| Zusammenfassung |
| Hydraulic stimulations are the primary means of developing subsurface reservoirs regarding
the extent of fluid transport in them. The associated creation or conditioning of a system of
hydraulic conduits involves a range of hydraulic and mechanical processes but also chemical
reactions, such as dissolution and precipitation, may affect the stimulation result on time
scales as short as hours. In the light of the extent and complexity of these processes, the
steering potential for the operator of a stimulation critically depends on the ability to
integrate the maximum amount of site-specific information with profound process
understanding and a large spectrum of experience. We report on the development
of a virtual project laboratory for monitoring hydraulic stimulations within the
project SHynergie (http://www.ruhr-uni-bochum.de/shynergie/). The concept of the
laboratory envisioned product that constitutes a preparing and accompanying rather
than post-processing instrument ultimately accessible to persons responsible for
a project over a web-repository. The virtual laboratory consists of a data base, a
toolbox, and a model-building environment. Entries in the data base are of two
categories. On the one hand, selected mineral and rock properties are provided from the
literature. On the other hand, project-specific entries of any format can be made that are
assigned attributes regarding their use in a stimulation problem at hand. The toolbox is
interactive and allows the user to perform calculations of effective properties and
simulations of different types (e.g., wave propagation in a reservoir, hydraulic test).
The model component is also hybrid. The laboratory provides a library of models
reflecting a range of scenarios but also allows the user to develop a site-specific model
constituting the basis for simulations. The laboratory offers the option to use its
components following the typical workflow of a stimulation project. The toolbox
incorporates simulation instruments developed in the course of the SHynergie project
that account for the experimental and modeling results of the various sub-projects. |
