Session 1. Carbonate Reservoir Geology and Classification
Carbonate reservoirs display a large variability in their characteristics. Most of the carbonate reservoirs, unlike clastic deposits, originate situ in siting and then undergo various post-depositional alterations, which may reflect in basin productivity whether negatively or positively. It causes significant uncertainties in reservoir characteristics forecast and selection of profitable development system. Facial heterogeneity of carbonate formations, alterations of varying intensity and direction in lithogenesis are among keys that control reservoir performance.
Session 2. Carbonate Reservoir Modeling
Geological and filtration modeling helps to mitigate development risk and develop complex reservoir optimum way. Carbonate reservoir structural style due to secondary alterations of pore structure as a result of secondary processes display requires an unconventional approach to modeling. Integration of geological disciplines can help to understand and forecast reservoir performance and to determine development strategy.
Session 3. Carbonate Reservoir Development
Carbonate reservoir development is associated with fracturing, complex structure of deposits (Ex., high-amplitude reef), low porosity, conservative approach to stimulation (hydrochloric acid), and difficulties of efficient formation-pressure maintenance system due to water mobility and dual porosity of reservoir.
Accurate analysis and reserves recovery reasoning require advanced study, apart from the standard set of studies. Advanced studies include multi-rate pilot development, observation well testing coupled with special core tests, well logging and 3D seismic results.
Session 4. Carbonate Reservoir Stimulation and Recovery Optimization
Efficient Carbonate Reservoirs development requires complex approaches and innovative methods. Russia has reservoirs at all stages of development. Most of the greenfields have unique characteristics and pose new challenges to the industry. At the same time, mature carbonate assets are still a significant part of oil production, and they claim as much attention as green fields. The workshop will explore cases to highlight assessment, advanced technologies for production stimulation and how we can apply these to the new frontiers.
Round Table: Undeveloped Reserves: Production Prospects
New technologies together with tax privileges allow encroaching on such carbonate reservoirs, which have been considered unprofitable. During the open discussion we will talk about:
