Loss of circulation while drilling is a challenging problem that may interrupt operations, contaminate the subsurface formations and add more cost. It is a widely encountered problem in various industries, including oil&gas, geothermal, CO2 geological sequestration, environmental remediation, nuclear waste industries, etc. Analytical modeling of fluid flow in fractures is a tool that can be quickly deployed to assess drilling mud leakage into fractures. We developed a new semi-analytical solution to model the flow of non-Newtonian drilling fluid in fractured formations. The model is applicable for various fluid types exhibiting yield-power-law (Herschel-Bulkley).
