Geophysical Interpretations
The Geophysical Interpretation was primarily stored and shared on the OpenWorks platform.
OpenWorks is a project data management software developed by Haliburton and is extensively used for handling seismic data
The four sub-folders in the dataset give information about
- Fault polygons
- Faults
- Horizons
- Wells
Fault polygons
It is a set of lines, representing the hanging wall and footwall of the fault for each horizon.
Horizon
It is the imaginary interface between two different beds having geological dissimilarity like density, porosity, fluid content, etc
Fault
It is a crack in the Earth’s crust along which there has been an observable amount of displacement.
Folder: Fault Polygons
This folder gives information on the location of the fault based on the UTM (Universal Transverse Mercator) coordinate system & TWT (Two-way time).
- 2014_Volve_Hugin_Base.dat
- 2014_Volve_Hugin_Top.dat
The number of fault polygons defining the Hugin formation:
| Top Hugin | 78 Polygons |
| Base Hugin | 71 Polygons |
Folder: Faults
It contains Volve_Official_Faults.dat file which includes all official faults. A README.txt file provides guidelines to infer the data from Volve_Official_Faults.dat
Folder: Horizons
Two sub folders within main folder contains the horizon interpretation files.
- Horizons_DEPTH: Interpolated key horizons in depth.

Reports
We have two reports that summarize the studies carried to understand the field and also strategize the development.
- Discovery Report: It covers topics like seismic & structural Interpretation, Geological & Petrophysical evaluation of the field. Primary analysis like Drill stem test & Geochemistry, Resource & probability estimation to the future acquisition of new seismic data & drilling operation. It also contains structural maps, Isochore map & litho-stratigraphic correlation.
- Volve PUD: It is in Norwegian Language related to TECHNO-ECONOMICAL Analysis of the field. It covers topics like Geological evaluation, Reservoir modelling, Drilling & Production Technology, Operation & Maintenance, HSE (Health, Safety & Environment), and economic analysis.
Reservoir Modelling
Reservoir modeling & simulation is a necessary analysis to understand field performance & field development planning. The dataset has 2 folders:
Reservoir Eclipse Model
ECLIPSE (Simulation software) by Schlumberger provides Black oil modeling, Thermal modeling with a finite volume method.
Folder Contains Dynamic Fluid Simulation model (Model Volve 2010) including both results and input data.
Model contains drainage strategy and development from initial PDO*
Reservoir RMS Model
RMS offers facility for Reservoir characterization and modelling.
It has two reservoir Models:
- PDO for 2005
- Full Field Model for 2014
*Plan of Development & Operation
Seismic
Seismic surveys are a geophysical survey method in which the of reflected/refracted acoustic waves are used to map and understand the sub-surface. We collect data using crossed array methods where orthogonal grids are generated by sets of Inline (IL ) & Crossline (XL). We have four sub-folders:
OBC Seismic survey: Ocean Bottom Cable survey technique has a vertical series of Geophone or hydrophone deployed on the seafloor for recording & relaying seismic data.
- ST0202: 3D processed data for the OBC survey carried out in 2002
- ST10010: 3D processed data for the OBC survey carried out in 2010
- ST0202vsST10010_4D: Contains data from 4D processing of ST0202 and ST10010 (matched data).
- VSP: The recorded Check-shot and VSP profile data of wells . More VSP data is found in the folder Well logs\08.VSP_VELOCITY
A VSI tool is put in the borehole, with 4 receivers. The distance between the receivers is 15cm. A source is located right above the VSI receivers (in the center). The average TWT of the first arrivals in the 4 receivers is taken. The boat and the VSI tool move after every shot.
Each seismic survey processed data folder has the following sub-folders:
- PreMig_data: Contains shot gathers and offset data of the survey.
- Prestack_data: Common Image Point (CIP) gathers for PZ and PS gathers, in depth and in PP time.
- Raw_data: NAV merged raw data from the OBC survey
- Other_data: Source Signature and Tides data data
- Stacks: Contains raw and final stacks of the processing of seismic survey
- Documentation: Final field operation report for marine seismic reflection survey (2002)
- Velocities : Contains velocity models used to migrate the seismic survey
NAV merged data combines seismic data with various geometry formats and provides SEGY data that has trace headers populated with correct source and receiver X,Y positions.
We are looking for students, researchers, professionals who can help us develop content based on the seismic data. Please contact us if you have ideas!

Hello,
from where can i download these data to use it in tutorial posted into my youtube channel
Please refer to this article for the procedure to access the dataset: How to Access the Volve Dataset?
Would you be able to advise what are the LFP (Lithological Fluid Prediction) data? I see plenty of channels there that kind of repeated with Composite and LWD/EWL sets, but I struggle to understand where is this data coming from. Is LFP some kind of interpretation of seismic data processed by Geolog software?
Thanks!
Yes, LFP is an interpreted log.
Thank you Ankit! Would you maybe be able to advise where to look fot some more detailed explanation of channels meaning? I can only find a unit in ASCI files, but cannot always figure out subtle differences between channels.
Are you talking about the well logs? Can you please provide more information about your query.
Yes, I am asking about data available in ASCII well log files. They come in categories (as per folders) MUD_LOG, LWD_EWL, COMPOSITE, etc. When you open a file for a specific well you see multiple channels with no description. Some of them are obvious to me (e.g. GR, CN, CAL) but some of them are less obvious. For example in COMPOSITE log for well 15/9-19 A you have multiple radioactive-related logging channels (judging by unit CPS): LSN, SSD, HRD1, etc. Similar situation with resistivity, for example. I would like to understand what do those channels mean. I believe this kind of information would normally be passed to the operator by logging company as a part of data delivery package.
On a note — I am using JSON format of those logs as I was not able to open original LTI files. Possibly you can advise any software that can deal with LTI?
I have not been able to identify all the channels. Maybe you could do a quick google search or look for the information available in the header of those file.
Hello, do you have any idea of what tools they were use? Tools about well logs, like LWD, SP, Gamma Ray. Been looking, but didn´t find that kind of information, thanks!
There is a lot of information available about the tools used in the End of Well reports. I was planning to do an article and would really appreciate some help.
Hello Ankit! Wonderful thing you’re doing!
My question is: does the volve database have any data about multilateral wells? And if so, how can I navigate through the data quickly to find what I am looking for?
Thank you! There are no multi-lateral wells in the Volve Dataset.
Hi
Just wondering, if any one figured out what is the scale of core images provided in the dataset.
A number of thin micro images of cores are provided for two wells. But no real scale if provided, thus rendering the data useless for research purposes. Doe any one have any knowledge about how to figure it out
I was just wondering whether seismic processing reports have been released as part of the data package? I don’t seem to be able to find them. Thank you very much in advance.
I am not very conservant about the seismic aspect. Can you share what kind of reports are you expecting the database?
Hello, where is the LAS file for the 19 wells under the Hordaland Group Formation, do you know where it is, I can’t find the file location for it.

I do not understand the question. Can you please elaborate? Most well log data is available in the Well Logs section of the dataset.
https://discovervolve.com/2020/09/26/navigating-well-log-formats-in-the-volve-oilfield-data-with-the-welly-library/
Hi there! I was just wondering if the volve data set contains any caliper logs or any other types of logs to measure the borehole diameter with depth.
Thanks in advance!
There are Caliper logs available in the dataset. You’ll find them the the Well Logs/Petrophysical Interpretation section.
Or any formation imaging logs that help us identify the in situ stress directions.
Hi, There are formation image logs available for two well: F-12 and F-14.
