| A method is provided for applying a thermal process to a lower zone underlying an overlying hydrocarbon zone with thermal energy from the thermal process mobilizing oil in the overlying zone. The lower zone itself could be a hydrocarbon zone undergoing thermal EOR. Further, one can economically apply a thermal EOR process to an oil formation of low mobility and having an underlying zone such as a basal water zone. Introduction gas and steam, the gas having a higher density than the steam, into the underlying zone displaces the basal water and creates an insulating layer of gas between the steam and the basal water maximizing heat transfer upwardly and mobilizing viscous oil greatly reducing the heat loss to the basal water, economically enhancing production from thin oil bearing zones with underlying basal water which are not otherwise economic by other known EOR processes. | ||||||

| A method for recovering hydrocarbons from a subterranean reservoir by operating a substantially gravity-controlled recovery process with two adjacent well pairs. Each well pair includes an injector well and a producer well. A mobilized zone forms around each well pair through the gravity-controlled recovery process, and a bypassed region forms between the adjacent well pairs when the respective mobilized zone of each well pair merge to form a common mobilized zone. A plurality of infill producer wells are provided in the bypassed region. The plurality of infill producer wells are operated to establish fluid communication between the plurality of infill producer wells and the common mobilized zone. Once fluid communication is established, the plurality of infill producer wells and the adjacent well pairs are operated under a substantially gravity-controlled recovery process, and hydrocarbons are recovered from the plurality of infill producer wells and from the producer wells. | ||||||

The method comprises detecting physical properties of subsurface formation and injection of a flooding agent into said formation through at least one injection well thus forcing reservoir oil movement toward at least one production well. The flooding agent is a highly dispersed gas-liquid mixture having size of gas bubbles not exceeding an average diameter of the pores of said oil-bearing reservoir.

| 175 | METHOD AND APPARATUS TO ENHANCE OIL RECOVERY IN WELLS | US12763650 | 2010-04-20 | US20100276146A1 | 2010-11-04 | David Randolph Smith |
| The present invention provides methods and apparatuses for the enhanced recovery of hydrocarbon fluids from subterranean reservoirs using cryogenic fluids. Using the Earth's geothermal energy to warm cryogenic flood fluids injected into subterranean reservoirs, the pressure within the subterranean reservoir is increased. Consequently, the reservoir conductivity is enhanced due to thermal cracking, and improved sweep efficiency of the reservoir by the flood fluids is provided. This rise in pressure due to the injection of the cryogenic fluid increases the reservoir conductivity enhancement and improves sweep efficiency of the flood fluids, which leads to the production of more fluids from to the subterranean reservoirs. | ||||||

| An apparatus is provided for suction of a secondary fluid into a primary fluid through one or multiple gaps in contact with a venturi. The venturi imparts a high velocity on the primary fluid to flow across a gap in contact with the venturi and draw in the secondary fluid. The apparatus employs a linear venturi with the flow area, or opening, in the form of a narrow ring or narrow rectangle to increase the length of the gap in contact with the venturi. One gap is provided and positioned in contact with one side of the narrow venturi opening, or two gaps are provided having one positioned in contact each side of the narrow venturi opening. The linear venturi is housed in assemblies referred to as “eductors.” Various eductor embodiments are provided including: 1), cylindrical housings with one or multiple concentric linear venturi with openings in the form of narrow rings; 2), rectangular housings with a single rectangular linear venturi with an opening in the form of a narrow rectangle, with multiple rectangular linear venturi with inlets positioned around a primary fluid inlet to flow radially outward through the multiple venturi, with multiple rectangular linear venturi with outlets positioned around a mixing chamber to cause circulation of the flow of fluids; 3), a cylindrical housing with linear venturi with an opening in the form of a narrow ring adapted for inserting into piping; and 4), cylindrical housings with linear venturi with an opening in the form of a wide ring adapted for installation in piping. | ||||||

| 178 | Methods and Apparatuses For Enhanced In Situ Hydrocarbon Production | US12374190 | 2007-06-18 | US20100096147A1 | 2010-04-22 | John Nenniger; Emil Nenniger |
| A process for recovering hydrocarbons from an in situ formation. The process includes the steps of injecting solvent though an injection well into an underground extraction chamber having a hydrocarbon extraction interface, warming the hydrocarbons at the extraction interface to cause the hydrocarbons to flow downwardly by gravity drainage. Barrier gases naturally emerge in the chamber as a result of the extraction process and are removed from the extraction interface to improve heat transfer from said solvent to said interface. The last step is to recover liquids such as hydrocarbons and water through a production well. The invention provides a separate flow path to remove hydrocarbon gases from the chamber at a preferred location. The preferred location is near the top of the chamber where the accumulated barrier gases help to limit the heat loss and can also provide a barrier to help maintain chamber integrity and confinement. | ||||||
