Publication number: 20230288592Abstract: A system and methods for determining a refined seismic model of a subterranean region are disclosed. The method includes obtaining an observed seismic dataset and a current seismic model for the subterranean region and training a machine learning (ML) network using seismic training models and corresponding seismic training datasets and predicting, using the trained ML network, a predicted seismic model from the observed seismic dataset. The method further includes determining a simulated seismic dataset from the current seismic model and a seismic wavelet, a data penalty function based on a difference between the observed and the simulated seismic datasets and a model penalty function from the difference between the current the predicted seismic models. The method still further includes determining the refined seismic model based on an extremum of a composite penalty function based on a weighted sum of the data penalty function and the model penalty function.Type: ApplicationFiled: March 11, 2022Publication date: September 14, 2023Applicant: SAUDI ARABIAN OIL COMPANYInventors: Daniele Colombo, Diego Rovetta, Weichang Li, Ersan Turkoglu

Publication number: 20230289499Abstract: A system and methods for determining an updated geophysical model of a subterranean region of interest are disclosed. The method includes obtaining a preprocessed observed geophysical dataset based, at least in part, on an observed geophysical dataset of the subterranean region of interest, and forming a training dataset composed of a plurality of geophysical training models and corresponding simulated geophysical training datasets. The method further includes iteratively determining a simulated geophysical dataset from a current geophysical model, determining a data loss function between the preprocessed observed geophysical dataset and the simulated geophysical dataset, training a machine learning (ML) network, using the training dataset, to predict a predicted geophysical model and determining a model loss function between the current and predicted geophysical models. The method still further includes updating the current geophysical model based on an inversion using the data loss and model loss functions.Type: ApplicationFiled: March 11, 2022Publication date: September 14, 2023Applicants: SAUDI ARABIAN OIL COMPANY, Aramco Innovations LLCInventors: Daniele Colombo, Anton Egorov, Ersan Turkoglu

Patent number: 10920585Abstract: In some implementations, airborne electromagnetic (AEM) data and seismic data for a geographic region including sand dunes are received, and the AEM data identifies apparent resistivity as a function of depth within the sand dunes. An inversion with cross-domain regularization is calculated of the AEM data and the seismic data to generate a velocity-depth model, and the velocity depth model identifies velocity variations within the sand dunes. A seismic image using the velocity-depth model is generated.Type: GrantFiled: December 26, 2017Date of Patent: February 16, 2021Assignee: Saudi Arabian Oil CompanyInventors: Daniele Colombo, Gary W. McNeice, Diego Rovetta, Ersan Turkoglu, Ernesto Sandoval Curiel

Patent number: 10577925Abstract: Ground penetrating radar (GPR) measurements from a downhole well tool in a wellbore are obtained to identify length of fractures adjacent the wellbore. A ground penetrating radar transmitter of the downhole tool emits an electromagnetic pulse. The electromagnetic wave of the ground penetrating radar is diffracted on encountering an end or tip of a fracture, which acts as a secondary source. The diffracted signal is then collected by downhole receiver(s) of the downhole tool. Length of the fracture is determined based on the time of travel of the electromagnetic wave from its emission until its collection as a diffracted signal by the downhole receiver(s).Type: GrantFiled: April 25, 2019Date of Patent: March 3, 2020Assignee: Saudi Arabian Oil CompanyInventors: Jesus Manuel Felix Servin, Erika Shoemaker Ellis, Ersan Turkoglu, Howard Khan Schmidt
