Method and a system of recovering and processing a hydrocarbon mixture from a subterranean formation
Patent number: 10407621Abstract: The present invention relates to a method and system for recovering and processing a hydrocarbon mixture from a subterranean formation. The method comprises: (i) mobilizing said hydrocarbon mixture; (ii) recovering said mobilized hydrocarbon mixture; (iii) coking said recovered hydrocarbon mixture to produce decoked hydrocarbon and coke; (iv) combusting said coke to generate steam and/or energy and CO2; (v) upgrading said decoked hydrocarbon by hydrogen addition to produce upgraded hydrocarbon; and (v) adding a diluent to the decoked hydrocarbon prior to upgrading and/or adding a diluent to the upgraded hydrocarbon; wherein said method is at least partially self-sufficient in terms of steam and/or energy and diluent.Type: GrantFiled: July 4, 2013Date of Patent: September 10, 2019Assignee: STATOIL CANADA LIMITEDInventors: Knut Vebjørn Grande, Karina Heitnes Hofstad, Harald Vindspoll, Marianne Haugan -
Patent number: 10202550Abstract: A process for the preparation of at least one ARN acid or salt thereof comprising: (I) allowing at least one ARN acid salt to form during the production of crude oil in the presence of water; (II) removing at least 5 wt % of the formed at least one ARN acid salt, e.g. from the oil water interface; and optionally (III) converting said salt into an acid.Type: GrantFiled: December 28, 2015Date of Patent: February 12, 2019Assignee: Equinor Energy ASInventors: Jens Emil Vindstad, Heidi Mediaas, Knut Vebjørn Grande

System and a method of recovering and processing a hydrocarbon mixture from a subterranean formation
Patent number: 9988890Abstract: The present invention relates to a method and system for recovering and processing a hydrocarbon mixture from a subterranean formation. The method comprises: (i) mobilizing said hydrocarbon mixture; (ii) recovering said mobilized hydrocarbon mixture; (iii) deasphalting said recovered hydrocarbon mixture to produce deasphalted hydrocarbon and asphaltenes; (iv) gasifying said asphaltenes in a gasifier to generate hydrogen, steam and/or energy and CO2; (v) upgrading said deasphalted hydrocarbon by hydrogen addition to produce upgraded hydrocarbon; and (vi) adding a diluent to said upgraded hydrocarbon, wherein said method is at least partially self-sufficient in terms of hydrogen and diluent.Type: GrantFiled: July 4, 2013Date of Patent: June 5, 2018Assignee: STATOIL CANADA LIMITEDInventors: Knut Vebjørn Grande, Karina Heitnes Hofstad, Harald Vindspoll, Marianne Haugan -
Patent number: 9856421Abstract: The present invention provides a process for upgrading a heavy hydrocarbon mixture, said process comprising: i) dividing said heavy hydrocarbon mixture into at least a first portion and a second portion, wherein said first portion comprises 10-45% wt of the heavy hydrocarbon mixture and said second portion comprises 90-55% wt of the heavy hydrocarbon mixture; ii) thermally upgrading said first portion of heavy hydrocarbon mixture in an upgrader to produce a lighter hydrocarbon mixture; and iii) mixing said lighter hydrocarbon mixture with a heavy hydrocarbon mixture to produce an upgraded hydrocarbon mixture, wherein, on entry to said upgrader, the composition of said first portion of heavy hydrocarbon mixture is identical to that of said second portion of heavy hydrocarbon mixture.Type: GrantFiled: January 3, 2013Date of Patent: January 2, 2018Assignee: STATOIL PETROLEUM ASInventors: Harald Vindspoll, Knut Vebjørn Grande, Carsten Frithjof Sørlie, Marianne Haugan

Patent number: 9670766Abstract: A steam-based method and system for recovering and processing a hydrocarbon mixture from a subterranean formation. Steam is injected into the subterranean formation to mobilize said hydrocarbon mixture, then the mobilized hydrocarbon mixture is recovered, a self-sufficient diluent is added, and the mixture is separated to produce separated water and separated hydrocarbon. The separated hydrocarbon is deasphalted to produce a deasphalted hydrocarbon and asphaltenes, which is combusted in an oxycombustion process to generate steam and/or energy and CO2, and said the steam is injected into the formation.Type: GrantFiled: July 4, 2013Date of Patent: June 6, 2017Assignee: STATOIL CANADA LIMITEDInventors: Knut Vebjørn Grande, Karina Heitnes Hofstad, Harald Vindspoll, Marianne Haugan
