Steam Assisted Gravity Drainage (SAGD) has become one of the most widely used methods of thermal heavy oil recovery. SAGD wells are typically completed with slotted liners in the horizontal section as sand control devices. It is essential that slotted liners be designed with sufficient structural capacities to withstand installation loads (compression, curvature loading and torque) and operation loads (thermal strain and external formation pressure). Torque is the key installation load that must be controlled to avoid permanent slot deformations. During operations, the slotted liners must be strong enough to withstand thermal strains and strain localization without excessive slot deformations.
This article presents considerations for slotted liner design and reviews the potential deformation mechanisms that a liner may experience during installation and operation. Finite element models were developed to determine slotted liner structural capacities for various load conditions and slot patterns, including a newly developed gang slot pattern.
