TL;DR: In this paper, a thermally enhanced oil recovery method and apparatus for exploiting deep well reservoirs utilizes electric downhole steam generators to provide supplemental heat to generate high quality steam from hot pressurized water which is heated at the surface.
Abstract: A thermally-enhanced oil recovery method and apparatus for exploiting deep well reservoirs utilizes electric downhole steam generators to provide supplemental heat to generate high quality steam from hot pressurized water which is heated at the surface. A downhole electric heater placed within a well bore for local heating of the pressurized liquid water into steam is powered by electricity from the above-ground gas turbine-driven electric generators fueled by any clean fuel such as natural gas, distillate or some crude oils, or may come from the field being stimulated. Heat recovered from the turbine exhaust is used to provide the hot pressurized water. Electrical power may be cogenerated and sold to an electric utility to provide immediate cash flow and improved economics. During the cogeneration period (no electrical power to some or all of the downhole units), the oil field can continue to be stimulated by injecting hot pressurized water, which will flash into lower quality steam at reservoir conditions. The heater includes electrical heating elements supplied with three-phase alternating current or direct current. The injection fluid flows through the heater elements to generate high quality steam to exit at the bottom of the heater assembly into the reservoir. The injection tube is closed at the bottom and has radial orifices for expanding the injection fluid to reservoir pressure.
TL;DR: In this article, the authors investigated autothermal steam reforming of selected compounds of bio-oil using thermodynamic analysis and derived the optimal O2/fuel ratio to achieve thermoneutral conditions under all operating conditions.
TL;DR: In this article, the simulation and exergy analysis of a hybrid Solid Oxide Fuel Cell-Gas Turbine (SOFC-GT) power system is discussed, and the authors show that an electrical efficiency close to 60% can be achieved using appropriate values of the most important design variables; in particular, the operating pressure and cell current density.

TL;DR: In this article, the authors proposed a combined heat and power cycle combining a gas turbine (GT) and an ORC through a single-pressure heat recovery steam generator (HRSG), and the results revealed that the increase in pressure ratio and isentropic efficiency of air compressor and gas turbine efficiency improves thermodynamic performance of the system, however, the more increase of these parameters deteriorates the total cost rates.
