This document summarizes a sequence stratigraphic interpretation and play fairway analysis project conducted by TGS in the Labrador Sea utilizing seismic and well data. The project aims to provide a geologic model of basin deposition over time, delineate reservoir and seal distributions related to tectonic activity, and identify prospective hydrocarbon leads. TGS integrated well log and seismic data to define a sequence stratigraphy framework and map 14 depositional sequences. Interpreted data is delivered in various formats along with maps, horizons, faults, and a report summarizing the project, basin modeling, and fluid modeling. Benefits include a foundational exploration tool, shortened exploration timelines, insights into regional deposition, reduced risk through source-reservoir

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 Labrador
Sea seismic survey data and available well data to:
ƒƒ Provide a geologic model of the depositional basin fill
throughout 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, AVO analysis and fluid
reservoir modeling
In addition, TGS has integrated and interpreted well log data
to define a sequence stratigraphic framework. Depositional
environments and associated facies are interpreted based on
log character for available wells. Where insufficient well data
is available, seismic facies analysis has been used to define
the gross depositional environments. Gross depositional
environment maps for 14 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 called the Facies Map Browser (FMB), which can be
used to review all well and map data.
Deliverables 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
The structural interpretation deliverables include:
ƒƒ Structure and isopach maps
ƒƒ Horizons
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 featured. A report summarizing the
current seismic based interpretation projects, basin modeling,
and fluid reservoir modeling has also 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.
