Abstract: The present invention is a heat recovery fluid to be used in a closed loop, hot dry rock system, where the fluid remains in a liquid state flowing down from the surface in an annular, downflow conduit to a terminal end heat exchanger. At the terminal end heat exchanger, the heat recover fluid partially vaporizes as a result of indirect heat transfer locally from the geological formation, resulting in a dual-phase fluid or vapor stream flowing out from the terminal end heat exchanger to an axial, return upflow conduit. In one embodiment, the upflow conduit is separated by a single wall from the downflow conduit. When the upflow conduit bears a dual-phase fluid, it has been found that the degree of vaporization of the heat transfer fluid does not result in substantial separation of the vapor and remaining liquid, i.e., which could result in plugging or slug flow in a sloping upward direction, but instead produces a stable flow regime for return of the heated heat recovery fluid to the surface.

Abstract: The present invention is a closed loop system of heat recovery in hot dry rock or in water-containing formations for generation of electrical power. Recovery of heat from such formations is accomplished by way of multiple horizontal levels of generally radially drilled bores from a central shaft. Heat transfer is accomplished either by way of terminal end heat exchangers or by way of heat transfer to conduits extending from the central shaft.

Abstract: The invention comprises a high pressure fluid barrier forming an enclosure boundary with respect to overburden and floor strata separated by one or more production strata containing desirable fluidizable deposits and/or potential reaction materials. A centrally located Super Daisy Shaft delivers a highest pressure fluid to the enclosure boundary by way of envelope conduits extending laterally horizontal and/or downward from the Super Daisy Shaft (or a trench from which such conduits may also extend) into the production strata.

Abstract: The present invention are methods for and products having an elemental sulfur matrix. The matrix is formed by using an amount of shear force on molten elemental sulfur, where the molten sulfur is combined with a matrix forming material.

Abstract: The present invention relates to recovery and treatment of underground mineral deposits by multitude of directional and multi-functional wells drilled from the super daisy shaft through which the dynamics and dragging forces of fluid means is developed synergistically with complex rubblization and other techniques, and more particularly where the same wells assist in creation of the pressurized barriers to contain the exploitation field for treatment and recovery of minerals.

Abstract: The present invention is a process for thermal cracking and reforming of a liquid petroleum stream comprising the liquid petroleum fraction, wherein the liquid petroleum fraction is a substantial portion of the first liquid petroleum stream and has a density equal to or less than about 15° API.

Abstract: Disclosed are systems for removing hydrocarbons from subterranean deposits thereof. A fluid-impervious barrier screen is formed to isolate parts of the deposit or to isolate the deposit from adjacent fluid-permeable earth formations. The barrier screens are formed by fracturing a vertical zone in the formation by micropercussive fracturing or detonation of microexplosive charges in a series of closely-spaced bore-holes to form a vertically extending fractured plane. The fractured plane is sealed with a sealing medium to form a fluid-impervious screen.Hydrocarbons trapped in the enclosed deposit zone are flushed from the formation by recirculating a fluid medium such as superheated brine and/or hot gases through the enclosed deposit zone under sufficient pressure to cause turbulent flow through the pore formations and to relieve the overburden pressure. The flushing medium may be injected in a series of pressure pulses to force the fluid through the pores by hydraulic ramming.
