GeoSim: feasibility for geophysical measuring through numerical simulations and controlled lab-scale testing
19:00 - 20:00 - Networking drinks
Abstract:
Adapting urban areas to the current demands of
the energy transition, as well as maintaining crucial infrastructures like
roads, bridges and quay walls, requires large investments for which understanding
of the subsurface is vital. In this study, an urban environment
was created in a scaled lab environment to test a multi-sensor geophysical
setup. The lab setup included a brick top layer, different soil types and
buried, leaking pipelines. Co-located electrical resistivity, seismic and
ground radar measurements were conducted while varying the hydrological
conditions as well as simulating a leakage from a pipeline. Where the ground radar data most clearly
delineated boundaries between different elements in the subsurface, the
electrical resistivity and refraction tomography provided material parameters,
though detection of small features like pipelines was not possible. The leakage
of the pipeline was clearly detected by monitoring the electrical resistivity
and, to a lesser extent through reflections of the leakage front in the ground
radar data. The acquired data from this study is a good starting point for
joint-inversion and data fusion, that is expected to yield more useful
information about the sub-surface than each of the individual sensors by
itself.

Speaker: Sanne Dekker (Shell)
Biography:
My name is Sanne Dekker, I am Dutch, I have a French husband and we have three children, all born in New Zealand. A long time ago I studied Applied Earth Sciences (at that time called “Mijnbouw”) in Delft, specializing in geophysics. For more than 20 years, I have worked as a geoscientist for Shell in the UK (London and Aberdeen), New Zealand, Oman and the Netherlands in Exploration, Development and more recently in CCS (Carbon Capture and Storage). Besides work, I enjoy doing sports, travelling, photography and playing the piano.
Upcoming December event:
Active and passive surface wave surveying in hard rock sites
Information:
Our February event will be organized with sponsoring from EAGE
Date: December 11th, 17:45-22:00
Venue: TU Delft Room F, CEG Faculty, Stevinweg 1, 2628CN, Delft
Registration via Google forms
Agenda:
17:45 - 18:00 - Entry to the event at room F in the CEG Faculty of TU Delft
18:00 - 18:10 - Welcome and introduction by Dr. Joeri Brackenhoff
18:10 - 18:40 - Technical talk by Prof. Valentina Socco (TU Delft; Politecnico di Torino) on:
Active and passive surface wave surveying in hard rock sites
18:40 - 19:00 - Q&A and Discussion
19:00 - 20:00 - Dinner at café X in Delft
Abstract:
Surface waves data can be retrieved by any seismic records acquired for active and passive exploration purposes with whatever receiver layout and exploiting both active sources and ambient noise.
In hard rock sites, which are typical in mineral exploration, the data quality can be critical, but the high velocities of the formations generate long wavelengths that allow large investigation depth to be reached.
With appropriate processing and inversion workflows that include the application of interferometry and surface wave tomography 2D and 3D S- and P-wave velocity models can be estimated.
A series of case studies using active sources, traffic induced noise and ambient noise will be shown and methodological aspects related to optimal receiver layout and processing strategies will be discussed.
