20150329785 | METHOD AND APPARATUS FOR GENERATING AND/OR HYDROTREATING HYDROCARBON FORMATION FLUIDS - Some embodiments relate to a method for producing, from sulfur-rich type IIs kerogen, a sweetened synthetic crude having a sulfur concentration of at most 1% wt/wt, a nitrogen concentration of at most 0.2% wt/wt and an API gravity of at least 30°. Hydrotreating is performed under only low-severity conditions of at most about 350 degrees Celsius and a maximum pressure of at most 120 atmospheres. In some embodiments, the feedstock to the hydrotreater comprises hydrocarbon pyrolysis liquids generated primarily by low temperature pyrolysis of the sulfur-rich type IIs kerogen. For example, the feedstock may be rich in easier-to-hydrotreat heterocyclic species. In some embodiments, it is possible to optimize the pyrolysis process by monitoring relative concentrations of the easier-to-hydrotreat heterocyclics and the harder-to-treat heterocyclics. | 11-19-2015 |
20150210917 | ALKYLTHIOPHENE-RICH COMPOSITIONS, USES THEREOF AND METHODS OF MANUFACTURING THE SAME - Embodiments of the present invention relates to a pyrolysis-derived thiophenic composition having a high concentration of C1 and/or C2 and/or C3 alkylthiophenes. Preferably, the composition is derived from pyrolysis (e.g. by slow, low-temperature pyrolysis) of type IIs kerogen (e.g. of a kerogenous chalk). In some embodiments, the thiophenic composition may be used as an enhanced oil recovery (EOR) fluid. Some advantages of the presently-disclosed alkylthiophene-rich enhanced oil recovery (EOR) fluids are that (i) the alkyl-thiophene fluids have excellent solvency for heavy hydrocarbons, (ii) alkyl-thiophene fluids are insoluble in water; (iii) it is possible to blend the alkyl-thiophene fluids to a density of about 1.0 g/cc which matches extra heavy oils and bitumens and water; (iv) a boiling point of alkyl-thiophenes exceeds that of water, making it possible to inject heated EOR fluid and create steam in situ for steam distillation. Methods of use of the EOR fluid are disclosed herein. | 07-30-2015 |
20150203776 | METHOD AND SYSTEM FOR HEATING A BED OF HYDROCARBON- CONTAINING ROCKS - Hydrocarbon-containing rocks (e.g, mined oil shale or mined coal or tar sands) are introduced into an excavated enclosure (e.g. a pit or an impoundment) to form. a bed of rocks therein, One or more heaters (e.g. molten salt heaters) are operated to pyrolyze kerogen or bitumen of the rocks. In some embodiments, a hydrocarbon reflux loop is maintained within the enclosure to convectively heat the hydrocarbon-containing rocks by boiling hydrocarbon liquids from a reservoir at the bottom of the enclosure so that vapor passes to the top of the enclosure, condenses, and falls back through the bed. Alternatively or additionally, the rocks may be heated by heaters embedded within wall(s) and/or a floor of the enclosure. Some embodiments relate to techniques for upgrading mined coal to recover both hydrocarbon pyrolysis fluids and upgraded coal (e.g. anthracite coal). | 07-23-2015 |
20150184500 | METHOD AND APPARATUS FOR PRODUCING UNCONVENTIONAL OIL AT SHALLOW DEPTHS - An oil production well is drilled into a kerogenous chalk source rock comprising (i) type IIs kerogen and (ii) shallow naturally-occurring unconventional oil derived from the type IIs kerogen that is resident within pore space of the source rock. In some embodiments, the production well is drilled at a location where the geothermal gradient is at least 3 degrees C. per 100 m is present at or near the production well. It is believed that the presence of this geothermal gradient accelerated maturation of the type IIs kerogen of the source rock to convert a portion of the type IIs kerogen into the unconventional oil. In some embodiments, the shallow production well is non-vertical. In some embodiments, at depths that are shallow and within the source rock, the production well is cased and perforated. Oil from the source rock may be produced via the production well and the shallow-depth perforated locations thereof. | 07-02-2015 |
20150176380 | HEATER PATTERN FOR IN SITU THERMAL PROCESSING OF A SUBSURFACE HYDROCARBON CONTAINING FORMATION - Embodiments of the present invention relate to heater patterns and related methods of producing hydrocarbon fluids from a subsurface hydrocarbon-containing formation (for example, an oil shale formation) where a heater cell may be divided into nested inner and outer zones. Production wells may be located within one or both zones. In the smaller inner zone, heaters may be arranged at a relatively high spatial density while in the larger surrounding outer zone, a heater spatial density may be significantly lower. Due to the higher heater density, a rate of temperature increase in the smaller inner zone of the subsurface exceeds that of the larger outer zone, and a rate of hydrocarbon fluid production ramps up faster in the inner zone than in the outer zone. In some embodiments, a ratio between a half-maximum sustained production time and a half-maximum rise time of a hydrocarbon fluid production function is relatively large. | 06-25-2015 |
