Abstract: A suturing device is adapted for sewing two tubular objects together, and includes a suturing aid rod, a plurality of sewing subunits, and two pushing subunits. The suturing aid rod has two carrying portions that are opposite to each other in a first direction. Each of the sewing subunits includes a suture thread, and two suture needles that are respectively connected to two opposite ends of the suture thread. Each of the pushing subunits is slidable relative to a respective one of the carrying portions between an initial position and a puncture position. When the pushing subunits are in the puncture position, one of the suture needles of each of the sewing subunits is adapted to puncture one of the tubular objects, and the other one of the suture needles of each of the sewing subunits is adapted to puncture the other one of the tubular objects.

The systems and methods include a sensor usable to detect a wellbore production volume of a production fluid from the production tubing per unit time, a conveyance, and a controller including a processor. The controller is operable to automatically determine a differential flowrate for locations along the production tubing based on a difference between a recorded flowrate and a modeled flowrate at the locations, determine any of the locations where the differential flowrate is equal to or greater than a predetermined threshold, and control deployment of the conveyance into the wellbore to perform the cleanout operation at any of the determined locations where a change in a wellbore cleanout utility function using the modeled flowrate compared to using the recorded flowrate is equal to or greater than an improvement factor.

Abstract: Systems and methods for performing a gas lift operation using gas to increase production of production fluid through a production tubing in a wellbore. Included is an optical bubble sensor usable to detect bubbles per unit volume of the production fluid in the production tubing. Also included is a pump operable to pump gas into an annulus in the wellbore outside the production tubing, a valve operable to control whether gas from the pump enters the annulus, and a controller comprising a processor. The controller is operable to automatically convert the detected bubbles per unit volume into a gas/liquid saturation index (GLSI) using a transformation function; automatically execute, at designated intervals, a decision function based on the GLSI to either pump or not pump gas into the wellbore; and automatically control the pump and the valve to pump gas into the annulus when indicated by the decision function.

Abstract: An apparatus configured to support a diffuser segment during removal from and installation into an assembly. The apparatus includes a body having two or more supports and at least two clamp rods. The clamp rods each extend from a first end to a second end.

The end clamp has a foot extending into the first side of the clamp rod. A wheel is received within each support. The pocket and the foot of each end clamp releasably retain a diffuser segment and the wheels rotate to allow the diffuser segment to be removed without damaging a surface coating of the diffuser segment.

Abstract: An optical fiber link includes a first pair of fiber cable link including a first up fiber and a first down fiber; a multi-wavelength controller generating a plurality of wavelengths and send the plurality of wavelengths to a first AD-remote sensor station by a first down fiber. The first AD-remote sensor station drops a first number of the plurality of wavelengths for a first number of remote sensors in the first AD-remote sensor station to process, allows the rest of the plurality of wavelengths to pass to a second Ad-remote sensor station, adds the dropped first number of the plurality of wavelengths processed by the first number of remote sensors back to the first up fiber, and sends a first combined wavelengths including the first number of the plurality of wavelengths processed by the first AD-remote sensor station back to the multi-wavelength controller.

Abstract: A system for controlling pressure applied in a well intervention operation using a physics-based model is provided. The system can include a stripper element that includes a pressure retention element for sealing a wellbore during an intervention operation that uses coiled tubing; a stripper circuit that includes a hydraulic actuator to apply a pressure to the pressure retention element; a processing device coupled to the hydraulic actuator that can receive, from the stripper circuit, a feedback signal. The processing device may receive a physical characteristic of a component and then determine, using data from the feedback signal and the physical characteristic, a minimum pressure level to contain wellhead pressure. The processing device may then output a command to cause the hydraulic actuator to change the pressure on the pressure retention element to be the minimum pressure level or within a pre-set deviation of the minimum pressure level.

Abstract: A trim accessory and method of its use that attaches or retrofits to an existing recessed light fixture, and directs or restricts emitted light from the lighting fixture to areas or locations desired by the end user. The trim accessory attaches to the trim, and has a tapered annular panel with an outer surface, an inner surface, an outer edge, an annular inner portion, and one or more retainers along the annular inner portion that retain an outer periphery of the outer-extending trim of the recessed lamp, to secure the trim accessory against the ceiling or other surface using the recessed lighting fixture. The tapered annular panel extends outwardly and upwardly against the ceiling, to blend visually into the undersurface of the ceiling.

Abstract: Computer systems attempt to manage resource pools of a dynamic number of similar resources and work tasks in order to optimize system performance. Work requests are received into the resource pool having a dynamic number of resources instances. An instance-throughput curve is determined that relates a number of resource instances in the resource pool to throughput of the work requests. A slope of a point on the instance-throughput curve is estimated with stochastic gradient approximation. The number of resource instances for the resource pool is selected when the estimated slope of the instance-throughput curve is zero.
