Abstract: The present invention relates to a multistage centrifugal pump design, which has the diffusers, impellors, and a shaft, inserted within a high pressure housing, such that this assembly is fully enclosed within the housing, and the housing is of sufficient strength to be suitable for safe pressure containment of the fluids being pumped. This invention describes the technical details used to reconfigure the multistage centrifugal pump design to increase the discharge pressure capabilities higher than the 6,000 psig of current designs.

Abstract: A method or process for hydraulically fracturing an underground hydrocarbon deposit includes using as a source of water an underground aquifer which contains water which is stable and clear in the aquifer but which may include undesirable chemical compounds as soluble components that are not in solution when subjected to reduced pressure at atmospheric conditions. Water from the aquifer is used as a source of water for the hydrocarbon fracturing process. The water is pumped at a pressure above its bubble point pressure A source well and a disposal well are drilled into the aquifer. A pump capable of maintaining the water above its bubble point pressure is provided, and a closed loop is established with a manifold, or a manifold and pumps, to keep the aquifer water circulating at a pressure above its bubble point pressure. The hydrocarbon reserve is fractured using the water.

Abstract: Method of fracturing, hydrocarbon deposits comprising using as source of water an aquifer containing water stable and clear in the aquifer but which may include undesirable soluble chemical compounds that are not in solution when subjected to reduced pressures at surface conditions such as hydrogen sulfide, utilizing aquifer source water in a fracturing process to pump water under pressure at above the water's bubble point pressure to prevent undesirable constituents thereof from separating, maintaining said pressure at a minimum at all times during fracturing, drilling a source and disposal well to/from the aquifer, providing a pump capable of maintaining the minimum pressure, establishing a closed loop, to keep the aquifer water circulating at all times and the undesirable constituents remaining in solution and the water remaining clear thereby avoiding the necessity of treating the water from the aquifer prior to using it in a fracturing processes.

Abstract: A variable frequency power system with a power source having a rotating output and a speed control to regulate rotational speed of the rotating output. A generator coupled to and driven by the rotating output of the power source, whereby the speed control of the power source directly controls output power frequency of the generator due to control of rotational frequency of the rotating output. A voltage regulator connected between the generator and the motor regulates output voltage from the generator to the electrical motor load. A system controller controls output power frequency of the generator. The system controller interfaces with the speed control of the power source and configured to monitor generator output and operational conditions of the electrical motor load. The system controller adjusts the speed control based on generator output and operational conditions of the electrical motor load.
