2019

High-pressure multi anvil synchrotron data from ID06-LVP at the ESRF. Contains diffraction, radiography, MHz ultrasonic and calibration data from experiments performed to ~ 13 GPa on CaSiO3 perovskite and Ca[Si60Ti40]O3 perovskite samples.

Whole-rock XRD (X-ray diffraction) data of hydrothermal alteration from the island of Milos, Greece

Miles, Jo | Kemp, Simon | Wagner, Doris | Naden, Jonathan

2022

Summary of semi-quantitative whole-rock XRD analysis of hydrothermal alteration across the island of Milos, Greece. The samples were acquired during numerous field visits between 2010 and 2018 by the British Geological Survey and GW4+ Doctorial Training Partnership (NE/L002434/1). The data were...

University Of Leicester | British Geological Survey

2019

The data were produced by Joe Emmings, NERC-funded PhD student at the University of Leicester and British Geological Survey, between 2014 and 2017. Authors of these data: Joe Emmings a, b; Sarah Davies a; Christopher Vane b; Melanie Leng b, c; Vicky Moss-Hayes b; Michael Stephenson b a School...

X-ray Microtomography of Intermittency in Multiphase Flow at Steady State Using a Differential Imaging Method

Martin Blunt, Imperial College London | Ying Gao, Imperial College London | Qatar Carbonates And Carbon Storage Research Centre

2018

The images in this dataset are a sample of Bentheimer Sandstone from a micro-computed tomography (micro-CT) scan acquired with a voxel resolution of 6.00µm. We imaged the steady state flow of brine and decane in Bentheimer sandstone. We devised an experimental method based on differential...

Three-dimensional temporal imaging of X-ray CT imaging of dissolution-driven convection in glass beads

Dr Ronny Pini, Imperial College London | Rebecca Liyanage, Imperial College London | Qatar Carbonates And Carbon Storage Research Centre

2018

The images in this dataset show the mixing of two liquid solutions in a random bead pack as a function of time and in three-dimensions. The working fluids used in this study are solutions of methanol and ethylene-glycol (MEG, fluid 1) and brine (fluid 2). In particular, three mixtures of...

Relative Permeability and Flow Intermittency Measurements Using X-Ray Micro-tomography in a Complex Microporous Carbonate

Ying Gao, Imperial College London | Ali Q. Raeini, Imperial College London | Martin J. Blunt, Imperial College London | Branko Bijeljic, Imperial College London

2019

We imaged the steady-state flow of brine and decane at different fractional flows during dual injection in a micro-porous limestone using X-ray micro-tomography. We applied differential imaging on Estaillades carbonate to (a) distinguish micro-porous regions from macro-pores, and (b)...
