The electrical behavior of three different Epoxy-Based composite materials was studied by varying different test parameters. The electrode clamping force, the applied voltage, and the effects of the presence of water have been investigated in this wo

Sidetracking a cased wellbore presents numerous challenges because the operators have to plan ahead to select the sidetracking depth and then ensure that all the objectives are met from a well authority for expenditure and geological target perspecti

A polycrystalline diamond compact (PDC) bit was used to drill a northern Kuwait well. The typical casing design for this field calls for the 16-in. section to be the longest section in the well, which extended from 1,230 ft to 6,000 ft for a total of

Drilling the 12¼-in hole in southern Kuwait usually starts in a shale formation and continues through interbedded sandstone, limestone, and shale. The unconfined compressive strengths throughout the section vary from 6,000 psi to 10,000 psi. The bit

We investigate the role of defects in a model order-disorder transition, the lamellar-microemulsion transition. We focus on the effect of an applied external stress on the transition mechanism. We first analyse the thermodynamical consistency of the

When a vesicle, delimited by a flexible surfactant membrane, is confined to a slit or a cylindrical capillary, its accessible free volume is reduced. It is shown that the corresponding increase in free energy, taken as the sum of curvature elastic en
