Provided is a filter plug, a well system, and a method for fracturing a well system. The filter plug, in one aspect, includes a filtration skeleton. The filter plug according to this aspect further includes a degradable material in contact with the filtration skeleton, the filtration skeleton and degradable material configured to lodge within a port in a wellbore, and thus substantially plug the port when the degradable material remains intact with the filtration skeleton and allow the filtration skeleton to filter particulate matter as fluid passes there through when the degradable material no longer remains intact with the filtration skeleton.

An actuation member for use in fracking operations, which immediately prior to fracking locates a sand screen at a desired location along a tubing liner and eliminates having to trip out the frac string prior to commencing production. The actuation member comprises a cylindrical hollow collet sleeve, with one or more radially-outwardly biased protuberances forming a unique profile which further matingly engages a corresponding mating profile on one of a plurality of sliding sleeve members in the tubular liner. A longitudinally-extending sand screen is provided, longitudinally slidable on the actuation member. A spring member, adapted to be forcibly compressed by the sand screen member when pressurized fluid is applied, and decompressed upon removal of pressurized fluid, is further provided on the actuation member.

The present invention is related to a downhole device for hydrocarbon producing wells without conventional tubing (tubingless completion), which improves the hydrocarbon production (gas, oil and condensate), selectively controls produced solids (reservoir sand and hydraulic fracture proppant) and eliminates liquid loading. The device of the present invention is designed according to selected well and reservoir characteristics by an integral methodology which includes the stages: data collection and analysis of the well operating conditions, selection of candidate well, sampling and analysis of produced solids, simulation of production conditions, design and manufacture and installation.

The device of the present invention: Is installed, through an operation with slick line unit or any other operational method, to any well depth, according to well mechanical characteristics and needs; Has a filtering element at the lower end which selectively retains produced solids from 50 microns, avoiding their transport from bottomhole to surface with produced fluids in the well, causing pressure drops through filtering element and porous media, and protecting of abrasion all components of petroleum production system; Improves well production conditions due to the system internal geometry, generates a suction and dispersion effect of accumulated liquid in bottomhole, reducing up to 70% of pressure requirement to transport free of heavy particles liquids, from bottomhole to surface and increasing hydrocarbon production up to 300%; Takes advantage of expansion energy of reservoir gas to change the intermittent flow pattern into dispersed flow pattern, increases gas velocity at least to 6 m/s, optimizing the flow pattern from bottomhole to surface, and extending the productive life; and Optimizes the remaining reservoir energy and pressure, reducing produced water up to 60%, avoiding the premature use of other technologies to promote hydrocarbon production.

Treatment method for a rock formation against sand infiltration during production of fluid from this rock formation via a well drilled through said rock formation, comprising at least one step of injecting a geopolymer cement grout into said rock formation, in particular around the edges of said well and/or through said well.

A method for making a permeable filter in a wellbore includes introducing a spacer material comprising a plurality of solid particles to a rock formation penetrated by the wellbore. A binder material is introduced to the rock formation. The binder material is susceptible to change of state from liquid to solid. The state of the binder material is changed from liquid to solid, and a size of at least some of the plurality of particles of the spacer material is reduced.

An electric submersible pump includes a pump, an electric motor that is coupled to the pump by a rotatable shaft, a seal section that is positioned between the pump and the electric motor. The seal section contains a sequestration device and a motor oil for the electric motor. The sequestration device includes a superabsorbent polymer to contact the motor oil and to react with a wellbore fluid from a wellbore to prevent premature failure of the electric submersible pump from the wellbore fluid contamination of the motor oil.

A fluid control device includes a filtration component, which has a porous filtration medium. The filtration medium contains a shape memory thermoset material foamed with a polymeric microsphere and a gas-producing chemical foaming agent. The porous filtration medium is configured to be compacted from an initial shape to a compacted shape, deployed in the borehole, and subsequently expanded to conform to a surface of the borehole.
