Just a quick observation and comment regarding the difference between Landmen and Real Estate professionals in the Oil & Gas space. The difference in skillset is significant however they can complement each other in down times. I obtained my Brokers License in 1986 during one of the worst crashes in our industry and it was a Godsend. Commercial transactions (not residential) paid handsomely and that experience introduced me to telecom where I flourished and remain.
My recommendation (and I'm not alone) is to take the shades off, diversify and gain experience in complementary land related industries.
I am a 40 year Landman who has had a real estate license in Texas for almost seven years. Fortunately I saw the downturn coming and diversified my income stream. The skills I acquired doing land work have been invaluable to my real estate practice because very few agents have my skill set. While my oil and gas consulting income is down to a trickle, I am making really good money selling farms and ranches. Mr. Brock is correct in that a real estate agent is not a landman, nor is a right of way agent or division order analyst a landman. However, if you are a good landman then you have the skills to sell real estate, calculate division of interest, cure title, close transactions, or any number of things. Look at what people who are like you (have similar interests and backgrounds) do for a living and pursue what you enjoy.
