Web2 mrt. 2024 · In order to clarify the characteristics of fine-grained sedimentary lithofacies and the depositional models in lacustrine environments of the Chang 7 Member of the Upper Triassic Yanchang Formation in the Ordos Basin, we focus on the lacustrine lithofacies classification and controlling factors. Based on the typical field sections of the southern … Web1 mei 2024 · For modeling lithofacies, six lithofacies codes have been presented; the codes are as folllows: anhydrite, limestone, dolomite, shale, dolomitic limestone, dolomite with anhydrite. After variography analysis, identified codes have been propagated based on sequential indicator simulation method by considering depositional environment of …
Web1 nov. 2024 · With the latter being my main field of expertise, I have conducted my research in predicting hydrocarbon-bearing units and classification of different lithofacies within the reservoir using different machine learning algorithms. I have a demonstrated history of working in the higher education industry with four years of teaching assistance … WebIn the classification based on the spectral facies, the trained multilayer neural network model showed high prediction accuracy for all the lithofacies. Based on these observations, it is confirmed that more precise lithofacies interpretation and classification can be conducted with the developed methods.
Web3 jun. 2024 · Clustering of data is a common form of exploratory data analysis (EDA) which is used to divide up the data into different groups based on shared characteristics or properties. Data points that are similar to each other are grouped together in the same cluster, and those that are different are placed in another cluster. K-Means Clustering Web6 mrt. 2024 · Interpretation of the environment in which lithofacies were deposited from analysis of cored sequences involves relating the identified lithofacies to the physical and biological processes that produced them. This process-response relationship identifies the specific processes responsible for the sequence and, by inference, the depositional ...
Web27 okt. 2024 · We performed lithofacies classification on different wireline logs using the semi-supervised algorithm. The number of pairwise constraints is a key parameter. Depending on the data structures and complexities, the optimal number of constraints varies. We tested different numbers of constraints of 100, 150, 200 and 250 pairs.
