Agenda

Acoustic signature of deformation in the lab
Dr. Aletta (Nikoletta) Filippidou, Shell, The Netherlands

Typically, the strain response of the rock and the associated velocity changes is measured in pore depletion experiments. The velocity is determined by analyzing the first arrival of a transmitted ultrasonic wave. The relation between velocity changes and strain is generally well explored and understood. We propose a method for the monitoring of the deformation using the diffuse field, that is to say, focusing on the coda wave of the transmitted ultrasonic wave. Cross correlation analysis of the coda part returns higher order of information associated with inelastic changed in the medium. The applications are diverse and range from civil engineering, to seismology and reservoir monitoring.

Biography
Dr. Aletta (Nikoletta) Filippidou is a geologist, turned geophysicist, turned petrophysicist, turned geomechanicist; she basically abuses rocks, that’s it. She did her MSc jointy in the University of Athens and NTNU in Trondheim, and then a PhD in Geophysics at TUDelft. During her PhD she designed, acquired, processed and interpreted 3D seismic experiments of a Jurassic siliciclastic sequence in Northern France and a Miocene carbonate prograding reef in Mallorca using high-resolution high-frequency portable seismic sources. Her PhD thesis was ultimately on multi-scale transmission measurements, focusing on scattering and attenuation of seismic waves. She works for Shell since 2006, and focused on carbonate reservoirs, mostly in the Middle East for 10 years. The last two years she works for the Earthquake Study Team for NAM largely as a research coordinator and project manager, but also squeezing some time for own research within the Rock and Fluids Lab at Shell and TUDelft.

Rock Physics Integration: from Petrophysics to Simulation
Dr. Reza Saberi, CGG, The Netherlands

The science of rock physics creates a bridge between elastic properties (e.g. Vs/Vp, seismic, elastic moduli etc.) and reservoir (e.g. porosity, saturation, pressure etc.) and architecture (e.g. laminations, fractures etc.) properties. It also should allow for a reliable prediction and perturbation of seismic response with changes in reservoir conditions. An appropriate rock physics model should be consistent with the available well and core data, and surface and borehole seismic as well as production and reservoir engineering figures. This requires that rock physics act as an integrating tool between different disciplines. This talk review rock physics applications in different subsurface disciplines like Petrophysics, Geophysics, Geomechanics and Reservoir engineering.

Biography
Reza has been with CGG since 2011 and has more than 15 years of experience working in the oil and gas industry. He first started as a mining exploration engineer in Iran and then moved to the oil and gas industry as a geoscientist, geophysicist and rock physicist. He has been working with NIOC, Shell, Fugro-Robertson, Fugro-Jason and CGG in different roles in Iran, Norway and Netherlands. His most recent role is as Rock Physics Product Development Manager where he leads a team that develops different rock physics modules within the CGG GeoSoftware portfolio. He is also involved with different rock physics R&D projects in CGG and gives worldwide training on rock physics and its practical link with other subsurface disciplines. Reza holds a M.Sc. in Petroleum Geosciences, NTNU, Trondheim, Norway and a Ph.D. in Reservoir Geophysics and Rock Physics from the University of Bergen, Bergen, Norway.

As usual all have an opportunity to socialise with fellow petrophysical professionals over drinks and snacks.

Doors will open for registration and coffee at 3:30 pm and the talks will commence at 4:00 pm. The social hour will begin at 5:30pm at Cafe 2005 (Denneweg 7F, 2514 CB Den Haag).
