Channel Architecture Reservoir Database (CARD™)
For Immediate Release 7th of February 2008 - C&C Reservoirs, the premier provider of global field/reservoir
analogs delivered via the web-based DAKS, is pleased to announce the addition of a new series of analogs studies on 
reservoir architectural elements.
CARD™ (Channel Architecture Reservoir Database) is the first phase of an extensive programme to
provide comprehensive reservoir architectural data within the DIGITAL ANALOGS™Knowledge System (DAKS). These data,
in combination with published reviews of subsurface, outcrop and modern analog data, will provide a framework for
comparison of channel reservoir architectures worldwide. CARD will provide essential information in the drive to
improve predictability of reservoir dimensions, connectivity, compartmentalization and productivity and will involve
the compilation of dimensional and reservoir characteristics parameters from a wide variety of sources. A synthesis
of these data will be generated for the characterization of channel sand reservoirs worldwide. Data will be derived
from fields in DAKS, and published reviews of subsurface, outcrop and modern analogs.
CARD will allow users to review:
(1) Gross channel dimensions and variability;
(2) Internal geometries, lithofacies, architecture and reservoir quality variations;
(3) Internal compartmentalization and shale barrier distribution;
(4) Channel stacking patterns and inter-channel connectivity;
(5) Water flooding and sweeping characteristics both vertically and laterally in relation to various channel sand and development stage
(6) Oil and gas productivities in relation to the above;
(7) Comparison of channel geometries and productivities in a range of depositional environments: fluvial (low- and high-sinuosity), deltaic, tidal, turbiditic and lacustrine.
Results from CARD will be used in field development planning and production enhancement to
Provide knowledge for optimizing EOR targets and as input for geological modelling
Determine well pattern and spacing
Assist in step-out and infill drilling
Identify remaining oil from mature field
Parameters to be presented in CARD will include (where available):
Channel width (including information on downdip variablity)
Channel thickness (including information on downdip variablity)
Dimensions of component facies
Ratio of width vs. thickness
Meander wavelength to channel-width ratio
Sinuosity
Braiding index
Lithofacies
Net to gross
Porosities
Permeabilities
Variogram range (vertical and horizontal)
Heterogeneity indices (mesoscale and microscale)
Lithofacies architecture
Vertical and lateral channel stacking patterns
Channel compartmentalization
Inter-channel connectivity
Channel to sheet sand connectivity
Shale barrier dimensions
Shale barrier density (number of barriers per meter)
Productivity indices
CARD deliverables will include
1) Database for channel sand reservoirs (outcrop, subsurface and modern),
2) Detailed classification of various type of channels at field, reservoir and fluid unit scale along with a synthesis report for each channel type with statistical analysis and production-engineering applications and
3) Web-based knowledge platform for searching and analyzing of architectural element data.
CARD will be fully integrated in DAKS platform that has been widely adopted by the industry as the premier platform for analogs.
The first phase of CARD will be completed by Q1, 2009
