What parameters are we interested in?<br />

maturation<br />

Quality; Maturity<br />

very oil prone<br />

oil prone<br />

inert<br />

gas prone<br />

Type II marine shales give<br />

most production<br />

High maturity gives better<br />

gas delivery<br />

It has been suggested that<br />

shale in the gas window has<br />

more gas and improved gas<br />

mobility – modified pore<br />

structure? Reduced kerogen<br />

volume? Microcracks?<br />
