DrChrisRochelle

I took a BSc in Chemistry with Geochemistry, Leicester University, 1986, and a PhD focused on fluid-rock reactions, Leeds University, 1990. I have over 25 years research experience of various aspects of the geochemistry of fluid-rock interactions, and in particular, designing, constructing, operating and interpreting experimental investigations. Much of this work has been related to the subsurface disposal/storage of waste materials He also has experience of supervising MSc, PhD and Post Doc researchers during their experimental work in the BGS Hydrothermal Laboratory. Relevant to the UKCCSRC is my extensive experience in the geochemical impacts of supercritical CO2 and CO2-rich fluids on host rocks, caprocks and borehole materials under deep basinal conditions. I also have extensive experience in: the role and properties of CO2 hydrate as a high pressure/low temperature storage phase within ocean sediments; the underground storage of radioactive waste (particularly those involving cement); and fluid-rock reactions within geothermal systems. I manage the BGS Hydrates and Ices Laboratory, and am a leading scientist in the BGS Hydrothermal Laboratory. These experimental facilities are used for the investigation of fluid-rock reactions over a wide range of temperatures and pressures.

 

RESEARCH ON CARBON DIOXIDE SEQUESTRATION

1992-1996: Participating scientist in the Joule 2-funded multinational project ‘The Underground Disposal of Carbon Dioxide’ (Joule 2 project No. CT92-0031). Main input to the project was on geochemistry and experimental studies of CO2-water-rock reactions.

1998-2000: Participating scientist in the EU Energie Programme SACS project, monitoring the underground CO2 storage project initiated at the Sleipner West gas field. Main input to the project was on geochemistry and experimental studies of CO2-water-rock reactions.

2001-2004: Led the work programme and proposal for, and participated as a scientist in, the European side of the International Weyburn project, monitoring the subsurface movement of CO2 within the Weyburn oilfield, Saskatchewan, Canada. Main input to the project was as initial project co-ordinator, and on geochemistry and experimental studies of CO2-water-rock reactions.

2001-2004: Participating scientist in the EC-funded NASCENT project, investigating natural CO2-rich occurrences in Europe as analogues of underground storage operations. Main input to the project was to consider some of the anecdotal information associated with natural CO2-rich systems.

2002-2003: Participating scientist in the EU Energie Programme SACS2 project. Main input to the project was on geochemistry and experimental studies of CO2-water-rock reactions.

2002-2006: Participating scientist in the EU Energie Programme CO2STORE project. Main input to the project was on geochemistry and experimental studies of CO2-water-rock reactions.

2004-2008: Participating scientist in the EC-funded CASTOR project, investigating several potential oil and gas fields for future CO2 storage operations. Main input to the project was on geochemistry and experimental studies of CO2-water-rock studies of possible reactions within the Casablanca (Spanish) and Snøhvit (Norwegian) oilfields.

2005-2009: Participating scientist in the EC network of Excellence CO2GeoNet, investigating covering a wide range of aspects relevant to the underground storage of CO2. Main input to the project is on geochemistry and experimental studies of CO2-water-rock reactions linked to host rocks (sub-project joint research area JRAP-7), caprocks (sub-project joint research area JRAP-1) and borehole infrastructure (sub-project joint research area JRAP-14).

2007-2012: Participating scientist in the EC-funded CO2ReMoVe project, monitoring several current CO2 storage operations. Main input to the project is on geochemistry and experimental studies of possible CO2-water-rock reactions of caprocks and borehole infrastructure above the CO2 store at Sleipner.

2012-present: Participating scientist in the EC-funded CO2CARE project, monitoring several current CO2 storage operations. Main input to the project is on geochemistry and experimental studies of CO2 dissolution into porewater within host formations.

2008-present: Project co-investigator leading BGS input and participating scientist in the NERC-funded CRIUS project, a collaborative university-BGS study of CO2-water-rock reactions in natural and experimental systems. Main input to the project is to manage overall BGS activities, and lead on experimental studies investigating the rate and magnitude of CO2-water-rock reactions.
