This proposal relates to the design optimization of petroleum wells in thermal operations. Thermal operations are used in Alberta and around the globe to heat thick heavy oils (bitumen), reduce their viscosity and allow their flow into the wellbore at economical rates. There are two major technologies for thermal operations: Steam Assisted Gravity Drainage (SAGD) and Cyclic Steam Stimulation (CSS). These wells are drilled in uncemented sand reservoirs and will collapse unless supported by pipes which also act as screens that allow the passage of fluids, but keep the sand grains in the formation. These pipe screens are called stand alone screen liners, or simply liners.

该提案涉及热力作业中油井的设计优化。艾伯塔省和全球各地都使用热操作来加热稠重油（沥青），降低其粘度并使其以经济的速率流入井眼。热力运行有两种主要技术：蒸汽辅助重力排水（SAGD）和循环蒸汽刺激（CSS）。这些井是在未胶结的砂岩储层中钻探的，除非有管道支撑，否则就会塌陷，管道也充当允许流体通过的屏障，但将砂粒保留在地层中。这些管道筛管称为独立筛管衬垫，或简称为衬垫。
