Commercial Deployment of Low-Dosage Hydrate Inhibitors in a Southern North Sea 69 km Wet-Gas Subsea Pipeline

摘要

Theshold hydrate inhibitor (THI) has been successfully commer- cially deployed at a low-dose rate in a wet-gas pipeline connecting the Hydr-West Sole gas fields to the onshore Easington gas ter- minal. These gas fields are BP Amoco operated assets and are located in the U.K. sector of the southern North Sea, approxi- mately 70 km offshore of the Easington gas terminal. Three gas platforms: Hyde, West sole Charlie, and West Sole Bravo, are connected to a common 24-in.-diam flowline to shore and typical gas production lies in the range 50-180 mmscf/d (million stan- dard cubic feet per day).
