Outline, Message, Discussion<br />
1. Case for Areal Monitoring; reason, value, scale<br />
2. Shell – Large Portfolio & Wide application of Areal Reservoir Surveillance<br />
3. Shell – Using advanced methods to monitor complex difficult fields<br />
a) PRM (Seafloor and Land) – Holy Grail!?<br />

1. The case for Areal Surveillance<br />
Areal Surveillance because our reservoirs are<br />
heterogeneous and will produce different than expected.<br />

4. Shell 4D Coverage & Penetration<br />
4D coverage<br />
To date more than 80 fields<br />
have had a 4D monitor<br />
Large 4D program in 2012<br />
90% offshore waterflooded fields<br />
covered by end 2012.<br />
100% by 2014.<br />
4D penetration (Brown + Green Fields)<br />
Screened all Shell fields globally for:<br />
�� Value and potential business impact<br />
�� Technical Feasibility<br />
�� Do-ability of 4D survey<br />
This defined the “Applicable Base”<br />
Applicable Base ~25% resource base<br />
Currently 68% applicable base covered<br />
Mainly Land<br />
If currently planned surveys are<br />
completed 90% covered by 2015<br />

5. Improved Integration; 4D Automatic History Matching<br />
Challenge<br />
� Obtain in less time more accurate reservoir models which are consistent<br />
with available production and 4D seismic data<br />
Solution<br />
� Novel methodologies for (semi-)automated “history matching“ of reservoir<br />
models have been developed, demonstrated, and deployed to Assets<br />
Business Impact<br />
� History match performed in less time (5 months<br />
reduction achieved)<br />
� History match led to more realistic models and<br />
improved reservoir understanding<br />
� Technology first � quantitative use of 4D seismic<br />
data<br />
� Workflows adopted in Assets can be easily<br />
replicated<br />
� Successfully handed over to staff in Assets<br />
� Plan for global deployment<br />

Thank You
Why we need Areal Surveillance & Smart Fields?<br />
Stacked reservoirs/ oil rims<br />
Toxic HC developments<br />
EOR<br />
Increased complexity Improve recovery & performance Improve integration<br />
Reduced flaring policy<br />
More partners/ stakeholders<br />
