Glossary

The Kallanish Glossary aims to be a useful resource for complex industry specific terminology. We are constantly adding to our glossary, so if you have a suggestion or amendment please do get in touch.
Unassociated Gas

Natural gas occurring alone, not in solution or as free gas with oil or condensate.

Upstream

Upstream operations deal primarily with the exploration stages of the oil and gas industry, with upstream firms taking the first steps to first locate, test and drill for oil and gas. Later, once reserves are proven, upstream firms will extract any oil and gas from the reserve. Most large oil companies are known as "integrated" because they combine upstream activities with midstream and downstream operations, which take place after the production phase through to the point of sale.
