Oil/Gas/Buying Wells in Operation


Dear Cliff.

I work for a company in Mexico. My boss and his partner want to buy Wells in Operarion.
Since I am new on this subject, I have trouble understanding things like WI,ORRI,NPI...
Is there a mannual, or some place where I should start to get familiar with all these new terms, and also to learn about this subject as much as I can?
Can you recomend a Broker or 2?
Thaks for yor help.

I would suggest that you become a member of as many different associations as you can such as the AAPL (American Association of Petroleum Landmen)  See the following web pages:

These are some very good resources that are available to you.

There is a group here in North Texas that specialize in operating existing fields and re-completing wells in Texas, Oklahoma, and Kansas that you may want to speak with.  They are the only group that I'm aware of that I know well enough to recommend.  

Please contact me at my e-mail address

for additional information.

I will try to answer any question you have. Even if I reject a question, I still will give a shot at what I would do in your position. The only questions I will not take a shot at would be a highly technical engineering or geological question. I am beginning to see quite a few questions from land men and other oil companies and that doesn't matter to me either. I will attempt to help.
