The Truth ‐ Mississippian Formations are Excellent
Source Rocks
Presenter’s Notes: this slide combines a picture of the “smoking gun”source rock(i didn’t identify where the numbers came from nor did anyone ask). I made the jokethat if you want black source rocks, the effective SR for this play is “blacker thanblack”. PG stands for “pre-generation”– where we correct the numbers back usingorganic matter w/ thermal maturity to estimate the numbers of pre-generation.

• Mississippian and Permian reservoirs
• Source could open up potential in
other states
• Mississippian shale plays could be
developed in new areas
• Additional Navajo Sandstone fields

How to Tell Good Ideas From Bad IdeasHow to Tell Good Ideas From Bad Ideas
• Gather all the data you can, use your instinct to
determine what information is pertinent
• Some information, even though true, doesn’t have a
bearing on the problem your trying to solve
• Think in the big picture
• Failures ‐ dry holes tell a story that can lead to
success
(Chevron Salina
Unit
#1
1981)
• Use all the technology and science you can to discern
good ideas
