    摘要: A process of designing a screenless completion for an oil or gas well includes selecting an oil or gas well having known characteristics and inputting data about them into a computer; determining, through operation of the computer, whether a screenless completion should be performed on the selected well and, if so, identifying materials to be used in the screenless completion and in response indicating to a user a screenless completion design using the identified materials. Different types of screenless completion designs are made available. These steps can be performed for multiple wells, preferably with similar results for similar wells.

    摘要: Methods are included that are useful in treating subterranean formations and, more particularly, to minimizing particulate migration over long intervals in subterranean well bores that may be horizontal, vertical, deviated, or otherwise nonlinear. In one embodiment, a method is presented comprising: providing a well bore comprising an open hole section of about 30 feet or more that comprises an open hole section with a filter cake neighboring at least a portion of a reservoir; allowing the integrity of at least a portion of the filter cake to become compromised; and treating at least a portion of the open hole section with a consolidating agent system in a single stage operation so as to at least partially reduce particulate migration in the open hole section.

    摘要: A sand control screen assembly (170) is operably positionable within a wellbore (48). The sand control screen assembly (170) includes a base pipe (172) having at least one opening (176) and an internal flow path (174). A swellable material layer (182) is disposed exteriorly of the base pipe (172). A fluid collection subassembly (184) and a sensor (192) are disposed exteriorly of the swellable material layer (182). The fluid collection subassembly (184) is in fluid communication with the internal flow path (174). A filter medium (188) is disposed in a fluid path between the exterior of the sand control screen assembly (170) and the internal flow path (174). In response to contact with an activating fluid, radial expansion of the swellable material layer (182) causes at least a portion of the fluid collection subassembly (184) and the sensor (192) to be displaced toward a surface of the wellbore (48).
