Clastic Reservoirs

 Environment of deposition + diagenesis Controls:

•Reservoir properties

 •Reservoir shape and connectivity

•Reservoir location

Understanding the reservoir leads to better predictions, and lowers exploration / development risk. 

Environment of deposition controls factors such as sorting and rounding, which in turn control reservoir properties

                       

Better sorting androunding generally results in higher porosity and permeability

 

Environment of deposition controls factors such as the shape and connectedness of reservoir rocks
