Laboratory and Field Study of a Nanoparticle Lubricant in Aqueous Drilling Fluids in the Bakken formation of North Dakota
“Drilling horizontal wells in the Williston Basin shale plays show high torque and drag and are often limited by low ROP and high lubricant usage with drill bits lasting 15,000-21,000feet. The Bakken formation is a relatively tight formation with low porosity and low permeability rock, from which oil flows with difficulty. “
