Estimating rock mechanical properties of the Zubair shale formation using a sonic wireline log and core analysis

The predicted continuous rock mechanical profile gives a good indication of the strength and stability of the shale around the wellbore. Consequently, it can be used to solve shale instability problems, optimize drilling processes (i.e., the selection of bit type and drilling parameters), seal integrity evaluation, and otherwise improve fracturing operations across the Zubair shale formation.
