Patent number: 11977196Abstract: Systems and methods for automatically tracking multi-Z horizons within seismic volumes are provided. A surface from a plurality of surfaces identified at different depths for a multi-Z horizon within a seismic volume is selected. A seed point corresponding to the selected surface is determined. The selected surface is tracked over new data points through the seismic volume. Tracking each new data point involves comparing a depth of the new data point with depths associated with other surfaces and determining whether the depth of the new data point honors a geological boundary rule for maintaining a relative depth position of each of the plurality of surfaces within the multi-Z horizon, based on the comparison. When the depth of the new data point honors the rule, the selected surface is extended to include the new data point and, when it does not, the new data point is discarded.Type: GrantFiled: July 31, 2020Date of Patent: May 7, 2024Assignee: Landmark Graphics CorporationInventors: Jocelyn Chan, Nam Xuan Nguyen, Kainan Wang, Xuewei Tan

Publication number: 20240118150Abstract: The present disclosure provides a method for testing an internal force increment of an arch bridge suspender by inertial measurement, including the following steps: (1) selecting a suspender to be tested with internal force increment, and mounting an acceleration sensing device or a speed sensing device at a lower edge of the suspender to be tested; (2) setting an appropriate sampling frequency and collecting signals; (3) processing information data collected in step (2) by using Formulas; and (4) recording a result of the information data processing and obtaining the internal force increment of the suspender. The method can obtain the internal force increment of the suspender by collecting acceleration or speed signals of the lower edge of the suspender and performing calculation from the signals. This method has the advantages of simple and convenient testing, high replicability and low test cost.Type: ApplicationFiled: October 8, 2021Publication date: April 11, 2024Inventors: Hua Wang, Longlin Wang, Tianzhi Hao, Zehua Xie, Mengsheng Yu, Xiaoli Zhuo, Yuhou Yang, Jiejun Ning, Xirui Wang, Xi Peng, Kainan Huang, Junhong Wu

Patent number: 11448787Abstract: A fault indicator calculator, a method for determining a fault indicator, and a fault indicator calculating system are disclosed herein. One embodiment of a fault indicator calculator includes: 1) an interface configured to receive seismic data, and 2) a processor configured to scan a manifold-shaped operator through said seismic data at a range of dips and azimuths and calculate fault throws at various orientations of said dips and azimuths independent of determining other fault indicators.Type: GrantFiled: January 11, 2017Date of Patent: September 20, 2022Assignee: Landmark Graphics CorporationInventors: Jesse Mathias Lomask, Kainan Wang, Arnab Saha

Patent number: 11409016Abstract: Strata surfaces can be identified in well logs and correlated across the well logs taking into account manual corrections. For example, a computing device can receive well logs. The computing device can determine multiple stratum-surface correlations based on the well logs. Then, the computing device can receive user input indicating a correction to a particular stratum-surface correlation. Based on the correction to the particular stratum-surface correlation, the computing device can update some or all of the other stratum-surface correlations.Type: GrantFiled: March 8, 2017Date of Patent: August 9, 2022Assignee: Landmark Graphics CorporationInventors: Yang Peng, Ahinoam Pollack, Kainan Wang, Ming-Kang Shih, Krisha Hansel Tracy, Jesse Mathias Lomask

Publication number: 20220164657Abstract: Embodiments of generating a field development plan for a hydrocarbon field development are provided herein. One embodiment comprises generating a plurality of training reservoir models of varying values of input channels of a reservoir template; normalizing the varying values of the input channels to generate normalized values of the input channels; constructing a policy neural network and a value neural network that project a state represented by the normalized values of the input channels to a field development action and a value of the state respectively; and training the policy neural network and the value neural network using deep reinforcement learning on the plurality of training reservoir models with a reservoir simulator as an environment such that the policy neural network generates a field development plan. A field development plan may be generated for a target reservoir on the reservoir template using the trained policy network and the reservoir simulator.Type: ApplicationFiled: November 23, 2021Publication date: May 26, 2022Inventors: Jincong HE, Xian-Huan WEN, Meng TANG, Chaoshun HU, Shusei TANAKA, Kainan WANG

Patent number: 11294085Abstract: Systems and methods for automatically tracking multi-Z horizons within seismic volumes are provided. Seed data for each of a plurality of surfaces of a multi-Z horizon within a seismic volume are obtained. A data hull for each surface is generated based on the obtained seed data. A tracking region within the seismic volume is determined, based on the generated data hull. Each surface of the multi-Z horizon is automatically tracked through the tracking region. Upon determining that one or more of the plurality of surfaces violate at least one geological boundary rule associated with the plurality of surfaces, truncating the one or more surfaces such that each surface of the multi-Z horizon honors the geological boundary rule within the seismic volume.Type: GrantFiled: October 20, 2017Date of Patent: April 5, 2022Assignee: Landmark Graphics CorporationInventors: Nam Xuan Nguyen, Kainan Wang, Xuewei Tan

Patent number: 11220898Abstract: Well logs can be automatically correlated using dynamic warping with descriptors. For example, a computing device can receive user input indicating a manual correlation between a first node in a first well-log and a second node in a second well-log. The computing device can use the manual correlation to automatically determine a combination of descriptors usable to correlate the first node to the second node. The computing device can then perform dynamic warping on other well logs using the combination of descriptors determined by using the first well log and the second well log. This may provide more accurate correlations between well logs.Type: GrantFiled: March 31, 2017Date of Patent: January 11, 2022Assignee: Landmark Graphics CorporationInventors: Ahinoam Pollack, Yang Peng, Kainan Wang, Ming-Kang Shih, Krisha Hansel Tracy, Jesse Mathias Lomask

Patent number: 11079510Abstract: A system and method are provided for correlating well log data and seismic data corresponding to subterranean formations to generate a seismic well tie that preserves blocking schemes associated with the well log data and constraints corresponding to each block of samples. The seismic well tie may be generated by correlating samples of the well log data with the seismic data by shifting at least some of the samples and using the constraint on changes to the sample values to prevent the sample values of each of the one or more blocks of the samples from changing beyond the constraint. In some aspects, the constraints may relate to a constant velocity or a linearly changing velocity within various blocks of the well log data.Type: GrantFiled: February 19, 2016Date of Patent: August 3, 2021Assignee: Landmark Graphics CorporationInventors: Kainan Wang, Jesse Lomask, Felix Segovia
