分析一下这个技术：
The THAI™ process combines controlled combustion with vertical and horizontal wells. The simple equation is: air in, upgraded heavy oil out.
To begin the process, bitumen around the “toe” of the horizontal well is heated with steam.Once this approximately three-month heating cycle in a bitumen reservoir is complete, the steam is shut off and air is injected into the vertical well to create a combustion reaction in the reservoir.
Through the controlled injection of air, an estimated two metre thick combustion front begins to move along the horizontal well at about 10 inches (25 centimetres) a day toward the “heel” of the horizontal well. As it heats up, the bitumen drains into the horizontal production well and brought to the surface through natural pressure.
Because the combustion front heats the bitumen to 400 degrees, the oil is also partially upgraded underground. The heat causes a portion of the asphaltine content of the oil to be left behind as coke that is the fuel for the continued combustion.
“It’s an ideal technical solution,” says Chris Bloomer Petrobank’s Chief Operating Officer for Heavy Oil. “Not only does THAI™ allow for a higher recovery of the resource – from 70 to 80 per cent – greenhouse gas emissions are cut by half and there is negligible fresh water use.” Another environmental benefit is a smaller surface footprint and easier reclamation.
从这个过程来看，这个技术属于in-situ 范围。 首先要用到蒸汽 （锅炉）， 然后要用到压缩空气（空压机），期间还要燃烧控制，最后原油被高压气打出。 典型的power engineer 工作的范围。所谓的 smaller surface footprint 部分原因是污染物仍留在地下。所以这个新技术不会影响到POWER ENGUINEER 的就业。所以，power engineer，不光是烧锅炉（水的能量转换过程），还包括其他工质（空气，AMMMONIA等）的能量转换过程，也包括燃烧控制，污染控制，水处理，工质分离等范畴。欢迎讨论。
原来你把我的书捐给了西温图书馆，替我填补了那里的空白，因为我很少有机会跑那么远的。但可别说什么红宝书，称“指南”还比较靠谱。
田园你来加了一层，帖子又上了一层楼。
车行走在路上，一段儿雪很大，树挂银白，地上银白；一段儿路雪下到地上就化了，根本没有积存。素里的雪是比较大的，甚至路边的雪都很深，对这样的景观，我是百看不厌的。望着车窗外景色，忍了半天终于没忍住，回到家不进门，拿着相机专门又去拍照了，直冻得手冰凉才收镜。
但最难熬的时候，也是该有消息的时候了。
