    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.

    Packaging

    Potassium acetate is packaged in 25, 50 kg (55 and 100 lb) sacks and 1.0 MT Bulk Bags. Store in tightly closed containers, in a cool, dry, well-ventilated area.

    PRODUCT DATA SHEET

    POTASSIUM SULPHATE Description

    Potassium Sulphate is an alternative source of potassium ions to 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 e.g. land discharge of cuttings.

    Properties

    COMMON NAME Potassium sulphate CHEMICAL FORMULA

    K2SO4

    APPEARANCE Hygroscopic crystals SOLUBILITY IN WATER @ 20°C

    11.1g / 100 ml

    SPECIFIC GRAVITY 2.6 -2.7

    Application

    Potassium Sulphate is used as a source of potassium ions where a chloride free fluid is required in order to meet environmental discharge and disposal regulations.

    Advantages

    Tried and tested alternative to potassium chloride. Offers a inhibitive environment without the chlorides. Ideal for use in sensitive environmental area.

    Recommended Treatment

    The concentration of potassium depends on the level of magnesium and on the estimated bottom hole temperature. Concentrations range from 10.5 - 38 lb/bbl (30 – 108 kg/m3).

    Limitation

    Cannot be used in fluids containing high calcium and magnesium as it precipitates these ions. The maximum quantity of Potassium Sulphate that can be used is 10%, 38 b/bbl (108 kg/m3).

    Handling Recommendation

    Consult MSDS before use and use personal protective equipment as advised.

    PRODUCT DATA SHEET

    CALCIUM CHLORIDE Description

    Calcium chloride, CaCI2 is used as a completion, workover, gravel packing, perforating and packer fluid. It is also used as an osmotic generator in non-aqueous systems. It is available in a variety of purities varying from 74 – 95+ %.

    Properties

    COMMON NAME Clacium Chloride CHEMICAL FORMULA

    Proprietary

    APPEARANCE Powder SOLUBILITY IN WATER @ 20°C

    74.5g/100ml

    SPECIFIC GRAVITY 2.15

    Application

    The amount of Calcium chloride added to the mud is dependent on the water activity and or density of the fluid that is required.

    Advantages

    Readily available. High purity product. Economically viable. Common oil field usage.

    Recommended Treatment

    As a brine Calcium chloride can be used to formulate single salt brine to 11.67 lb/gal (1398 kg/m3) or in combination with other salts to form brines of the required density. The most common combination is with Calcium Bromide brines to densities up to 15.1 lb/gal (1812 kg/m3). For details of concentrations required check brine tables. In non- aqueous fluids, treatments will depend on the required degree of osmotic activity required. Limitation

    The use of Calcium chloride may be restricted by local HSE rules. If combined with monovalent salts it may cause precipitation in solution. Compatibility with work over chemicals should be confirmed prior to use. Compatibility with various rubber drilling components should be confirmed prior to contact. The crystallisation point of brines must be careful
