| Application No. | Application Title | Issue Date |
| 20120027516 | METHODS FOR CONSTRUCTING UNDERGROUND BOREHOLE CONFIGURATIONS AND RELATED SOLUTION MINING METHODS Disclosed are methods for solution mining of evaporite minerals, such as trona, comprising drilling an access well and at least two lateral boreholes; injecting a fluid; circulating the fluid through the lateral boreholes with a controlled fluid flow; and collecting a p... | 02/02/2012 |
| 20110175428 | Solution Mining and a Crystallizer for Use Therein In solution mining, holes are drilled parallel to the ground in the ore body to form a series of zigzag channels. These holes are connected to respective holes from the surface to provide a feed and delivery path and a solvent is circulated through the system so as to d... | 07/21/2011 |
| 20110127825 | Traveling undercut solution mining systems and methods In-situ solution mining method of an ore bed, particularly containing trona, which comprises exposing to a solvent an ore region inside a borehole drilled in the ore, and dissolving a desired solute within the exposed region to provide a liquor and create a voided ‘un... | 06/02/2011 |
| 20110080035 | Method and System for Solution Mining A relatively warm mineral deposit is solution mined by injecting fluid through a well drilled into the deposit and dissolving the mineral to form a production brine. Warm production brine is cooled at the surface using a heat exchanger as a crystallizer to precipitate t... | 04/07/2011 |
| 20100225154 | Method for Simultaneously Mining Vertically Disposed Beds 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)... | 09/09/2010 |
| 20100066153 | METHODS FOR CONSTRUCTING UNDERGROUND BOREHOLE CONFIGURATIONS AND RELATED SOLUTION MINING METHODS Disclosed are methods for solution mining of evaporite minerals, such as trona, comprising drilling an access well and at least two lateral boreholes; injecting a fluid; circulating the fluid through the lateral boreholes with a controlled fluid flow; and collecting a p... | 03/18/2010 |
| 20090079255 | Harvesting hydrocarbons from coal, shale, peat and landfill seams A method of extraction of fuels and elements from coal, shale, peat and landfill seams is described which cuts the earth with only a main shaft which could measure half a meter diameter and with auxiliary narrow drillings of, say 10 centimeter diameter, widely spaced fr... | 03/26/2009 |
| 20080122286 | RECOVERY OF BITUMEN BY HYDRAULIC EXCAVATION In one embodiment, a method of hydraulically mining of oil sands from a well pair drilled into an oil sands deposit is disclosed. The wells are preferably installed from a protected underground workspace in or near the producing zone. The method of hydraulic mining disc... | 05/29/2008 |
| 20070221377 | Solution mining systems and methods for treating hydrocarbon containing formations A method for treating an oil shale formation comprising nahcolite is disclosed. The method includes providing a first fluid to a portion of the formation through at least two injection wells. A second fluid is produced from the portion through at least one injection wel... | 09/27/2007 |
| 20070131415 | Solution mining and heating by oxidation for treating hydrocarbon containing formations A method for treating an oil shale formation comprising nahcolite includes providing a first fluid to a portion of the formation. A second fluid is produced from the portion. The second fluid includes at least some nahcolite dissolved in the first fluid. A controlled am... | 06/14/2007 |
