Abstract: An aqueous slurry composition for use in industries such as the petroleum and pipeline industries includes a particulate, an aqueous liquid and a chemical compound that renders the particulate surface extremely hydrophobic. The slurry is produced by rendering the surface of the particulate extremely hydrophobic during or before making the slurry.

Abstract: Hydrocarbon fluid compositions comprising a liquid hydrocarbon, an aluminum soap, a hydrocarbon foaming agent and a gas. The fluids can be used in various oil field operations.

Abstract: A new hydrocarbon fluid composition and methods of using the fluid are disclosed. The fluid is comprised of a liquid hydrocarbon, a phosphate ester, an iron or aluminum salt crosslinker, a hydrocarbon foaming agent and a gas. The fluid can be used in many applications.

Abstract: The invention relates to surfactant based viscoelastic fluids for enhancing the productivity of a hydrocarbon-bearing formations, such as oil wells. The viscoelastic fluids of the invention have particular applicability in acid fracturing of subterranean formations surrounding oil and gas wells. The viscoelastic fluid contains an inorganic acid and at least one C10 to C24 alkyl trialkyl quaternary ammonium aromatic salt such as quaternary ammonium salicylate or phthalate. An anionic surfactant may also be present in the viscoelastic fluid. The addition of the C10 to C24 alkyl trialkyl quaternary ammonium aromatic salt to the inorganic acid causes gellation of the acid.

Abstract: Biodegradable foam compositions for oil field operations including drilling, hydraulic fracturing and wellbore cleanout are disclosed. The compositions comprise an aqueous liquid, an alkyl polyglucoside surfactant and a gas.

Abstract: A subterranean fracturing fluid, which is relatively harmless to both the environment and subterranean formations includes an amphoteric surfactant, specifically a betaine surfactant and an organic electrolyte or an alcohol in an aqueous medium. Depending upon the proportions of the ingredients, and fluid can be foamed.

Abstract: A method and a system of managing utility cost of an entity are disclosed. The method and system include the functionality of measuring utility usage of the entity during a defined time interval and obtaining unit utility pricing information that is established during the coincident time interval. The method and system also matches the utility usage in a defined time interval with the utility per unit price in the same time interval for the purpose of calculating the utility cost in that time interval as well as the running total of the utility cost. Specifically, the running total is the sum of the utility costs measured for each time interval over a number of time intervals occurring during the day. The method and system further include capabilities of affecting the utility consumption of the entity based on the utility cost as measured in an interval as well as the running total utility cost.
