Fracturing/pressure pumping
Technology developers expect the tight-oil industry to give lightweight proppants another look after the Permian Basin’s biggest operator becomes an adopter.
This paper describes development of a high-temperature water-based reservoir drill-in fluid using a novel synthetic polymer and customized with optimal chemical concentrations and sized calcium carbonate.
In this case study, a geomechanics-based approach was used to create bridging and sealing at the fracture aperture using a biparticle self-degradable lost-circulation-fluid system.
