Abstract: A pressure wave is generated within a first well extending into a subterranean formation. A pressure response associated with the pressure wave is detected from a second well extending into the formation. Information is then determined, based on the pressure response in the second well, wherein the information is associated with at least one of the formation and a fracture connected to at least one of the first well and the second well.

Abstract: A technique facilitates mixing of fluids for use in well treatment operations. According to an embodiment, a dry powder material, e.g. a friction reducer, may be thoroughly mixed into fluid or fluids associated with a well treatment operation. The powder material is combined with liquid, e.g. water, via a series of Venturi mixers arranged to thoroughly mix the materials. In some applications, the Venturi mixers are mounted on a modular unit which is readily moved to a desired wellsite. Additional modular units may be added to increase the amount of product being mixed according to the demands of a given well treatment operation, e.g. a hydraulic fracturing operation.

Abstract: Cement slurries are prepared that comprise water, a hydraulic cement and particles of an oil-absorbent material. The particles are present in an amount sufficient to alter a property of a non-aqueous drilling fluid. The cement slurry is placed in a subterranean well, whereupon the slurry contacts residual drilling fluid on casing and formation surfaces. The oil-absorbent material in the cement slurry may reduce the mobility of the drilling fluid, thereby improving zonal isolation.
