  • Patent number: 11512573
    Abstract: A method for performing a fracturing operation in a subterranean formation of a field. The method includes obtaining, during the fracturing operation, distributed optical fiber data from a downhole sensor of a treatment well in the subterranean formation, and determining, based on the distributed optical fiber data, an active perforation location from a number of pre-determined perforation locations of the treatment well. The active perforation location is a location of fluid flow into the subterranean formation during the fracturing operation. The method further includes generating, based at least on the active perforation location, a fracturing model for the subterranean formation, and performing, based on the fracturing model, modeling of the fracturing operation to generate a modeling result.

  • Patent number: 10883346
    Abstract: A method of performing a perforation operation is disclosed. The method involves generating a stress contrast distribution for each stage of a well based on drilling stress data and a stress log of the well, generating a stress association between the drilling stress data and the stress log, generating a new stress contrast distribution for each of the stages of a new well based on new wellsite data (new drilling stress data) and the stress association, generating a production forecast using the geometric completion (GC) design and a predicted production forecast based on the engineered completion (EC) design, comparing a cost of a new stress log of the new well with a change in revenue between the GC production forecast and the predicted production forecast, and selectively perforating the new well using either GC or EC design based on the comparing, whereby stress logging may be selectively performed.

  • Publication number: 20170114616
    Abstract: Methods may include applying a correlation between the probability of stress variations in a first well and variations in drilling data obtained from the first well to drilling data obtained from one or more additional wells; calculating a proportion of high stress and low stress contrast stages within the one or more additional wells; and creating one or more synthetic stress profiles for various completion techniques based on the calculated proportion of high stress and low stress contrast stages within the one or more additional wells; and using the one or more synthetic stress profiles to create a synthetic stress log for a geometric completion (GC) and an engineered completion (EC).
