A downhole well tool assembly can include a perforator and a selectively openable and closable perforation plug discharge port. A method of perforating and treating multiple formation zones of a well in a single trip of a downhole well tool assembly into the well can include positioning the downhole well tool assembly at a zone, closing a perforation plug discharge port of the downhole well tool assembly, perforating the zone, treating the zone, opening the perforation plug discharge port, deploying perforation plugs into the well via the perforation plug discharge port, plugging perforations in the zone with the perforation plugs, positioning the downhole well tool assembly at a subsequent zone, closing the perforation plug discharge port, perforating the subsequent zone, and treating the subsequent zone.

Multi-zone perforate and treat method

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 casing string is augmented with one or more variable flow resistance devices or 'vibrating tools' to facilitate advancement of the casing and distribution of the cement in the annulus once the casing is properly positioned. Vibrating tools in the form of plugs can be pumped down and landed inside the casing string. The method includes vibrating the casing string while advancing the casing down the wellbore or while the cement is pumped into the annulus, or both. After the cementing operation is completed, the devices may be drilled out or retrieved with fishing tools to reopen the casing string for further operations. One or more wipers may be provided on the plugs, but the section housing the flow path may be free of wipers to allow the size and flow capacity of the flow path to be optimized.

Methods and devices for casing and cementing wellbores

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 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 method of deploying a plug in a subterranean well can include positioning a tool string in the well, the tool string including a plug release tool and a well tool, then releasing the plug from the plug release tool, and then operating the well tool in response to the releasing the plug. A plug release tool for use in a subterranean well can include an outer housing, and an insert secured in the outer housing, the insert including multiple longitudinally extending flow passages formed through the insert.

Downhole plug deployment

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 fluid pulse generator can include a fluid motor including a rotor that rotates in response to fluid flow, a variable flow restrictor positioned upstream of the fluid motor and including a restrictor member rotatable relative to a ported member and longitudinally displaceable relative to the rotor. Another fluid pulse generator can include a flex joint or a constant velocity joint connected between the restrictor member and the rotor. In another fluid pulse generator, the variable flow restrictor can include a valve and a fluidic restrictor element, the valve being operable in response to rotation of the rotor, the fluidic restrictor element being configured to generate fluid pulses in response to the fluid flow through a flow path, and the valve being configured to control the fluid flow through another flow path connected in parallel with the first flow path.

Fluid pulse generation in subterranean wells

A method can include directing fluid flow longitudinally through a well tool connected in a tubular string downstream of a longitudinally compressed circulating valve assembly, thereby causing the well tool to operate, and longitudinally elongating the circulating valve assembly while the fluid flow is ceased, and then increasing the fluid flow, thereby causing the fluid flow after the elongating to pass outwardly through a housing of the circulating valve assembly to an external annulus. Another method can include directing a fluid flow through a well tool connected in a tubular string downstream of a circulating valve assembly, thereby causing the well tool to operate, and decreasing then increasing a flow rate of the fluid flow, thereby causing the fluid flow to pass outwardly through a housing assembly of the circulating valve assembly to an external annulus. Circulating valve assemblies are also disclosed.

Multi-zone perforate and treat system and method

A rotary actuator assembly can include a fluid motor with a rotor that displaces with hypocyclic precessional motion within a stator in response to fluid flow through the fluid motor, and a gear reducer section including an input gear that is fixed relative to the rotor and displaces with the hypocyclic precessional motion relative to an output gear. Another rotary actuator assembly can include a fluid motor with a rotor having a central longitudinal axis that rotates about a central longitudinal axis of a stator, and a gear reducer section including an input gear that rotates with the rotor and displaces relative to an output gear, and the input gear having the same central longitudinal axis as the rotor. A well system can include at least two fluid motors, and fluid flow through one fluid motor causes rotation of the other fluid motor in the well.
