  • Patent number: 8788251
    Abstract: A method for determining flow distribution in a formation having a wellbore formed therein includes the steps of positioning a sensor within the wellbore, wherein the sensor generates a feedback signal representing at least one of a temperature and a pressure measured by the sensor, injecting a fluid into the wellbore and into at least a portion of the formation adjacent the sensor, shutting-in the wellbore for a pre-determined shut-in period, generating a simulated model representing at least one of simulated temperature characteristics and simulated pressure characteristics of the formation during the shut-in period, generating a data model representing at least one of actual temperature characteristics and actual pressure characteristics of the formation during the shut-in period, wherein the data model is derived from the feedback signal, comparing the data model to the simulated model, and adjusting parameters of the simulated model to substantially match the data model.

  • Publication number: 20110289994
    Abstract: A technique enables extending the useful life of tubing deployed in a wellbore. The technique involves routing a damaged or distorted tubing through a straightening device. The tubing straightening device bends and counter bends the tubing along predetermined axes as it passes through the tubing straightening device. The bending and counter bending are selected so the tubing exits the straightening device with a predetermined form.
