Abstract: A distributed control system can be used to implement failover capabilities for control units that control well equipment during a well operation. For example, a system can include first well equipment that performs a first physical task and second well equipment that performs a second physical task different from the first physical task. Additionally, the system can include a distributed control system with a first control unit coupled to the first well equipment and a second control unit coupled to the second well equipment. Both control units may include a first control module and a second control module for automatically controlling the first physical task and the second physical task, respectively. The distributed control system can detect a failure of the second control unit and initiate a failover process in which the first control unit takes over control of the second physical task by enabling the second control module.

Abstract: Provided is a flowback system and method. The flowback system, in one aspect, include a tank, a transfer pump, a low-pressure vent line coupled between a vent of the tank and a first flare tip, and a high-pressure gaseous hydrocarbon line coupled to a second flare tip. In accordance with yet one other aspect, the flowback system includes a control system including a sensor, a valve and a valve controller coupled to the valve, the valve of the control system coupled between the low-pressure vent line and the high-pressure gaseous hydrocarbon line, the control system configured to sense an unsafe system event and actuate the valve to supply high-pressure gaseous hydrocarbons from the high-pressure gaseous hydrocarbon line to the low-pressure vent line.

Abstract: The disclosure presents processes to improve the calibration of adjustable choke valves corresponding to a specific size of positive choke bean. Typically, manufacturers specify a position of the adjustable choke valve that corresponds to a specific choke bean size. Hydrocarbon fluid conditions and composition vary and subterranean formation characteristics vary which can lead to errors in the calibration. By comparing flow rate parameters of the hydrocarbon fluid flowing through the adjustable choke manifold and the positive choke manifold, errors in calibration can be detected and corrected. The factors involved with the hydrocarbon fluid and the error correction can be used to update a choke model. The choke model can then be used for future calibrations of the adjustable choke valve.

Abstract: The present disclosure describes depth correlation tools and associated methods which do not require wireline depth correlation runs.

Abstract: Tamper-resistant and tamper-evident sample bottles for the transport of pressurized well fluid include sensor packages and data recording devices to characterize and track properties of the sample bottle and its contents.

Abstract: This disclosure may generally relate to operations performed in a wellbore. More particularly, systems and methods may be provided for measuring the position of a tool and/or tubular string downhole. The present disclosure may be able to determine an accurate position change in a downhole tool without requiring surface equipment manipulation during measurement acquisition. A position measurement system may comprise a position measurement tool, wherein the position measurement tool comprises a sensor module and a telemetry module; and a marker, wherein the marker emits a signal measured by the sensor module.

Abstract: A well system and method for wirelessly communicating in a wellbore. The well system may comprise a coil tubing, a transceiver, a secondary transceiver, and an information handling system, wherein the information handling system is configured to record information from the transceiver. A method for wirelessly communicating in a wellbore may comprise disposing a coil tubing into the wellbore, recording a measurement with the transceiver, communicating the measurement from the transceiver to a secondary transceiver, transmitting the measurement from the secondary transceiver to one or more additional secondary transceivers, and retrieving the measurement from the one or more additional secondary transceivers by an information handling system.

Abstract: A stress reactive valve includes a valve body disposed in a subsea safety system or other elongated components of hydrocarbon production systems. The valve body includes a frangible or breakable material such that when the subsea safety system or other elongated system undergoes a stress, such as a bending stress, the frangible valve body can react to the stress by breaking and thereby establishing fluid communication or a fluid path across the valve body. In a first or unbroken condition of the valve body, the valve body prevents fluid communication between a fluid inlet and a fluid outlet. In a second or broken condition of the valve body, fluid communication is allowed between the fluid inlet and outlet. The fluid communication can be used to actuate a device, or the fluid pressure can be used as pilot pressure to actuate a pilot operated valve system.

Abstract: The disclosure provides a well system component configured to reduce excessive acoustic noise that would otherwise interfere with acoustic telemetry systems. Specifically, the well system component includes a body configured to be coupled to a pipe string, at least one lobe extending radially from the body, and a pad disposed on the at least one lobe and extending radially from an outer radial extent of the at least one lobe. The well system component can be installed at critical acoustic transmission locations, such as at the location of a hanger, at or near a flex joint in a wellhead installation, and/or at or near a rig floor or deck of an offshore rig.
