Abstract: Oilfield treatment compositions contain water, hydrochloric acid and urea. The urea and water may be present at a urea/water weight ratio between 0.8 and 12.0, and the hydrochloric acid and urea may be present at a urea/hydrochloric acid molar ratio between 0.1 and 0.5. The compositions are present as one liquid phase. The volumes of the compositions are substantially higher than those of the water volumes; consequently, the amount of water necessary to perform various well-service operations is lower.

Abstract: This method is designed to facilitate the well treatment with the possibilities for non-uniform/heterogeneous proppant placement in the extended and branched fractures produced by hydraulic fracturing.The essence of the method is to inject a proppant-bearing gel into the wellbore drilled into a productive formation. The low-viscosity fracturing fluid is injected into the wellbore together with the gel fluid (simultaneously or in turns). The method also provides for the injection of gas into the proppant-bearing gel and/or the low-viscosity fluid. The gas can be injected upstream of the junction point, at the junction point, or downstream of the junction point of the flows of the proppant-bearing gel and the low-viscosity fluid. The method further provides for the division of the gel fluid into the separate agglomerates with their subsequent injection into the fractures in the subterranean formation to form the proppant structures in the fracture.

Abstract: Oilfield treatment compositions contain water, hydrochloric acid at a concentration between 15 wt % and 45.7 wt % and a first fixing agent. The first fixing agent comprises urea, a urea derivative or both. The molar ratio between the first fixing agent and water may be higher than or equal to 0.5, and urea is the dominant solvent species in the compositions. In these compositions the first fixing agent provides corrosion inhibition when exposed to steel. The compositions may also contain a second fixing agent and an inhibitor aid.

Abstract: A technique facilitates a fracturing operation by maintaining the heterogeneity of proppant fluid as it is injected into reservoir fractures. The technique comprises using a blender to deliver proppant material in a pulsating manner to create pulses of proppant. The pulses of proppant are mixed with a fluid to create a proppant slurry having the pulses of proppant material separated by a second fluid. The proppant slurry is then split between a plurality of pumps which are operated to pump the slurry to a well. To maintain heterogeneity, the pump rates of the pumps are individually adjusted to control dispersion of the pulses of proppant downstream of the pumps and to substantially maintain the separated pulses of proppant material in the slurry. A wide variety of other system adjustments also may be made for enhancing the ability of the overall fracturing system to maintain separated pulses of concentrated proppant material.
