Abstract: A borehole completion method treats a formation surrounding a borehole with a chemical treatment that alters how formation particulates interact. A standalone screen deploys downhole in the borehole (either before or after the treatment) on a downhole string. When fluid is produced, formation particulates treated with the chemical treatment agglomerate in the annulus surrounding the screen in permeable structures. This can be especially when the standalone screen is useful in a cased hole having perforations. The chemical treatment includes an inner salt adapted to neutralize the zeta potential (i.e., electrokinetic potential) of the formation particulates so they aggregate into one or more permeable structures in the annulus.

Abstract: A gravel pack assembly gravel packs a horizontal borehole. Operators wash down the borehole using a tool in a first position by flowing fluid from the tool through the apparatus' toe. Operators then gravel pack by moving the tool to a first flow port between a screen and the toe. Slurry flows into the borehole from the first flow port, and returns from the borehole flow through the screen. The gravel in the slurry can pack the borehole in an alpha-beta wave from toe to heel. When the tool has a sleeve, operators can break any bridges by flowing fluid from the passage of the assembly into the tool. In another condition, operators can move the tool to a second flow port. Slurry can flow into to the borehole through a shunt extending from the second flow port. Meanwhile, returns can flow from the borehole through a bypass in the assembly.

Abstract: A device and method allows a bore valve in the washpipe and in certain instances a port valve or sliding sleeve to open or close upon command from the surface so that gravel slurry may be placed in a wellbore.

Abstract: A multi-zone screened frac system combines screens with integrated check valves, frac valves, and optional shunt tubes for slurry dehydration. The system can also include fiber optic technology. In particular, the system uses sliding sleeves and flow devices for each section. The sliding sleeves open with dropped balls or a service tool, and the flow devices have screens and act as check valves. Dehydration tubes can also be used. The system does not require a crossover tool, and in some implementations, the system does not even require a complete service tool.

Abstract: An apparatus and method allow gravel pack slurry to be placed in a borehole annulus from the toe towards the heel to reduce the pressure acting upon the heel of the borehole during the gravel placement operation. By reducing the pressure on the heel, the gravel pack slurry may be placed in longer sections of the borehole in a single operation. Additionally, excess slurry in the inner string can be disposed in the borehole annulus around the shoe track of the apparatus, and fluid returns can flow up the apparatus through a bypass.

Abstract: A gravel packing assembly gravel packs a horizontal borehole. Operators wash down the borehole using an inner string in a first position by flowing fluid from the inner string through the apparatus' toe. Operators then gravel pack by moving the inner string to one or more flow ports between a screen and the toe. Slurry flows into the borehole from the flow ports, and returns from the borehole flow through the screen. The gravel in the slurry can pack the borehole in an alpha-beta wave from toe to heel. In another condition, operators can move the inner string to a second flow port so slurry can flow into the borehole through a shunt extending from the second flow port. When gravel packing is done, operators move the inner string to a port collar in a liner of the assembly to cement the liner in the borehole.

Abstract: A downhole assembly, such as a toe-to-heel gravel pack assembly, has a body with a body passage, outlet ports for slurry, and screens for fluid returns. An inner string deploys in the body to perform the toe-to-heel gravel packing. A telescoping adjustment device allows the inner string to space out properly when deployed to the toe of the assembly. Sealing surfaces or seats of a locating device in the body separate a sealable space and seal against seals on the inner string movably disposed therein. Fluid pumped in the string produces a pressure buildup when the string's port communicates with the sealable space. The pressure buildup indicates that the tool is positioned at a first location in the assembly, and other positions for placement of the tool can then be calculated therefrom.

Abstract: A gravel pack operation disposes slurry from an inner string into the annulus around a shoe track. A valve on the shoe track can open and close flow through a port, and seats around the port allow an outlet of the tool to seal with the port. When the valve is open and the outlet sealed with the port, the slurry in the string is pumped into the borehole around the shoe track by flowing the slurry from the outlet into the borehole through the flow port. As this occurs, gravel collects around the shoe track, and fluid returns in the borehole flow back into the shoe track through a screen disposed toward the track's toe. Once inside the shoe track, the fluid returns communicate through a bypass on the shoe track around the sealed outlet and port. At this point, the fluid returns can pass uphole in the gravel pack assembly.

Abstract: Methods and apparatus for installing deepwater completions and performing well intervention from a vessel that can perform other duties while not running completions or performing interventions. The system for installing deepwater completions and performing well intervention may comprise a surface pipe handling and deployment package including a horizontally operated rig that may also be operated in a slanted mode. Deepwater completions may be deployed from the vessel via a buoyant horizontal riser (BHR), which may be supported by a submerged buoyant tensioning system (BTS). In this manner, the cost of performing completion or intervention operations may be significantly reduced compared to such operations run from a drilling rig.

Abstract: A system and method for cavitating a producible formation is disclosed to improve hydrocarbon production and to increase a production rate without an concurrent co-production of formation particulate. The method and system include conglomerating the producible formation using a conglomerating composition. Once the producible formation is conglomerated, the conglomerated, producible formation is produced above its critical draw down pressure to form a cavity surrounding the wellborn in the conglomerated, producible formation and placing the cavitated, conglomerated, producible formation on production below a higher maximum sand free rate (MSFR).

Abstract: Methods and systems are disclosed for well completion and/or production, where an aggregating, agglomerating or conglomerating composition is injected into a producible formation, zone or interval thereof to alter an aggregation or zeta potential of formation surfaces and particulate to increase a maximum sand free production rate.

Abstract: A well completion system and associated methods of completing wells provides enhanced convenience in well completions involving well treatment operations. In a described embodiment, a single trip perforating and fracturing/gravel packing method permits a well completion assembly including a well screen and a perforating gun to be installed in a well, the well to be perforated and treated, and the perforating gun to be retrieved from the well in a single trip. Retrieval of the perforating gun permits multiple zone completions in the well without the perforating guns remaining in the well thereafter.
