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)...

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...

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...

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...

Silica rheology data

Simon Hunt, University College London

2018

Synchrotron X-radiography (images) and diffraction data collected to measure rheology of Quartz coesite and stishovite.

Physical and visual effects of ocean acidification on cold-water coral (<em>Lophelia pertusa</em>) skeleton samples from the Southern California Bight, USA (2010-2015) and the Mingulay Reef Complex, UK (2012).

Hennige, Sebastian | Wolfram, Uwe | Wickes, Leslie | Murray, Fiona | Schofield, Sebastian | Kamenos, Nicholas A | Roberts, John Murray | Groetsch, Alexander | Spiesz, Ewa | Aubin-Tam, Marie-Eve | Etnoyer, Peter

2020

This dataset contains visual and physical analyses of the impacts of ocean acidification on the skeletons of the cold-water coral Lophelia pertusa. Visual analysis includes synchrotron images from the Diamond Light Source and electron back scatter diffraction images on polished coral skeletons....

Sediment organic material by loss on ignition for stations from the Western Barents Sea for summer 2017 and 2018

Solan, Martin | Godbold, Jasmin | Grange, Laura | Ward, Ellie Rose | Wood, Christina | Reed, Adam

2020

Sediment organic material content obtained from replicate 0.1m2 USNL (Unites States Naval Laboratory) box cores are determined by loss on ignition. Samples were collected on cruises JR16006 and JR17007. Funding was provided by 'The Changing Arctic Ocean Seafloor (ChAOS) - how changing sea ice...
