DISCLAIMER: We are providing you with access to open source seismic and well log data. Our awesome DS&ML SIG committee members did their best to interpret seismic horizons and calibrate well logs to the seismic data. All data provided here represents are our best efforts. The data and any related materials contained therein are provided “as is,” without warranty of any kind, either express or implied, including, but not limited to, the implied warranties of merchantability, fitness for a particular purpose, non-interference, system integration, or non-infringement. The entire risk of use of the data shall be with the user. See the bottom of the page for accreditations.

Seismic Data

We are providing you with cloud-native seismic files in two different formats: OpenVDS+ and Real Simple Seismic (rss). Our team converted these from SEG-Y so you can have fast slice access for your machine learning pipeline! Please see our example notebooks on various ways to access the seismic data here and here. Cloud versions (for SageMaker) are here and here. Following seismic datasets are available. We may add more files (seismic attributes/features) during the competition.

    • Near, Mid, and Far Stacks in TWT

    • Full Stack with AGC (beware!)

    • Seismic velocity cube (rss only)


Wells

We ingested publicly available wells into a pandas DataFrame and we serialized it to our AWS S3 bucket in JSON format. The well names are blanked out and two of the wells are being kept as testing data. You can see examples of the well data ingestion and some basic visualizations here and here.

The cloud well data, after deserialization, unfolds into a MultiIndex pandas DataFrame. Well IDs and two-way-time values make up the MultiIndex. We also provide inline and crossline positions, true vertical depths (relative to sea level), and elastic logs.

Beware! There are missing portions of some of the logs, just like real life, so you either throw away useful data or augment it.

We encourage competitors to predict missing well logs with empirical or predictive models! Available well info:

    • P/S Velocities, and Density Curves

    • Deviations (accounted for in inline and crosslines)

    • Seismic Calibration (well ties, accounted for in two-way-time index)


Horizons

We interpreted a bunch of horizons and converted them to a pandas DataFrame. Serialized it to our AWS S3 bucket in JSON format, per horizon! Click here and here to see examples of getting the data. We interpreted the following surfaces (shallow to deep)

    • Water Bottom

    • Top Heywood

    • Top Johnson

    • Top Jamieson

    • Top Near Plover


The Plover formation is the main zone of interest and most well log data is available around this pick.
Well logs may not be available or reliable above the Top Jamieson surface.
A lot of useful information about the data and geology can be found here, some credits go to TerraNubis!

The Poseidon seismic and well data

is provided by Geoscience Australia

The Poseidon seismic and well data is provided by Geoscience Australia and used under the terms​ of the CC-BY 4.0 license. Seismic data was originally acquired from ConocoPhillips​

The seismic volumes were sourced from here:​

These spliced well logs have been provided free of charge by Occam Technology and are sampled at 0.5 m intervals. The data is as complete as it can be but there may be occasional gaps in the logs.​

The full resolution spliced logs can be purchased from Occam Technologies​
