Title: ACIDIZING AND PROPPANT TRANSPORT WITH EMULSIFIED FLUID
Abstract:
Methods and compositions for stimulating oil or gas production from a well with a single treatment fluid for use in a combined acidizing and hydraulic fracturing treatment are provided. An embodiment is a method comprising: coating a plurality of proppant particulates with oil to form oil-coated proppant particulates; adding the oil-coated proppant particulates to a solution comprising water, an acid source, and an emulsifier, wherein the ratio of the oil coating the proppant particulates to the water in the solution is less than 20:80 by volume; and mixing the solution and the oil-coated proppant particulates to form a treatment fluid comprising a water-in- oil emulsion and the oil-coated proppant particulates.
