Definition - What does Hydrate Formation mean?
Hydrate Formation is a formation that occurs due to the reaction of water with hydrocarbons present in the reservoirs. These hydrocarbons include methane, ethane, propane or hydrogen sulfide, nitrogen and carbon dioxide. Hydrates are solid shaped particles which can be compared to ice and can cause problems in the well operations. These hydrates are solids that are formed when natural gas and water combine at low temperature and high pressure. This may happen in both oil and gas wells.
Petropedia explains Hydrate Formation
Computer programs are used to predict Hydrate Formations in oil and gas wells. Most wells which produce some water (Shut in gas wells) face such problems of hydration. To solve this issue the right temperature and pressure due to which the hydration had formed has to be identified. Computer simulation programs are used to keep a check on the recorded values with the required or permissible limits of hydrate formations. Even in shut in oil wells the Hydrate Formation generates the slurry of solid that accumulates and create problems.
These are some of the factors on which the accumulation of hydrates depends upon:
- The design
- The operating regime
- The fluid composition
- Geothermal gradient
