Protocol for Optimal Size Selection of Punched Screen in Steam Assisted Gravity Drainage Operations

  • Author(s) / Creator(s)
  • Punched screen as a stand-alone screen is gaining more and more popularity in Steam Assisted
    Gravity Drainage (SAGD) operations. However, the literature contains limited studies for proper
    aperture size selection and the performance of the punched screen. This paper aims at investigating
    the performance of punched screen and generating an aperture size selection protocol for SAGD
    production wells.
    In this study, pre-packed sand retention tests (SRT) are conducted to analyze the screen
    performance by using punched screen coupons. These tests incorporate several influential factors,
    including particle size distribution (PSD), flow velocity, and aperture size, into the performance
    analysis. Sanding and flow performance are the two governing factors for the size selection
    protocol. The sanding performance guides the upper limit of the safe size window, and flow
    performance indicates the lower limit. Therefore, the optimal size window is determined to obtain
    desirable sanding and flow performance. In this paper, the size selection protocol is illustrated to
    show the optimal size window of the punched screen.
    This paper presents an optimal size selection protocol for SAGD production wells. The protocol
    can be used by SAGD operators to obtain the proper aperture size for punched screen to maximize
    production rates and profits
