Wellbore stability is achieved through a balance of 3 major factors: the earth’s stresses, rock strength, and pore pressure. Aquitaine Energy Ltd. applies trusted geomechanics to assess and maintain wellbore safety and stability through:

• Calculation of shear and tensile fractures along the borehole walls, including predicting the pressures at which borehole breakouts and breakdowns may occur.

• mud-weight window simulation with changes in the borehole's deviation and azimuth.

• Calculation of mud weights to maintain mechanical stability within the borehole.
