SAFETY CLUTCH SYSTEM FOR CIRCULATION/FILL-UP/FLOWBACK TOOL
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.

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.

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.

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.

APPARATUS AND METHOD FOR PRESSURE TESTING IN WET SHOE APPLICATIONS
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.

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.

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

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.
