Post-salt

Brazils post-salt reservoirs aregenerally found in sandstoneformations, but may also exist incarbonates. Most of the discoveries inBrazil have been made in the post-saltgeological layer of the Campos Basin,where heavy oil predominates.

RESERVOIR Improve exploration success rate

using volume interpretation andvisualization

Increase recovery factor

WELL ENGINEERING Increase drilling tool reliability in

ultra-deep wells in hard formationenvironments

Boost productivity with optimalwell placement

Alleviate environmental risksusing synthetic-based,high-performance fluids

Mitigate risk and improveproduction by managing reservoirwith intelligent completions andmultilaterals

Enhance production by fracingdeep, long horizontal wells

Improve productivity with hydrau-lic fracturing in tight gas sands

Achieve high-rate gas wellcompletions

FLOW ASSURANCE Increase production by keeping

wells free of scaling, paraffin, andhydrate

Pre-salt

Brazils pre-salt reserves are found incarbonate formations and can beburied below as much as 6,500 ft(2,000 m) of salt. Although the pre-saltpotential is great, along with thetremendous opportunities are a hostof new, complex challenges that mustbe addressed.

RESERVOIR Improve facies definition using

seismic data Evaluate reservoir for internal

characterization Reinject water and/or gas for

secondary recovery Predict reservoir compaction

behavior as it is depleted

WELL ENGINEERING Improve performance in deviated

wells in the salt zone Increase ROP in the carbonate

reservoirs Place well in most productive

reservoir interval Maximize recovery using hydraulic

fracturing in horizontal wells Manage reservoir with intelligent

completions and multilaterals Insure well integrity in reservoirs

with high content of H2S and CO2

FLOW ASSURANCE Increase production by keeping

wells free of scaling, paraffin, andhydrate

Halliburton Answers

The potential of Brazils deepwaterassets is huge, and the pace ofoffshore development is growing.Current and future discoveriesdepend on a broad scope oftechnologies and capabilities as wellas an experienced service companywith reliable and proven technologyto achieve economical andoperational success.

Halliburton has drilled hundreds ofdeepwater wells in Brazil, includingmost of the pre-salt wells drilled todate. Success in these giant fieldsrequires rapid prospect identification,the ability to properly evaluate thereservoirs potential and to efficientlydrill the well. Halliburtons reliableservice capabilities and provendeepwater technologies are helpingspeed development, improveefficiencies, and increase productionin these important plays.

Visit www.halliburton.com for anin-depth look at how Halliburton isdriving deepwater success in Brazil.

Exploration offshore Brazil is centered on three basins: the Santos, the Campos, and the Esprito Santo. A salt layer overlies parts ofeach basin and can vary from 656 ft (200 m) to 6,562 ft (2,000 m) thick. Reserves in Brazil are characterized by their location relative tothe salt deposits. Reserves that exist above the salt are referred to as post-salt; those existing below the salt are defined as pre-salt.
