This paper presents a local constitutive model for modelling the linear and non linear behavior of soft and hard cohesive materials with the discrete element method (DEM). We present the results obtained in the analysis with the DEM of cylindrical sa

Managed pressure drilling (MPD), which has been heavily refined and readily practiced in offshore and deepwater operations, could open many doors to untapped potential on land—a concept often underestimated. Operators look to MPD technologies—for

Summary A dynamic stiff-string torque-and-drag (T&D) model is presented that assumes steady-state motion of the drillstring as its basis for calculations. Results are compared with previously published T&D models that are based on static equilibrium.

Publikováno v: Volume 7A: Fluids Engineering Systems and Technologies.

The current paper presents the numerical simulation of the wave propagation phenomena in the Newtonian and non-Newtonian drilling mud flow associated with oil/gas drilling activities. The formation of wave due to back pressure changes by means of a c
