Summary: Seismic reflection is widely used in the oil and gas industry to prospect hydrocarbon resources, and has been used in Brazilian onshore fields to estimate gas accumulations. However, the analysis and interpretation of seismic data are time-consuming due to the large amount of information and noise. To assist geoscientists, a methodology based on convolutional long short-term memory and particle swarm optimization is proposed for detecting gas accumulation. Testing in the Parnaiba Basin shows promising results with an F1-score of 84.22%, sensitivity of 98.06%, specificity of 99.44%, and accuracy of 99.42%.

Summary: The use of data is crucial for various processes such as business and scientific endeavors. However, data consumption can be hindered by sample losses. To address this, we propose a new method that transforms time series into images and utilizes a conditional generative adversarial network (cGAN) pix2pix GAN for imputation. Results indicate that the network outperforms other methods in 50% of the datasets based on ASMAPE and MAE evaluations. Furthermore, the proposed network demonstrates its ability to learn time series features and capitalize on spatial and temporal features for imputation.
