PESA QLD: July Technical Evening – Constrained by Geology: Reducing Sub-Seismic Uncertainty with Depositional Analogues and Synthetic Data

Thursday, 30 July @ 5:00 pm - 7:30 pm (Australia/Brisbane time)
$15.00 – $45.00

Guest Speaker(s): Dr Boyan Vakarelov

Boyan Vakarelov is the founder of SEDBASE, a cloud-based platform that helps geoscientists manage subsurface uncertainty using depositional analogues, dimensional datasets, and integrated decision-support tools.

An internationally recognised expert in shallow-marine sedimentology and sequence stratigraphy, Boyan brings more than 20 years of applied research and industry-focused experience. His work focuses on linking depositional process understanding to improved subsurface prediction in data-limited settings across various hierarchical scales.

Boyan uniquely combines deep geological domain expertise with hands-on software, database, and web product development experience, bridging the gap between traditional sedimentology and building digital-based solutions. Boyan previously held research and teaching positions at the University of Adelaide. He holds a PhD from the University of Texas at Dallas and a BSc from the University of Toronto.

PESA QLD July Technical Evening

Constrained by Geology: Reducing Sub-Seismic Uncertainty with Depositional Analogues and Synthetic Data

Presented by: Dr. Boyan Vakarelov (Founder, SEDBASE)

Abstract:
Many critical subsurface decisions depend on predicting fluid flow through stratigraphic architectures that occur below typical seismic resolution or in areas with sparse well control. This sub-seismic uncertainty can be meaningfully reduced through following a geology-first approach, where depositional variability is constrained by process understanding and calibrated against natural analogues. Such an approach should embrace multiple geologically valid solutions and focus on the architectural scale most relevant to the decision at hand.
This presentation draws on insights from an extensive depositional analogue database compiled over the past two decades, highlighting how process regime and system type control the architecture of shallow marine and fluvial successions. We will then demonstrate how forward stratigraphic and object-based modeling workflows can generate geologically realistic scenarios in data-limited settings. These models not only improve uncertainty quantification and ultimately flow prediction, but also provide physics-informed synthetic datasets for training AI neural network models.
