Hydraulic fracturing is a well stimulation technique in which rock is fractured by a pressurized liquid. The process involves the high-pressure injection of 'fracking fluid' (primarily water, containing sand or other proppants suspended with the aid of thickening agents) into a wellbore to create cracks in the deep-rock formations through which natural gas, petroleum, and brine will flow more freely. When the hydraulic pressure is removed from the well, small grains of hydraulic fracturing proppants (either sand or aluminium oxide) hold the fractures open.
SEPPE resin-coating technology improves proppant strength and productivity in the downhole environment. It also reduces flowback of proppant from the fracture into the wellbore, which can damage equipment. Resin coating effectively reduces costly cleanout issues in the wellbore by reducing effective stress on the proppant, providing encapsulation to maintain particle integrity and preventing fines from being released.
As SEPPE resin coated proppants used in hydraulic fracturing operations in the oil and gas industry overcome the challenges of traditional phenolic coatings, which can leach environmentally hazardous chemicals. Our wide range of high quality, high performance proppant is manufactured to have a low internal pellet porosity, so that it is strong and durable enough to withstand pressure cycling. So that enables our clients to build fractures that maintain the optimal balance of contact and conductivity for the life of the well.
