TGS provides geoscience consulting services for the Santos, Campos and
Espirito Santo basins in southern Brazil.
PROJECT DETAILS
TGS has completed an in-depth sequence stratigraphic analysis based on
detailed well log data interpretation of key exploration wells.
ƒƒ 109 wells in the Santos project
ƒƒ 224 wells in the Campos/Espirito Santo project
In addition, TGS has defined a sequence stratigraphic framework for each
basin based on the integrated and interpreted well log data. Depositional
environments and associated facies have also been interpreted based on log
character for available wells.
Gross depositional environments have been interpreted and mapped for each
basin.
ƒƒ 26 gross depositional environment maps in the Santos project
ƒƒ 38 gross depositional environment maps in the Campos project
All interpretations and maps have been tied to TGS 2D seismic across
each basin. This seismic data has been further interpreted to provide a
comprehensive seismic facies analysis. This helps to identify the distribution of
reservoir, source and seal units.
Furthermore, a presalt prospectivity study has been completed which provides
volumetric calculations and risking parameters for the hydrocarbon leads
identified from the play fairway analysis.

DELIVERABLES
The sequence stratigraphic interpretation, including
all well data, well tops, well interpretation and
gross depositional environment maps are delivered
via TGS’ proprietary Facies Map Browser (FMB)
interface platform.
The deliverables from the seismic interpretation, facies
analysis and prospectivity study include:
ƒƒ Detailed seismic facies analysis
ƒƒ Timing of salt and fault movement
ƒƒ Timing and impact of volcanic activity
ƒƒ Reservoir distribution risk maps
ƒƒ Top seal integrity distribution risk maps
ƒƒ Identification of prospective leads
ƒƒ Catalog of leads and analogs
ƒƒ Basin temperature modelling
ƒƒ Heavy oil risk analysis
ƒƒ Composite trap summary maps
BENEFITS
The benefits of the complete study 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. Enhanced understanding of prospectivity and
potential of the area
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.
