There are cases where discovered gas fields are not economically viable in the past due to the presence of large quantities of contaminants. These high contaminant gas fields are always associated with potentially high corrosion risk to the topside facilities and pipelines including an increase in project economics taking into consideration full separation technologies to be deployed to these fields. In fact, at the exploration-development stage, gas fields operators find it difficult to estimate the content of contaminants in their undrilled prospects for their better-informed decision-making strategy. As such, this paper discusses on 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. Using the similar technique of Petroleum System Modelling, this study will focus on identifying the source of contaminants, map the deep-seated fault which could be the conduit of migration and possible traps. Then, all these elements will be set as input parameters to numerical modeling to simulate the process of its’ generations, charging/migration as well as entrapment at those identified prospects.
