Gas Well Hydrate Control by Sub-Surface Injection of Glycol

Certain gas wells tend to form hydrates in the production tubing. This paper outlines a method developed and used by the Author's company to overcome the problem. The injection of glycol to control hydrates results in sufficient dehydration to allow the gas to be transported through a field-gathering system b a treatment plant. Subsurface injection of glycol also offers a method of introducing corrosion inhibitors into the gas stream. The major operating difficulties have been overccme and the system is now in use in the northeastern part of British Columbia
