Abstract: A preferred embodiment of the inventive fluid delivery system comprises a vertical liquid/vapor separator and riser assembly that comprises a multi-phase separator inlet, a vapor outlet and riser, and a liquid outlet port connected to a hydraulically-driven centrifugal pump. By controlling the operational speed of the pump, the level of the separated liquid within the separator can be controlled without the need for control valves. The vertical separator is capable of low pressure operation and large variations in controlled liquid levels within the separator, allowing the relatively slow reaction time pump to control the liquid level from low pressure wells penetrating low pressure reservoirs.

Abstract: A method for continuously acidizing a geological rock formation for at least 3 months comprising adding a dilute acid to a geothermal carrier fluid in a concentration less than 0.1 weight percent to produce an acidified fluid and continuously contacting the rock formation with the acidified fluid until the permeability of the formation is increased.

Abstract: A polymer concrete pipe liner is formed from a fluidized, but substantially waterless cement containing mixture applied to the pipe interior. The mixture is composed of inorganic cement particles, a liquid styrene mixture and a minor amount of one or more poly-olefinically unsaturated co-monomers. The mixture substantially excludes acrylonitrile and acrylamide. The co-monomers are preferable selected from a group including trimethylolpropane-trimethacrylate, divinyl benzene, hexadiene, and polyvinylsiloxanes. Mixing the liquid and solid components forms a slurry which is transferred to a pipe interior. Transfer properties can be controlled by particulate gradation, dissolved polymers, and rheology control additives. The pipe is then spun to centrifugally cast the liner. The composition avoids the need for high temperature curing and toxic reactive unsaturates to co-polymerize and cross-link polystyrene.

Abstract: A crystalline, galliosilicate molecular sieve having the mordenite structure and the following composition expressed in terms of oxide mole ratios in the anhydrous state:Ga.sub.2 O.sub.3 :xSiO.sub.2 :yM.sub.2 O:tQ.sub.2 Owhere M is an alkali metal, preferably sodium, Q is a quaternary ammonium cation, preferably a benzyltriethylammonium cation, x equals 5.0 to 30, y equals 0.1 to 0.99, preferably 0.40 to 0.90, t equals 0.01 to 0.9, preferably 0.1 to 0.6 and yet equals about 1.0. The crystalline, galliosilicate molecular sieve of the invention may be employed, after reducing its alkali metal content and decomposing Q, as a component of a catalyst which can be used in a variety of chemical conversion processes.

Abstract: A composition for use in enhanced oil recovery procedures comprises steam, carbon dioxide, carbonic acid, and a corrosion inhibitor. In one version of the invention, the corrosion inhibitor is a carbonate-containing buffering agent and in another version of the invention, the corrosion inhibitor is a pH-adjusting agent.
