Overview
• Intro • Expandable casing statistics• Case Histories• What’s new
On January 10, 1901 the famous Lucas Gusher blew in. Oil sprayed over 100 feet above the derrick for nine days until the well was capped.
Conventional Well Design
Several to many casing strings in a “tapered”
configuration
Each one decreases “diametric efficiency” by
~20%
What and Where is Solid Expandable Technology? (SET®)

Case Histories
HPHT Well – Deep Shelf GOM
UD High Pressure – DW GOM
HP/HT Well in GOM – 20’ Water Depth
Trouble ZoneMajor pressure regression - Losses
SolutionInstalled 9-5/8" x 11-3/4" expandable
ValueDrilled and evaluated virgin formation with sufficient hole size
High Pressure Well in GOM – 3400’ Water Depth
Trouble Zone Low Margin Drilling in a
DW GOM wellSolution
Installed 7-5/8” x 9-3/8”Preserve hole size to TD
ValueDrilled and evaluated new formations in a frontier environment
MonoDiameter™ and What is it?
The industry demands it: More challenging drilling environments Current available technology is limited Improved ROI Advanced well construction
MonoDiameter™ Defined
Provide successive uniform ID over multiple liners
MonoDiameter™10.4" ID
Successful Field Appraisal Well

program Followed standard
operating procedures Well information
Drilled in Oklahoma Real-life well Completed April 2007
Successful installation First of its kind Continuation possible
DNV Certification
Conclusions – What does this mean to us all?
ERD applications “One size fits all” Reduces the Carbon
Footprint of Drilling Ops Drill a more efficient well
Less cuttings, mud, cement, steel, rig size, etc
Is there a “Depth Limit”?
