Abstract: The disclosed embodiments include a coupler assembly and method for conveying a single piece liner hanger body. In one embodiment, the coupler assembly includes a nut, a load transfer sleeve, a locking dog retainer, a garter spring, a locking dog, a collet, an outer collet mandrel, and a collet prop mandrel. As described herein, components of the coupler assembly are assembled and installed within the inner diameter of the single piece liner hanger body for engaging with a liner hanger sub-assembly attached to a miming tool.

Abstract: A downhole coupling system for joining together two segments of a tool string includes two mandrels, each having an interlocking interface at an end that abuts the adjacent mandrel and to communicate torque from one mandrel to the next. Each of the mandrels includes a threaded exterior surface, with the threaded surfaces have opposing thread directions or differing thread pitches. The coupling includes mating internal threads. A plurality of axial grooves is formed in each of the interior surface of the coupling and the exterior surface of one of the mandrels. A keyed latch ring having a plurality of internal keys and a plurality of external keys is included to engage the axial grooves, thereby rotationally locking the coupling relative to the first mandrel and second mandrel.

Abstract: A system of monitoring a black cell environment using sensors is presented, in which the sensors can be easily replaced during a sealed period of the black cell environment. The black-cell monitoring system includes at least one sealed vessel that is disposed within the black cell environment. The vessel is configured to store a hazardous mixed substance and is sealed from the external environment for a pre-determined amount of time. The black-cell monitoring system also includes at least one tubing that extends from the outside of the vessel to the inside of the vessel. The black-cell monitoring system also includes a fiber optic cable that is disposed within the lumen of the tubing. At least a portion of the fiber optic cable is disposed within a portion of the tubing located inside the sealed vessel.

Abstract: Systems and methods of production control are contemplated in which one or more multiphase flow meters are operationally coupled to a production conduit to provide flow and compositional information for the fluid in the production conduit. Data from the multiphase flow meter are then provided to a control system that uses the data to control operation of one or more choke valves of one or more well heads that are fluidly coupled to the production conduit.

Abstract: An analog-to-digital metering circuit includes a first programmable gain amplifier to amplify a first voltage signal from a first channel before being received by a first analog-to-digital converter that converts the amplified first voltage signal to a first digital signal. A second programmable gain amplifier amplifies a second voltage signal from a second channel and feds the amplified signal to a second analog-to-digital converter that converts the amplified second voltage signal to a second digital signal. A first lowpass filter circuit receives the first and second digital signals, to generate therefrom, a multi-bit analog-to-digital value. A direct digital synthesizer generates a digital signal representing a predetermined waveform that is fed to a digital-to-analog converter. The second voltage signal and the digital signal representing the predetermined waveform are multiplied together to generate a digital value.

Abstract: A reversible ratchet wrench utilizing two pawls that mesh with teeth inside a housing. The design allows for engagement of all the teeth on a pawl with all the teeth in the housing. The invention provides for reduced stress on the individual teeth of the pawl as compared with a traditional reversible ratchet wrench. Smaller components of less expensive material may subsequently be utilized, allowing for a reduction in housing size.Both a round head reversible ratchet wrench and a pear head reversible ratchet wrench are contemplated. The wrenches of the present invention share several common components. Interchangeability is desirable due to the reduction in required components, and the reduced costs associated therewith.
