GESGB Evening Lecture: Decoding Salt-Controlled Systems at Seismic Scale

We’re delighted to be sponsoring and speaking at the GESGB London Evening Lecture Series on 18 September 2025.

Decoding Salt-Controlled Systems at Seismic Scale: From Halokinetic Sequences to Confined Turbidite Sand Fairways

Abstract

Interpreting salt-influenced basins remains challenging due to discontinuous horizons and complex salt geometries, often resulting in significant subsurface uncertainty.

This talk will present a multi-phase workflow designed to enhance correlation within salt minibasin settings and improve overall geological understanding. The approach includes:

Application of a global Relative Geological Time (RGT) modelling technique that transforms seismic data into a continuous stratigraphic framework, enabling detailed interpretation of halokinetic sequences, sediment stacking patterns, and depositional timing.
Integration of Machine Learning methods to support salt and fault extraction, as well as geological pattern classification using seismic amplitude and spectral magnitude attributes.

Case studies from the Gulf of Mexico and Brazil’s Santos Basin will demonstrate how combining interpretation with data-driven techniques can accelerate subsurface evaluation and offer a structured framework for characterizing salt-controlled depositional systems.
