SUPER WELL WITH STRESSED SCREEN

The destruction of well bottom zone and the sand production limit the well deliverability. The influx of sand also results in a failure of screens, pipes, and other equipment. There are various devices for sand control such as sand screens, slotted liners, perforated liners, etc. Many of the wells are completed with a gravel pack located in the annular space between the wellbore wall and the screen. The new technologies include the use of expandable screens [1]. They allow one to remove gaps in gravel and to produce a denser packing. Practically all existing effective tools are for passive sand control but nor for preventing of reservoir destruction. The objective of this work was to analyze the new well completion with stressed screen (SS). These screens operate so that create necessary mechanical stresses in the reservoir near the wellbore. The using of the stressed screen is the way to get a super well with maximum production rate limited only by reservoir energy and throughput of pipes. The stressed screen can include gravel packing between the screen and a wellbore wall. Another way to create a stressed screen may be the installation of the screen during reservoir drilling. Similar problems are of the great practical and economic importance because their solution will allo
