Touchstone is a software system for analysis of controls on reservoir quality in analog sandstones and for forward modeling of sandstone diagenesis and petrophysical properties.
Touchstone is designed for:
- "Data mining" of analog sample sets to understand the controls on reservoir quality
- Quantitative prediction of porosity and permeability distributions in exploration or production areas with good well control and analog samples, and
- Quantitative risk analysis in frontier exploration areas
Touchstone comprises a database with querying and plotting facilities, a system for parameter optimization that can be used to calibrate the model to analog samples, and a system that integrates forward deterministic modeling with stochastic methods for prediction of reservoir quality distributions in undrilled areas.
