TGS is offering geoscience consulting services for the Foz do Amazonas,
Pará-Maranhão, Barreirinhas, Ceará and Potiguar basins in northern Brazil.
PROJECT DETAILS
TGS has completed a structural interpretation utilizing 59,944 km of long-offset
2D PSTM seismic data. Hydrocarbon anomalies and geologic features,
such as areas of igneous activity and major depositional features (i.e. deltas,
fans, debris flows and turbidites) have been mapped. The project comprises of
16 seismic horizons and associated faults which have been interpreted.
In addition, TGS is integrating and interpreting 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 up to 20 sequences have been interpreted and mapped. Where
possible, reservoir risk maps have been interpreted.

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 for the structural interpretation include structure and isopach maps,
horizons, fault segments, 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 has been prepared.
Deliverables for the sequence stratigraphic interpretation and play fairway
analysis include processed well curve data, interpreted lithologies, synthetic
seismograms and sequence stratigraphic and play fairway maps.

BENEFITS
The benefits of the sequence stratigraphic study delivered via the Facies Map
Browser (FMB) 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 underlying seismic data and available well data for the
areas of interest.
