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: 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.

Patent number: 8301425Abstract: A method and apparatus for producing hydrocarbons is described. In the method, a failure mode for a well completion is identified. A numerical engineering model to describe an event that results in the failure mode is constructed. The numerical engineering model is converted into a response surface. Then, the response surface is associated with a user tool configured to provide the response surface for analysis of another well.Type: GrantFiled: July 6, 2006Date of Patent: October 30, 2012Assignee: ExxonMobil Upstream Research CompanyInventors: Bruce A. Dale, Rahul Pakal, David C. Haeberle, Jason A. Burdette, John W. Mohr, Darren F. Rosenbaum, Marcus Asmann, Scott R. Clingman, Brian W. Duffy, Timothy G. Benish

Patent number: 8190414Abstract: A method for modeling a reservoir response in a subsurface system is provided. The subsurface system has at least one subsurface feature. Preferably, the subsurface system comprises a hydrocarbon reservoir. The method includes defining physical boundaries for the subsurface system, and locating the at least one subsurface feature within the physical boundaries. The method also includes creating a finite element mesh within the physical boundaries. The finite element mesh may have elements that cross the at least one subsurface feature such that the subsurface feature intersects elements in the mesh. A computer-based numerical simulation is then performed wherein the effects of the subsurface feature are recognized in the response. The reservoir response may be, for example, pore pressure or displacement at a given location within the physical boundaries.Type: GrantFiled: February 6, 2009Date of Patent: May 29, 2012Assignee: ExxonMobil Upstream Research CompanyInventors: Hao Huang, Jing Wan, Marcus Asmann, Bruce A.

Publication number: 20110011595Abstract: Methods for generating a surrogate model for subsurface analysis may include identifying input parameters for the subsurface analysis, and selecting a range of values for the identified parameters. The methods also include selecting a design of experiments method for filling sampling points within the ranges of values for the identified input parameters. The design of experiments method may be a classical method or a space-filling technique. The methods also include filling sampling points within the ranges of values for the identified input parameters. The sampling points are filled based on the design of experiments method selected. The methods further include acquiring output values for each of the selected sampling points, and constructing a surrogate model based upon the output values for at least some of the selected sampling points. The surrogate model is a mathematical equation that represents a simplified model for predicting solutions to complex reservoir engineering problems.Type: ApplicationFiled: March 3, 2009Publication date: January 20, 2011Inventors: Hao Huang, Sheng-Yuan Hsu, Jason A.

Publication number: 20100000740Abstract: A method of completing a well is described. The well may be a producing well or an injection well. In one embodiment, the method includes identifying technical issues associated with a well; selecting a technology to address each technical issue; defining criteria for each selected technology to determine when to deploy the selected technology in the well, wherein each selected technology remains dormant until the criteria are met; and integrating the technologies into a well completion profile stored in. memory and utilized in the deployment of the technologies into the well. The method provides the ability to proactively address technical issues to reduce workovers and interventions for a well.Type: ApplicationFiled: January 9, 2007Publication date: January 7, 2010Inventors: Bruce A.
