摘要 |
A method of solution mining vertically disposed beds of water-soluble deposits comprising a lower bed and at least one upper bed having at least one non-soluble layer disposed therebetween, said method comprising the steps of: (a) forming a channel in the lower bed; (b) drilling at least one zero radius or ultra-short radius injection pathway in the at least one upper bed; (c) manipulating at least one of the channel and the at least one injection pathway such that a fluid pathway is established between said channel and at least one injection pathway; (d) injecting a stream of solvent through the at least one injection pathway; and (e) recovering the solvent containing dissolved deposit therein via a recovery well.
