Safety Clutch System for Circulation/Fill-up/Flowback Tool
A flowback tool is used on a top drive for delivering fluid flow to a tubular, such as a drillpipe or casing. A mechanical stroke on the tool has a mandrel with a mud saver valve and has a barrel. The mandrel connects to a quill of the top drive and has a coupling that can be threaded with the tubular's box connection. 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 on the barrel is configured to sealably engage with the tubular. A clutch 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.

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.

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.

DEBRIS EXCLUSIVE-PRESSURE INTENSIFIED-PRESSURE BALANCED SETTING TOOL FOR LINER HANGER
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.

A wiper plug is used in an operation to cement tubing in a borehole. The wiper plug is pumped down the tubing to separate an advancing fluid from a following fluid of the cementing operation, and an internal pressure chamber is maintained in a throughbore of the wiper plug between uphole and downhole barriers. The wiper plug eventually lands in the tubing, and the uphole barrier is removed by applying a first predetermined pressure against the uphole barrier. Removal of the uphole barrier is facilitated by the known and controlled internal pressure of the plug's chamber. The downhole barrier is also removed so that flow is permitted through the throughbore of the wiper plug. To perform a tubing pressure test, the downhole barrier can be removed due to pressure, and the chamber may have a temporary valve to hold applied pressure to a test level. Alternatively, the downhole barrier can hold the applied pressure. The temporary valve and the downhole barrier can then be self-removing in response to a stimulus.

Debris exclusive-pressure intensified-pressure balanced setting tool for liner hanger
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.

Measuring component concentrations of nonhomogeneous immiscible mixtures in multiphase flows using near-infrared (NIR) filter photometry
Near-Infrared (NIR) filter photometry is used to calculate component concentrations in multiphase flows. The disclosed methodology adapts the Beer-Lambert law for nonhomogeneous immiscible mixtures (such as oil and water) by modeling the fluid layer as a nonhomogeneous distribution of its components and deriving a mathematical relationship between measured absorbances, component path lengths, and non-homogeneity factors. The methodology is integrated into a multi-channel filter photometer to measure phase concentrations in oil-and-gas pipelines. The system is proven more accurate than current state of the art based on data from simulations, multiphase flow laboratories and field trials.
