TGS has generated a sequence stratigraphic interpretation and play fairway analysis project for the Northeast Newfoundland Shelf utilizing new seismic survey data and available well data. They mapped 21 sequences and delineated reservoir distribution over time. Deliverables include structure maps, horizons, leads, faults, and depositional environment maps. The benefits are a reduced exploration cycle time and risk through understanding basin development and delineating source, seal, and reservoir distributions. Clients must license 50% of the underlying seismic data.

Sequence Stratigraphic Interpretation and Play Fairway Analysis
PROJECT DETAILS
TGS has generated a sequence stratigraphic and play fairway
analysis interpretation project utilising the new TGS Offshore
Northeast Newfoundland Shelf seismic survey data and available
well data to:
ƒƒ Provide a geologic model of the depositional basin fill over time
ƒƒ Delineate the presence, thickness and distribution of reservoir
and seal with respect to timing and movement associated with
tectonic activity
ƒƒ Identify and risk-assess prospective hydrocarbon leads by
performing basin modeling and AVO analysis
In addition, TGS has integrated and interpreted well log data
to define a sequence stratigraphic framework. Depositional
environments and associated facies will be interpreted based on
log character for available wells. Where insufficient well data is
available, seismic facies analysis will be used to define the gross
depositional environments. Gross depositional environment maps
for up to 21 sequences have been interpreted and mapped.
DELIVERABLES
Interpreted seismic and well data are delivered in shape, image and
ASCII file formats. TGS also provides clients with a viewer, the Facies
Map Browser (FMB), to review all well and map data.
Deliverables will include:
ƒƒ Processed well curve data
ƒƒ Sequence boundaries picked on log data
ƒƒ Seismic horizons used to define and constrain sequence boundaries
ƒƒ Gross depositional environment maps based on well and seismic
events
ƒƒ Seismic facies maps
ƒƒ Reservoir, seal, and play fairway summary maps
ƒƒ Core descriptions and cor summart report for 9 wells
The structural interpretation deliverables include:
ƒƒ Structure maps
ƒƒ Horizons
ƒƒ AVO analysis
ƒƒ Leads and features
catalogue
ƒƒ Fault segments
ƒƒ Fault polygons and
polygons that delineate
potential hydrocarbon
anomalies.
Other geologic features such as areas of igneous activity and
major depositional features such as deltas, fans, debris flows and
turbidites are also identified and interpreted. A report summarizing
the current seismic based interpretation projects and basin
modeling has been prepared.
BENEFITS
The benefits of the sequence stratigraphic study and play fairway
analysis are:
1. A fundamental exploration tool that takes many man years to
complete and therefore few companies complete in such detail
2. A fast track understanding of basin development and shortened
exploration cycle time
3. New and extended insight into the gross depositional
environments of the region
4. Reduced risk through delineating source, seal and reservoir for
use in predictive exploration
5. A robust framework for play modelling and exploration work
6. Integrated data in a single environment to improve productivity
REQUIREMENTS
Clients must license 50% of underlying seismic data.
