• From “Whip-Stocks” to Steerable “Bottom
Hole Assemblies”
• Demand grew steadily as EOR methods
advancedadvanced
• River crossing technique developed from
the need to lay pipe lines under shipping
channels
• HRW wells resulted from marriage of both

The first HRW installationsThe first HRW installations
• The first HRW were installed and subsidized at large
government sites and chemical plants beginning in the
1980’s
• Some were groundwater recovery wells in clay, in lieu of
excavationexcavation
• First Air Sparge (AS)/Soil Vapor Extraction (SVE) pair was
completed for Department Of Energy
• The wells were expensive and yet effective but at that time
HRWs were not thought of as a viable alternative for most
projects due to cost

1993 Installation of HRW at JFK Airport 1993 Installation of HRW at JFK Airport
was was the Pivot Point the Pivot Point
• JFK was the largest airport in USA in 1993
• Marriage of oilfield know-how with utility rig nimbleness and
efficiency spawned success
• Using smaller drill rigs
dramatically reduced the HRW
installation cost
• Today there are miles of HRW
under JFK airport

For the Next 20 Years, For the Next 20 Years,
HRW HRW Continue Continue to Advance to Advance
- Completion materials
- Well screen design
HRW had growing pains finding the best match of materials, field
conditions, and cleanup objectives:
- Well screen design
- Well development
- Filter pack (natural or
artificial?)
- Drilling fluid management
(recycling is good)

Conclusion Conclusion
• As with the current uses of HRW we are only limited by our
imagination.
• The growth and development of HRW are again only limited
by our imaginations
• The growth and development of HRW will continue because • The growth and development of HRW will continue because
this technology is a powerful and proven remediation tool.
• We encourage you to help us discover new uses and
implementations for this technology.
