For future reference the Mt. Simon formation is too dense moving eastward and too shallow in Indiana (+600 M).

Secondly, some of the oxides may become carbonates and change density etc. Will that not lead to unpredictable consequences? Or am I being too 'laymanish'?Lhttps://www.blogger.com/profile/03186014514110985045noreply@blogger.comtag:blogger.com,1999:blog-5859094080858570248.post-70543275134339181412012-05-06T09:17:23.973+05:302012-05-06T09:17:23.973+05:30Anon- the article i have linked makes the same poi...Anon- the article i have linked makes the same point that the potential of this technique will be diminished in areas where there are shale gas resources..<br /><br />yes, i think as a stable storage, both basalt and serpentinites are being considered as possible host rock materials..but are these host rocks as widely distributed as deep saline aquifers?..basalts especially tend to be concentrated in provinces.. and sepentinite terrains are narrow and usually highly fractured and faulted, plus the economics of transporting and drilling into these hard rocks might influence the widespread use of these hosts..Suvrat Kherhttps://www.blogger.com/profile/18281172632784780810noreply@blogger.comtag:blogger.com,1999:blog-5859094080858570248.post-33039609096225399792012-05-06T08:20:42.756+05:302012-05-06T08:20:42.756+05:30But aren't all these sites places that have be...But aren't all these sites places that have been hydrofrac'ed in the process of getting the resources out? It seems likely that these will be pretty leaky. Wouldn't it be better to pump it into something reactive like basalt or serpentinite that will precipitate carbonates?Anonymousnoreply@blogger.com
