Patent number: 8091775Abstract: An assembly and process for identifying and tracking assets, such as tubulars, equipment, tools and/or devices. An antenna is electrically connected to a responding device, such as a radio frequency identification device, and this assembly is connected to an asset. The antenna may be positioned about the exterior and/or the interior of the asset and significantly increases the range of signals that may be received and/or broadcast by the responding device. A transceiver may accordingly be positioned a greater distance from the asset without regard to the orientation of the asset and still permit communication between the transceiver and the responding device. In this manner, information that specifically identifies the asset may be compiled in a data base so as to maintain an accurate history of the usage of such assets as tubulars, equipment, tool and/or devices.Type: GrantFiled: March 16, 2010Date of Patent: January 10, 2012Assignee: Marathon Oil CompanyInventor: Joseph A.

Patent number: 7511180Abstract: A process is provided for stabilizing a petroleum liquid feed stream which contains a more volatile hydrocarbon portion, a less volatile hydrocarbon portion and water. The more volatile hydrocarbon portion of the petroleum liquid feed stream is reacted with the water in a fluidized bed heat exchanger to form a solid hydrate and a petroleum liquid product which contains the remaining less volatile hydrocarbon portion of the petroleum liquid feed stream. The petroleum liquid product is separated from the solid hydrate to recover the resulting petroleum liquid product which is substantially less volatile and more stable than the petroleum liquid feed stream and more suitable for storage or transport, particularly at low pressures.Type: GrantFiled: November 19, 2003Date of Patent: March 31, 2009Assignee: Marathon Oil CompanyInventor: John J.

Patent number: 7464760Abstract: A process for inhibiting souring in a hydrocarbon reservoir provides a feed water including a plurality of phosphorous constituents and having an elevated phosphorous concentration. At least some of the phosphorous constituents are removed from the feed water to produce a treated injection water, which has a reduced phosphorous concentration less than the elevated phosphorous concentration. The treated injection water is injected into the reservoir via a first well and the hydrocarbon is produced from the reservoir via a second well. The process inhibits souring in the reservoir insofar as the treated injection water results in a lower level of souring in the reservoir over time than if the feed water had been injected into the reservoir.Type: GrantFiled: March 15, 2006Date of Patent: December 16, 2008Assignee: Marathon Oil CompanyInventor: John E.

Patent number: 7373251Abstract: A method is provided for predicting a value of a designated rock or fluid property in a subterranean geologic volume. A first predicted value of the designated rock or fluid property is also assigned to a volume of a multi-dimensional, multi-scale model. A first predicted value of seismic response for the model volume is calculated from a response model using the first predicted value of the designated rock or fluid property, wherein the response model is responsive to changes in predicted values of the designated rock or fluid property. A synthetic trace is generated and iteratively compared to the corresponding trace obtained from one or more sets of actual seismic data to determine a difference while consistency is maintained between the types, scales and dimensions of values and data.Type: GrantFiled: December 22, 2004Date of Patent: May 13, 2008Assignees: Marathon Oil Company, Compagnie Generale de GeophysiqueInventors: Jeffry G.
