A bottom hole assembly can include an abrasive perforator with at least one nozzle configured to direct an abrasive jet outward from the abrasive perforator, and a plug dispenser tool configured to discharge at least one plug via a plug discharge port into an annulus surrounding the plug dispenser tool. A method of completing a well can include deploying a bottom hole assembly into a wellbore, perforating at least one zone with an abrasive perforator of the bottom hole assembly, and then discharging at least one plug from a plug discharge port of a plug dispenser tool of the bottom hole assembly. The discharging step can include the plug displacing from an internal flow passage of the bottom hole assembly to an annulus formed between the bottom hole assembly and the wellbore.

Well completion systems and methods

A well treatment method can include pumping a treatment fluid through a tubular in a well, deploying plugging devices into the tubular, and blocking flow of the treatment fluid through perforations formed through the tubular. At least one characteristic of the treatment fluid or the plugging devices is varied, thereby in the blocking flow step selectively blocking the flow of the treatment fluid through the perforations in a predetermined sequence. Another well treatment method can include varying at least one characteristic of perforations along an interval, thereby selectively blocking flow of a treatment fluid through the perforations in a predetermined sequence. Another well treatment method can include varying a center flow to side flow (CS) ratio along an interval, thereby selectively blocking flow of a treatment fluid through perforations in a predetermined sequence.

Method of treating an interval via selected perforations/clusters in a subterranean well

A method of dispensing a plug can include deploying the plug into a tubular string including a plug dispenser tool, and applying a pressure differential across the plug, thereby discharging the plug into an annulus surrounding the plug dispenser tool. A plug dispenser tool can include an outer housing having a plug discharge port that provides fluid communication between an exterior of the outer housing and a flow passage extending longitudinally through the plug dispenser tool, and a piston slidably disposed in the outer housing between a closed position in which the piston blocks fluid flow through the plug discharge port, and an open position in which fluid flow through the plug discharge port is permitted. A system can include a plug dispenser tool configured to discharge the plug into an annulus surrounding the plug dispenser tool in response to a predetermined pressure differential applied across the plug.

Downhole plug deployment in a subterranean well

A method can include deploying a diverter plug into a well, the diverter plug comprising a group of particles that are prevented from dispersing, flowing fluid, thereby conveying the diverter plug into engagement with a fluid passageway, the particles conforming to a shape of the fluid passageway as the diverter plug blocks fluid flow through the fluid passageway, and the particles being prevented from dispersing while the diverter plug blocks the fluid flow through the fluid passageway. The diverter plug can include a group of particles disposed within an outer enclosure. The particles in the enclosure can conform to a shape of the fluid passageway as the diverter plug blocks fluid flow through the fluid passageway. In another method, the enclosure can sealingly engage the fluid passageway while the particles remain disposed within the enclosure.

Well operations with grouped particle diverter plug

A jarring tool can include a longitudinally displaceable piston, a first fluid chamber having a volume that decreases in response to displacement of the piston, a flow controller that controls flow of fluid between the first fluid chamber and a second fluid chamber, and a plug seat secured to the piston. A method of applying a jarring force can include applying a pressure differential across a plug in a jarring tool, the plug restricting flow from a first flow passage section to a second flow passage section, then increasing a flow rate of fluid from the first flow passage section. Another jarring tool can include an outer housing with a longitudinal flow passage and seal surfaces at opposite ends of the outer housing, and a flow obstruction, fluid flow through the flow passage being increased in response to application of a pressure differential across the obstruction.

Jarring tool and method of use

A method can include conveying a dispensing tool through a wellbore, the dispensing tool including an enclosure containing plugging devices, and then opening the enclosure by cutting a material of the enclosure, thereby releasing the plugging devices from the enclosure into the wellbore at a downhole location. A dispensing tool can include a container having an enclosure therein, the enclosure including a flexible material that contains the plugging devices, and an end of the enclosure being secured to a member displaceable by an actuator. The enclosure material is cut in response to displacement of the member by the actuator. A plugging device can include at least one body configured to engage an opening in the well and block fluid flow through the opening, and multiple fibers including staple fibers or filaments formed into yarn.

