(42) A NEW TECHNOLOGY THAT DELIVERS LONG-TERM CHEMICAL TREATMENT DURING WELL STIMULATION: ORGANIC DEPOSIT AND INORGANIC SCALE CONTROL
A new technique of delivering long-lasting treatment for damaging well conditions, such as scales, corrosion, or organic deposits, has been achieved using a novel technology. This new technology involves a viscoelastic, biopolymer-hydrogel as the matrix to incorporate and transport chemicals into the formation. When placed in the fracture length, the porous matrix controls the release of the treatment agent over long period of time.
The system is environmentally safe and cost-effective, and designed to be pumped with stimulation fluids during proppant transport. This technology has proven to provide a more efficient delivery, placement, and long-term chemical treatment compared to other existing technologies, where maximum loading of the product is restricted to below 2% of the total proppant.
