1. Challenge Description

The SEAM AI Parihaka Facies Challenge (the "Challenge") is a competition to advance the state of the art in machine interpretation of three-dimensional (3D) images of underground geologic structures created by the seismic reflection method. The challenge involves identification of different geologic regions called "facies" in seismic images made during exploration and development of petroleum reservoirs. Your contribution may help to improve the efficiency, accuracy, and environmental impact of exploration for oil and gas resources. Seismic images are also used in the exploration and management of underground water reservoirs and in the monitoring of waste-disposal sites, including reservoirs where carbon dioxide is injected underground to avoid its release into the atmosphere in the process of carbon capture and storage. This will be the first of a series of challenges related to machine learning for geophysical remote sensing of Earth's shallow crust.

This Challenge will be run in accordance to these Official Rules (the "Rules").

2. Sponsor

The Challenge is organized and sponsored by SEG Advanced Modeling Corporation (SEAM), Tulsa, OK, U.S.A., a wholly-owned, not-for-profit subsidiary of the Society of Exploration Geophysicists (SEG).

3. SEAM Admins

"SEAM Admins" are any companies or organizations authorized by SEAM to aid with the administration or execution of this Challenge, including but not limited to AIcrowd SA.

4. Challenge Start and End Dates

The Challenge page on the AIcrowd website ("AIcrowd Site") gives the start and end dates of the competition.

There will be 2 rounds of submissions in total. The first round serves as an introduction to the interpretation of 3D seismic images; Round 1 will be scored, but no cash prizes will be given as a result of the scores of Round 1. All cash prizes will be given in accordance with the results of round 2.

Round 1: You will be required to become familiar with 3D seismic images of underground structures and design initial machine-learning architectures to label facies in an image. A fully-labelled training image consisting of an 3D array of real numbers of dimension 1006 by 782 by 590 will be available for supervised training. Each pixel in the training image represents the strength of the echo returned to the surface from the spatial location in the Earth corresponding to the 3D array index of the pixel. Labels for the training image are stored in a 1006 by 782 by 590 array of integers from 1 to 6, corresponding, pixel by pixel, to a labeling of the training image by an expert geologist. The six labels represent the following geologic facies identified in the image are:

  • Basement/Other : Basement Rocks or Other: May contain volcanic deposits in places. Low signal-to-noise (S/N) echo amplitudes. Few internal reflectors.

  • Slope Mudstone A : Slope to Basin Floor Mudstones. High-amplitude echoes at upper and lower boundaries. Low-amplitude continuous/semi-continuous internal reflectors

  • Mass Transport Deposit : Mix of Chaotic Facies and Low Amplitude Parallel Reflectors

  • Slope Mudstone B : Slope to Basin Floor Mudstones and Sandstones. High-amplitude parallel reflectors. Low-continuity scour surfaces.

  • Slope Valley : High-Amplitude Incised Channels/Valleys. Relatively low relief.

  • Submarine Canyon System : Submarine Canyon. Erosional Base is U-shaped with high local relief. Mostly deformed slope mudstone filled with isolated sinuous sand-filled channels near the basal surface. Internal fill is low-amplitude mix of parallel inclined surfaces and chaotic disrupted reflectors.

An unlabeled portion of a test image, contiguous spatially with the training image, will be available to apply the trained machine-learning algorithm to. Submissions (consisting of proposed labels for the test image) will be accepted and scored by a simple metric. A final leaderboard, based on the scores for the test image in Round 1, will be posted at the end of the Challenge.

Deadline: See the Challenge page on the AIcrowd Site.

Round 2: You will be required to optimize labels. Ground-truth labels for the test image will be posted along with a more sophisticated set of metrics that take into account geologic knowledge in comparing submitted labels with ground truth. Additional unlabeled test images will be released, and multiple submissions will be accepted from competitors with each submission scored by the full set of metrics, which should allow competitors to refine their solutions. A final submission due before the end of Round 2 will determine the final leaderboard. By submitting your solution timely and adhering to these Rules ("Rules") you are automatically eligible for the Contribution Prize & Best Agent Prize. Good luck!

Deadline: See the Challenge page on the AIcrowd Site.

9. How Will Winners be Selected and Notified?

Entries will be ranked via an algorithm based on the scoring metrics devised for each round. Each entry will be assigned a score based upon the algorithm and such ranking will be displayed on the AIcrowd Site's Challenge specific leaderboard ("Leaderboard").

The entries of Round 1 and Round 2 will be scored separately. There will be a separate Leaderboard for each round, but all cash prizes will be awarded based upon the Round 2 Leaderboard.

Tied Entries.

If two or more participating Teams have the same score, a secondary algorithmic metric will be added to the scores. If, after adding the secondary algorithmic metric, all scores remain identical, prizes will be awarded to the Teams with tied scores and will be shared evenly among the Teams.

Potential winners will be contacted within 72 hours of each Deadline via the email associated with the AIcrowd.com account through which the entry was submitted. If a potential winner cannot be contacted, does not respond as directed, refuses the prize, or is found to be ineligible for any reason, such prize may be forfeited and awarded to an alternate winner. Only one alternate winner will be selected for each prize package, after which prizes will remain unawarded.

To the extent that there is any dispute as to the identity of the potential winner, the official account holder of the email address associated with the AIcrowd account through which the entry was first submitted will be deemed the official potential winner by SEAM.
