Controls on Sandstone Diagenesis and Reservoir Quality

This course is designed for exploration and production geologists, geophysicists, and managers who are concerned about assessment of reservoir quality in sandstones away from well control and wish to learn more about the state-of-the-art in predictive modeling approaches.

We provide participants with an overview of the primary textural, compositional, and diagenetic influences on porosity and permeability of reservoir sandstones from a wide range of geologic settings. We also review recently developed approaches for predicting sandstone reservoir quality away from well control using diagenetic models and how these models can be used to evaluate reservoir quality variability and uncertainty prior to drilling.

This one to two day course covers the following topics:

  • Compaction in both lithic-rich and lithic-poor sandstones
  • Quartz cementation
  • Carbonate and clay cements
  • Role of textural characteristics such as grain size and sorting
  • The impact of grain coatings such as detrital clay, chlorite, siderite, and microcrystalline quartz
  • Controls on and significance of secondary (dissolution) porosity

Available for all companies and institutions.

Touchstone Fundamentals

This two day course assumes no Touchstone modeling experience and is designed for prospective Touchstone modelers, individuals who apply Touchstone results, basin modelers who provide input data, or anyone else who desires to know more about the system and the results it produces.  The course consists of paired lectures and hands-on exercises.

Topics:

  • Project design and input data
  • Compaction and replacement
  • Quartz cementation and paragenesis

Quartz Cementation in Cataclastic Zones Workshop

This lecture and exercise provide an overview of the optional module in Touchstone for defining the timing of cataclastic deformation together with its effect on the grain size distribution.  This information, in turn, may have a dramatic impact on the results from the permeability and quartz cementation models.

Open to RQC members and students and academic staff from universities that have been awarded software grants from Geocosm.

 

Plagioclase Albitization Workshop

This lecture and exercise provide an overview of the Perez and Boles (2005) model for the albitization of calcic plagioclase and its implementation as a optional module in Touchstone.

Open to RQC members and students and academic staff from universities that have been awarded software grants from Geocosm.
