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.

该建议涉及热作业中石油威尔斯的设计优化。在阿尔伯塔和地球仪周围使用热操作来加热稠的重油（沥青），降低其粘度并允许其以经济的速率流入井筒。热采作业有两种主要技术：蒸汽辅助重力泄油（SAGD）和循环蒸汽吞吐（CSS）。这些威尔斯井是在未胶结的砂岩储层中钻探的，除非由管道支撑，否则这些井将坍塌，管道也起到了允许流体通过但将砂粒保持在地层中的筛网的作用。这些管筛被称为独立的筛衬，或简称为衬。
