Resumen de Gilsonite lowers well cementing costs
Iran Gilsonite, a company which supplies gilsonite to China, India, Turkey, Europe and the US, among other markets, told IM that its product is mainly used in road construction, however, it states that it can also be employed to prevent shale washouts. Highly permeable sands can be sealed and drill torque and drag can be reduced, the company said.
"While they are effective, hollow beads represent a significant expense," American Gilsonite said. "Field trials have shown that adding gilsonite to cement slurry while reducing the concentration of beads produces considerable cost savings." "Supply constraints have made people more creative and they've started questioning whether they really need 4.2 [specific gravity (SG)] barite densities all the time, with companies considering 4.1 and lower grades," Jim Vernon, director of fluids supply chain and manufacturing at Baker Hughes Inc., told delegates at IM 's Oilfield Minerals Conference in Houston, US, in late June.
