... are removed. To maximize the recovery with secured operational and environmental safeties threatened by the natures of SMH bearing formation, the understanding of the formation strength is essential. The formation strength is governed by soil and rock mechanics which gradually shift with depth at water...

... ABSTRACT In-situ rock strength with depth under the ground/seafloor is a critical parameter for various studies in geosciences. The measurements on rock/core samples, however, hardly have been done with success due to lack of drilled cores and sufficient knowledge about the in-situ conditions...

... shales. Their laminated nature creates variations in rock strength between the different layers making them very susceptible to rock failure. Unfortunately, these formations are very common and can occur at any stage of the well construction. Traditionally, a one dimensional (1D) geomechanical pre-drill...

... the gradients of shear failure, depth of damage and breakdown. All the workflows used to obtain wellbore stability computation in real time include the determination of lithological facies, the elastic properties of each formation and rock strength parameters. The tectonic strain's correlations from the post...
