Abstract: 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.

Abstract: A rapid and inexpensive process for increasing the amount of hydrocarbons (e.g., oil) produced and the rate of production from subterranean hydrocarbon-bearing reservoirs by displacing oil downwards within the oil reservoir and into an oil recovery apparatus is disclosed. The process is referred to as “gas-assisted gravity drainage” and comprises the steps of placing one or more horizontal producer wells near the bottom of a payzone (i.e., rock in which oil and gas are found in exploitable quantities) of a subterranean hydrocarbon-bearing reservoir and injecting a fluid displacer (e.g., CO2) through one or more vertical wells or horizontal wells. Pre-existing vertical wells may be used to inject the fluid displacer into the reservoir. As the fluid displacer is injected into the top portion of the reservoir, it forms a gas zone, which displaces oil and water downward towards the horizontal producer well(s).

Abstract: The Portable Renewable Energy System for Enhanced Oil Recovery (“PRESEOR”) is a truck mobile system that reforms biomass into CO2 and hydrogen, following which the gases are separated, with the CO2 sequestered underground for enhanced oil recovery (EOR) and the hydrogen used to generate several megawatts of carbon-free electricity. In contrast to large central power plants that are generally not well-located to support EOR, the small PRESEOR can go directly to the oilfields where it is needed, and do so in a timely manner. The PRESEOR sequesters more biomass-derived carbon than is released by the burning of the oil it yields, thereby producing not only carbon-free electricity but carbon-free oil. Using PRESEOR, over 80 billion barrels of U.S. oil would be made recoverable, without the need to drill new wells in pristine areas.

Coal, tar sands, petroleum-contaminated soil, and/or oil wells that have lost gas pressure can also be desorbed by this in-situ method.
