As with most industries, the oil and gas industry has a language of its own that investors will need to learn and understand if they want to be successful.
At first glance, these terms can seem rather confusing, but OilInfo.org has created a free oil and gas industry glossary of terms to help newcomers and experienced veterans alike.
This glossary will cover as much industry terminology as we can come up with, from the exploration and production companies that search, discover and produce the resources, to the drillers that “pull” the oil or gas out of the ground, to the refiners that take oil and turn it into the useful forms we see everyday. When browsing, you will find commonly used terms and definitions that will assist you in becoming acquainted with the different areas of the industry and understand your investment opportunities better.
