this was pretty serious last year.. never kept to update with the situation though.

drsteemer,

Oil Shale contains bituminous solids called kerogens that are released as petroleum-like liquids when the rock is heated to sufficient temperatures (somewhere around 600 to 700 F). Large volumes of water are required to heat the shale in a process called retorting.

One of the more promising processes for extracting oil is the EGL In Situ Retorting process. It involves pumping super heated steam into a closed loop of vertical and horizontal well pipes strategically placed in the oil shale formation. Because it is a closed loop, no fluids are pumped into the formation. After a period of one to four years, the oil shale formation is heated to a sufficient temperature to liquefy and release the oil, where it pools in collection wells to be pumped to the surface. Shale gas, which is similar to natural gas, is also produced in the process.

I just don t understand why they need water to extract oil. Can someone explain to me how to proceed?

I cannot tell you how irate I was when I heard the podcast this morning about using “tainted” water to extract oil from shale… WHAT EXACTLY WILL IT TAKE FOR PEOPLE TO COME TO THEIR SENSES???!!!
It is so easy to miss the point when greed is the only vision that this industry has. GIVE IT UP.
Why on earth would we use tainted water which will be absorbed into the earth in order to prop up an industry that is on its way out??? GET WITH THE PROGRAM. I have serious suspicions with this organization (EARTH SKY.org) who is funded by Monsanto ANYWAY, and now I am convinced that my suspicions are well founded.
