Use of TEG-MeOH To Control Wellbore Hydrate Formation

Kenneth Sheeran, Michael V. Murray

Publisher: Society of Petroleum Engineers (SPE)

J Pet Technol 65 (06): 26–29.

Paper Number: SPE-0613-0026-JPT

... is there a downhole chemical dosing point. On each Christmas tree between the master and wing valves, there is a chemical injection point (fed by two umbilical cores), a pressure sensor, and a temperature sensor. The hydrate inhibitor historically used was methanol (MeOH). No corrosion inhibitor is injected...

Hydrate Prevention using MEG instead of MeOH: Impact of experience from major Norwegian developments on technology selection for injection and recovery of MEG

S. Brustad, K.-P. Løken, J.G. Waalmann

Publisher: Offshore Technology Conference

Paper presented at the Offshore Technology Conference, May 2–5, 2005

Paper Number: OTC-17355-MS

DOI: https://doi.org/10.4043/17355-MS

... Ethylene Glycol). A comparison between MEG and MeOH is presented. Advantages, limitations and cost elements (CAPEX/OPEX) by use of glycol (MEG) vs. alcohols (Methanol/Ethanol) are reviewed and discussed in relation to their applicability. Based on experience, typical operational problems within closed...
