The newest buzz among offshore operators serving the oil and gas rigs in the Gulf of Mexico (GOM) is the increased use of methanol (CH3OH) by oil companies and contract drillers. This has meant more work for supply boats carrying this alcohol product to rigs along with rig water, fuel oil and liquid and bulk mud. Methanol is used to keep the flow lines from the wellhead to the surface of the water from becoming restricted or blocked. Restricted flow from wells is becoming an increasing problem for oil companies and drilling contractors whose bottom line depends on getting every drop of oil from a well. Flow assurance is a critical issue, especially with longer tiebacks in deepwater drilling operations.
