  • Patent number: 10472946
    Abstract: Aspects of the present disclosure generally relate to attenuating the effects of slugging based on one or more measurements of parameters from one or more locations in one or more wells. In some cases, a controller may be configured to attenuate the effects of slugging based on the one or more parameters, for example, by controlling a choke or an artificial lift. In certain aspects, the one or more locations may include downhole or at the surface of the one or more wells.
    Type: Grant
    Filed: September 17, 2015
    Date of Patent: November 12, 2019
    Assignee: WEATHERFORD TECHNOLOGY HOLDINGS, LLC
    Inventors: Rajan N. Chokshi, Luis E. Gonzales, William C. Lane, David A. Joy

  • Publication number: 20130245953
    Abstract: Methods and apparatus are provided for calculating production of each of a plurality of fractured intervals (or fractures) and monitoring changes in the fracture contribution with time. Such real-time monitoring and analysis may be performed by combining temperature distribution (and pressure) measurements, a real-time surface multiphase flow measurement, and an inflow model for each fractured interval (or fracture). In this manner, the industry may be able to understand the behavior of fractures and, in turn, optimize the number of stages (i.e., fractured intervals), the number of fractures, and the spacing between fractures and stages.
