  • Patent number: 11828171
    Abstract: A method is described for predicting and preventing wellbore interactions at wells that are near the injection well. The method includes receiving fiber optics data; performing object detection by detecting object-like events in the fiber optic data; and sending instructions to a hydraulic fracturing system based on the object detection. The method is executed by a computer system.

  • Publication number: 20230237223
    Abstract: Methods, systems, and non-transitory computer readable media for estimating well interference on a target well from other potential wells in a subsurface volume of interest are disclosed. Exemplary implementations may include: obtaining well implementation data for the target well and the other potential wells; obtaining estimated reservoir volumes as a function of position; generating well overlap between the target well and the other potential wells; generating extraction interference probabilities; generating a representation of a well layout as a function of position in the subsurface volume of interest; and displaying the representation.

  • Patent number: 11137334
    Abstract: In some embodiments, a system includes a housing having a cavity defined therein for holding a test sample, a first inlet in fluid communication with the cavity to deliver fluid to the test sample, a second inlet in fluid communication with the cavity to deliver fluid to the test sample, the first inlet configured to deliver fluid to the test sample in a direction substantially perpendicular to a direction that the second inlet is configured to deliver fluid to the test sample, an outlet in fluid communication with the cavity to receive fluid from the test sample, and a force applicator configured to apply compressive force to the test sample within the cavity. The force applicator forms a seal with the housing while applying compressive force to the test sample. The system also comprises at least one sensor configured to, while fluid flows from at least one of the inlets through the test sample to the outlet, determine a fluid characteristic, a test sample characteristic, or any combination thereof.

  • Publication number: 20210096277
    Abstract: Embodiments of evaluating production performance for a wellbore while accounting for subterranean reservoir geomechanics and wellbore completion are provided. One embodiment includes generating the wellbore model; defining geomechanical properties for the subterranean reservoir in the near wellbore region and the far field region, and completion variables for the wellbore completion; and simulating fluid flow in the near wellbore region, the far field region, and the wellbore completion to evaluate production performance for the wellbore over a period of time. A permeability of the subterranean reservoir and a contact area between the wellbore and the subterranean reservoir are updated during simulation over the period of time.
