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.

这项建议涉及热力作业中油井的设计优化。在艾伯塔省和全球各地，热作业用于加热稠密的重油(沥青)，降低它们的粘度，并允许它们以经济的速度流入井筒。热力开采主要有两种技术：蒸汽辅助重力排水(SAGD)和周期蒸汽吞吐(CS)。这些井是在未固结的砂岩储层中钻井的，除非有管子支撑，否则将会坍塌，管子也起到屏蔽层的作用，允许流体通过，但将砂粒留在地层中。这些管式筛管被称为独立筛管衬板，或简称衬板。
