Challenge: Develop a more accurate and
reliable method to compute the mud-weight window and reduce risk by improving
wellbore stability
Solution: Account for variation in the rock
properties instead of assuming they are homogeneously isotropic by using 3D
data from Sonic Scanner acoustic scanning platform to determine the minimum
horizontal stress
Results: Improved wellbore stability while
reducing risk, nonproductive time, and costs by basing the mud-weight window on
the minimum horizontal stress calculated to account for shale anisotropy
