Abstract:
One idea that will be taken away from this lecture is the observation that fluid molecules in nanopores influence recoveries from resource shale.
It is now well-documented that the resource shales consist of pores with small volumes contributing to the storage of hydrocarbon fluids. These volumes are not much larger than the fluid molecules they store. Physical chemistry of fluids under confinement in such a small space is different and could lead to various equilibrium thermodynamic states under subsurface conditions; consequently, phases could change and critical properties shift unpredictably.
This presentation will discuss PVT behavior of confined hydrocarbon fluids using atomistic modeling and molecular simulations and will be compared to the classical fluid. The behavior is different mainly due to pore-wall dominated inter-molecular forces. The molecular forces also play a significant role on the fluid transport and could lead to potential non-Darcian flow effects during the production. The molecular transport effects on flow will be introduced to the audience using meso-scale lattice Boltzmann simulation of gas dynamics in nano-capllaries and analyzing the pressure pulse decay data for the permeability of core plugs under effective stress.
The presentation will conclude with a demonstration on the impact of fluid behavior under confinement on shale hydrocarbon in-place calculations and, using reservoir flow simulations, on the reserves.
Biography:
Yucel Akkutlu is associate professor of petroleum engineering at Texas A&M University. He has been participating in industry-led research on development of new laboratory techniques and protocols in quantifying fluid storage and transport processes in organic-rich shales coupled with geomechanics. His current research is on fluid thermodynamics and capillarity in nanoporous materials, and on the scaling-up and simulation of transport processes in multi-scale pore structures. Akkutlu is a chemical engineer and holds PhD in petroleum engineering from the University of Southern California. Previously he has worked for the University of Oklahoma. He is executive editor of the SPE Journal.
