Abstract

Three typical borehole wall shifts during lost circulations are studied and parameter studies are conducted for evaluating the magnitude of the shifts. (A) Slant-crack induced around vertical wells during lost circulations. Parameters varied are the frac size/wellbore size, frac angle, borehole pressure and σ_H1.σ_H2σ_v ratio. (B) Borehole wall shifts induced during the drilling of normal, thrust, and strike-slip fault areas. (C) Borehole wall shifts induced for an inclined well due to a fracture induced in perpendicular to the minimum in-situ stress.
