Patent number: 10280726Abstract: A method of solution mining a subterranean mineral ore deposit such as trona ore in which a borehole is drilled from a subterranean mechanically-worked mineral ore mining operation to connect a mineral ore bed to be solution mined, using subterranean drilling apparatus located proximate to the mechanically-worked mineral ore mining operation. The mineral ore bed is isolated from the mechanically-worked mineral ore mining operation by passage of the drilled borehole through an impermeable layer adjacent to the mineral ore bed to be solution mined. The mineral ore bed is then solution-mined using a mining solvent introduced into the mineral ore bed to solubilize the mineral and form a mining solution, and the resulting mining solution is withdrawn from the mineral ore bed.Type: GrantFiled: September 22, 2017Date of Patent: May 7, 2019Assignee: GENESIS ALKALI WYOMING, LPInventor: Michael Bestgen

Patent number: 10144043Abstract: The present disclosure relates to a self-regulating, landfill well control system for automatically controlling a flow of landfill gas (LFG) through a wellhead associated with a landfill well at a landfill. The system has a combination unit operably associated with the wellhead, with a valve actuator, a flow measurement element and a controller. The valve actuator controls a LFG flow control valve, to thus control an LFG flow through the wellhead. The flow measurement element produces differential pressures proportional to a LFG flow rate. The controller controls the valve actuator and, based on data obtained using the flow measurement element, adjusts a setting of the LFG flow control valve to obtain a specific control point setting, and automatically maintains the control point setting thereafter.Type: GrantFiled: April 28, 2015Date of Patent: December 4, 2018Assignee: Q.E.D.
