Real-time prediction method of borehole stability
Petroleum Exploration and Development, 2008 Based on the close relationship between seismic and logging information, a real-time prediction model of borehole stability is established using seismic, logging, and geological data to control borehole wall sloughing instability.

Source Rock Evaluation of Hydrocarbons in Deep-Water Offshore Areas Based on a BP Neural Network
Geofluids, 2023 Due to the lack of drilling data and poor quality of seismic data in deep-water offshore areas, conventional methods cannot effectively predict the total organic carbon (TOC) content. In this paper, the BP neural network method is used to predict the TOC

Bridge type classification: supervised learning on a modified NBI dataset
, 2017 A key phase in the bridge design process is the selection of the structural system. Due to budget and time constraints, engineers typically rely on engineering judgment and prior experience when selecting a structural system, often considering a limited ...

The Maximum Amplitude Weighted Integrated Energy Spectra: a New Gauge in Seismic Thin-Bed Interpretation [PDF]
, 2015 Some combinations of seismic attributes are superior in detecting thinbed thickness from 3D seismic data. However, their physical unit or meaning can be difficult to determine. Such attributes are considered as relative values.
