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)...

Pore-Scale Dissolution by CO2 Saturated Brine in a Multi-Mineral Carbonate at Reservoir Conditions: Impact of Physical and Chemical Heterogeneity

Al-Khulaifi, Y.; Imperial College London | Lin, Q.; Imperial College London | Blunt, M.J.; Imperial College London | Bijeljic, B.; Imperial College London

2019

The datasets contain 40 time-resolved segmented X-ray micro-tomographic images showing mineral dissolution of carbonate rock samples containing dolomite and calcite via CO2 acidified brine fluid flow at reservoir conditions. The tomographic images were acquired at a voxel-resolution of 5.2 µm...

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...

Dynamic X-ray micro-tomography Imaging of reaction of CO2-acidified brine with limestone at reservoir conditions

Hannah Menke, Imperial College London | Qatar Carbonates And Carbon Storage Research Centre

2018

This dataset contains 10 three dimensional x-ray tomographic images of CO2-acidified brine reacting with Ketton limestone at a voxel size of 3.8 microns. It includes the unreconstructed projections (.txrm), the reconstructed images (.txm), and the masked and cropped segmented images (.am and...

Bowland Shale dataset: field and sample photographs, sample descriptions, microphotographs, x-ray fluorescence, LECO elemental analysis, x-ray diffraction and RockEval pyrolysis from Hind Clough, MHD4 and Cominco S9

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...

FIB-SEM and X-ray micro-tomographic images of carbonate rock dissolution during reactive CO2-saturated brine injection under reservoir conditions

Kamaljit Singh, Imperial College London | Martin Blunt, Imperial College London | Qatar Carbonates And Carbon Storage Research Centre

2018

The datasets contain FIB-SEM and X-ray micro-tomographic images of a wettability-altered carbonate rock sample before and after dissolution with reactive CO2-saturated brine at reservoir pressure and temperature conditions. The data were acquired with the aim of investigating CO2 storage in...
