    摘要: Method of entailing the simultaneous production of oil and combustion gases using gravity phase segregation and gravity drainage to produce hydrocarbons from a subterranean oil-bearing formation, comprising initially injecting a fluid such as a solvent, steam, or an oxidizing gas through a pair of horizontal wells placed high in the formation and producing oil through a plurality of parallel lower horizontal wells situated low in the reservoir, each lower horizontal well perpendicularly disposed to said upper horizontal wells. In a preferred embodiment well liner segments in lower horizontal wells have apertures therein to allow oil to flow into said lower horizontal wells, at locations where an upper horizontal well traverses a lower horizontal well, possess no apertures to thereby prevent oxidizing gas injected in said upper horizontal wells from flowing directly into said lower horizontal wells at such point at which said lower wells are traversed by said upper wells.

    摘要: A modified method for in situ recovery of hydrocarbon from an underground hydrocarbon-containing formation. An “L” shaped production well, having a vertical section, and a lower horizontal leg positioned low in the formation, is provided. The horizontal leg connects to the vertical section at a heel portion, and has a toe portion at an opposite end thereof. Oxidizing gas is injected into the formation in or proximate the vertical section. A combustion front sweeps outwardly from the vertical section and laterally within the formation above the horizontal leg, from the heel to the toe, causing hydrocarbons in the formation above the horizontal leg to drain downwardly into the horizontal leg, which are then delivered to surface via production tubing. A non-oxidizing gas is injected into at least the heel portion and preferably additional portions of the horizontal leg via injection tubing contained within the vertical section of the production well.

    摘要: A method and apparatus for eliminating COS and/or CS2 from a hydrocarbon-containing feed stream, and further eliminating H2S from such feed stream or converting all sulfur species in such feed stream to H2S and SO2 to allow for easy subsequent conversion of such H2S and SO2 to elemental sulfur in a Claus reaction. The method comprises: (i) injecting water so that the feed stream contains greater than 10 vol % (water equivalent); (ii) passing the feed stream through catalyst means which hydrogenates COS and/or CS2 to H2S; (iii) injecting O2 so that the stoichiometric ratio of O2 to H2S is at least 0.5:1.0; (iv) passing the stream though a reaction zone having oxidation catalyst means which oxidizes H2S to elemental sulfur or SO2 (depending on the amount of oxygen and water added); where the temperature of the reaction zone is above the elemental sulfur dew point.
