Zusammenfassung: | This invention relates, in general, to a sand control screen assembly positioned in a production interval of a wellbore and, in particular, to a sand control screen assembly having a seal member that prevents fluid flow from the interior to the exterior of the sand control screen assembly during the treatment of single or multiple formations during a single trip into the well.
A sand control screen assembly () and method for treating multiple formations traversed by a wellbore () in a single trip are disclosed. The sand control screen assembly () includes a base pipe () with multiple openings () that allow fluid flow therethrough. A filter medium () is positioned about the exterior of the base pipe () to filter particulate matter out of the production fluids. One-way valves () are positioned within the openings () of the base pipe () to prevent fluid flow from the interior of the base pipe () to the exterior of the base pipe () during and following a treatment process. The one-way valves (), however, are actuatable to allow fluid flow from the exterior of the base pipe () to the interior of the base pipe () to allow production of fluids from the formation (). |
