Sulfate is the potash fertilizer, composed of potassium and sulfur elements. This chemical compound is a water-soluble, non-flammable, odorless white crystalline salt having the formula K2SO4. Potassium chloride and sulfuric acid are the raw materials to make potassium sulfate.


SR-BIO is a non oxidize Biocide. For use in drilling mud to control bacterial slime contamination due to the presence of iron related and sulphate reducing bacterial.It is a combined liquid biocide and corrosion inhibitor for most water base systems.It is water soluble,oil dispersible.when biological growth occurs in fluid the organisams can be killed with a treatment of Biocide.As a pretreatment the product is used in drilling fluid which will be left in the hole for an extended period.SR-BIO exhibits extended biocidal action and corrosion protection in workover and packer fluid.It will prevent the biodegration of any polymer system.It is designed for use in workover and calcium chloride brines at the levels associated with normal drilling additives.If higher concentration brines,or brines using calcium bromide are to be used.It can be used in clean up well screens,pumps and distribution system.A concentration of 0.4 to 1.0 % of SR-BIO per volume of fluid will effectively control bacteria and corrosion and should be added to all workover,completion and packer fluids.

SR-DS is a highly-purity drilling starch in powder form. The product is cold-water soluble in all water-base drilling mud system. It is produced from potato and corn. –bases forms, depending on the customer’s specific requirement. SR-DS is used to control API Fluid loss in sea, saturated salt and polymer drilling muds. The normal concentration required rang between 2 and 6 ppb. the exact concentration on the desired Fluid control required.

SR-HENTROK is a specially manufactured product used to freeing differentially stuck pipe in a quick and easy manner. This highly effective soak solution has been proven numberous field applications to significantly and freeing struck pipe. SR-HENTROK when mixed with diesel or crude oil and placed in the zone of struck pipe,penetrates the cake between the wall and the pipe,release the differential pressure lock and provides a lubrication medium that enables the pipe to be pulled free when a non weighted spotting fluid can be safely used.Building a weighted spotting fluid requires additional material.

SR-KL is specially lignite material which has been carefully reacted with caustic potash.It is a fine dry powder easy to disperse in the drilling fluid. It is designed for use in potassium systems to control rheology and reduce fluid loss plus provide potassium for shale inhibition. It is compatible with all water base systems. It is highly soluble in normal pH muds and is stable at high drilling mud temperatures. It has good tolerance for soluble contaminants.SR-KL is designed for use in high muds and in potassium chloride polymer – dispersed systems. its primary function is fluid loss reduction and shale hydration. Approximately 2.0 7.0 ppb of SR-KL is recommended to achieve shale inhibition and water loss control.

SR-LIG is a naturally occurring material used to reduce fluid loss and deflocculates water base mud. SR-LIG is a partially soluble additive which provides thin, low permeability filter cakes. It is an excellent emulsifier for oil in water emulsions as wells a secondary deflocculated and is especially effective in high temperature applicatios.It performs exceptionally well in dispersed system as a synergistic additive with lignosulphonates.It can be used in virtually any water base fluid. Lignite powder may be use for rheology and filtration control in all water base muds.It is especially effective at stabilizing the properties of muds exposed to high temperature and contamination such as CO2 and calcium. SR-LIG is especially effective when treating cement contamination. It reduces the high viscosity and pH of cement contamination muds and reacts with calcium to lessen the contaminating effects. Normal treatment of SR-LIG range from 2.87 to 22.7 kg/m3.Due to their low pH, it’s treatment require additional caustic soda or an alternative alkaline material to maintain a consistent pH. A normal ratio is 1 sack of caustic soda for every 4sachs of SR-LIG. In high salinity systems. it is preferable to premix the SR-LIG in medium pH fresh water to enhance dispersibility then add the premix to the active system. It is most effective in mud systems with an alkaline pH in the range of 8 to 10.

SR-MOLDSIN is a polymer for core drilling, water well drilling, oil and seismic shot hole drilling. Lower solids drilling fluids based on polymer viscosifiers have been successfully used for many years, and their effectiveness in increasing drilling rates are well documented. SR-MOLDSIN effectively reduces the API filtration rate of many water-based oil and gas drilling fluids and may also be used to increase and stabilize viscosity to improve hole cleaning and suspension properties in a wide variety of fluid environments. Because ti is effective at low concentrations, It’s regular provides a cost-effective means of improving drilling fluid performance. In many drilling operations XC polymer are normally used to viscosify drilling fluids applied for drilling section between 500/1000 m – 2500/3000m. However expensive XC polymers are not required, as long as drilling is not carried out in horizontal holes or in pay zones where thixotropic drilling fluids are preferred.

SR-RXL is a fine black powder with brown tinge. It is a water soluble, thermally stable synthetic lignite derivative used to achieve filtration control and rheological stability over a wide range of temperature. It can tolerate wide range of soluble contamination. It is additive for all water base drilling fluids with chlorides below 60000 mg/L and hardness not exceeding,3500mg/L. Resinex lignite is formed by the reaction of sulphonated lignite and water soluble resin. It is resin lignite will reduce high temperature fluid loss and stabilize the muds at down hole stability. SR-RXL filtration agent should be used at concentration of 2 to 6 lb/bbl for fluid loss achive optimum solubility the pH should be adjusted above 9.5. Higher density fluid will require greater concentrations of SR-RXL additive. For increase bottomhole temperatures use larger concentrations depending on drilling conditions.
