    Abstract: A downhole tool for sand fall-back prevention can include a sand bridge inducer configured to be mounted in a flow path through a housing in a downhole tool. The sand bridge inducer can define a longitudinal axis and having a main opening therethrough, wherein the sand bridge inducer includes one or more angled passageways defined through a wall of the sand bridge inducer that are oblique relative to the longitudinal axis. The sand bridge inducer can be segmented with a respective upper segment and lower segment at each respective one of the one or more angled passageways, wherein the respective upper and lower segments are connected to one another across the respective angled passageway for movement along the longitudinal axis relative to one another to enlarge the respective angled passageway for accommodating passage of larger particles and/or relieving pressure differentials caused by high flow rates and/or solids restricting flow.

    Abstract: A system for processing DAS VSP surveys in real-time is provided. The system includes a DAS data collection system coupled to at least one optical fiber at least partially positioned within a wellbore and configured to repeatedly activate a seismic source of energy. The system further includes an information processing system connected to the DAS data collection system. A seismic dataset is received from the DAS data collection system. The seismic dataset includes a plurality of seismic data records. Two or more of the plurality of seismic data records are combined into a stack. A quality metric indicative of a desired signal-to-noise ratio or incoherence of the stack is determined for each processed seismic dataset collected from a repeated source. Instructions are sent to the DAS data collection system to stop activating the seismic source, in response to determining that the quality metric has reached a predefined threshold.

    Abstract: A method for processing distributed acoustic sensing (DAS) vertical seismic profiling (VSP) data is provided. The method includes operations to receive DAS data associated with an optical fiber's response to seismic energy applied by three seismic energy sources. The three seismic energy sources each configured to apply seismic energy to the optical fiber in a direction that is orthogonal to a direction of seismic energy applied by the other two seismic energy sources, the optical fiber is at least partially positioned within a wellbore, and the DAS data includes three components directed in an axial direction of the wellbore associated with energy application by the respective three seismic energy sources. The method further includes operations to apply reciprocity to the three components to model an equivalent vertical point force source in the wellbore with receivers configured to receive the three components at a location of the respective three seismic energy sources.

    Abstract: Some implementations include a method for analyzing cuttings from a plurality of depths while drilling a wellbore in a subsurface formation, the method comprising: obtaining cuttings samples from the plurality of depths while drilling the wellbore in the subsurface formation; performing the following operations for each of the cuttings samples: loading a cuttings sample into a viewing area of a microscope coupled to an image capture device and a computer having a learning machine, performing analyses on the cuttings sample, and capturing, via the image capture device, a plurality of images of the cuttings sample through the microscope. The method further includes outputting a standardized cuttings report generated by the learning machine.

    Abstract: A system may include a lower completion disposed in a main bore of a multilateral well in a position downhole from a junction of the multilateral well. The system may also include a fluid separator configured to receive formation fluid, which includes oil and water, flowing from the lower completion. The fluid separator may be configured to at least partially separate the formation fluid into formation oil and formation water. The fluid separator may also be configured to output the formation oil, via a separator oil outlet, to flow uphole, and output the formation water, via a separator water outlet, to flow toward a lateral bore of the multilateral well. Further, the system may include a water cut sensor disposed uphole from the fluid separator. The water cut sensor may be configured to measure the percentage of water in the formation oil.

    Abstract: A pump fluid end having a reciprocating element a discharge valve assembly, a suction valve assembly, and a suction valve stop. The reciprocating element is disposed at least partially within a reciprocating element bore of the pump fluid end. The suction valve assembly is coupled with a front end of the reciprocating element. The suction valve stop is positioned within the reciprocating element bore such that the suction valve stop contacts and applies a closing force to the suction valve assembly when the suction valve assembly is stuck open at the end of a discharge stroke of the reciprocating element.
