The next Dutch Petrophysical Society meeting will be held on Thursday 9th March 2023 with the topic “Geothermal – The SCAN Project”.

The meeting will be held at our usual venue KIVI in Den Haag (Prinsessengracht 23, 2514 AP Den Haag) with doors opening for pre-meeting coffees at 15:30, and the meeting commencing at 16:00.  Note that as for the previous meeting we will be holding the meeting in the ‘Molkamer’ on the first floor rather than our previous venue the Grote zaal.

You can register for the meeting below.

We have one talk “De-risking Dutch Geothermal Plays by Acquiring Subsurface Data – The SCAN Borehole Data-Acquisition Strategy” presented by Adriaan Janszen, Geoscientist, EBN BV. which will be followed by a discussion.

After the meeting there will be our usual social with drinks at a local cafe.

As always, thanks to the generosity of our sponsors, attendance is free for members of the DPS.

De-risking Dutch Geothermal Plays by Acquiring Subsurface Data – The SCAN Borehole Data-Acquisition Strategy.

Speaker: Adriaan Janszen, Geoscientist, EBN BV.

Abstract:
In 2017 EBN and TNO-AGE embarked on a geothermal exploration program (SCAN: ‘Seismische Campagne Aardwarmte Nederland’) to better define the geothermal prospectivity by reducing subsurface uncertainties through data acquisition. This program is government-funded through the Dutch Ministry of Economic Affairs and Climate and focused on acquiring regional 2D seismic data; reprocessing of existing 2D seismic data; and drilling of 7-10 data-acquisition boreholes (anticipated to be drilled between 2023 and 2025).

The SCAN boreholes will be drilled with the sole purpose of collecting subsurface data to de-risk relevant geothermal plays in areas in which previously limited data was available. The aim is for the boreholes to become key reference points representative of the Dutch subsurface domains and geothermal plays. Extensive acquisition of high-quality data is therefore essential.

A dedicated data-acquisition program was conceived to define what data should be acquired across different intervals. A well-thought-out data-acquisition strategy for the whole SCAN drilling campaign provides clarity during the design and tendering phase. It will be clear for internal and external parties what data to expect and ensures that data acquired in the SCAN wells can easily be compared and correlated. A generic data acquisition program that applies to all SCAN wells is also desirable for simplicity and allows for early-stage operational planning and cost-efficiency.

The resulting SCAN data-acquisition program is very comprehensive. For each borehole it consists of open-hole logging, coring, well testing, formation fluid sampling, formation-stress tests, temperature measurements, Vertical Seismic Profiles and mudlogging. All the resulting data will be made public, free of charge, on the SCAN website and the Dutch subsurface portal (NLOG) following drilling.

In this talk we will present the rationale and process of building the SCAN data-acquisition strategy and show examples of how this was applied to the first borehole that the project intends to drill later this year.
