Through our products and services, we help optimize drilling and completion processes to maximize hydrocarbon production and manage drilling waste.

Leading technologies include environmentally compliant water-based and synthetic-based mud systems and remediation fluids that can restore productivity from damaged and non-producing wells.

Our advanced suite of water-based drilling fluids is effective in numerous applications, including:

System Trade Name	System Application
Crystal Chemicals-CAL	Calcium chloride/polymer-based system for maximum inhibition in highly reactive shales
DRILSMOOTH	DRILSMOOTH is a Mixed Metal Oxide (MMO) rheological modifier and secondary shale stabilizer designed to give improved carrying capacity and suspending ability in bentonite-based water base drilling fluids. It has application in drilling of lost circulation zones, high-angle and horizontal wells, and also for milling operations.
Crystal Chemicals-THERM DRILL	High Temperature High Pressure System The Crystal Chemicals-THERM DRILL system is an extremely flexible drilling fluid system used when temperature, contaminants, and/or borehole instability make conventional systems impractical or uneconomical. The actual composition will vary depending on specific requirements. Crystal Chemicals-THERM DRILL system is stable to > 230°C (450°F). The use of the Crystal Chemicals-THERM DRILL system allows for the conversion of conventional mud systems to an Crystal Chemicals-THERM DRILL HTHP drilling fluid without the need for complete displacement.
Crystal Chemicals-POLY TEMP	The Crystal Chemicals-POLY TEMP mud system uses POLY TEMP, a vinyl sulphonate-vinyl amide co-polymer of low to medium molecular weight, to reduce filtrate. Bentonite is used for suspension. POLY TEMP can be used in a seawater or freshwater system. Crystal Chemicals-POLY TEMP, a resin compound, is used to aid in HTHP filtrate control. The mud system has been reported to be stable with bottom hole temperatures up to 400F.
Crystal Chemicals-DRILL IN	A water-base reservoir drill-in fluid system that can be easily formulated to specific applications where completion compatibility and minimal formation damage are critical factors. The system is custom designed for each individual reservoir and uses a range of high-quality components.
Crystal Chemicals-GLY DRILL	Inhibitive Engineered Cloud Point Glycol System, the key evolutionary enhancement of the system is that it contains low molecular weight polyols. Polyols is the generic name for a wide range of chemicals, including glycerol, polyglycerol, polyethylene glycols, polypropylene glycol, polyalkylene glycols and alcohol ethoxylates. These chemicals are water soluble and nontoxic, passing existing environmental protocols worldwide.
Crystal Chemicals-BOND DRILL	Polymer-base, PHPA system for improved cuttings encapsulation and shale stabilization
Crystal Chemicals-CHROME DRILL	High-temperature, deflocculated system for general use (chrome-free available)
Crystal Chemicals- EASYDRILL	Advanced water-base drilling fluid with performance approaching oil-based mud. The system is based on multiple inhibitions approach where polyamine is the key component
Crystal Chemicals-ADVERT	ADVERT Diesel-based invert emulsion System provides excellent borehole le stability and lubricity, minimum corrosion, and in many cases, improved rate of penetration
Crystal Chemicals-ADVERT Plus	ADVERT Plus systems are the latest generation of Synthetic and Enhanced Mineral oil-based invert emulsion fluids designed to meet the regional environmental regulations.
Crystal Chemicals-SIL DRILL	Silicate-base system for drilling water-sensitive formations. The main application for silicate fluids is the replacement of oil and synthetic fluids in difficult drilling applications such as wells containing reactive claystones. Silicate fluids exhibit a very high degree of shale inhibition approaching invert emulsion fluids.
Crystal Chemicals-Clay Free Invert	Orange clay-free Invert mud drilling fluid system is built around a technology that provides significant benefits over the traditional invert emulsion-based fluids currently used. Orange clay-free oil base drilling fluid (OBF), an innovative oil base drilling fluid system, has the unique rheologic property of “fragile gel”, higher rate of penetration, stronger water resistance, thinner filter cake and much higher permeability recovery than traditional invert emulsion drilling fluid Compared with conventional invert emulsion fluids, clay-free Invert system can build a quick, high, yet fragile, low shear gel strengths to help eliminate barite sag. The rheology of these fluids is managed through the application of several innovative emulsifiers and fatty acids as well as the omission of commonly used organic lignite and clays to provide a robust, yet fragile gel structure. The most important additives in this system are emulsifier, fluid loss control agent, rheology modifier and viscosifier.
TriMAX	The TriMAX™ system is a synthetic based fluid that is engineered for deepwater environments where a wide range of formation types is anticipated. The fluid product concentrations are to be maintained to ensure minimize ECD downhole, provide inhibition against reactive shales and possible stuck pipe issues. It can be formulated as a flat rheology profile or as a Low ECD system with the same products in both formulations.

Completion Fluids

A workover or completion fluid is used to conduct a workover and/or completion operation. Crystal Chemicals Fluid selection based on consideration of the formation characteristics for a particular well. The fluid will be able to control wellbore pressures, as well as be non-damaging to the production interval. Because an over-balanced fluid column exists in most wells during completion and workover operations, fluid selection is critical if formation damage is to be minimized. Non-damaging fluids can be solids free, clay free, acid soluble, water soluble or oil soluble and are used for operations such as: drilling-in, perforating, cleaning out sanded wells, gravel packing, packer fluids, under reaming and well control. While the costs of these fluids are initially high, they are economically justified by the reduction in the time spent remedying or stimulating a production zone, and by the higher production rates attained by using a fluid that is compatible with the formation.

Crystal Chemicals offers a range of completion technologies including a completion and reservoir drill-in fluids, additives, and filtration and associated engineering services. Crystal Chemicals advanced the engineering of completion fluids and associated technologies that accelerate and maximize production with minimal health, safety, and environment (HSE) impact as our target to provide a cost-effective solution for optimizing productivity throughout the drilling, workover, and completion processes.

Our planning, design, execution, and monitoring process ensure minimal formation damage that could restrict production.

Crystal Chemicals completion focuses on total reservoir management to provide our customer with the following:
