A substantial amount of oil and gas reserves are trapped in fractured reservoirs. It is estimated that production from fractured “unconventional” hydrocarbon reservoirs will grow to 20 MMBO per day by year 2030 and contribute 17% of the world’s daily oil production, with equal or even larger contribution foreseen for gas. These unconventional systems, such as tight gas reservoirs and shale-gas plays, are becoming increasingly economical due to the advent of new technological breakthroughs in both Geosciences and Engineering. Estimation of reserves and production performance in these systems present difficult technical challenges but are fundamental to assessing their viability.Moreover, an additional percentage of the original oil and gas in place in fractured conventional reservoirs may be available for recovery provided new technologies and workflows can be applied in a cost effective manner: fractured carbonate reservoirs are considered to be extremely challenging in terms of seismic characterization and detection to predicting reservoir performance. Even in conventional reservoirs, characterization is performed using mostly qualitative analyses whereas production and reserves predictions require quantitative modeling and simulation. Current reservoir simulation practices mostly ignore the geomechanical effects caused by variation in pore pressure during production: these introduce a 4D component to reservoir performance that is poorly addressed at present. Bridging these gaps is challenging and there are many areas that are poorly understood or can only be represented with high uncertainty. Ultimately, all the necessary information is integrated in a geocellular reservoir model, scaled up, and then simulated to quantify the impact of fractures and predict reservoir performance.
Aims of the Workshop
This workshop will focus on the key issues and challenges in two main technical domains, static, and dynamic:
- The detection, characterization, and modeling of fractures and fractured reservoirs, and
- The understanding of the relationship between reservoir matrix and fractures in terms of fluid flow and hydrocarbon recovery, and the simulation of these systems for performance prediction.
Who Should Attend?
EAGE invites experts from oil companies, services companies and academia to interact and debate on the technical issues addressing challenges on production performance of both conventional and unconventional fractured reservoirs. We encourage participation from:
- Reservoir Engineers
