Abstract: A drilling fluid additive characterized by a drilling fluid viscosity regulating property which imparts a stable rheological profile to an oil based drilling fluid characterized by a substantially constant equivalent circulating density over a temperature range of about 120° F. to about 40° F. or a substantially constant high shear rate viscosity reading measured at 600 rpm. The present invention further provides an oil based drilling fluid including a continuous base oil phase; a weighting agent; a filtrate reducer; an emulsifier; and an effective amount of a rheological additive. The oil based drilling fluid exhibits a substantially constant equivalent circulating density and a substantially constant high shear rate viscosity reading over a temperature range of about 120° F. to about 40° F.

Abstract: A method to improve an efflorescence resistance of film forming compositions. The method comprises the step of adding a coalescent aid comprising a fatty acid ester to the film forming composition, the fatty acid ester has a formula of RCOOX wherein R is a hydrocarbyl having one or more aliphatic carbon-carbon double bonds, and X is selected from a group consisting of: a saturated hydrocarbyl, a hydrocarbyl having one or more aliphatic carbon-carbon double bonds and a substituted hydrocarbyl. These non volatile organic fatty acid ester based coalescents impart superior efflorescence resistance and resistance to color change to film forming compositions, including latex paints, versus conventional, VOC coalescent solvent.

Abstract: The invention is of oil-based drilling fluids including invert emulsion fluids that are able to maintain a relatively consistent rheological profile over a wide temperature range. The invention also includes new additives that enable the preparation of drilling fluids with viscosities that are less affected by temperature over a temperature range from less than about 40° F. to more than about 250° F. compared to conventional fluids. These additives are based on reaction products of polyamines and carboxylic acids with two or more carboxylic moieties combined with alkoxylated amines and fatty acid amides. In addition, this invention permits the use of reduced amounts of organoclay rheological additives in drilling fluids.

Abstract: A method for determining degree of organoclay delamination and degree of layer alignment in a polymer organoclay nanocomposite comprising one or more infrared light spectral measurements selected from the group consisting of (A) Si—O absorption bandwidth, (B) Si—O absorption band intensity, (C) Si—O absorption band area, and (D) Si—O absorption anisotropy.

Abstract: A clay slurry is described using smectite clay, water, and a defined phosphonate additive that is hydrolytically stable over time. The viscosity of the clay slurry remains pourable and relatively unchanged over time compared to prior art slurries. The slurry is useful to provide rheological control to paints and coatings and is particularly useful as an anti-bleed additive for concrete.

Abstract: This invention is of a hybrid organoclay that consists of an organic chemical/phyllosilicate clay intercalate that has been ion-exchanged with quaternary ammonium compounds. Since this hybrid organoclay is hydrophobic, it can be washed in water to remove reaction salts and excess water soluble or water dispersible polymers to give a clean product via inexpensive means such as filtration. This allows a better dispersing composition to be prepared without the difficulties of isolation presented by prior art which uses energy intensive means to remove the bulk of the water from the final product and cannot be easily washed. In one aspect, the present invention provides a solid clay/chemical composition that comprises: (a) one or more smectite clays, (b) a quaternary ammonium compound which reacts via an ion exchange mechanism with the smectite clay, and (c) one or more non-anionic organic materials that intercalate with the clay.

Abstract: This invention relates to aqueous-based oil well drilling fluids containing a starch polymer derived from a starch having an amylose content of at least 50% by weight. The starch polymers provide high temperature fluid loss performance while having a minimum impact on viscosity build when incorporated into well drilling fluids. They may also be used in other applications for which cellulosic polymers have heretofore been employed because of their high temperature tolerance and minimum impact on rheological properties compared to conventional starch polymers.

Abstract: The present invention is directed to polymer compositions with flame retardant properties that are made from a polymer blended using a defined process with a smectite clay that has been reacted with a specified mixture of organic materials. The inventive compositions have the property that when the organically modified clay is added to the polymer, a composite results which has flame-retardant properties and is based on the finding that degree of dispersion of a smectite organoclay in a polymer matrix will give the compositions flame-retardant properties. Further, it has been found that it is very important to proper functioning of the flame retardant polymer compositions that they have the organoclay dispersed in the polymer such that it is not completely exfoliated.

Abstract: The present invention is directed to a synthetic fuel made of coal dust, water and an organic chemical reactive with the coal dust to form a chemical bond with the coal dust upon compacting to provide a product very similar to coal. The inventive product surprisingly in some case provides higher BTU value than coal alone (up to 5 to 1000 BTU per ton more than counterpart coal), does not produce the waste ash at the users' facility of inorganic chemicals (and many organic chemicals such as tar) and can solve a moisture problem of coal dust and give even more increased green strength.
