Patent number: 11137514Abstract: One aspect includes a method for determining a drilling plan for new wells in a reservoir. The method includes categorizing the new wells into at least a first new well and a second new well, such that a drilling location for at least the first new well must be determined imminently, but a drilling location for at least the second new well can be determined at a later time. The method further includes determining potential drilling locations for the second new well, determining the drilling location for the first new well based at least in part on the determined potential drilling locations for the second new well, and outputting the drilling plan comprising the determined drilling location for the first new well and the determined potential drilling locations for the second new well.Type: GrantFiled: January 15, 2018Date of Patent: October 5, 2021Assignees: International Business Machines Corporation, REPSOL, S.A.Inventors: David Echeverria Ciaurri, Sonia Mariette Embid Droz, Eduardo Goncalves Dias De Barros, Ruben Rodriguez Torrado

Patent number: 10832658Abstract: A method, program product and computer system to predict utterances in a dialog system includes receiving a set of utterances associated with a dialog between a client device and a dialog system, mapping the utterances to vector representations of the utterances, and identifying at least one cluster to which the utterances belong from among a plurality of possible clusters. A next cluster is predicted based upon a conditional probability of the next cluster following a set of a predetermined number of previous clusters using a language model. A next utterance is predicted from among a plurality of possible utterances within the predicted next cluster.Type: GrantFiled: March 8, 2018Date of Patent: November 10, 2020Assignee: INTERNATIONAL BUSINESS MACHINES CORPORATIONInventors: Chulaka Gunasekara, David Nahamoo, Lazaros Polymenakos, Kshitij Fadnis, David Echeverria Ciaurri, Jatin Ganhotra

Patent number: 10738599Abstract: Well settings in mature oil field may be configured by generating progressively, geological reservoir models by fitting a set of initial geological reservoir models that generate forecasts of fluid injection and production at a well as a function of time, with a subset of historical well data to produce a set of intermediary geological reservoir models, and fitting the set of intermediary geological reservoir models to a next subset of the historical well data. A set of diverse geological reservoir models may be determined from the geological reservoir models. A mid-term schedule of well settings associated with the well may be generated based on the set of diverse geological reservoir models and an economic model that comprises mid-term estimation of oil sale price and of production costs. The mid-term schedule of well settings may be actuated to control the fluid injection and production at the well.Type: GrantFiled: June 26, 2017Date of Patent: August 11, 2020Assignees: International Business Machines Corporation, LLC “Gazpromneft Science & Technology Centre”Inventors: Vladimir M. Babin, David Echeverria Ciaurri, Maria Golitsyna, David Kremer Garcia, Artyom Semenikhin, Oleg S. Ushmaev, Ramil R. Yaubatyrov

Patent number: 10689965Abstract: A system, method and computer program product for assessing field development plans selected based on a stochastic response surface, preferably, for hydrocarbon reservoir production. Assessment begins by assessing uncertainty associated with multiple decision variable configurations. A subset of realizations is selected. An individual surrogate is constructed for each subset realization. A reduced representative realization subset is determined, where the reduced subset is representative of the behavior/performance of all realizations of decision variable configurations.Type: GrantFiled: June 9, 2014Date of Patent: June 23, 2020Assignees: REPSOL, S.A., International Business Machines CorporationInventors: Sonia Mariette Embid Droz, Ruben Rodriguez Torrado, Mohamed Ahmed Hegazy, David Echeverria Ciaurri, Bruno da Costa Flach, Ulisses T. Mello, Davi Valladao

Patent number: 10678967Abstract: A plurality of development scenarios is determined. At least a first well is drilled at a first location and trajectory that are common to the plurality of development scenarios. A result of the at least one first well is assessed. A first subset of development scenarios is selected from the plurality of development scenarios based at least on the result of the first well. A first sequence of subsequent wells, including at least one well, are drilled at a first sequence of subsequent locations and trajectories that are common to the first subset of development scenarios.Type: GrantFiled: October 21, 2016Date of Patent: June 9, 2020Assignees: International Business Machines Corporation, GAZPROMNEFT SCIENCE & TECHNOLOGY CENTRE LLCInventors: Vladimir M. Babin, David Echeverria Ciaurri, Bruno Da Costa Flach, Arseniy Gruzdev, Miguel Paredes Quinones, Alexander Pozdneev, Artyom Semenikhin, Oleg S. Ushmaev, Andrey M. Vashevnik

Patent number: 10546355Abstract: Configuring well settings may include determining schedules over a mid-term horizon for well settings for all or a subset of wells in an oil field. The schedule may be generated so that a performance metric for the considered horizon is maximized. An economic metric, for example, a net present value, and production metrics, for example, cumulative oil production, are considered. Minimum acceptable short-term and long-term metrics, for example, short-term and long-term cumulative field oil production, may be included as target/constraints.Type: GrantFiled: October 20, 2016Date of Patent: January 28, 2020Assignee: International Business Machines CorporationInventors: Vladimir M. Babin, David Echeverria Ciaurri, Nikolay G. Glavnov, Maria Golitsyna, Ramil R. Yaubatyrov, Alexander Pozdneev, Artyom Semenikhin, Oleg S. Ushmaev
