PRODUCT DATA SHEET
POTASSIUM ACETATE Description
Potassium acetate is an alternative source of potassium ions to the more commonly used potassium chloride. It is principally used to formulate water based fluids where KCl cannot be used due to environmental restrictions on the use of chloride ions.
Properties
COMMON NAME Potassium acetate CHEMICAL FORMULA
CH3COOK
APPEARANCE Colourless to white crystalline powder
SOLUBILITY IN WATER @ 20°C
Completely
SPECIFIC GRAVITY 1.8 pH 7.5 - 8.5
ODOUR Odourless MELTING POINT 554 °F (290 °C)
Application
Potassium acetate is used as a source of potassium ions. These ions, being non hydrated and of the right size compete strongly for the interlayer sites of swelling clay minerals such as montmorillonite and illite, and drive out most of the naturally occurring calcium and sodium ions. This converts the swelling clays into more stable pseudo mica-type structures, thus stabilising the so called “gumbo’ shales.
Advantages
When used in as an inhibitor offers three forms of inhibition. (Cationic exchange, Osmotic pressure and prevention of pore pressure transmission).
Offers a inhibitive environment without the chlorides. Ideal for use in sensitive environmental areas.
Recommended Treatment
The concentration of potassium depends on the level of magnesium and on the estimated bottom hole temperature. The normal concentration would be 10.5 - 40.0 lb/bbl (30 – 114 kg/m3) or higher. Handling Recommendation
Consult MSDS before use and use personal protective equipment as advised.

ODOUR Mild
Application
NX-RM is used as a viscosifier in invert oil / synthetic base systems. NX-RM is designed to provide increased yield point and gel strengths with minimal plastic viscosity in invert oil / synthetic base systems. NX-RM may be used with any type of oil to obtain increased carrying capacity and improve the shear thinning and thixotropic characteristics of invert oil/Synthetic base systems. NX-RM Can be used to prepare newly blended oil/Synthetic muds at ambient temperatures, which will contain satisfactory yield point and gel structure values to support weight material until NX-GEL and or NX-GEL HT have fully yielded. NX-RM may be added to an existing oil mud to provide increased yield point and gel strengths for improved hole cleaning. NX-RM may be used to formulate high viscosity sweeps and may also be used to for spacer fluids where viscosified oil mud is needed to separate two fluids.
Advantages
NX-RM enhances the performance of organoclays under initial, low temperature mixing conditions resulting in improved yield point and gel structure.
Ideal as a rheological enhancer for new build load out muds, as CONFI-GEL/CONFI-GEL HT may not have fully yielded.
Additional of NX-RM to oil muds containing CONFI-GEL will cause the fluid to quickly develop increased gel structures and permit the oil mud to become thixotropic. NX-RM is not an oil-thickening agent, but performs by maximizing the thixotropy of fluids which contain organophilic clay.
NX-RM will aid in reducing HTHP fluid loss and improving emulsion stability.

NX-ZO is a high purity NX-ZO, sulphide scavenger. The extremely fine particle-size-distribution of NX-ZO provides a very large surface area for fast, efficient sulphide scavenging.
Properties
COMMON NAME NX-ZO CHEMICAL FORMULA
ZnO
APPEARANCE Powder SOLUBILITY IN WATER @ 20°C
Insoluble
SPECIFIC GRAVITY 5.6 COLOUR Off white
Application
NX-ZO material reacts with sulphides to form Zinc Sulphide, ZnS under normal operating conditions. This precipitate is an insoluble, inert, fine solid which remains harmlessly in the mud system or is removed by the solids control equipment. NX-ZO is effective at the pH levels found in drilling fluids. It is recommended that a pH above 11 be maintained whenever H2S is expected. This high alkalinity converts the dangerous H2S gas to less toxic disulphide (H2) and sulphide (S2-) ions. The alkaline pH >11 allows an extra margin of safety. NX-ZO should be added through the hopper.
Advantages
Effective oil based hydrogen sulphide scavenger - pilot test is recommended before treatment.
Recommended Treatment
The initial treatment of NX-ZO is usually 1 - 2 lb/bbl (2.85 - 5.7 kg/m ).Subsequent field treatments should
be based on approximately 1 lb/bbl (2.85 kg/m ) of NX-ZO per 600 mg/l of sulphides detected. Use a
Garrett Gas Train to accurately determine sulphide levels in the mud.
Limitations Local environmental rules may prevent the use of this product. Can flocculate some water base muds.
Handling Recommendation Consult MSDS before use and use personal protective equipment as advised.

