Direct Electrical Heating unblocks oil and gas pipelines

Blocked oil and gas pipelines is one of the industry’s big anxieties, because of loss of revenue. It has therefore been important to find solutions for oil and gas pipelines to avoid such incidents. The solution is Direct Electrical Heating (DEH).

Blocked pipelines/reduced flow in the pipelines are normally caused by hydrate formations and wax deposition on the pipe wall.

SINTEF Energy Research have developed the DEH method where currents are conducted through the steel pipe. The method leads to asignificant reduction of chemicals injected in conventional methods for unblocking pipes.
