However, not all wells offer basic logs such as sonic and density. This kind of information is significant for characterization in reservoir geophysics. This case study proposes a combination of Multilayer Perceptron (MLP) tools that constitute a type of Artificial Neural Network (ANN) and the Ensemble Machine Learning (EML) technique, in the prediction of missing or imputation log data based on the dataset of the Campos Basin. Such machine learning tools are considered robust, fast, and low cost, widely used in several areas. The study explores the combination of MLP and EML in the development of the learning algorithm. The use of MLP was “tuned” with optimal hyperparameters through GridSearch and the EML built through the Voting Estimator technique in a weighted way through the Scikit-learn library. It’s selected well logs like sonic, density, porosity, among other information for training. The velocity profile was selected as the prediction target. The best calculation parameters and errors of ensemble machine learners were generated, and thus, to analyze the generalizability of the algorithms. And finally, the EML Results were compared with the test samples.","PeriodicalId":21695,"journal":{"name":"Second EAGE Conference on Pre-Salt Reservoir","volume":"43 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-09-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84578600","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The project involved 4D feasibility studies, two ocean-bottom-nodes (OBN) surveys and 4D seismic interpretation. Particularly for the Tupi field, but with the promise of serving as a field test for the entire Pre-Salt section, these 4D OBN surveys and studies will hopefully assist to identify oil-bypassed targets for infill wells, optimize the use of intelligent completion valves to improve the reservoir overall sweep and calibrate the water-alternating-gas (WAG) injection cycles to increase oil recovery. Given the technological character of this pilot, it is a huge achievement that time-lapse images reveal the capability of 4D seismic to correctly distinguish discrete fluid variations and its paths through the stiff carbonate reservoirs of Tupi field. The technical-entrepreneurial success of Tupi Nodes Pilot has become a reference for the entire oil industry and already underpins new 4D projects for the Brazilian Pre-Salt. This success reflects the interdisciplinary engagement of geophysicists, geologists and engineers from PETROBRAS Exploration and Reservoir Development areas.","PeriodicalId":21695,"journal":{"name":"Second EAGE Conference on Pre-Salt Reservoir","volume":"47 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-09-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"82093091","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

These scenarios include different geological concepts of matrix and non-matrix types through Single Porosity/Single Permeability (SPSP) and Dual Porosity/Dual Permeability (DPDP) models. Different fluid types ranging from heavy to light hydrocarbon, column heights, and displacement functions are tested. Compositional flow simulations are run to quantify the impact of these scenarios and test the sensitivity to recovery, well rate, water and gas arrivals using primary depletion and secondary recovery of water, gas reinjection, and a combination of both. Moreover, scenarios for miscible CO2 injections are conducted to learn variable impacts on production and reservoir performance. The study produced credible scenarios with an impact on appraisal and development decisions (Estimated Ultimate Recovery/ EUR basis) for CO2-rich gas cap or high CO2 oil outcomes. It also provides guidance, thresholds, and scenarios to support business decision-making when CO2 is encountered including Gas-cap development feasibility and gas management.","PeriodicalId":21695,"journal":{"name":"Second EAGE Conference on Pre-Salt Reservoir","volume":"5 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-09-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"90577304","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
