TL;DR: In this paper, the authors present an apparatus and methods for forming an annular isolator in a borehole after installation of production tubing, where reaction chemicals are carried in the tubing and injected into the annulus to react with each other and ambient fluids to increase in volume and harden into annular seal.
Patent
Sand control screen assembly and treatment method using the same
TL;DR: In this paper, a sand control screen assembly and method for treating formations traversed by a wellbore in a single trip are disclosed. But they do not specify a method for using the filter medium to filter particulate matter out of production fluids.
Patent
Fluid flow control device and method for use of same
TL;DR: In this paper, a fluid flow control device for use in a wellbore to control the inflow of production fluids comprises a sand control screen (62) having a base pipe (64) with a first set of openings (66) allowing the production fluids to flow therethrough and a sleeve (74) coaxially disposed adjacent to the base pipe.
Patent
Expandable well screen
TL;DR: In this paper, an expandable well screen provides increased collapse, torsional and tensile strength for conveyance and positioning in a wellbore, while also having sufficient strength to prevent collapse when the screen is radially expanded.
Patent
Screened well drainage pipe structure with sealed, variable length labyrinth inlet flow control apparatus
TL;DR: In this paper, a drainage pipe section for a horizontal underground well has a base pipe coaxially circumscribed by a tubular structure having a longitudinally intermediate portion defined by a sand screen assembly.
