摘要： A method is described for treating a subterranean formation with a low viscosity fluid system that contains a viscoelastic surfactant at a concentration too low to viscosify the fluid, but that is concentrated in the formation so that the fluid system gels. The fluid optionally contains a formation-dissolving agent. The fluid is used in matrix acidizing, acid fracturing, and diversion.

摘要： Methods are given for making scale inhibitors, that were previously incompatible with fluids containing fluoride ion, compatible with fluids containing fluoride ion. Examples of such scale inhibitors include phosphonates and phosphino-polycarboxylates. The method is replacing alkali metal and alkaline earth metal cations, present in salts or bases, or as counter ions of the scale inhibitors, with hydrogen or ammonium ions. Methods of inhibiting scale formation and of dissolving scales are also given.

摘要： A treatment fluid for a subterranean formation includes a carrier fluid and an amount of particles including a granular scale inhibitor. The carrier fluid includes a hydratable gel fluid, a crosslinked gel fluid, an acid-based fluid, an oil-based fluid, and/or a visco-elastic surfactant. The particles include a proppant impregnated with the scale inhibitor, a solid particle formed largely from the scale inhibitor, or both. The proppant includes scale inhibitor adsorbed on porous surfaces within the proppant, and/or a porous proppant with scale inhibitor embedded in the bulk porosity of the proppant. The scale inhibitor is present in an amount between about 1% and 5% of a total weight of particles. The particles include scale inhibitor at a sufficient concentration and dissolution rate to provide acceptable scale inhibitor concentrations in produced fluids for production volumes exceeding 500 pore volumes.
