Rock mechanics data for 31/5-7 Eos well core

This dataset contains the results of a rock mechanical testing program performed by NGI for Equinor on sandstone and shale from CCS exploration well 31/5-7 (Eos) in EL 001. Samples are from Cook sandstone (2680.25 -2680.5 m), Johansen 4 sandstone (2761.00 - 2761.25 m), Johansen 3 sandstone (2725 - 2725.25 m), and Intra-Drake shale (2592.00 – 2595.18 m) formations.

For each of the 3 sandstones, data from 3 triaxial tests, 1 hydrostatic test, 1 uniaxial stress test, and 3 Brazilian tests are presented. These tests allowed for the measurement of key mechanical properties of the sandstone.

For the shale, data from 4 permeability tests (2 on vertical plugs and 2 on horizontal plugs), 5 undrained triaxial tests (3 on vertical plugs and 2 on horizontal plugs), and Brazilian tests on vertical and horizontal plugs are presented.

The datasets are provided in the form of excel spreadsheets accompanied by PDF figures illustrating the data and containing photos of the samples.
