Abrégé

A downhole tool, such as a bridge plug, has a carrier disposed on the tool between the opposing cones. Slips are disposed adjacent to the tool between the carrier and the cones. One arrangement has a proximal end of each slip connected by a linkage configured to articulate the proximal end relative to the carrier, while a distal end of each slip is configured to engage the cone opposed thereto. The linkage can be a linkage hingedly connected between the slip's proximal end and the carrier. Alternatively, the linkage can be a leaf spring flexibly connected between the slip's proximal end and the carrier. Another arrangement has linkages hingedly connected to the carrier and hingedly connected toward opposing ends of each slip. The linkages articulate the slip relative to the carrier while the ends of the slip engage the opposing cones.

Abrégé

A flowback tool (100) is used on a top drive for delivering fluid flow to a tubular (60), such as drillpipe or casing. A mechanical stroke (110) on the tool has a barrel (140) and a mandrel (120), which has a mud saver valve (130). The mandrel connects to a quill (40) of the top drive and has a coupling that can be threaded with the tubular's box connection (124a). The barrel disposed on the mandrel can be moved by a cam engagement as the mandrel is rotated. When prevented from rotating with the mandrel, the barrel can thereby move in a stroke direction along an axis. An annular seal (150) on the barrel is configured to sealably engage with the tubular. A clutch (160) disposed on the barrel can prevent rotation of the barrel when the clutch is engaged with a portion (bail) of the top drive. However, a toque threshold of the clutch allows for slippage during operations.

Abrégé

A cementing operation cements casing in a borehole. A bottom plug pumped down the casing ahead of cement lands at a float valve. Circulation of the cement is established through the bottom plug to a shoe track downhole from the float valve. A top plug pumped down the casing behind the cement lands on the bottom plug. An internal component of the float valve is released by building-up pressure in the casing behind the internal component up to a release threshold. The internal component can latch at the shoe. At least some of the cement in the shoe track is displaced from the casing's shoe to the borehole by pumping the plugs and the internal component to the shoe. With the cement displaced out of the shoe track, the time required to drill out the assembly can be greatly reduced.

Abrégé

An equivalent circulating density (ECD) reduction tool can include a positive displacement fluid motor, and a fluid pump configured to be driven by the fluid motor. The fluid pump can include a fluid inlet and a fluid outlet disposed on respective opposite sides of an external flow restriction. A method of controlling equivalent circulating density (ECD) in a well can include connecting an ECD reduction tool in a tubular string, deploying the tubular string with the ECD reduction tool into the well, thereby forming an annulus between the tubular string and a well surface surrounding the tubular string, and flowing a fluid into the well through the tubular string, the fluid returning from the well via the annulus. The flowing step can include operating a positive displacement fluid motor of the ECD reduction tool, the fluid motor thereby rotating an impeller shaft of a fluid pump.

Abrégé

A multistage cementing assembly (20) is used for cementing casing in a borehole. A subsurface tool (60) on the casing holds a subsurface plug (110) therein using a temporary retainer. The subsurface plug is located in a subsurface location below one or more stage tools (60) or cementing collars on the casing. First stage cement passing down the casing can pass through a passage of the subsurface plug to flow out of a float valve (30). A wiper plug (120) passed through the casing behind the cement is then engaged with the subsurface plug. Pressure buildup can release the two plugs as a unit from the temporary retainer. Before reaching the float valve, a deformable ring on the subsurface plug can engage in a locator ring on the casing to indicate the plug unit's location during operations. Eventually, additional stages can be cemented using the one or more stage tools uphole on the casing.

Abrégé

An anchor catcher tool can support tubing in casing. The tool is a slimline tool that can be set and unset with a partial (quarter) turn of a mandrel using a setting mechanism, such as a J-slot and pin arrangement. Uphole and downhole cages of the tool carry opposing slips. When set, the slips engage opposing cone faces to wedge against the casing and prevent movement of the tool. Excluded gas can flow up the annulus to the surface through aligned longitudinal flow paths on the exterior of the tool's components. To do this, a sleeve floating on the mandrel has the cone faces thereon and is longitudinally engaged with cages, which float on the mandrel and carry the slips. The sleeve keeps longitudinal channels on the cages and longitudinal divisions of the cone faces aligned with one another to produce the flow paths for annular flow.

Abrégé

Methods and systems for logging a wellbore having a casing using ultrasonic logging are described. Traditional ultrasonic logging involves using a piezoelectric transducer that is spaced from the inner surface of the casing by a least a distance referred to as the "far-field" distance. Logging in the "far-field," as traditionally done, avoids destructive interference. The methods and systems described herein allow logging in the "near-field." Logging in the near- field using the described methods and systems overcomes several difficulties associated with acoustic logging, particularly in attenuative, dispersive, and deviated environments.

