  • Flow control device for a well
    Patent number: 10871057
    Abstract: An apparatus that is usable with a well includes a housing and a body. The housing includes an inlet and an outlet, and a fluid flow is communicated between the inlet and outlet. The body disposed inside the housing to form a fluid restriction for the fluid flow. The body includes an opening therethrough to divert a first portion of the fluid flow into a first fluid flow path; and a first surface to at least partially define the first fluid flow path. The body is adapted to move to control fluid communication through the first flow path based at least in part on at least one fluid property of the flow.

  • System and method for managing temperature in a wellbore
    Patent number: 8727035
    Abstract: A system and a method manage temperature in a wellbore. A thermal barrier may be positioned within the drill pipe and/or the drill collars to obtain a desired downhole temperature and/or control the effect of thermal energy in high-angle and horizontal wellbores. Downhole measurements, such as real-time measurements and/or recorded measurements, may be used to update models, such as steady state models and/or dynamic models. The downhole measurements may validate the static temperature gradient and may provide information about the thermal characteristics of the one or more formations in which the wellbore is located.

  • Method and apparatus for erosion control for use with flow control devices
    Patent number: 8561691
    Abstract: A flow control device for use in a wellbore which has a nozzle with an output to provide a jet of fluid and a structure proximate the nozzle. The structure is positioned a set distance away from the output of the nozzle, where the set distance is greater than a length of a potential core of the jet of fluid.
