A perforated filtration insert includes a head unit and a body portion having perforated side walls. The body portion is closed at one end by a cap such that fluid entering the body exits through the perforations in the side walls of the insert.

A screen assembly includes a tubular having a first end, a second end, and an intermediate portion including an outer surface provided with a plurality of openings extending therebetween. At least one screen arranged at the plurality of openings. At least two deformable members are mounted to the tubular between the first end and the second end. The at least two deformable members are selectively radially outwardly expandable relative to the at least one screen forming a plurality of screen compartments on the tubular, the plurality of screen compartments being substantially fluidically isolated from one another externally of the tubular.

A method of passing downhole fluids through a screen assembly mounted to a tubular run into a well bore. The screen assembly has a plurality of screen sections arranged at a resource production zone between a first swellable member and a second swellable member. The method includes passing a fluid through an annular screen of the plurality of screen sections into the tubular. At least a portion of the fluid includes particulate matter. Particulate matter is accumulated at the annular screen. Particulate matter is detected in the fluid. The fluid passes into one or more of a plurality of inner screen compartments provided on an inner tubular member radially inwardly spaced from the tubular, and the fluid is filtered through an erosion resistant annular screen of one or more of the plurality of inner screen compartments.

A recirculating gravel pack system includes a tubular member having an outer surface, an inner surface defining a flow path, a first opening extending from the inner surface through the outer surface and a second opening, spaced from the first opening extending from the inner surface through the outer surface. A screen is positioned about the tubular member spaced from the outer surface defining a passage that is selectively fluidically connected to the second opening. A return tube extends between the screen and the outer surface running axially along the tubular member. The return tube includes a first end defining an inlet arranged in the passage and a second end defining an outlet positioned in a low-pressure zone outside the passage downhole from the first opening.

An adaptive fluid switch for regulating the production rate of a fluid. The adaptive fluid switch includes a fluid control valve having a fluid selector, a swirl chamber and a self-impinging valve element. When the fluid produced through the adaptive fluid switch has a viscosity greater than a first predetermined level, the fluid selector determines the fluid to be a selected fluid such that the fluid swirls in one direction in the swirl chamber and follows a low resistance flow path in the valve element. When the fluid has a viscosity less than a second predetermined level, the fluid selector determines the fluid to be a non-selected fluid such that the fluid swirls in the opposite direction in the swirl chamber and follows a high resistance flow path in the valve element, thereby regulating the production rate of the fluid responsive to changes in the viscosity of the fluid.

A ternary water control and gas recovery method suitable for an unconsolidated siltstone gas reservoir is provided. It includes the following steps: first, running a silt control screen pipe manufactured by an interface hydrophobic modification into a wellbore to realize wellbore water control and silt control; second, filling a surface hydrophobic modified gravel in an annular space between the silt control screen pipe and the wellbore to form a hydrophobic gravel packing layer for water control and silt control; third, injecting a wetting agent aqueous solution into a stratum, and performing a hydrophobic modification on a gas reservoir seepage channel surface to realize in-situ waterblocking and silt migration of the unconsolidated siltstone gas reservoir, and then closing a well for a preset time before exploitation.

In some implementations, a method involves determining a level of accumulation of a hydrocarbon-water emulsion in an annulus of a wellbore. The method further involves based on the level of accumulation, determining an operating setting of a hydrocarbon-water separator and operating the hydrocarbon-water separator at the operating setting, where the hydrocarbon-water separator separates the hydrocarbon-water emulsion into water and a hydrocarbon fluid. Further, the method involves activating, in response to a first sensor detecting a first water level in the annulus, a pump that pumps the water from the annulus into a water zone below the wellbore. Yet further, the method involves deactivating the pump in response to a second sensor detecting a second water level in the annulus, where the second sensor is located below the first sensor.

A system for a well completions operation includes a packed filtration screen assembly removably attached around a perforated portion of a liner, where the packed filtration screen assembly has an inner slotted basket, an outer slotted basket positioned concentrically around the inner slotted basket, and gravel held in an annular space between the inner slotted basket and the outer slotted basket and axial end caps located at opposite axial ends of the annular space.

A recirculating gravel pack system includes a tubular member having an outer surface, an inner surface defining a flow path, a first opening extending from the inner surface through the outer surface and a second opening, spaced from the first opening extending from the inner surface through the outer surface. A screen is positioned about the tubular member spaced from the outer surface defining a passage that is selectively fluidically connected to the second opening. A return tube extends between the screen and the outer surface running axially along the tubular member. The return tube includes a first end defining an inlet arranged in the passage and a second end defining an outlet positioned in a low-pressure zone outside the passage downhole from the first opening.

A gravel packing assembly has first and second joints each including a sand control screen assembly having a filter medium positioned exteriorly of a base pipe and a slurry delivery subassembly rotatably mounted exteriorly on the sand control screen assembly. The slurry delivery subassembly includes at least one transport tube extending longitudinally along at least a portion of the sand control screen assembly. At least one jumper tube is coupled to and extends between the at least one transport tube of the first joint and the at least one transport tube of the second joint. The at least one transport tube of the first joint is axially aligned with the at least one transport tube of the second joint by rotating the slurry delivery subassembly of the first joint relative to the sand control screen of the first joint after the two joints are coupled together.
