Methods and systems for the testing lost circulation materials

摘要

Apparatus and methods for simulation of bore hole fractures are disclosed. A device for simulating a fracture in a subterranean formation comprises a housing, a gap in the housing, and one or more shims positioned inside the gap. The shims cover at least a portion of a surface of a wall forming the gap. The device further comprises an inlet for directing a sample fluid into the gap. The sample fluid flows through the gap and flows out of the gap through an outlet. Analysis of plug formation in drilling fluid containing lost circulation materials.
