Patent number: 11555381Abstract: A method of conveying a production fluid from an offshore subsea well to an offshore vessel includes deploying an inflatable bladder from the offshore vessel, the inflatable bladder including a bladder valve, and fluidly connecting the inflatable bladder to an offloading port positioned at a seafloor, wherein the offloading port includes a port valve and is in fluid communication with one or more subterranean hydrocarbon-bearing formations. The method further includes opening the bladder and port valves to discharge the production fluid from the offloading port into the inflatable bladder, and thereby resulting in a substantially filled bladder, closing the bladder and port valves, and fluidly disconnecting the substantially filled bladder from the offloading port.Type: GrantFiled: January 10, 2022Date of Patent: January 17, 2023Assignee: ExxonMobil Upstream Research CompanyInventors: Deborah J. Davis, Sushil K. Mandot, David A. Baker, Zhen Li, Brian J. Fielding

Patent number: 9631437Abstract: Systems and methods for managing pressures present in an annular space defined between casing strings contained within a subterranean well. These systems and methods may include providing a pressure distribution casing that includes a plurality of pressure distribution passages and distributing fluids present within the annular space along a length of the pressure distribution casing and/or between the annular space and the subterranean formation using a portion of the plurality of pressure distribution passages. Pressure distribution passages may be present on an inner surface of the pressure distribution casing, on an outer surface of the pressure distribution casing, and/or within a wall of the pressure distribution casing and may distribute the fluids along the length of the pressure distribution casing without distributing the fluids across and/or through a wall of the pressure distribution casing, such as between the inner surface and the outer surface of the pressure distribution casing.Type: GrantFiled: December 6, 2011Date of Patent: April 25, 2017Assignee: ExxonMobil Upstream Research CompanyInventors: Bruce A.

Patent number: 9624750Abstract: A bridge plug arrangement includes a plug having an upper end and a bottom end. The bridge plug arrangement also optionally includes a cylindrical seat. The bridge plug arrangement further includes a tubular member. The tubular member may be part of a casing string. The tubular member is configured to receive the plug and, when used, the seat. The plug and/or the seat may be fabricated from a frangible material. Also disclosed is a method for diverting fluids in a wellbore using the bridge plug arrangement. The method may include landing the plug onto the seat within the wellbore below a subsurface zone of interest. Treatment fluids are then injected into the wellbore, where they are diverted through perforations and into a formation. The plug and/or seat is then optionally broken into a plurality of pieces through use of a downward mechanical force.Type: GrantFiled: April 13, 2010Date of Patent: April 18, 2017Assignees: EXXONMOBIL UPSTREAM RESEARCH COMPANY, RASGAS COMPANY LIMITEDInventors: Pavlin B.

Patent number: 9187965Abstract: A method associated with the selection of tubulars for hydrocarbon production is described based upon evaluating the performance limits of threaded connections. Constituents of an evaluation group of threaded connections are determined and then a first group of the connections is evaluated via model analysis over a range of conditions. Then, physical testing on a first group of threaded connections in the evaluation group is conducted over that range of conditions. Once modeled, the results from the physical testing and the modeling analysis of the first group are compared to assess a characteristic performance factor for the first group. A second group of threaded connections are determined and the assessed performance factor from the first group is applied to a second group, and the performance limits of the second group are defined over the range of conditions based on this characteristic performance factor, without requiring testing the second group.Type: GrantFiled: October 17, 2013Date of Patent: November 17, 2015Assignee: ExxonMobil Upstream Research CompanyInventors: A. S. David Khemakhem, Mark W. Biegler, David A. Baker, Jason A. Burdette, Bruce A. Dale, John W. Mohr, Ismail Ceyhan, James Powers, James H. Myers, Marcus Asmann

Patent number: 8812175Abstract: An orientation-based wireless sensor includes a transmitter unit having a body housing a microprocessor, a transmitter, and an accelerometer for detecting the orientation of the transmitter unit relative to one-, two- or three-axis of the direction of the pull of earth's gravity. The transmitter body is mounted on a feature of a vehicle that it is desirable to monitor. The transmitter will transmit orientation data at predetermined time intervals to a receiver on the vehicle, which will in turn process the information, adding additional information, such as GPS location, and wirelessly send the data to a database that is available to a customer over the Internet.Type: GrantFiled: August 14, 2012Date of Patent: August 19, 2014Assignee: Lat-Lon, LLCInventor: David A.

Patent number: 8590641Abstract: A method associated with the selection of tubulars for hydrocarbon production is described. In particular, the method is associated with the evaluation of performance limits of threaded connections. In this method, constituents of an evaluation group of threaded connections are determined via model analysis. Then, physical testing on a first group of threaded connections in the evaluation group is conducted. Modeling analysis on the first group and a second group of threaded connections is performed, wherein the second group are not physically tested. Once modeled, the results from the physical testing and the modeling analysis are compared to assess a characteristic performance factor for the first group. Then, the characteristic performance factor is applied to the second group, and the performance limits are defined based on this characteristic performance factor.Type: GrantFiled: November 20, 2006Date of Patent: November 26, 2013Assignee: ExxonMobil Upstream Research CompanyInventors: A.
