Patent number: 10934821Abstract: A system and method for extracting a resource from a reservoir repeatedly alternates between injecting a fluid and injecting a gas into the reservoir. A rate and/or an amount of each of the fluid and the gas that is injected into the reservoir is defined by a first fluid-and-gas ratio function that designates different ratios as a function of time. The ratios designate the rate and/or the amount of the fluid that is injected into the reservoir to the rate and/or the amount of the gas that is injected into the reservoir. The rate and/or the amount at which the fluid and/or the gas is injected into the reservoir is changed according to the ratios designated by the first fluid-and-gas ratio function as time progresses.Type: GrantFiled: July 24, 2015Date of Patent: March 2, 2021Assignee: Baker Hughes Oilfield Operations, LLCInventors: Naresh Sundaram Iyer, Steven Hector Azzaro, Glen Richard Murrell, Robert Carl Lloyd Klenner

Patent number: 10613488Abstract: System includes one or more processors that are configured to perform iterations of the following until a predetermined condition is satisfied. The one or more processors are configured to select a modified trial schedule. The modified trial schedule is selected based on initial fluid-extraction data and initial trial schedules and, if available, prior modified trial schedules and prior modified fluid-extraction data from prior iterations. The one or more processors are configured to receive modified fluid-extraction data generated by execution of the modified trial schedule with a designated model of the reservoir. The one or more processors are also configured to update the surrogate model with the modified fluid-extraction data and the modified trial schedule. For at least a plurality of the iterations, the modified trial schedule is selected, at least in part, to reduce uncertainty in a sample space as characterized by the surrogate model.Type: GrantFiled: October 26, 2016Date of Patent: April 7, 2020Assignee: General Electric Co.Inventors: Naresh Sundaram Iyer, Steven Hector Azzaro, Glen Richard Murrell, Robert Carl Lloyd Klenner, Panqing Gao

Patent number: 10605054Abstract: A system includes a schedule generator having one or more processors configured to obtain resource extraction parameters for extracting a resource from a reservoir. The resource extraction parameters include well creation parameters associated with drilling wellbores, well stimulation parameters associated with introducing fracturing fluid into the wellbores, and production parameters associated with extracting the resource through the wellbores. The schedule generator selects initial trial schedules having different values of the resource extraction parameters and receives initial resource output data generated by execution of the initial trial schedules with a designated reservoir model. The schedule generator generates a surrogate model based on the initial resource output data and the initial trial schedules and uses the surrogate model to perform iterations of selecting modified trial schedules until a predetermined condition is satisfied.Type: GrantFiled: February 15, 2017Date of Patent: March 31, 2020Assignee: General Electric Co.Inventors: Robert Carl Lloyd Klenner, Eric Robertson, Guoxiang Liu, Naresh Sundaram Iyer, Steven Hector Azzaro

Publication number: 20190186237Abstract: A system includes a steam distributor configured to distribute steam received from a steam generator to multiple injection wells in a well pad for steam assisted gravity drainage (SAGD) resource production. The system also includes one or more processors configured to control the steam distributor to distribute the steam to the injection wells according to a resultant scheme including values representing multiple parameters for the SAGD resource production. The parameters include the allocated quantities of steam, pressures within multiple production wells associated with the injection wells, and time periods that the steam is directed into the injection wells. The one or more processors are configured to determine the resultant scheme by performing multiple iterations of a surrogate evaluation process until a stop criterion is met, and identifying the resultant scheme as the sample scheme of a final iteration prior to the stop criterion being met.Type: ApplicationFiled: August 31, 2016Publication date: June 20, 2019Inventors: Guoxiang Liu, Steven Hector Azzaro, Naresh Sundaram Iyer, Robert Carl Lloyd Klenner, Mahendra Joshi, Gabriel Tse, Glen Murrell

Patent number: 5949593Abstract: Strut joint assemblies which include built-in off-loading capability or mirror support systems allow a user to minimize the friction developed at the ball joint interface. Each strut joint assembly includes an upper ball joint and a lower ball joint. Each of the ball joints is sealed such that an internal compartment is created which can act essentially as an air spring. By raising the air pressure within these compartments, the load on the ball joint is reduced until the joint separates and air pressure alone carries the entire load. By adjusting the pressure to a value just below the separation pressure, the ball can still maintain contact with the ball socket and carry very little of the actual load. At this pressure, the frictional moment that can be generated by the joint is minimized and is, thus, greatly reduced from the frictional moment developed by a joint which is carrying the full gravity load of the mirror.Type: GrantFiled: March 16, 1998Date of Patent: September 7, 1999Assignee: Eastman Kodak CompanyInventor: Carl A.
