... complementary models were used in a geomechanics analysis to compensate for the sensor offset difference in the bottomhole assembly (BHA) using the real-time quadrupole shear. The first model is based on geopressure gradients of vertical stress, pore pressure and fracture gradient. The second one incorporates...

... Abstract The accurate prediction of the pore pressure and the in-situ stress field is becoming significantly important for deepwater drilling operations recently in the industry. From the past drilling operation experiences in the Sea of Japan, the overpressure and the borehole instability...

... Abstract Drilling activity in the deepwater fold-thrust belt of Southeast Asia has expanded greatly and has quickly become recognized as one of the five proven deepwater oil regions in the world. Unfortunately, drilling hazards linked to pore pressure (PP)and wellbore stability problems...

... pressure (5–25 MPa), namely various Terzaghi's effective stresses (2–35 MPa). Skempton's coefficient B and undrained bulk modulus were determined by B-test, in which volumetric strain and pore pressure changes with confining pressure. Drained bulk modulus and poroelastic parameter H (inverse number...
