摘要
Abstract A method of optimising gas production from condensate well in Oredo field by simulating surface proportional integral derivative controller, downhole transmitter, wellhead and bottomhole chokes is presented. This method overcomes the potential risk of high backpressure imposed on the production tubing by manual choking or other control solutions using wellhead valve. Firstly, a model of Oredo well O7 is constructed with a closed node constituting the reservoir unit and a surface pressure node on the wellhead. An automated pressure integral derivative controller that senses and controls the bottomhole flowing pressure by actuating the wellhead choke is then installed at the wellhead. Measurement input to the auto-controller is delivered via an insitu transmitter. This design approach is successfully applied to the well O7 model through a commercial multiphase simulator on well models and provides a condensate banking monitoring mechanisms with improved production output.
