  • Publication number: 20220292338
    Abstract: A computer implemented method for prediction of geomechanical performance including productivity index decline and completion integrity for a well or a hydrocarbon reservoir using a geomechanics informed machine intelligence (GIMI) algorithm. The method includes running a geomechanical reservoir simulator to generate training datasets for the hydrocarbon reservoir and incorporating physical models and identified variables into the GIMI algorithm. The method further includes training a neural network of the GIMI algorithm by using correlated training datasets that correlate to the physical models to produce a resulting prediction model and performing sensitivity analysis on the resulting prediction model. Additionally, the method includes identifying dominant variables for damage mechanisms through design of experiment statistics and performing history matching and blind test on the resulting prediction model.

  • 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.
