| 20090111900 | Simple low-pressure fischer-tropsch process - A process for combing carbon monoxide and hydrogen to form liquid fuels such as diesels, and/or waxes, in a single pass fixed bed reactor, at an operation pressure less than 200 psig. The reactor uses a catalyst with a metallic cobalt loading greater than 5% by weight and a rhenium loading of less than 2% by weight, on an alumina support. | 04-30-2009 |
| 20090124713 | Low-pressure Fischer-Tropsch process - A Fischer-Tropsch process for producing diesel fuel or diesel blending stock with a high cetane number, in a concentration of 65-90 wt % at pressures below 200 psia, using a cobalt catalyst with a rehenium and/or ruthenium promoter. The catalyst is a cobalt catalyst with crystallites having an average diameter greater than 16 nanometers, and the resulting hydrocarbon product after a rough flash, contains less than 10 wt % waxes (>C | 05-14-2009 |
| 20090200024 | Modified process for hydrocarbon recovery using in situ combustion - A modified method of in situ recovery of hydrocarbon from an underground hydrocarbon-containing formation. An “L” shaped production well, having a vertical upper section, and a lower horizontally-extending leg which is positioned low in the hydrocarbon formation, is provided. The horizontal leg connects to the vertical section of the production well at a heel portion and has a toe portion at an opposite end thereof. An oxidizing gas is injected into the formation proximate the vertical section of the production well. A vertical combustion front is created which is caused to sweep outwardly therefrom and laterally within the formation above the horizontal leg, from the heel to the toe of the horizontal leg, causing hydrocarbons in the formation above the horizontal leg to be upgraded and liquify, and thereafter to drain downwardly into the horizontal leg which is permeable, where such liquified hydrocarbons are then delivered to surface via production tubing. A non-oxidizing gas is injected into the heel portion of the horizontal leg via injection tubing contained within the vertical section of the production well. Benefits of the modified method of in situ recovery include decreased costs and lessened environmental impact. | 08-13-2009 |
| 20090308606 | Diluent-Enhanced In-Situ Combustion Hydrocarbon Recovery Process - A modified process for recovering oil from an underground reservoir using the toe-to-heel in situ combustion process. A diluent, namely a hydrocarbon condensate, is injected within a horizontal wellbore portion, preferably proximate the toe, of a vertical-horizontal well pair, or alternatively into an adjacent injection well, or both, to increase mobility of oil. | 12-17-2009 |
| 20100096120 | Well liner segments for in situ petroleum upgrading and recovery, and method of in situ upgrading and recovery - A well liner segment for use in hydrocarbon recovery processes. An elongate, typically cylindrical outer liner member, and an inner elongate liner member concentrically located therewithin is provided. Hydrocarbon upgrading catalyst is provided in the interstitial space between the two members. The outer liner members may be threadably coupled together. A slidable seal is provided between the outer liner and the inner liner to accommodated differential thermal growth between the two liners. A process for use of well liner segments having hydrocarbon upgrader catalyst pre-installed therein, is also provided, as is a method for manufacture of a well liner segment. | 04-22-2010 |
| 20110079397 | Jet-drilling and completion process - 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. The method enables fluid injection or production to be undertaken on individual jet-drilled holes or on groups of holes drilled laterally at different vertical intervals in a vertical well within an underground formation. | 04-07-2011 |
