Abstract
This paper investigates an approach to modifying conventional guar-borate systems by introducing binary thermochemical reagents that provide controlled activation of an exothermic reaction directly under reservoir conditions. A key aspect is the induction of an in situ process that combines thermal decomposition of the polymer matrix, pressure generation, and a gas-drive effect, aimed at the complete degradation of the gel into a Newtonian fluid with a viscosity of ~1.1 mPa·s.
Laboratory studies confirmed that the developed composition maintains stable rheological properties during the injection stage (crosslinked gel viscosity >500 cP at 100 s⁻¹), while subsequent activation by an acid agent ensures a rapid temperature increase to 73–83 °C and complete gel degradation. It was established that using surfactants within the activator composition enables the generation of stable foam systems with a quality of up to 25, which facilitates the mechanical displacement of degradation products from the pore space.
It is shown that secondary, yet significant, effects of the technology include the cleanup of formation damage (clays, mud) and the creation of thermal conditions for the consolidation of resin-coated proppant (RCP). The results demonstrate the potential of using thermochemical compositions to address the fundamental problem of residual damage in low-temperature reservoirs caused by undegraded polymer residues.
Key words:
Guar-borate fluids, thermochemical compositions, thermochemical reaction, heat and pressure generation, rheology, gel degradation, proppant pack, formation damage (ASPO), fracture clean-up, formation clean-up, conductivity, resin-coated proppant (RCP) curing
