CO₂ Prediction in Offshore Sarawak Basin Through Petroleum System Modelling Approach

High contaminant gas fields always associated with potentially high corrosion risk to the topside facilities and pipelines including increase in project economics taking into consideration full separation technologies to be deployed to these fields. In fact, at exploration-development stage, gas fields’ operators find difficulties to estimate the content of contaminants in their undrilled prospects for their better-informed decision making strategy. As such, latest techniques of estimating the content of contaminants at undrilled prospects of gas assets to provide a better understanding to operators on their assets’ risks prior to any further development strategy

The basin model help improved the understanding on nature of CO2 (i.e. source, generation, migration etc.) and allowed for concentration and risk map to be developed to further identify the next low CO2 concentration risk exploration area. It was possible to define the uncertainty range on the CO2 concentration in all identified undrilled structures.
