Machine learning can support interpretation and simulation, but outputs require geoscience and engineering review.
Seismic volumes and well logs provide different views of subsurface structure. A 2024 study evaluates a hybrid CNN/Transformer for 3D seismic fault detection. Reservoir simulators model fluid flow; surrogate models approximate selected outputs for particular histories or parameters. Porosity and permeability are distinct rock properties. Geosteering uses measurements while drilling to make trajectory decisions, and 4D seismic compares repeat surveys over time. A laboratory-scale early-kick study applies supervised learning to flow and downhole measurements, while DataDRILL provides separate datasets for formation-pressure prediction and kick detection. These studies do not establish field-wide performance or guarantee safe drilling.
A CNN can classify faults in 3D seismic volumes in a research study.
Porosity describes pore-space fraction, while permeability describes a rock’s ability to transmit fluids.
A surrogate model can approximate selected reservoir-simulation outputs to reduce repeated computation in a studied case.
Geosteering updates a well path as new measurements and interpretations become available.
Validate subsurface models against wells, core measurements and independent survey areas. Report the basin, data resolution and uncertainty. Applying methods to carbon storage or geothermal projects requires separate evidence and calibration; an oil-and-gas benchmark does not establish performance there.

A Exploration AI interpreta imagens de pesquisas sísmicas e medições de registros de poços, que revelam a estrutura e as propriedades da rocha subterrânea.
The cited ResACEUnet paper evaluates a hybrid CNN/Transformer U-Net for 3D seismic fault detection; this scoped question describes that study, not fieldwide prevalence.
The study builds a supervised model using laboratory drilling data, combining downhole monitoring and flow-related measurements such as mud flow-out rate, conductivity, density and pressure; it does not establish field-wide safety performance.
The cited paper presents an ANN surrogate for a specific oil-reservoir simulation case; it does not establish a general scale such as thousands of scenarios across all fields.
DataDRILL introduces two datasets for formation-pressure prediction and kick detection, describing 28 drilling variables and more than 2,000 samples for technical validation.
