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?

Characteristics of the Best Shale
1) High organic matter content
2) The right maturity window
3) Sufficient brittleness
4) Sufficient natural fractures
5) 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.

Technology Improvements
![Page 23: My Focus at the REC](https://reader036.fdocuments.us/reader036/viewer/2022081604/5681697c550346895de18557/html5/thumbnails/23.jpg)
Several Technological Improvements Will Affect the Number of Wells Drilled
1) 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.
2) Drilling rigs that “walk” or move along rails will significantly reduce the downtime between drilling a well.
3) The well spacing continues to tighten, leading to more producing wells on a given amount of acreage.
4) Tapping other pay zones will also extend the life of fields.
