Drill Cuttings Re-Injection

机译:钻屑再注入

摘要

A method for re-injecting formation solids into a subsurface formation includes obtaining a volume of solid particles from drilling returns, and then obtaining an aqueous operations fluid comprising at least one surfactant. Mixing a volume of the operations fluid with the volume of solid particles to form a slurry which is injected into a disposal well which includes a NAF filter cake. Then injecting the slurry into one or more fractures formed in the subsurface formation such that the slurry contacts the NAF filter cake en route to the one or more fractures.
