REVEAL

REVEAL is designed to study specialised near well bore effects and assess their impact on the production from the reservoir. Most reservoir groups within the oil and gas companies are carrying out specialist studies in areas such as:

• Thermal and mobility studies - injectivity and production
• Production chemistry
• Scaling
• Souring
• Solids and Sanding
• Thermal and hydraulic fracturing
• Steam injection

These studies are often being carried out isolated from the reservoir simulation model. The key role for REVEAL is allow these specialist studies to be integrated with the reservoir simulation models - Eclipse, VIP, etc. - to evaluate the impact on production. REVEAL enables the corporate reservoir simulation model to be used and the effects of these specialist studies to be integrated. As an illustration: What is the impact of injecting cold water - at sea temperature - into a reservoir at 90 to 110 Deg. C. An injectivity test will often show good injectivity. When the injection system is tied in, the ability to inject the water deteriorates dramatically with time. The assumption can be that there is plugging. The reality is that the injected cold water is cooling the reservoir and there is a mobility reduction at the reservoir level. This is a very typical problem found today and is most pronounced in the Deep Water fields. Specialist studies in the above areas are often carried out in isolation. REVEAL is a tool that allows these, often isolated studies, to be evaluated in context of the complete production and reservoir system. REVEAL can bring together the studies of the production chemist, fracturing specialists, sanding and thermal effects... REVEAL can therefore be considered as a tool for integrated reservoir and production studies. Injection of chemicals or fluids at non-reservoir temperature can have significant effects on fluid mobilities and therefore subsequent injectivity and oil production. Specialist Model:
