Abstract

Summary

The results of this work demonstrate that the wellbore trajectory parameters have significant influence on the fracture pressure, as well as fracture localization on the borehole wall. Authors implemented tensorial approach in order to calculate principal stresses near the borehole, taking into account wellbore inclination and azimuth. Data from several wells were processed and the results show that the relative change of the minimum principal stress magnitude can be up to 40% in case of inclination change from 0 to 90 degrees.

According to the pore pressure values, relative change of fracture pressure in such case is up to 90%. The described approach allows determination of fracture orientation on the borehole wall, i.e. angle between fracture plane and borehole axis. Like the fracture pressure, the fracture orientation depends on the wellbore trajectory parameters. This effect is important for the fracture geometry modeling, which is performed during the fracture design procedures.
