Other constraints

Either: (i) the dataset is made freely available, e.g. via the Internet, for a restricted category of use (e.g. educational use only); or (ii) the dataset has not been formally approved by BGS for access and use by external clients under licence, but its use may be permitted under alternative formal arrangements; or (iii) the dataset contains 3rd party data or information obtained by BGS under terms and conditions that must be consulted in order to determine the permitted usage of the dataset. Refer to the BGS staff member responsible for the creation of the dataset if further advice is required. He / she should be familiar with the composition of the dataset, particularly with regard to 3rd party IPR contained in it, and any resultant use restrictions. This staff member should revert to the IPR Section (ipr@bgs.ac.uk ) for advice, should the position not be clear.

Supplemental Information

EPSRC Project: EP/L012227/1 - The package (MATLAB) contains porosity profiles (Profiles_5mpm & Profiles_50mpm), spatially resolved propagators (Props_5mpm & Props_50mpm) and the scales for the different dimensions (Position (cm), PropScales_5mpm & PropScales_50mpm). Profiles are provided at 13 time-points, corresponding to 821 mL increments in acid flowed, starting at 0 mL. Propagators are provided at 12 time-points, corresponding to 821 mL increments in acid flowed, starting at 821 mL. Propagators are probability against dimensionless displacement (i.e. actual displacement divided by expected average displacement. This is obviously a function of the local (space and time) porosity. The local values of porosity have been taken from the profiles. The propagators have been normalised and non-dimensionalised in the following fashion: 1. Raw propagators are individually divided by their sum and subsequently the bin-size in the displacement dimension to produce a PDF (P(æ) x mm-1 Vs æ (mm)). 2. The propagator amplitudes are then multiplied by the expected mean displacement (EMD), where the displacement scale is divided by the EMD. EMD is calculated from the superficial velocity of flow at the two rates through a void the same size as the core and the observation time of 0.25 s. (P(æ) x æ0 Vs æ/ æ0) 3. The propagator amplitudes are divided by the spatially and temporally resolved values for porosity (ösr)– the porosity profiles. The transport scale is now multiplied by the same values of porosity to complete the non-dimensionalisation with respect to porosity and spatial position. ((P(æ) x æ0)/ ösrVs (æ x ösr)/ æ0)
