Workshop 2

Workshop 2 – 2 November

Quantification of uncertainty in offshore ground models

Workshop Description

Quantifying uncertainty in ground models is essential because designs are often based on limited, variable geotechnical and geophysical data within laterally and vertically complex geology, where errors can have safety and cost consequences.
Explicitly representing uncertainty allows risk-based design, helping engineers
understand the likelihood and impact of adverse ground conditions rather than
relying on overly conservative assumptions. This leads to safer, more economical
foundations, better-informed site investigation strategies, and improved decision-making. This workshop will focus on identifying key sources of uncertainty in offshore ground models, methods for quantifying them, and a panel session on what levels of uncertainty are acceptable.

Objectives
Identify and categorize sources of uncertainty in offshore energy projects
Target audience
– Project teams – Geoscientists, Engineers, Project Managers
– Developers
– Asset owners
Key Topics
– Types of Uncertainty
– What level of uncertainty is acceptable

SLB

Dariusz obtained his MSc at Wroclaw University in Poland in 2002.

After his PhD (2007) in geology, gas isotope geochemistry and microbiology at the Indiana University, Bloomington, he has worked in Subsurface Technology at ConocoPhillips for three years followed by one year of consulting (Dariusz BioGeoChem) working on petroleum systems and subsurface biomethane stimulation.

In 2012 he has joined SLB and since then has been developing interpretation workflowsand answer products for surface formation evaluation (mud gas and cuttings logging). Since couple of years his works involves H2 and helium logging and exploration, for which the global activity is rapidly growing.

This topic also brings ideas of stimulated natural H2 in the subsurface, which brings together geological and fluid geochemistry knowledge to a new level of collaboration among academic and industrial communities.

Dariusz is very active within the geochemistry community, with multiple peer-reviewed papers and chapters, numerous conference-related activities, journal editorships, and intellectual property publications.
