... the ability of numerical vibration model to predict recorded vibration in the field. The objective of this paper is to evaluate the capabilities of two different rock-bit interaction models with two different ROP formulations for predicting the actual behavior seen in the field. The first model (Model-I...

The basis of the argument comes from micro-mechanics understanding that reveals the pore-scale process interactions that occur during geomechanics//fluids interactions in constrained situations. The analysis reveals that increasing pore pressure (from external causes) leads to increases in stress...
