SEAM Open Data

SEAM Open Data draws from the work of the SEAM Phase I and Time Lapse Pilot projects to make small proprietary data sets available free of charge to the public to advance research and innovation in geophysics.

SEAM Open Data is hosted using the Google Drive online service.

Can modern numerical methods simulate changes in the geometry and physical properties of a reservoir over time — the changes in the rocks, pore fluids, and pressures that accompany reservoir flow and production — well enough to explain and predict the subtle effects that are seen in time-lapse geophysical surveys of real oil fields?

SEAM Phase I Interpretation Challenge

Using the SEAM Phase I Model the Interpretation Challenge offers an excellent opportunity to learn interpretation skills, evaluate interpretation software on a small well known dataset and also identifying the uncertainty in determining important steps in risking a well being drilled.

Phase I 2D Data Sets

Elastic Earth Model Subset - 2D

Five earth models were generated in SEAM Phase I to simulate a realistic earth model of a salt canopy region of the Gulf of Mexico complete with fine-scale stratigraphy that includes oil and gas reservoirs. The model represents a 35 km EW x 40 km NS area and 15 km deep. The grid interval for the Elastic Earth model is 20 m x 20 m x 10 m (x,y,z).  All model properties are derived from fundamental rock properties including v-shale (volume of shale) and porosities for sand and shale that follow typical compaction gradients below water bottom. Hence, properties have subtle contrasts at macro-layer boundaries, especially in the shallow section, generating very realistic synthetic data.

The Elastic Earth Model distribution is the model used for simulation of the SEAM Phase I RPSEA elastic data set. For the simulations, the minimum S-wave velocity was set at 600 m/s by compressing all S-wave velocities in the originally designed model having velocities between 100 and 800 m/s into a range between 600 and 800 m/s. This distribution has 3 binary files, one each for the density, P-wave velocity and the S-wave velocity. A README is also included.

This model 2D sub-set is 35KM in the east-west direction at North 23900 m.
It is designed to be used with data sets:

Elastic 2DEW Classic

download now

This 2D East-West dataset contains all the traces and all the shots along North location 23900.  The data is split-spread and contains receivers from East 0 to East 22500 m at an interval of 25 m making a total of 901 receivers per shot.  There are 151 shots from East 3700 m to East 18700 m at an interval of 100 m.  Traces are pressure recorded 15 m below the non-absorbing sea surface. Each trace contains 2001 samples at 8ms interval for a total length of 16 seconds.

Elastic VSP – 2D Walk-Away

download now

This 2D walk-away VSP for well number 1 contains 4-component data.  Well 1 is located at North 23900 m and East 10075 m.  There are 151 EW shots along North 23900 m into 467 down hole 4 component receivers from a depth of 1000 – 7990 meters incrementing by 15 m.  The 151 shots are from East 3700 m to East 18700 m at an interval of 100 m.  In effect, the shots walk-away to both the West and East directions from the well.  The shots are initiated 15 m below the non-absorbing sea surface. 4 traces per level are pressure and 3-components of particle acceleration.  Each trace contains 2001 samples at 8ms interval for a total length of 16 seconds.
