Abstract: A method and system are provided for preparing a fracturing fluid for a fracture treatment in a subterranean formation using different types of fluids. A first mixture, formed with a consistent quality fluid and proppant, is combined with a second mixture, formed with an inconsistent quality fluid, to create a combined fracturing fluid. Each of the first and second mixtures may be pressurized and combined for use in one or more stages of a fracture treatment. The consistent quality fluid may comprise a new or high quality fluid and the inconsistent quality fluid may comprise a low quality fluid, such as fluid recovered or recycled from a previous fracturing treatment. Chemicals may be added to one or both mixtures. Quality measurements may be obtained for the second mixture. Independent monitoring and control of system allow for the preparation of a fracturing fluid with predetermined qualities.

Abstract: An apparatus and method for the treatment of stimulation fluid that involves passing a mixture of the stimulation fluid and reagents through a sectioned tank, each section having the means to agitate the mixture contained therein. Treated fluid is removed from a final settling section for reuse in oil and gas production operations.

Abstract: A method of acidizing and cleaning up a formation is disclosed, the formation being above 150 degrees C. The formation is treated with a mutual solvent system comprising a mutual solvent of oil and water, an aqueous acid, a corrosion inhibitor, and an iron control agent. In some embodiments, the iron control agent is present in an amount of less than 1% by weight of the mutual solvent system. In some embodiments, the corrosion inhibitor may be present in an amount of less than 10% by weight of the mutual solvent system. In some embodiments, the mutual solvent system further comprises an intensifier.

Abstract: A hydrocarbon well treatment fluid is made recyclable by introducing a laminar flow enhancer into the fluid, resulting in a formulation called Slick Oil™ hydrocarbon fluid. A method of using a fluid in the treatment of a hydrocarbon reservoir is disclosed. A hydrocarbon fluid is injected into the hydrocarbon reservoir, the hydrocarbon fluid comprising hydrocarbons and a hydrophobic laminar flow enhancer. The hydrocarbon fluid is recovered from the hydrocarbon reservoir. The recovered hydrocarbon fluid is then cleaned by removing contaminants from the recovered hydrocarbon fluid that have been introduced into the hydrocarbon fluid from the hydrocarbon reservoir. The hydrocarbon fluid is then re-used by injecting the cleaned and recovered hydrocarbon fluid into at least one subsequent hydrocarbon reservoir. Proppant carrying abilities of a hydrocarbon fracturing fluid are enhanced by introducing a laminar flow enhancer into the fluid, resulting in a formulation called Slick Oil™ hydrocarbon fluid.

Abstract: Hydrocarbon stimulation fluids are often used to increase the permeability and productivity of oil and gas reservoirs. The fluid itself is made up of a mixture of hydrocarbons and various chemicals designed to induce gel formation and gel breaking. The successful removal of these chemicals from the fluid has been achieved, through a process of acid-washing and filtration. This will allow the fluid to be re-used many times for further fracturing processes.
