This is a simulated dataset of transient well production data. This dataset was used in my Masters thesis at King Abullah University of Science and Technology (KAUST), and it is shared for academic use and research work. The dataset has 100 wells simulated at time steps of 0.2 hours for an entire year. This gives 43,800 observations per well, and grand total of 4,380,000 observations in the entire dataset. The resulting production data is then perturbed with systemic and random gauge errors to better simulate real-world gauge readings. The simulator code used to generate this dataset can be found at: https://github.com/ykh-1992/TransientNodalAnalysis.jl The data consists of three files: - "wells.csv": This file details the input parameters for each simulated well. - "data.zip": This file houses an 850 MB "data.csv" that includes the simulated well production data. - "auxiliary.csv": This file includes information related to the simulation run.
