Patent
Royal Dutch Shell, Marathon Oil and Chevron | Date: 2013-09-23

The present invention provides a method for extracting bitumen from an oil sand stream, the method comprising at least the steps of, a) providing an oil sand stream; b) contacting the oil sand stream with a liquid comprising a solvent to obtain a solvent-diluted oil sand slurry; c) separating the oil sand slurry to obtain a first solids-depleted stream and a first solids-enriched stream; d) filtering the first solids-enriched stream obtained in step c) to obtain bitumen-depleted sand and at least a first filtrate; e) separating at least a part of the first filtrate to obtain a second solids-depleted stream and a second solids-enriched stream; and f) contacting at least a part of the second solids-enriched stream from step e) with solvent to obtain a solvent-diluted second solids-enriched stream; and g) separating the solvent-diluted second solids-enriched stream to obtain a third solids-enriched stream and a third solids-depleted stream.


Patent

The present invention provides a method of handling a solvent-containing solids stream in a non-aqueous oil sand extraction process, the method including the steps of: (a) providing a solvent-containing solids stream at a first pressure; (b) depositing the solvent-containing solids stream provided in step (a) as a bed in a vessel; (c) discharging the solvent-containing solids stream from the vessel at a second pressure via an outlet, thereby obtaining a depressurized solvent-containing solids stream; wherein the solvent-containing solids stream in the vessel in step (b) is at a temperature above the boiling point of the solvent in the depressurized solvent-containing solids stream at the second pressure in step (c).

The present invention provides a method of filtering a solvent-containing slurry stream including: (a) providing a solvent-containing slurry stream, the solvent comprising an aliphatic hydrocarbon; (b) depositing the solvent-containing slurry stream provided in step (a) as a filter cake on a filter medium, wherein a top layer of liquid is formed on the filter cake; (c) allowing the top layer of liquid as formed in step (b) to drain through the filter cake such that substantially no liquid remains on top of the filter cake; (d) allowing a gas to partially penetrate into the filter cake thereby obtaining a filter cake with a liquid solvent-depleted top layer; (e) passing liquid solvent through the filter cake with the liquid solvent-depleted top layer as obtained in step (d) thereby obtaining a washed filter cake; (f) removing solvent from the washed filter cake as obtained in step (e) thereby obtaining a solvent-depleted filter cake; and (g) removing the solvent-depleted filter cake as obtained in step (f) from the filter medium.

The present invention provides a method for extracting bitumen from an oil sand feed stream, the method including at least the steps of: (a) providing an oil sand feed stream; (b) contacting the oil sand feed stream with a hydrocarbon solvent thereby obtaining a solvent-diluted oil sand slurry; (c) filtering the solvent-diluted oil sand slurry thereby obtaining a solids-enriched stream and a filtrate; and (d) removing at least a part of the hydrocarbon solvent from the solids-enriched stream thereby obtaining a solvent-depleted solids-enriched stream, wherein in step (d) the at least part of the hydrocarbon solvent is removed from the solids-enriched stream by purging with a gas stream at a gas/solids weight ratio (related to the solids-enriched stream) of at most 3.0%.


Patent
Royal Dutch Shell, Marathon Oil and Chevron | Date: 2013-02-22

The present invention provides a method for extracting bitumen from an oil sand stream that includes the steps of: providing an oil sand stream; contacting the oil sand stream with a liquid comprising a solvent thereby obtaining a solvent-diluted oil sand slurry; separating the solvent-diluted oil sand slurry, thereby obtaining a solids-depleted stream and a solids-enriched stream; increasing the S/B weight ratio of the solids-enriched stream thereby obtaining a solids-enriched stream having an increased S/B weight ratio and a liquid stream; filtering the solids-enriched stream having an increased S/B weight ratio, thereby obtaining bitumen-depleted sand. In another embodiment, the invention is a system for practicing this method.


Patent
Marathon Oil | Date: 2015-10-08

An electromagnetic induction generator for use in a tubular, such as a tubular deployed in a subterranean well during wellbore construction operations, for generating electric current through electromagnetic induction. The electromagnetic induction generator has at least one conductive coil and at least one Halbach array of magnets. One or both of the at least one conductive coil and the at least one Halbach array of magnets is rotated relative to the other to increase the electric current generated. One or more gears may be provided to multiply the generated electric current.


A dedicated hydraulic line for transmission of a signal device capable of generating one or more unique signals to one or more tools within a subterranean well. Each tool can be equipped with a reader device for receiving signals from and transmitting signals to the signal device. Each reader device can control operation of the tool associated therewith if the reader device is programmed to respond to signals received from the control device. Hydraulic fluid used to operate the tool can be conveyed via the dedicated hydraulic line or a separate hydraulic line. A separate hydraulic line can be used to reset the tool.

A nozzle reactor includes a passage having one or more regions with a converging-diverging shape. The nozzle reactor accelerates a reacting fluid to supersonic velocities and mixes it with a feed material. The reacting fluid and the feed material may be pre-heated. The high speed collision between the reacting fluid and the feed material at elevated temperatures causes the materials to react.

An improved hydrocarbon cracking process includes a first reactor such as a nozzle reactor positioned in series with a second reactor such as a tubular reactor. A cracking fluid such as steam or natural gas is reacted with heavy hydrocarbon material in the first reactor. The first reactor may provide a tremendous amount of thermal and kinetic energy that initiates cracking of heavy hydrocarbon materials. The second reactor provides sufficient residence time at high temperature to increase the conversion of heavy hydrocarbon materials to the desired level. The cracking fluid functions as a hydrogen donor in the cracking reactions so that very little of the heavy hydrocarbon material becomes hydrogen depleted and forms coke even if the heavy hydrocarbon material is repeatedly recycled through the process.
