ESF supports excursion TU Bergakademie Freiberg

14 February 2019

On Sunday 25 November 2018 15 students from the TU Bergakademie Freiberg set out for Vienna
to visit OMV in Austria. Most of them are upcoming geophysicists in the Bachelor or Master
programme. The excursion had been planned by the EAGE Student Chapter Freiberg with and was made possible through the EAGE Student Fund. The
ESF is therefore happy to share the experiences of the students through this
report.

The main purpose of getting profound insights into seismic hydrocarbon
and geothermal exploration
by means of vibrator trucks. In addition, the excursion also provided students the chance to experience the dimensions of industry
surveys and furthermore, to establish personal contacts to OMV and ask specific questions
regarding our field of expertise. The following morning, on Monday 26^th November, our study
trip started in Strasshof. After an introduction and safety instructions we were led into
a workshop where defective geophones are repaired or simply recharged. As the geophones
do not transfer data in real time they have to be brought from the field to the workshop and
then manually read out. Each day quite a few terabytes of data are recorded so lots of memory
space is required.

A company presentation was given next and while enjoying some coffee and sweets
we found out more about the project: To ensure the security of gas supply in the future,
OMV performs seismic measurements north of Vienna as an extension of the survey area
already covered via 3D seismic earlier this year in Schönkirchen. Covering an area of 1,100 km²
it represents the largest seismic exploration in Austria so far.

Following the presentation, we moved out into the field by car to a geophone station
which consists of 12 or 24 in-line geophones that are permanently recording during working hours,
which are connected to a flash drive. In total, 720,000 geophones are placed around a perimeter
of several kilometres. Even at a distance of 4km they are able to detect seismic waves generated
by the fleet of vibro-trucks which we were allowed to visit next.

The most fascinating part of the field trip was witnessing the power such a vehicle can release
into the earth. Standing close by, it felt like an earthquake was rattling the ground beneath
our feet. Maximally four troops of three vibrators operate at least 400m apart with a
time delay of 20s. Using the slip-sweep technique almost 8km² can be measured daily.
The target of this measurement were geological formations containing gas or hydrothermal fluids,
which are located at a depth between 4 and 6 km. At the same time, Peak Particle Velocity
measurements ensure a destruction-free exploration without damaging buildings.
Generally, OMV values Health, Safety, Security and Environment (HSSE) and respects the choices
of landowners.

After lunch, we stopped by at the Recording Truck. Each vibrator transmits its exact position
to the truck, so the coordinators know where the exploration crew is located and can give
proper instructions. Each measurement point is registered in their system so the progress
can be monitored.

The trip was concluded by a visit of the Noise Monitoring Truck. On a fixed line several geophones
record the noise triggered for example by a storm. These geophones transmit the data
instantly to the truck. That way a measurement can be put to a stop at once if the background
noise exceeds a certain level.

In the end we left OMV after a very exciting day. All in all, we received a lot of new information,
could ask specific questions and got an impression what it means to work for OMV.
As a part of our course of study in Freiberg, we regularly participate in smaller scale
seismic surveys and it was impressive to experience a seismic survey at such an enormous
scale. It allowed us to get insights into the industry’s ways of handling such a large project.

Many thanks to OMV for this interesting excursion and to our sponsors: EAGE Student Fund,
Verein Freunde und Förderer der TU Bergakademie (VFF) and TU Freiberg’s Institute of Geophysics!

Field work and the ESF

Throughout the course of the year, the EAGE Student Fund supports a
number of field
work projects. The fund is looking for new initiatives where a limited donation directly
helps with the realisation of the excursion.

Second round qualifiers named in the LDC

7 February 2019

The Laurie Dake Challenge, previously known as the Field Challenge, is a fully integrated evaluation and
development task that challenges students to simulate a real industry activity. The challenge requires
cooperation between students and various disciplines, and is one of the main ESF supported activities
over the years.
In the first phase of the challenge, students will have to assess the prospectivity of an area
based on relatively sparse and limited data: it will be essential to understand the ‘backbone’
of the regional geology, to analyze the petroleum system(s) to evaluate its (their) probability of
being functional, and to describe the trapping mechanism that could lead to a promising prospect!
In the second phase, a relatively large amount of data and participants will need to ponder their
analysis by acknowledging the uncertainties which affect their work.
We celebrate the selection on the best ten entries. The remaining candidates will receive a
comprehensive dataset in the second phase of selection, which will allow teams to investigate
much more subtle relationships between the data in order to better characterize their reservoir.
The ten teams moving on the next stage of the competition are:
IFP School, France;
Dalhousie University, Canada;
Curtin University, Australia;
University Gadjah Mada( team 2), Indonesia;
Fluminense Federal University, Brazil;
Bandung Institute of Technology, Indonesia;
University of Stavanger, Norway;
Petroleum University of Technology (PUT), Iran;
Tomsk Polytechnic University, Russia;
and Mexican Institute of Petroleum, Mexico.
This contest would not be possible without the support of BP supporting the challenge with
the challenging dataset, as well as the Students Affairs Committee who worked hard to
prepare the 2019 Laurie Dake Challenge.

Student Lecture Tours – request for proposals

31 January 2019

Student Lecture Tours allow students to participate in a half-day course
taught by expert geoscientists. In 2018 the ESF supported tours in Europe
and Asia Pacific, resulting in lectures at 12 different universities.

Declaration of interest 2019

In order to gain support from the ESF, a student tour requires a declaration
of interest from several universities from the same region. This proposal
can come from both the university itself or a student chapter willing to
organise the lecture. The ESF accepts hosting applications throughout the
year. However, we recommend universities and chapters to make these
declarations well before the start of the academic year.

Learn more about becoming an SLT host.

A declaration of interest to host does not automatically mean the ESF will
award the request as it depends on the availability of the lecturer, topic
and interests of other universities in the same country or region.

If approved, the ESF support covers fee and travel costs of the
instructor. It cannot make contributions to catering, room rental or
equipment for the lecture.
