Carbonates: New Frontiers Workshop Description
Carbonate oil and gas reservoirs in the Russian Federation are present at all stages of field
development. Shallow carbonate oil fields were discovered in the Timan-Pechora basin in the
1920s, the giant oil, gas-condensate and gas fields of the Volga Urals region were discovered
in the 1940s to 1950s and discoveries continue to be made particularly in the remote regions
of Eastern Siberia and the Northern seas.
The focus on much of the field development activity in the Volga Urals basin is on maintaining
production and improving ultimate recovery. Nevertheless new concepts in field development
of reservoirs with complex pore systems (fractures, karst and mega-karst) are rejuvenating
exploration interest in the region.
In contrast to the situation in South Western Russia, production from deep carbonate reservoirs
in the Timan Pechora basin is relatively recent, and the development of carbonate reservoirs
in the Pechora Sea and Eastern Siberia largely in the planning stage. These areas in the North
and East of Russia are new frontiers for carbonate field development.
The reservoirs in all of these regions contain a variety of fluid types ranging from heavy
oils, to gas-condensate and gas. The majority of oils are medium to light, gas can be sour.
Pore types are similarly variable and understanding the role of fractures and karst critical to
successful field development.
The workshop is organized in three sessions focusing on Carbonate Reservoir Characterization,
Carbonate Reservoir Management, and Carbonate Reservoir Stimulation and Enhanced Recovery.
Workshop Objectives and Deliverables
• To facilitate the interchange of ideas on carbonate reservoir classification, description
and field development
• To present case studies of carbonate fields, identify best practices and areas where new
ideas and technology are required.
• To identify and record optimal recovery strategies from carbonate fields with differing
fluid types, pore types and pressure maintenance schemes
• To determine the limitations of existing technologies and to identify potential
breakthrough technologies to improve recovery from carbonate fields.
Who Should Attend
Meeting attendance will be limited to 70 people in order to facilitate discussion. The
attendees will consist of experts in carbonate reservoir characterization, development and
management and is particularly suitable for professionals from the following disciplines:
• Geologists and Geophysicists
• Petrophysicists
• Production Engineers
• Reservoir Development Engineers
• Well Construction and Completion Engineers

Session One: 0930–1700
Carbonate Reservoir Characterization
Session Managers: Chris Einchcomb

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
