    摘要： As a representative embodiment of the methods of the invention disclosed herein, a through-tubing bridge plug having an expansible packing element and a tubular screen dependently coupled thereto is passed through a production string into a well bore therebelow and positioned adjacent to a perforated formation interval containing loose formation materials. The initial production of connate fluids from the well is controlled at a reduced rate for slowly drawing loose formation materials into the perforated well bore interval to at least substantially fill the annular space around the tubular screen with such formation materials. Then, once it is believed that the annular space around the tubular screen is filled with such loose formation materials, production of the well is commenced in the usual manner with the packed formation materials around the screen serving as a filter media to inhibit the entrance of further formation materials into the well bore.

    摘要： The invention disclosed herein is directed to new and improved control apparatus for selectively operating pressure-actuated well tools. In particular, different embodiments are disclosed of control apparatus for well completion tools and especially adapted for repetitively operating at extreme pressure differentials typically experienced in well bores to selectively extend and retract wall-engaging members on the tools.

    摘要： In the representative embodiments of the new and improved methods and apparatus for testing earth formations disclosed herein, fluid-admitting means are placed into sealing engagement with a potentially-productive earth formation. A first test chamber coupled to the fluid-admitting means is then slowly expanded at a known rate of expansion to induct a minor volume of producible connate fluids, if any, from the formation into the chamber. Thereafter, a second test chamber also coupled to the fluid-admitting means is quickly expanded at a known higher expansion rate to induct a second minor volume of connate fluids into the second chamber. By monitoring the resulting fluid pressures as these first and second samples are successively inducted, reliable surface indications are quickly provided of at least the approximate flow rates at which large-volume samples can be subsequently collected from the earth formation.
