Top Seal analysis of a Failed Reservoir

The Norwegian Sea has a high potential of hydrocarbons. Many oil and gas fields are producing in this region. However, identifying prospects and positioning of production wells remain a major challenge. The Njord field is a Jurassic reservoir with several discoveries. Hence, this area is an excellent location for further exploration but recently, there have been a few wells drilled in this regime, which are declared as dry wells. Their data is yet to be released. The well 10–5, which has been drilled near the Njord field is dry although there are hydrocarbon shows in the neighboring wells. Obviously, it is of great interest to understand the reasons for the well being dry in an area of several petroleum shows. The evaluation includes the 3D seismic interpretation of the reservoir drilled by well 10–5. The dry well analysis is focusing on the seal potential of the layers above the reservoir based on 3D seismic attributes. The results indicate that the top seal shows two subtle fault pattern striking in E-W and NNE-SSW direction. The faults seem to be well connected and could be a reason for the failure of the well 10–5.
