Over the years, proppant technology has evolved from sands to engineered, high-strength proppants, cured and partially cured resin-coated proppants to prevent fines, lightweight and deformable proppants, and coated walnut shells for improved transportation and reduced embedment.
The latest in the line-up could be expandable proppants, which are nearing commercialisation from a technology developer in the US.
“We’re working to understand the in-situ application of force in the fracture network to control and manage development of that network,” says Andy Sherman, president and chief executive of Euclid, Ohio-based Terves.
