  • Publication number: 20140039860
    Abstract: The present disclosure describes systems and methods for monitoring and diagnosing reservoirs. At least some illustrative embodiments include a method that includes collecting measured near-wellbore data representative of conditions at or near wells within the reservoir (e.g., oil and gas wells), storing the measured near-wellbore data in one or more databases and graphically presenting to a user simulated interwell data generated by a reservoir simulation based at least in part on the measured near-wellbore data. The method further includes graphically overlaying at least some of the measured near-wellbore data over the simulated interwell data and graphically presenting to the user one or more production indicators calculated based at least in part on the simulated interwell data.

  • Publication number: 20140039793
    Abstract: Systems and methods for monitoring, diagnosing and optimizing operation of a gas lift (GL) system, at least some of which include a method that includes collecting measured data representative of the GL system's state, storing the measured data, comparing the measured data to a well model's calculated data for the well and identifying likely conditions of the GL system based on mismatches between the measured data and the calculated data. The method further includes updating the model to reflect the likely conditions and selected corrections of the likely conditions, generating GL system performance curves using the updated model and presenting to a user actions recommended to achieve a GL system performance consistent with a GL system operating point on at least one of the GL system performance curves.

  • Publication number: 20140039836
    Abstract: The present disclosure describes systems and methods for monitoring, diagnosing and optimizing operation of an electric submersible pump (ESP).
