Patent number: 8426498Abstract: A method of introducing a drag reducing polymer into a pipeline such that the friction loss associated with the turbulent flow though the pipeline is reduced by suppressing the growth of turbulent eddies. The drag reducing polymer is introduced into a liquid hydrocarbon having an asphaltene content of at least 3 weight percent and/or an API gravity of less than about 26° to thereby produce a treated liquid hydrocarbon. The treated liquid hydrocarbon does not have a viscosity less than the viscosity of the liquid hydrocarbon prior to treatment with the drag reducing polymer. Additionally, the drag reducing polymer is added to the liquid hydrocarbon in the range from about 0.1 to about 500 ppmw.Type: GrantFiled: August 11, 2011Date of Patent: April 23, 2013Assignee: Phillips 66 CompanyInventors: Stuart N. Milligan, Ray L. Johnston, Timothy L. Burden, Wayne R. Dreher, Kenneth W. Smith, William F. Harris

Publication number: 20120298209Abstract: A system for reducing pressure drop associated with the turbulent flow of asphaltenic crude oil through a conduit. The crude oil has a high asphaltene content and/or a low API gravity. Such reduction in pressure drop is achieved by treating the asphaltenic crude oil with a high molecular weight drag reducing polymer that can have a solubility parameter within about 20 percent of the solubility parameter of the heavy crude oil. The drag reducing polymer can also comprise the residues of monomers having at least one heteroatom.Type: ApplicationFiled: August 11, 2011Publication date: November 29, 2012Applicant: CONOCOPHILLIPS COMPANYInventors: Stuart N.

Publication number: 20120085537Abstract: A method of producing heavy oil by first injecting water and sulfur hexafluoride molecules into a region. The method then introduces electromagnetic waves such as microwaves and/or radio frequencies into the region at a frequency sufficient to excite the water and the sulfur hexafluoride molecules and increase the temperature of at least a portion of the water and sulfur hexafluoride molecules within the region to produce heated water and sulfur hexafluoride molecules. At least a portion of the heavy oil is heated in the region by contact with the heated water and sulfur hexafluoride molecules to produce heated heavy oil. The heated heavy oil is then produced.Type: ApplicationFiled: September 15, 2011Publication date: April 12, 2012Applicants: HARRIS CORPORATION, CONOCOPHILLIPS COMPANYInventors: Dwijen K.

Publication number: 20120061081Abstract: A method of producing heavy oil from a heavy oil formation with steam assisted gravity drainage. The method begins by drilling a borehole into a heavy oil formation comprising a steam barrier between a first pay zone and a second pay zone, wherein the steam barrier prevents a steam chamber to be formed between the first pay zone and the second pay zone. The steam barrier is then heated with a radio frequency. The steam barrier is then fractured to permit a steam chamber to be formed within the first pay zone and the second pay zone. Heavy oil is then produced from the heavy oil formation with steam assisted gravity drainage.Type: ApplicationFiled: September 13, 2011Publication date: March 15, 2012Applicants: HARRIS CORPORATION, CONOCOPHILLIPS COMPANYInventors: Daniel R.
