Dictionary entry for Open data (edit)

Open datasets are explicitly and clearly licensed for use by anyone without permission from the rights holder. The purpose may or may not be restricted by the terms of the license — common exclusions are 'attribution' and 'non-commercial', though some people do not consider 'non-commercial' restricted data to be open sensu stricto. Public domain datasets are unrestricted in use or range, and have no license.

Introduction to the SEG Open Data Gateway

There is geophysical data you can download from the internet or request to be shipped to you. This wiki documents data that is readily available. Key parts of the data documentation are:

  • a descriptive overview of the data including types of data available
  • terms of use
  • how to obtain a copy of the data
  • how to obtain other support data
  • links to publications

2D Land Data

ALASKA 2D LAND LINE 31-81

2D land data from the National Petroleum reserve Alaska. This is a short line with small statics. There is ground roll and noise bursts, but there is also good signal. Data includes unprocessed prestack data, final stack, and images of previous stack. Scripts for processing with Seismic Unix are available. The data is provided by USGS.

ALASKA 2D LAND LINE 16-81

2D land data from the National Petroleum reserve Alaska. This line intersects 31-81 and the processing sequence is the same as used for 31-81. Seismic Unix scripts and a poster are available.

2D Marine Data

US EAST COAST DEEP WATER LINE 32

3D Land Data

TEAPOT DOME 3D SURVEY

A land 3D data set from Wyoming. Post stack data, well logs, production history, and GIS data can be downloaded from the internet after obtaining an FTP password. Unprocessed prestack data available by mail. This data is provided by RMOTC and the U.S. Department of Energy
