Hydrate problems in production - PetroWiki


Natural-gas hydrates are ice-like solids that form when free water and natural gas combine at high pressure and low temperature. This can occur in gas and gas/condensate wells, as well as in oil wells. Detailed reviews of gas-hydrate chemistry, physics, and oilfield engineering are found in Makogon[1] and Sloan.[2] This page focuses on prevention, inhibition, and removal of hydrates in production. Other pages provide more detail on hydrate formation and predicting hydrate formation. Shut-in gas wells are particularly prone to serious hydrate problems, if the well has been producing some water.