PRODUCT DATA SHEET
NX-NANO SURF Description
NX-NANO SURF is a highly concentrated blend of surfactant, powerful water-wetting agents designed to effectively break and remove invert emulsion filter cake. It disperses mud cakes efficiently with low environmental impact, by changing the filtercake surface into water-wet condition. The nano phase mixture with few surfactants in NX-NANO SURF serve to both release the solids and mud residue from the downhole formation surfaces and release any oily residue blockage to minimise formation damage , facilitating removal from the near well-bore and water wet contact media by reducing the interfacial tension to ultra-low value.
Properties
COMMON NAME Nano Phase Surfactant
CHEMICAL FORMULA
Proprietary
APPEARANCE Liquid COLOUR Pale yellow fluid
SPECIFIC GRAVITY 0.99 – 1.07 FLASH POINT >150 °C
UK HQ VALUE Gold
Application
NX-NANO SURF is used to clean up wells from the exposed reservoir matrix prior to the start of production. It is intended to be used as a solution in freshwater or seawater and brine, and applied as a ‘spacer’ perforating fluid or as reservoir suspension fluids. It is also designed to disperse the solids into water phase and prevent re-deposition of oil-wet solids into the reservoir rock or other media surfaces. NX-NANO SURF does not contain either aromatic hydrocarbons or alkyl-phenol surfactant.
Advantages
NX-NANO SURF is a blend of nano phase surfactants and water-wetting agents that will effectively disperse the residues of drilling mud and other deposits into water wet condition for easy and effective removal as well as filtercake removal. NX-NANO SURF fluids can be mixed in certain heavy brines to provide the means for a weighted fluids. Recommended Treatment
NX-NANO SURF is recommended at levels of 5 - 35% v/v, in the main clean-up pill. And may also be used
successfully in High Vis pill to aid in the removal of heavy oily solids/debris in workover and open hole
completions.

NX-COR Description
NX-COR is an oil-soluble, slightly water dispersible, film-forming organic amine type corrosion inhibitor. It effectively protects the drill string by forming a tough, persistent film on metal surfaces. It is compatible with all types of water-base muds, both weighted and un-weighted. It is most applicable when severely corrosive conditions are anticipated e.g. when utilising air-drilling techniques, or in the presence of carbon dioxide or hydrogen sulphide gases.
Properties
APPEARANCE Liquid SOLUBILITY IN WATER @ 20°C
Dispersive
SPECIFIC GRAVITY 0.88 ± 0.05 FLASH POINT >150 °F (65 °C)
COLOUR Colourless liquid POUR POINT 0 °F (-18 °C)
Application
NX-COR is used especially as a corrosion inhibitor in water-based drilling fluid systems. It coats both the inside and outside of drill pipe.
Advantages
NX-COR provides excellent corrosion inhibition for the drill string tubular goods and downhole tools.
Compatible with all water based fluids. Mixes readily with all oil solvents allowing ease of application. Effective in low concentrations. Stable up to 350 °F (176 °C).
Recommended Treatment
NX-COR is typically blended in a non-aqueous fluid, base oil or other hydrocarbon, at a ratio of 14 gal (52 litres) of NX-COR per 2 bbl (0.32 m3) of non-aqueous fluid and is applied directly to the pipe to be protected by spraying onto the pipe. NX-COR can be used a pill for pumping inside the drillstring at a rate of 2 -3 gallons (7 – 11 litres) per 1000 ft (300m) of pipe. Monitor effectiveness by running corrosion coupons. If corrosion levels is too high increase frequency of treatment. Most effective if treatments are on the drill pipe directly and not via the mud system.

PRODUCT DATA SHEET
NX-PPD C100 Description
NX-PPD C100 is a concentrated pour point depressant , a product to reduce pour point and improve pumpability of a wide range of waxy crude oils, in distillates and residual fuel oils. At this temperature, most concentrated pour point depressants are solid thus ideal formulation is required for each crude oil characteristic. This product has shown an excellent performance in solid formation modification for improving flow. Crystal modifiers interfere with the normal crystal growth pattern and prevent the growth of insoluble deposits.
Properties
COMMON NAME Copolymer styrene CHEMICAL FORMULA
No data
APPEARANCE Colourless yellow liquid
SOLUBILITY IN WATER @ 20°C
Insoluble
SPECIFIC GRAVITY 0.90 – 0.95 FLASH POINT 110 – 140 °F (43 – 60 °C)
Application
NX-PPD C100 pour point depressant can be formulated into finished blends using heavy aromatic solvents. If winterization is required, toluene or xylene should be used. NX-PPD C100 can also be combined with paraffin solvents or paraffin dispersants to enhance the performance of the finished compounds. When formulations made from this product are used to inhibit paraffin crystallization or for pour point depression, continuous injection is recommended. The severity of the problem will dictate the dosage, but a typical rate would be 1 gallon of a typical dilution of this product to 500 barrels of produced oil. An initial slug of 5 to 10 gallons should be made prior to continuous injection.
Winterization properties of this product will depend on the solvents used for dilution. The pour point of finished blends can be adversely affected by heating/cooling cycles. If the sample is cooled from 60˚F to lower temperatures, it will be fluid at the published pour point. If the temperature is cycled or the product is exposed to cold temperatures for extended periods of time, gelling may occur at significantly higher temperatures. This gel can easily be broken by agitation or heating with no detrimental effect to the product or its performance. Heated storage to a minimum of 60˚F is recommended until the product is moved to the field for immediate use.
Advantages
Dilutions of NX-PPD C100 can also be effective in treating tank bottoms where paraffin has separated out of stored crude oil.
