0900–0930 -- SPE Registration
0930–1700 -- Session One: Carbonate Reservoir Characterization
Session Managers: Chris Einchcomb, Victor A. Efimov, and Rustam Tukhtaev
Carbonate reservoirs display a large variability in their characteristics which affects their performance and economic viability. Primary facies distribution (i.e. reef, platform, shallow or deepwater), rock properties (primary and secondary), diagenesis, and fracturing are among the key controls on reservoir performance. The integration of subsurface disciplines can contribute to the understanding and prediction of reservoir performance and depletion strategies. Seismic data integrated with well data are capable of differentiating between reef and platform facies, and, identifying fracture density. In this session we will explore the role of data integration in characterizing carbonate reservoirs through the discussion of a number of case studies. Key topics to be discussed include:
- General controls on reservoir distribution and diagenesis in Russian basins
- The role of seismic data in identifying carbonate reservoir facies and fractures
- The application of wireline log analysis and core analysis to predict and quantify reservoir porosity, permeability and both large and microscale fracturing
- Petrophysical analysis (using log data and borehole imagery) to identify large and micro scale heterogeneities and to predict reservoir properties away from well control

0900–1600 -- Session Two: Carbonate Reservoir Management
Session Managers: Vladimir A Pavlov, Dmitry A. Antonenko, and Felix R Yahshibekov
In common with the rest of the world a significant part of Russia’s hydrocarbon resources are in carbonate reservoirs. The complexity of tectonic structure (faults, fractures etc.) and carbonate deposition characteristics (different wetting conditions, diagenetic processes, etc.) lead to a wide range of development strategies. In general, recovery processes in carbonates are more complex than in clastic reservoirs. Choosing the optimal development and management strategy has to take into account the specific characteristics of the reservoir. To illustrate the range of possibilities we will present case-studies of carbonate field development from Russia and elsewhere in the world. Issues to be discussed during the session include:
- Field Development Optimization [type of well (vertical, deviated or horizontal), well completion, drainage pattern, target bottom hole pressure]
- Pressure maintenance strategies [agent (water, gas, type of gas…), drive mechanism, production and injection rates]

0900–1200 -- Session Three: Carbonate Reservoir Stimulation and Recovery Optimization
Session Managers: Murray Pike and Krešo K. Butula
Stimulation of carbonate reservoirs is a daily occurrence around the world. Russia has reservoirs ranging from developed reservoirs to newly explored reservoirs to potentially yet to be discovered reservoirs. No matter what the stage of development most reservoirs will undergo stimulation and enhanced recovery operations at some stage of their life. Many of the newly explored reservoirs have unique characteristics and pose new challenges to the industry. The workshop will explore some of the technologies used in previous regions through case studies and how we can apply these to the new frontiers. Some of the key topics to be discussed in the session include:
- Requirements for reservoir characterization
- Formation damage and candidate selection principles
- Treatment fluid selection including quality assurance and quality control considerations
- Selecting the correct stimulation technique
- Stimulation evaluation—feedback for improvement
- Optimization of hydrocarbon recovery

1200 -- Workshop Closes
