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.

摘要： In an underground oil reservoir, an injection well is completed low in the reservoir and a production well is provided having a horizontal leg completed relatively high in the reservoir and a vertical leg completed low in the reservoir. Water is injected with the vertical leg open and the horizontal leg closed, so that a displacement front advances in an under-riding manner between the wells and oil is produced through the vertical leg. Once the water break-through in the vertical leg occurs, it is closed and the horizontal leg is opened. A rising, horizontal, gravity-stable displacement front then advances upwardly toward the horizontal leg, through which oil is produced. The open horizontal leg acts as a low pressure sink to induce the horizontal displacement front to advance up toward it. This two-stage process is characterized by a good vertical and lateral sweep. In a slightly modified version, water is injected with the vertical leg closed and the horizontal leg open so that a gravity-stable displacement front advances both laterally and vertically with a relatively upright position of a displacement front. In this version (one stage process) the process is also characterized by a good vertical and lateral sweep.

摘要： An in situ combustion process entailing the simultaneous production of liquids and combustion gases that combines fluid drive, gravity phase segregation and gravity drainage to produce hydrocarbons from a subterranean oil-bearing formation, comprising initially injecting a gas through a horizontal well placed high in the formation and producing combustion gas and oil through parallel and laterally offset horizontal wells that are placed low in the formation. wherein the reservoir exploitation proceeds with sequential conversion of production wells to injection wells in a line-drive mode of operation. The process may also be employed without in situ combustion, using instead a gaseous solvent or steam injection.

摘要： A method of drilling a slim hole and inserting a slotted liner into such hole drilled in an underground reservoir using jet-drilling. The method enables jet-drilling to be effective in unconsolidated subterranean formations, such as some petroleum reservoirs.
