The method for well-stimulation through a wellbore in a rock formation is hydraulic fracturing under high temperature conditions. The method includes injecting a fracturing fluid system to the rock formation; fracturing the rock formation at a temperature between 150-260 degrees Celsius; and recovering fluid components of the fracturing fluid system from the wellbore and setting the proppant in the fractures. The fracturing fluid system includes proppant and a plurality of fluid components. The fluid components can include water, a gelling agent, and a stabilizer made of ascorbic acid ranging from 50-100 ppt so as to adjust pH and delay said cross linking agent.

Methods and systems for treating a subterranean formation. The method comprises adding proppant particulates to a fluidized bed granulator; spraying a binding agent on the proppant particulates to at least partially coat the proppant particulates with the binding agent, wherein the coated proppant particulates form proto-aggregates; adding the proto-aggregates to a treatment fluid; and introducing the treatment fluid into a fracture within the subterranean formation.

Disclosed herein are compositions and methods for increasing recovery of hydrocarbon compounds from hydrocarbon-containing subterranean fractured rock formations. Novel emulsions and fracturing fluids are provided. The fracturing fluids convert oil-wet rocks to water-wet, yet exhibit a low tendency of composition components to sorb to the rock. The fracturing fluids do not cause formation of emulsions with hydrocarbon compounds within the subterranean fractured rock formations.

Provided herein include a degradation-promoted polymer and a method for making the degradation-promoted polymer. The degradation-promoted polymer has a composition containing one or more polymers and a degradation-promoting agent that includes Lactide and an organic acid. The organic acid may include at least one of succinic acid, levulinic acid, and lauric acid. The degradation-promoting agent can promote and control the degradation of the polymer in aqueous-based environments having different temperatures, pressures depths, and aqueous solutions. The method includes mixing a polymer with a degradation-promoting agent to produce a degradation-promoted polymer. Application for such degradation-promoted polymer can include but not limited to such as for example a process for opening new oil well, oil well work-over, or oil well cleanout, in which each well may have a different temperature and may require a different degradation rate of the polymer.
