Reservoir quality prediction

Geocosm specializes in sandstone diagenetic modeling and reservoir quality risk assessment.

Our approach is scientifically rigorous, quantitative, reproducible, and testable. Our methods build on our expertise in sandstone diagenesis, petrophysics, basin modeling, computer simulation methods, and risk assessment.

Consortia

We work closely with industry and academia to develop and apply new technologies designed to reduce exploration and production related risk associated with sandstone reservoir characteristics. 

Technology

T>Map™ extends Touchstone by automating the simulation of sandstone reservoir properties using data from 3D basin models.  T>Map can use burial history data exported from any 3D basin modeling system. 

Touchstone

Our Touchstone software system incorporates facilities for analysis of controls on sandstone reservoir quality in analog samples and for forward modeling of sandstone diagenesis and petrophysical properties for areas away from well control.

Prism2D

Prism2D is our unparalleled system for simulation of sandstone diagenesis and is an important research tool for many Geocosm R&D activities.

COAN

COAN is an image analysis system for sandstones that was developed by Geocosm for quantitative analysis of the spatial geometry of grain coating materials, among other things.
