ORGANOPHILIC CLAY-BASE THICKENERS by J. W. JORDAN Baroid Division, ~ational Lead Company, Houston, Texas ABSTRACT The clay minerals, generally characterized by their small particle size, affinity for water,
Organoclay is an organically modified phyllosilicate, derived from a naturally occurring clay mineral. By exchanging the original interlayer cations for organocations (typically quaternary alkylammonium ions) an organophilic surface is generated, consisting of covalently linked organic moieties.
The introduction of SBFs formulated with zero or minimal additions of organophilic clay and lignitic products allowed rheological and fluid-loss properties to be controlled through the fluid-emulsion characteristics. The performance advantages of these systems include:

Ranger Energy Services: Built for State-Of-The-Art Well Servicing. Upstream operations have changed tremendously over the last decade. Longer unconventional horizontals, more complexity and greater financial pressure are the new normal.
Specifically, Wiki tells me that bentonite clay is an adsorbent. They can help draw out sebum and whatever else is superficially in the pore. Some clays have antimicrobial and anti-inflammatory properties.
ERTEN ETAL., doi:10.1520/STP104214 33 observed, when the initial NAPL saturation of kaolinite was 28 % with a layer of organophilic clay on top.
The Actlabs Group of Companies provides contract analytical services covering all aspects of analysis from academic research applications to routine quality control functions.
Organophilic definition is - of, relating to, or having a strong affinity for organic compounds—used especially of colloids that swell and form solvates in organic liquids commonly used as solvents.
SE OPC Organophilic Clay . A very high quality organophilic clay additive for oil mud and invert drilling fluid systems. SE OPC offers several advantages including treating rates, attaining yield points quickly in high purity mineral oil systems and temperature enility; and excellent solids carrying capacity.
The introduction of SBFs formulated with zero or minimal additions of organophilic clay and lignitic products allowed rheological and fluid-loss properties to be controlled through the fluid-emulsion characteristics. The performance advantages of these systems include high, flat gel strengths that break with minimal initiation pressure; significantly lower equivalent circulating densities ...
Clay minerals whose surfaces have been coated with a chemical to make them oil-dispersible. Bentonite and hectorite (plate-like clays) and attapulgite and sepiolite (rod-shaped clays) are treated with oil-wetting agents during manufacturing and are used as oil-mud additives.
