| Methods for multi-directional enhanced oil recovery (MEOR) are disclosed that involve removal of oil from a reservoir that has an injection well, a producing well, and a plurality of lenses that contain oil and that each span between the injection well and the producing well. One method, among others, involves recovering primary oil from a primary set of lenses via the producing well by alternating injection one or more times of water and an injection gas, or IG (e.g., carbon dioxide, ethane, natural gas, nitrogen, etc., or any combination thereof) into the injection well so that the water and IG enter the primary set in a first direction and move the primary oil in the first direction. The method further involves recovering secondary oil from a secondary set of lenses that is different than the primary set via the injection well by alternating injection one or more times of water and the IG into the producing well so that the water and carbon dioxide enter the secondary set in a second direction that is different than the first direction (e.g., opposite) and therefore move the secondary oil in the second direction. | ||||||

| 134 | Pressure Assisted Oil Recovery | US15395428 | 2016-12-30 | US20170175506A1 | 2017-06-22 | Jason Swist |
| Estimates of global total “liquid” hydrocarbon resources are dominated by structures known as oil sands or tar sands which represent approximately two-thirds of the total recoverable resources. This is despite that the Canadian Athabasca Oil Sands, which dominate these oil sand based recoverable oil reserves at 1.7 trillion barrels, are calculated at only a 10% recovery rate. However, irrespective of whether it is the 3.6 trillion barrels recoverable from the oil sands or the 1.75 trillion barrels from conventional oil reservoirs worldwide, it is evident that significant financial return and extension of the time oil as resource is available to the world arise from increasing the recoverable percentage of such resources. According to embodiments of the invention pressure differentials are exploited to advance production of wells, adjust the evolution of the depletion chambers formed laterally between laterally spaced wells to increase the oil recovery percentage, and provide recovery in deeper reservoirs. | ||||||

| A method for recovering oil from a subterranean, hydrocarbon-bearing formation includes at least one injection well and injecting a carrier fluid including a diverting agent into a high permeability pathway within the formation. An activating fluid is injected into the high permeability pathway within the formation, resulting in the precipitation or swelling of the diverting agent. The permeability of the high permeability pathway is decreased within the formation containing the diverting agent to a permeability less than the permeability of the adjacent areas of the formation. A mineralization fluid may be injected that is oversaturated or becomes oversaturated upon interacting with the acid gas that causes mineral precipitation to seal off high-permeability pathways. | ||||||
