STABView - a software program for wellbore stability, sand production, lost circulation and discontinuity slip risk analysis. STABView was developed for technical drilling, completion, production and exploration personnel to conduct rapid parametric analyses for a wide range of near-wellbore integrity problems. Efficient, rapidly converging, analytical and semi-analytical algorithms are used to solve the fundamental equations that describe the stresses, pore pressures, and temperature distributions for near-wellbore problems. Additional information regarding these models is included in Section 4 of this manual.
