Their are a number of ways to invest in gas and oil wells and some can be very risky as well. Unless you are an expert I would recommend buying stock of these types of companies on NYSE or American exchange. I would stay away from penny stocks.
Contact legal firms and landmen who specialize in handling mineral rights, etc. Explain you are interested in forming and financing a limited partnership for gas wells and ask for referral to clients who may be interested.
1. If you own property and mineral rights, sell your mineral rights. 2. Invest in oil company stock. 3. Invest in real estate investment trusts that buy land and sell the oil rights. 4. Invest in companies that build drilling equipment.
You could use a direct approach; find companies that specifically drill gas and oil wells. A company like Unit which drills and manages natural gas wells would be an example.
