Abstract: The invention relates to a method for stabilizing a detonable mixture of emulsion and AN or ANFO prills and to the resulting compositions. A surfactant is dissolved in a liquid organic fuel prior to adding the fuel to AN prills for forming ANFO prills, or if AN prills are used without added liquid organic fuel, the surfactant is added to the prills. The ANFO prills or AN prills containing a surfactant than are mixed with the emulsion.

Abstract: Water-in-oil emulsion explosive compositions have improved detonation properties, stability and lower viscosity. Bis (alkanolamine or polyol) amide and/or ester derivatives of bis-carboxylated or anhydride derivatized addition polymers are used as the emulsifier. For example, alkanolamine reacted (2:1 ratio) with polyisobutenyl succinic anhydride is found superior to the corresponding 1:1 derivative.

Abstract: The present invention relates to an improved explosive composition. More particularly, the invention relates to a water-in-oil emulsion explosive having improved stability and a lower viscosity. The term "water-in-oil" means a dispersion of droplets of an aqueous solution or water-miscible melt (the discontinuous phase) in an oil or water-immiscible organic substance (the continuous phase). The term "explosive" means both cap-sensitive explosives and noncap-sensitive explosives commonly referred to as blasting agents. The water-in-oil emulsion explosives of this invention contain a water-immiscible organic fuel as the continuous phase and an emulsified inorganic oxidizer salt solution or melt as the discontinuous phase. (The terms "solution" or "melt" hereafter shall be used interchangeably.) These oxidizer and fuel phases react with one another upon initiation by a blasting cap and/or a booster to produce an effective detonation.

Abstract: The invention relates to a water-in-oil emulsion explosive comprising a water-immiscible organic fuel as a continuous phase; an emulsified aqueous inorganic oxidizer salt solution as a discontinuous phase; and a phenolic derivative of polypropene or polybutene as an emulsifier.

Abstract: A well bore cementing composition and method are shown in which a hydraulic cement, water and fluid loss additive are combined to form a cementing slurry. The fluid loss additive is a copolymer of a first monomer of dimethyl-diallyl ammonium chloride and a second anionic monomer. The monomer ratio of the non-ionic, water soluble monomer to the anionic monomer is in the range from about 85:15 to 95:5, and the copolymer has a molecular weight in the range from about 200,000 to 400,000.

Abstract: A well bore cementing composition and method are shown in which a hydraulic cement, water and a non-retarding fluid loss additive are combined to form a cementing slurry. The non-retarding fluid loss additive is a copolymer of a first non-ionic water soluble monomer which resists hydrolyzing in a cement slurry and a second anionic monomer. The monomer ratio of the non-ionic, water soluble monomer to the anionic monomer is in the range from about 85:15 to 95:5, and the copolymer has a molecular weight in the range from about 200,000 to 400,000.

Abstract: An aqueous cement composition is shown for cementing the annular space between a pipe and the surrounding bore in a well. The cement composition includes a hydraulic cement, water present in an amount effective to produce a pumpable slurry, a polyamine fluid loss additive, and a sulfonated polymer. By neutralizing the polyamine to a pH of approximately 7, improved free water and fluid loss properties are imparted to the system.

Abstract: A fluid loss additive and method are shown for use in cementing oil and gas well bores which comprises the reaction product of a polyamine compound and a high molecular weight sulfonated polymer. The polyamine and high molecular weight sulfonated polymer are prereacted in solution and dried to form a dry product which can be added to the dry cement blend on the shelf or added to the mixing water during the formation of the cement slurry at the well site. The prereacted additive is effective to control fluid loss in cement slurries at 350.degree. F. and higher.
