摘要： System and method for adjusting the values of the prognostic variables near the interface between a nonhydrostatic, high resolution model embedded in a hydrostatic, coarser resolution model. The system and method condition the outer domain lateral boundary values to enforce conservation of volume when the variables are interpolated onto the inner domain grid. The conditioning adjusts the baroclinic normal velocities at the open boundaries before interpolation. The system and method also include a relaxation scheme which matches the values of the prognostic variables across a zone near the open boundaries of the submesoscale inner domain to prevent the development of discontinuities, reflections and perimeter currents at the periphery of the inner domain.

摘要： A method of perforating and gravel packing a wellbore casing, having the following steps: (1) making-up to a pipe string: a packer, a screen, and a perforating apparatus; (2) running-in the pipe string until the perforating apparatus is at a depth of intended perforations; (3) setting the perforating apparatus in the wellbore casing at a depth of intended perforations; and (4) disconnecting the screen and perforating apparatus from the pipe string. A system for perforating and gravel packing a wellbore casing, having: a packer which is mechanically communicable with a service string: a screen in mechanical communication with the packer; a perforating apparatus in mechanical communication with the screen, wherein the screen and perforating apparatus are detachable from the packer; and a tool having at least one casing engaging slip segment, wherein the tool is matable with the perforating apparatus, and wherein the tool is settable in the wellbore casing.
