To reduce Green House Gas (GHG) emission will lead to more renewable energy and less fossil fuels consumption and consecutively production. In parallel the Carbon Capture Usage and Storage (CCUS) business is set to develop rapidly. However, safely injecting massive amount of CO2 into the underground (saline aquifer or depleted fields) is more challenging than producing hydrocarbons from a known reservoir. Site integrity monitoring and early CO2 leak detection are amongst the biggest challenges, beside site characterization. Capabilities to address them will be requested by the regulators and by the public for acceptance. 

Surveillance will require technologies like microseismic monitoring, either from surface or from borehole. Each CCUS project will need a pre-injection feasibility study to design the best sensor network architecture and set performances expectancies. Acquisition will be performed from surface, from borehole or both over long periods of time. Data harvesting and processing will be performed permanently in an automated workflow. To achieve these objectives, the site operators need to demonstrate their expertise and the technologies capabilities through a permanent benchmark based on a common modelling and simulating platform. Today microseismic monitoring, largely used for various applications presents unsolved challenges for large scale projects (like CCUS). Using a common and public geological model to generate synthetic data is a solution for the technology to get more credibility. 

We discuss how each contractor could test internally its own performances versus public results. Academia and other entities could use also this common platform to develop new methods or solutions. Present limitations could be mitigated, after analyzing and quantifying the gaps like localization uncertainties. The model will be complex due to the nature of CO2 injection where multiple parameters are deeply involved. It is probable that such a model will evolve in time. The SEAM (SEG Advanced Modelling) consortium is the tool of choice to gather all these opportunities. A public consortium of expert entities (academia, site operators, technology providers) generating a common model and synthetic data sets will give the credibility and openness necessary to progress in scientific knowledge. It will also provide the necessary transparency to get regulatory approval and public acceptance.  

 

 

Speaker Biography: Michel Verliac, TotalEnergies Geophysics Innovation Group
M.Verliac is Borehole Geophysics Senior Specialist within the TotalEnergies Geophysics Innovation group at the Pau technical headquarters (France). He joined Total (now TotalEnergies) late 2013. Since that date, he has been involved in operations support to the group affiliates around the world as being involved in technologies development. This covers mainly borehole seismic imaging as microseismic monitoring, both conventional and by optical sensing. More recently, he focused deeper on technology development for Carbon Capture and Storage monitoring solutions and applications. 

Before joining TotalEnergies, M.Verliac worked for more than 20 years in Schlumberger, firstly in the field as borehole geophysicist in West Africa and Latin America (from 1991 till 2002) before joining the Wireline Headquarter team in Paris. He acted as worldwide Borehole Geophysics Domain Champion from 2002 till 2007 before joining Schlumberger Carbon Services and Schlumberger Information Services in 2010. 

Michel hold two masters in Geophysics and Geochemistry for the Strasbourg Earth Physics Institute and one Specialization Master in Geophysics from the IFP School in Paris. 

He is SEG, AAPG and EAGE member. He is member of the SEG Research Committee, SEG Membership Committee and past chairman of the SEG CO2 subcommittee. 

Speaker Biography: Joel Le Clavez, Schlumberger

Joël Le Calvez graduated with a B. Sc. degree in Physics from the University of Nice. He completed a M. Sc. degree in Geosciences from the University of Nice-Sophia Antipolis prior to graduating from the University of Paris VI with a pre-doctoral degree in Geodynamics.  He subsequently earned a Ph. D. in Geology at the University of Texas at Austin where he specialized in structural geology, salt tectonics and physical modeling. He worked for the Bureau of Economic Geology at the Applied Geodynamics Laboratory, where he developed an interest in graben and fault linkage, extensional tectonics, passive margins and modeling. 

Since 2001, Joel has been working for Schlumberger mainly on the topics of brown field and unconventional. During the first year, he worked on seismic interpretation to help with the selection of drilling sites offshore Angola. Subsequently he focused on log interpretation in the Wilcox formation and brown field in West Texas. At the start of the ‘unconventional era’, Joel has been offered the opportunity as a geologist to work in the field of induced microseismicity and hydraulic fracturing. He spent the next decade actively participating in the understanding of the geology and geophysics of unconventional fields both in the US and internationally (e.g., Argentina, Australia, China, Europe, Middle East). Ultimately, he helped with the development of the field acquisition, processing, visualization and interpretation tools and platforms which Schlumberger currently uses in the monitoring of induced microseismicity coupled with hydraulic fracture treatment and other applications (e.g., CO2 sequestration, geothermal injection, etc.) utilizing downhole, shallow wellbores and surface arrays. In 2008, he moved to the heart of the US Land unconventional boom, leading a team of geologists, geophysicists and engineers in Dallas. In 2011, he moved to Houston and as the North America Microseismic Domain Expert for Schlumberger managed the processing groups in US Land while providing training and support to the international processing groups.

In 2014, Joel was named Global Head for the Geophysics Domain of the then Data and Consulting Services, now Analysis and Interpretation arm of Schlumberger. While continuing his operational obligations, he works jointly with the acquisition segments to decide the direction of Schlumberger’s geophysics in terms of acquisition, processing and interpretation.

In May 2020, Joel added the North America Well Integrity and Production Logging businesses to his portfolio while being involved with the development of the fiber optic business as it benefits not only the geophysical world but the well integrity and production logging domains among many.

In January 2022, Joel took the position of Reservoir Performance Optical Fiber program manager before adding the Production Services portfolio later in the year. He currently coordinates the effort associated to sustaining, cable and interrogator manufacturing, research and development directions as well as business-focused answer products for all domains relying on fiber optic as a mean to acquire data.
