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

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 -
