Abstract: The invention of this application is a dispersant system with various embodiments and subcombinations with exceptional dispersions including colloidal suspensions, aqueous hydrocarbon emulsions and emulsions with solid particulate additives dispersed therein. The basic dispersant system which makes the high stability, high weight dispersions or emulsions possible comprises an emulsifier composition containing a fatty acid amide, oleic acid, dimerized oleic acid and a particular type of surfactant dispersant. For certain applications the following optional components can be used: particulate filler or carrier; a hydrocarbon phase which can be either liquid or a colloidal solid; water soluble salts weighting agents; insoluble salts and conventional additives.

Abstract: A treating process is provided for increasing the stability and resistance to degradation of naturally or artificially consolidated, permeable masses such as earthen formations or subterranean formations having exposed siliceous surfaces which are contacted by aqueous media. The treatment is effected by contacting the porous mass with a particular type of organosilicon compound which has a hydrophobic functional group and a silica bonding functional group to form a hydrophobic film on the exposed surfaces.

Abstract: An epoxy resin composition curable to a hard impermeable solid which contains a liquid aromatic diluent having the general formula:C.sub.6 (R.sub.1).sub.6wherein R.sub.1 is hydrogen; a straight or branched chain alkyl radical; a cycloparaffin radical or a mixture thereof; wherein the alkyl and cycloparaffin radicals have within the range of about 1 to 10 carbon atoms; and further wherein at least one R.sub.1 group is said alkyl or cycloparaffin radical.

Abstract: An improved method and composition for consolidating a porous and permeable subterranean particulated formation into a high strength water resistant mass is provided by a particular combination of vinyl monomers, catalyst system and optional features such as solvent, particulate filler, chelates and binders.

Abstract: The friction created by rotating and reciprocating a drill pipe in a well penetrating a subterranean formation is reduced by including an ester of an oxazolidine derivative in an aqueous drilling fluid or a mixture of said ester and certain alcohols. This ester of an oxazolidine derivative is represented by the following general formula: ##STR1## wherein n is a whole integer within the range of about 5 to 20.

Abstract: This invention relates to methods and additives for scavenging oxygen dissolved and entrained in liquids which are particularly suitable for removing dissolved and entrained oxygen from polymer-containing fluids used in drilling and completing well bores as well as water flood and other procedures carried out in the oil field. The oxygen scavenger additive is sodium dithionite or a mixture thereof with sodium dithionate dispersed in a liquid carrier such as a hydrocarbon.

Abstract: Oil well cementing compositions and processes are produced using a high efficiency sulfoalkylated lignin retarder composition and modifications thereof to produce cement compositions without gelation problems, having high early strength and with precisely controllable setting time.

Abstract: Methods of consolidating incompetent subterranean formations are provided whereby aqueous treating solutions are utilized to condition the formation, to carry a hardenable organic consolidating fluid into the formation and/or to carry particulated solids coated with a hardenable organic consolidating fluid into the formation and to cause the organic consolidating fluid to harden whereby a hard permeable mass is formed in the formation which prevents the undesirable movement of loose or incompetent sands therein.

Abstract: The invention of this application relates to the production and transportation of hydrocarbons which are initially or normally in the gaseous state. Specifically, the invention provides processes and an apparatus for drying or removing water vapor and condensable hydrocarbons and other condensable components from the natural gas stream.

Abstract: The present invention relates to novel lightweight cellular cement compositions, methods of preparing such compositions and methods of casting the compositions into lightweight high strength structural members.

Abstract: The present invention relates to a method of forming a highly permeable solid mass in a subterranean formation wherein a mixture of particulated solids and a resin composition are deposited in the formation and consolidated into a hard permeable mass, the particulated solids including soluble solids.

Abstract: An epoxy resin composition curable to a hard impermeable solid which contains a liquid aromatic diluent having the general formula:C.sub.6 (R.sub.1).sub.6wherein R.sub.1 is hydrogen; a straight or branched chain alkyl radical; a cycloparaffin radical or a mixture thereof; wherein the alkyl and cycloparaffin radicals have within the range of about 1 to 10 carbon atoms; and further wherein at least one R.sub.1 group is said alkyl or cycloparaffin radical.

Abstract: A thixotropic cementing composition for use in oil and gas wells comprises a hydraulic cement slurry including as an additive a complex reaction product of a water soluble carboxyalkyl, hydroxyalkyl or mixed carboxyalkyl hydroxyalkyl ether of cellulose, and a polyvalent metal salt, for example a reaction product of hydroxyethylcellulose and zirconyl chloride.
