Geological disposal of nuclear or hazardous wastes

$Simul gas test frac 4$ $Sim gas tracer test frac 3$ $Sim gas tracer test frac 4$ $Sim gas tracer test frac 5$ Two-phase flow simulations of gas injection and gas tracer tests in a heterogeneous granite rock fracture (use of ATHOS).

Use of lab, log and seismic data for recognizing mechanical units in a geological formation foreseen as a potential storage of nuclear wastes, and for characterizing the spatial variability and trends of geomechanical and physical properties. Project carried out in collaboration with Geosubsight.
Illustrated bibliographical study and comparison of geostatistical approaches for aquifer characterization: integration of secondary information, estimation versus stochastic simulation, effects to mass transport, inverse problem, upscaling.
Fine scale simulation of single and two-phase (gas-water) tracer tests in heterogeneous granite fractures and history matching using a petroleum reservoir simulator (Athos). Project carried out in collaboration with Beicip-Franlab.
Two-phase (gas-water) flow simulations for potential nuclear waste repositories.
Assistance to conduct two-phase flow simulations of gas release in concrete storage canisters.
Advice in modeling two-phase flow laboratory experiments on cores for benchmark purposes.
