Multiscale Modeling of Gas Transport and Storage In Shale Resources

02 December, 2014
Who Should Attend
All geoscientists and engineers working in shale plays who wish to gain an understanding of gas transport and storage.
Objectives

The objective of the proposed work is to present a model for the fluid transport in nanopores of shale gas resources and to develop a framework for upscaling of the transport from nanopores into the micro- and macrofracture networks. The proposed work can lead to development of effective methods for gas production and CO2 storage in subsurface geological structures.

Course Content

Online Webinar - 2:00 p.m., CDT, 1 hour duration.

The gas transport in organic-rich shales involves different length-scales, from organic and inorganic pores to macro- and macrofractures. In order to upscale the fluid transport from nanoscale (flow through nanopores) to larger scales (to micro- and macrofractures), multicontinuum methodology is planned to be used. Governing equations describing the gas mass balance in multicontinuum models are the same as in a single-continuum model; however, they require special considerations for volume consistency and the mass-exchange terms. In this technique, unlike the conventional approaches, spatial coordinates of each continuum is not explicitly defined. Furthermore, the fluid transport and storage of each continuum are governed by different physics. Prior to applying the multicontinuum approach, well-founded techniques for simulating the fluid transport in nonoscale pores are required.

The nanoscale pores and capillaries bring new molecular level non-Darcian transport effects into the simulation. Therefore, conventional permeability concept, which is usually used to describe the transport of single-phase fluids in reservoir simulators, is no-longer valid.

Due to the recent achievements in microfabrication, considerable interests in the gas transport within miniaturized channels has emerged in other disciplines, such as Physics and material sciences. Several reduced-order Boltzmann equation methods, such as Grad's thirteen moment method are proposed to simulate the fluid transport with less computational times.

In the proposed work, the focus is on the upscaling of the transport phenomena using multicontinuum methodology by applying the recently-developed regularized Grad's thirteen moment simulation technique to the shale nanopores.

Structure of the E-Symposium

Each e-symposium consists of one-hour live e-symposium, along with material for one full day of independent study. The live portion will be followed by a full day of independent study (not a live event). The one-hour live e-symposium can be accessed from any computer anywhere in the world using a high-speed internet connection. After the event is over, you will receive via email information about accessing the asynchronous segment (not live) which consists of a recording of the event, your independent study materials, to be accessed and studied at any time. You will be able to email responses to the readings, along with your study question answers for CEU credit (if you sign up for the extended package).

Course materials will be available for download after the course closes.
