    Clay Control IN DRILLING AND COMPLETIONC

    lay minerals, generally crystalline in nature, typically have a flaky structure. Clay flakes are made up of a number ofcrystal platelets stacked face-to-face in layers held in placeby weak attractive forces. Water invasion of clay depositscauses swelling, a process by which water molecules are

    adsorbed onto crystal surfaces and drawn by osmosis between thelayers of clay flakes, forcing them apart.

    Shale is a type of sedimentary rock composed chiefly of silt andclay. There are many different types bituminous shale, oil shale andgas shale all of which are important sources of fossil hydrocarbons.Clay swelling in shale formations during drilling or well completion can have a tremendously adverse impact on oil and gas operations.

    Traditionally, preventing clay swelling in oilfield operations by aque-ous liquids has been achieved using large concentrations of inorganicsalts, mainly potassium chloride (KCl). However, effective clay controlrequires high concentrations, which can be difficult to apply.

    Current methods of clay control involve both polymers and ammonium compounds. Polymers stabilize clays by reducing the rate of water penetration into the shale, while amines and ammoniumcompounds inhibit swelling by chemical means.

    One effective way to isolate clays from water inflow involves the use of water-soluble polyol compounds to achieve cloud point underdown-hole conditions. At temperatures above the cloud point, the precipitated polymer forms a barrier that not only protects the formationfrom water, but also reduces its fluid loss. The same polymeric additives act as lubricants and suspending agents for drill cuttings.

    Amines/quaternary compounds inhibit swelling by changing theionic strength and the transport behavior of fluids into clays, thus preventing clay platelets from moving further apart.

    In field operations, both types of inhibitors are often used in conjunction with minimal concentrations of KCl to provide maximumclay control. Fluid design compatible with formation minerals and othercomponents under site-specific work conditions is a key element ofsuccess.

    Huntsmans leadership position comes from its range of technologies, world-scale integrated manufacturing capabilities, and

    global distribution network.
