CHEMICALS AND UNIQUE TECHNOLOGIES FOR RESERVOIR FRACTURING AND STIMULATION

Suspending liquid guanidine gum fracturing fluids: Includes suspending liquid guanidine gum, high-temperature organic borate crosslinker, clay stabilizer, cleanout additive, emulsion preventer, demulsifier, and imbibition extractor. This technology eliminates the inconvenience of on-site mixing of guanidine gum fracturing fluids and allows for mixing of fracturing fluids on the fly, greatly improving the mixing speed and reducing on-site labor intensity.

Clean polymer fracturing fluid system: Includes polyacrylamide powder, polyacrylamide suspension, organic titanium and zirconium composite crosslinker, clay stabilizer, cleanout additive, emulsion preventer, demulsifier, and imbibition extractor. Integrated with slick water, low viscosity fluids and cross-linked fluids, this technology applies to the fracturing and stimulation of reservoirs ranging from 80 C to 160 C by adjusting the concentration of polymer and cross-linker.

Temporary plugging agent for fracturing: Temporary plugging agent in particles, braided balls, and balls. This technology utilizes the refabrication of thermoplastic resins to obtain a series of temperature-controlled, water-soluble temporary plugging agents which can block the perforations and fracture fronts. Temporary plugging increases the stimulated volume and stimulation effect.

CHEMICALS AND UNIQUE TECHNOLOGIES FOR ACIDIZING AND STIMULATION

Suspending nano solid retarded acid system: Nano retarded acid suspension system. This nano retarded acid is an environmental-friendly biopolymer material with zero corrosion and zero pollution. It can release a biological acid under certain temperature conditions, achieving deeply-penetrated acidizing and acid fracturing in limestone reservoirs and delivering good results.

Biological acid system: Polyamino acid, phytic acid and malic acid. This acid solution system is mainly made from biological and plant extracts, featuring low reaction speed, low environmental pollution and applicability to the acidizing of limestone containing sandstone and acid fracturing and acidizing of limestnsvrs.

CHEMICALS AND UNIQUE TECHNOLOGIES FOR GAS EOR

Foam agent system: Conventional foam agents, salt-resistant foam agents, high-temperature foam agents, oil-resistant foam agents, silicone defoamers, crude oil defoamers, and various types of foam stabilizers.

Viscosity reducer system: Oil soluble viscosity reducer, water soluble viscosity reducer and foaming viscosity reducer.

Water shutoff and profile control system: Shutoff jelly, shutoff gel and shutoff particles.
