Porosity and permeability determine to a large extent the success of gas production. As the most high-productivity fields in the Netherlands are largely explored and produced we are left with tighter and less prolific areas. Different types of cements are generally not equally distributed in sandstone reservoirs.
Cementational porosity/permeability loss can have a strong influence on the total reservoir quality reduction in some intervals or locations. This study is ultimately aimed at increasing the ability to predict the quality of the sandstone reservoirs at unexplored locations by understanding the cementation within the Upper Rotliegend reservoirs of the Dutch subsurface. The prediction of the mineralogy at a location with more certainty may also allow a better approach to well design and production/injection procedures.
