Oil and Gas Landman audio program

I would like to buy an audio program (tapes, Cds, DVDs or MP3) to learn about oil and gas leasing. Is there an audio landman program? I am not interested in being a landman but I need to learn.

go to AAPL website: landman.org ... on the home page is an icon for $50 textbook: "Oil & Gas Land Leasing, etc." prvides a good primer of study

also, there are down-load papers of specific interests (ie: land/regulatory issues of horizontal drilling) under the "Education" button