Abrégé

When cementing tubing in a borehole, a wet shoe track is created, and pressure testing of the tubing is performed. To do this, a wiper plug seats in a seat of an insert disposed in a first position in a flow bore of a tool. The insert is released and moved toward a second position in the flow bore in response to the first pressure applied against the seated wiper plug. A collar disposed on the wiper plug seats on a second seat disposed uphole of the first seat. The tubing is pressure tested by applying pressure down the tubing against the wiper plug with the collar seated in the second seat. Fluid communication is then established through the flow bore downhole of the wiper plug, the first seat, and the second seat by removing the collar from the wiper plug. This can create the wet shoe track.

Abrégé

An assembly is used for chemical injection through a wellhead (10) to a capillary line (102) in a well. A capillary hanger (150) installs in the wellhead to support the capillary line (102). A no-return valve (160) of the capillary hanger prevents fluid communication uphole from the supported capillary line (102). An injection module (104) mounts above a gate valve (50) on the wellhead and includes a movable mandrel (120) disposed therein. Hydraulic pressure applied to a piston chamber (121) in the module extends the mandrel through the open gate valve (50) so that a distal end (134) of the mandrel (120) can open the no-return valve (160). At this point, chemical injection introduced into the module can communicate through a flow bore (122) of the extended mandrel, through the open non-return valve (160), and on through the supported capillary line (102) in the well.

Abrégé

Fail-safe methods for deactivating the pulsed neutron generator (PNG) of a logging tool are described herein, as are logging tools configured to execute the fail-safe methods. The fail- safe methods deactivate the PNG if the logging tool is disposed in air outside of a borehole. Measurements taken using one or more gamma ray detectors of the logging tool are used to calculate a value for a parameter that is indicative of the tool being disposed in an air environment. Examples of such parameters include ratios of capture gamma rays and burst gamma rays. The disclosed methods operate without reference to sensors and/or control from outside the tool. The methods do not inadvertently deactivate the tool when it encounters an air-filled borehole.

Abrégé

A system and method set a liner hanger in a borehole by actuating a hydraulic setting mechanism on the hanger to engage slips in the borehole. A setting tool runs the hanger into position. A reserve volume of the tool holds a clean fluid separate from the borehole. A piston of the tool has a tool volume for the fluid. During run in, pressure in the tool volume is balanced to hydrostatic pressure by drawing actuation fluid from the reserve volume to the tool volume through a check valve. To set the hanger, a plug is engaged on a seat in the tool, tubing pressure is applied behind the engaged plug, and the seat is unlocked. With more applied pressure, the piston moves, reduces the tool volume, and intensifies pressure of the clean fluid communicated to the hanger's setting mechanism. Over-pressure can be handled by a venting valve.

Abrégé

A system and method are used in drilling a borehole in a formation. A trip to move a drillstring in the borehole is identified, where the trip is expected to produce a piston effect that changes a downhole pressure of the fluid in the borehole. A peak speed to move the drillstring in the borehole is calculated for the trip, and adjustments to a surface backpressure of the drilling system is calculated for the trip at the calculated peak speed to keep the downhole pressure within a tolerance of the formation. The drillstring is moved in the trip according to the calculated peak speed, and the downhole pressure change produced by the piston effect is counteracted by automatically adjusting the surface backpressure according to the calculated adjustments.

A downhole barrier can include a housing disposed between a slip and a seal element, a mandrel extending through the housing and the seal element, and a piston fixed to the mandrel and separating two chambers in the housing. One chamber is positioned between the slip and the other chamber, and is in communication with a passage in the mandrel. The other chamber is in communication with an exterior of the barrier. A system can include a downhole barrier set in a wellbore. The barrier can include a housing disposed between a slip and a seal element, a mandrel, and a piston fixed to the mandrel, the piston separating two chambers in the housing. An outer area of the mandrel in one chamber is equal to twice a difference between an inner area of the housing and an outer area of the mandrel in the other chamber.

Abrégé

For a wellbore drilled in low or subnormal pressure reservoirs, a static loss rate of drilling fluid is monitored within a limit of a drilling rate. Reaching the limit, the annulus is closed off to returns, or the annulus remains open to atmosphere at surface. Operations may not be able to keep the annulus filled with a mud cap so pressurized mud cap drilling cannot be sustained. Instead, an initial fluid level of the mud cap is defined in the annulus. Drilling with the mud cap then involves: pumping a sacrificial fluid through the drillstring without returns to surface, and monitoring the initial fluid level in the annulus to detect a change. Monitoring uses downhole instrumentation to measure pressure, temperature, and gas level of the mud cap. In response to the change, the drilling can be further controlled, including stopping the drilling, turning off pumps, and possibly bullheading the well.

Abrégé

Control of a drilling system drilling a wellbore is improved using a hydraulic model corrected for pressure losses. A surface backpressure of the outlet and a standpipe pressure of the inlet are measured with sensors in the system. An estimate of the standpipe pressure is calculated based integrating from the measured surface backpressure back to the inlet in the hydraulics model. The pressure loss increment in the hydraulics model is calculated based on a difference between the measured and estimated standpipe pressures. Meanwhile, a parameter in the drilling system is monitored during drilling so the parameter can be adjusted at least partially based on the hydraulics model corrected for the pressure loss.
