My Focus at the REC Addressing these two questions: • How is “unconventional” drilling different from conventional drilling? • How long will (drilling activity in) the Eagle Ford Play last?
What Countries Have the Most Shale Oil and Shale Gas Reserves?

Characteristics of the Best Shale • High organic matter content • The right maturitywindow • Sufficient brittleness • Sufficient natural fractures • Good porosity
Definitions • Porosity - the percentage of void space in a material. • Permeability – The property of a porous material to permit a liquid or gas to pass through it.

What Shale Rock Looks Like The pct. of O&G being recovered from the shale is relatively small.

Several Technological Improvements Will Affect the Number of Wells Drilled • Drilling one well to “hold a field by production” giving way to “pad drilling” where multiple wells are drilled from one drillsite, saving time and money. • Drilling rigs that “walk” or move along rails will significantly reduce the downtime between drilling a well. • Thewell spacing continues to tighten, leading to more producing wells on a given amount of acreage. • Tapping other pay zones will also extend the life of fields.
