... an energy loss during the contact. The vector n → indicates the normal direction given by the radial displacement vector. The friction force and torque are related to the normal contact force and characterized by the static ( μ s ) and dynamic ( μ d ) coefficients. We can observe that the contact...

... the open-hole interval, centralization of such a PDL assembly is key to accomplishing wellbore cleanliness during displacement of the drilling mud to completion brine. Unfortunately, due to the need to maximize the area open to flow within the PDL, the liner centralization strategy is limited. Furthermore...

All the algorithms have been parameterized to facilitate easy tuning of thresholds. An alerting...

... and a step-motor with a microcontroller allowing for the control and measurement of the side loadings and lateral displacements. A slurry fluid pump system is designed to feed water-based or oil-based muds at the contact surfaces. The as-received drillpipes and casing materials were analyzed by microscope...

... incompatible with each other and to help push the drilling fluid out of the well so the annulus may be completely filled with cement. If the drilling fluid is not successfully displaced from the annular space, the zonal isolation intended by the primary cement job is usually less than ideal. In addition...
