Effect of Shear Stress Buildup at the Interface of Sand Control Screen and Oil Sand on the Screen Performance in SAGD

点击翻译按钮获取中文摘要

Steam Assisted Gravity Drainage (SAGD) is the main thermal technique for in situ heavy oil recovery in Canada. This technique employs two horizontal wells that are supported against collapse by the installation of screen liners called Sand Control Devices (SCDs). SCDs are designed to (1) control sand production while allowing the flow of reservoir fluids into the well; and (2) allow the discharge of fine materials to avoid plugging of the screen and pore spaces behind the screen.
