Journal of Applied GeophysicsA hybrid model based on unsupervised learning for seismic response feature extraction and gas-bearing reservoir prediction using longitudinal and transverse waves seismic data in low-degree exploration areas: A case study (6/24): "In low exploration areas (areas with few or no wells), this method is important as
a guide to hydrocarbon exploration."
Response characteristics and novel understandings of dual induction logging of horizontal wells in fractured reservoirs (6/24): "This study can provide response characteristics and novel understandings for the evaluations of horizontal wells in fractured reservoirs...horizontal well technique is important
for oil&gas exploration and exploitation."
A data driven approach to assess the petrophysical parametric sensitivity for lithology identification based on ensemble learning (3/24): "Precise identification of lithology is
significant for oil and gas exploration...The main objective of our study was to determine the best subset of logging features based on available well-log data using SFFS technique for formation lithology identification."
Two-dimensional synchrosqueezing transform and its application to tight channel sandstone reservoir characterization (2/24): "
To facilitate oil and gas exploration and the development of such reservoirs, it is necessary to characterize the lateral characteristics of tight-channel sandstone reservoirs with high precision...Within the scope of this study, we propose a novel TFA approach called TDSST and apply it to the characterization of tight channel sandstone reservoirs."
Variations in the present-day stress field and its implications for hydrocarbon development in the Hassi Terfa field, Hassi Messaoud, Algeria (3/24): "This study aims to provide a new interpretation of the sources and variability of the present-day stress regime and their effect on the development of hydrocarbon resources...This new generation stress map will be beneficial for determining the optimal borehole direction, initiation, and propagation of the hydraulic fracture, and for identifying potentially active faults and fractures in areas with considerable hydrocarbon production. The workflow presented in
this study can be applied to other areas of major hydrocarbon development around the world."
Spectral recomposition feature for optimizing seismic velocity model prediction with a neural network (7/24): "This research contributes significantly to optimizing hydrocarbon exploration by predicting seismic features more accurately."
A novel hybrid CNN–SVM method for lithology identification in shale reservoirs based on logging measurements (4/24): "Precise lithology identification has become a critical issue in the
exploration and development of shale reservoirs...we propose a hybrid CNN-SVM model for lithology identification."
Integration of well logs and seismic attributes for prediction of thermal maturity and TOC content in the Kazhdumi Formation (central Persian Gulf basin) (3/24): "This study proposes an indirect method for estimating source rock properties, specifically thermal maturity and Total Organic Carbon (TOC), using well logs and seismic data within the central Persian Gulf hydrocarbon fields."
Poro-Acoustic Impedance (PAI) as a new and robust seismic inversion attribute for porosity prediction and reservoir characterization (4/24): "Given that porosity is incorporated into the PAI formula, the PAI porosity section and inversion results can be used as an indicator for
evaluating the hydrocarbon capacity of the reservoir. The findings of this research suggest that PAI is an effective attribute for porosity estimation, bridging the gap between seismic data and porosity estimation, thereby enhancing our understanding and exploration of the reservoir."
