Miocene

Targets in the deepwater Miocenetrend have generally been influencedby salt intrusion, making reservoirgeology difficult to understand.Projects in the development phasemust balance increased wellcomplexity with a desire to reducedrilling and completion costs.

EXPLORATION:• Seismic imaging in narrow

mini-basins• Sand identification

DRILLING:• Narrow drilling margin• Borehole stability challenges• Complex well trajectories in

development projects• Improving drilling efficiency

COMPLETION AND PRODUCTION:• Unconsolidated formations• Cross flow between wells

due to extensive faulting• Production declines that

must be offset with methodsto enhance recovery

Lower Tertiary

The LowerTertiary trend is generallycharacterized by older sediments withlower porosities, ultra-deepwaterdepths, reservoir depths greater than26,000 ft and high bottomholepressures.

EXPLORATION:• Limited geologic/analogue

well information• Lack of reservoir modeling

DRILLING:• High well costs• Narrow drilling margin• Extreme reservoir depth

COMPLETION AND PRODUCTION:• High completion cost• Low reservoir porosity and

variances in permeability• Economic challenges due to

reservoir quality and flowcapability

Salt Canopy

The extensive Salt Canopy greatlyimpacts seismic imaging quality.Salt bodies present unique wellplanning demands, slow drillingprogress and require highlyengineered completion solutions toensure long-term well productivity.

EXPLORATION:• Seismic attenuation• Depth imaging below salt• Defining base of salt• Locating and identifying inclusions

DRILLING:• Drilling optimization through salt• High vibration and shock• Salt exit strategy• Unexpected “tar” deposits

COMPLETION AND PRODUCTION:• Casing size limitations• Salt creep• Reservoir compartmentalization• Reservoir compaction with

pressure depletion

Halliburton Answers

The complex challenges presentedby the Miocene and LowerTertiarytrends, coupled with the Salt Canopyin the deepwater Gulf of Mexico, areimmense.This table merely sug-gests a few.

The answers are equally complex.Shaped by geologic and economicextremes, they require an all-inclusiveperspective that leverages everycapability across all disciplines.

Success in deepwater environmentsalso calls for a service company withreliable and proven technology, alongwith the experience and customercommitment to achieve efficienciesthrough the entire process, for thelife of the well.

At Halliburton, we understandthe critical operating challengespresented in these tough environ-ments. Join us at www.halliburton.comfor an in-depth look at how we canhelp you succeed in the deepwaterGulf of Mexico.
