Hi Talla,
Your first step is patent the invention. Obtaining the patent will help to protect your rights in its use and employment later.
Talk to a local attorney about some kind of 'non-compete' agreement you could use while the patent application is being processed.
Epa.gov/recovery
Recovery.gov
Grants.gov
These links may also give you some ideas. EPA would be the govt agency to contact for leads to companies who might want to see your invention.
You could also google oil company contacts and email them with inquiries.
State offices in environmental protection would also be a source of info.
Good Luck!
