Fault Seal Analysis for Understanding Reservoir Compartmentalization & Performance during Production
Presented by: Surya Prakash Das, Geomodeler and Technical Presales Manager
Domain: Interpretation and Modeling
Fault seal analysis is one of many aspects studied in the exploration for hydrocarbons. It plays a vital role in understanding whether existing faults are sealed or leaking, and to what proportion. Fault seal helps in understanding volumetric uncertainty and plays a significant role in understanding reservoir performance during field production.
Fault seal can occur as a result of the juxtaposition of reservoir and non-reservoir rocks across faults. It is also related to how much displacement occurs across the faults, how much smearing a rock undergoes, and how much gouge is produced due to fault movement (both dependent on rock properties across the fault).
In this presentation and demo we will use these methods to calculate the sealing capabilities of a fault using SKUA-GOCAD technology. This will allow us to analyze to what extent a fault can be sealing in one part and non-sealing (or leaking) in another. We will find that depending on the throw and rock type distribution, a fault may have significantly varying sealing properties across it.