Methods of completing a well and apparatus therefor

A method of constructing a plugging device can include incorporating multiple filaments into the plugging device, and coating each individual filament with a swellable material. A plugging device for use in a subterranean well can include a body comprising multiple filaments, and a swellable material on each of the individual filaments. A system can include a plugging device conveyed by fluid flow into engagement with an opening, whereby the plugging device blocks flow through the opening. The plugging device can include multiple filaments, each of the multiple filaments being coated with a swellable material. The swellable material may seal against a surface of the opening.

Plugging devices having filaments coated with swellable material

A flow conveyed plugging device for use in a well, the device can include a body, and one or more lines extending outwardly from the body, each of the lines having a lateral dimension that is substantially smaller than a size of the body. A method of plugging an opening in a well can include deploying at least one flow conveyed plugging device into the well, the flow conveyed plugging device including a body and, extending outwardly from the body, at least one of the group consisting of: a) one or more fibers and b) one or more lines, the flow conveyed plugging device being conveyed by flow in the well into sealing engagement with the opening. Another flow conveyed plugging device can include a body, and fibers extending outwardly from the body. The flow conveyed plugging device degrades and thereby permits flow through an opening in the well.

Flow control in subterranean wells

A system for use with a subterranean well can include a deployment apparatus configured to deploy one or more plugging devices into a fluid flow. The plugging devices are conveyed into the well by the fluid flow. The deployment apparatus can include multiple queues, different numbers of the plugging devices being contained in respective different ones of the queues. A method of deploying plugging devices can include connecting multiple queues of the plugging devices to a conduit, and deploying the plugging devices from a selected combination of the queues into the conduit. In another system, each of the plugging devices may include a body, and lines or fibers extending outwardly from the body.

Plugging device deployment

A method of treating a subterranean well can include positioning a flow restrictor in a wellbore that penetrates an interval of an earth formation, displacing the flow restrictor along the wellbore away from a surface of the well, preventing longitudinal displacement of the flow restrictor in the wellbore, introducing flow into a first section of the interval from a section of the wellbore between the flow restrictor and the surface, blocking the flow from the wellbore section into the first interval section, permitting longitudinal displacement of the flow restrictor in the wellbore, and displacing the flow restrictor along the wellbore away from the surface of the well, thereby permitting unrestricted flow from the wellbore section into a second section of the interval. The second interval section is farther along the wellbore from the surface than the first interval section.

Fluid flow control during well treatment

Activating a reaction of a sealant, such as cement, with a fiber optic cable, the reaction causing hardening of the sealant. The sealant may be used in wellbore cementing operations to cement a casing in a wellbore. The fiber optic cable may be deployed by attaching it to the outside of a casing during insertion into the wellbore. The activation of the sealant can be via thermal or optical initiation in order to causing a hydration reaction or polymerization.

Systems and methods for sealing casing to a wellbore via light activation

A method can include positioning a flow restrictor in a wellbore that penetrates a formation interval, then displacing the flow restrictor along the wellbore away from the surface, thereby permitting flow into an interval section from a wellbore section between the flow restrictor and the surface, blocking the flow from the wellbore section into the interval section, and displacing the flow restrictor away from the surface, thereby permitting flow from the wellbore section into another interval section farther along the wellbore from the surface. A system can include a flow restrictor that restricts flow through an annulus surrounding the flow restrictor, and plugging devices disposed in a wellbore section positioned between the flow restrictor and a surface of the well. Flow from the wellbore section into a formation interval section is permitted prior to being blocked by the plugging devices.

A method of deploying plugging devices in a well can include a spacing between the plugging devices by controlling a ratio flow rates through intersecting pipes. A deployment apparatus can include an actuator and a release structure that releases the plugging devices into a conduit connected to a tubular string in the well. Another method of deploying plugging devices in a well can include operating an actuator, thereby displacing a release structure, and the release structure releasing the plugging devices into the well in response to operating the actuator. Another deployment apparatus can include intersecting pipes and a valve that selectively permits and prevents displacement of the plugging devices through one of the pipes.
