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%

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

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”?
