Creating Subterranean Channels and placing Pipelines and Well Jumpers within these channels at a depth below seabed where the ambient heat in the subsoil is above the Hydrate formation and Wax Appearance temperatures, will assist the reduction in the formation of these undesired formations which can block the pipes and stop the flow of hydrocarbons.
Routine maintenance with Pigging is necessary to remove wax build-ups on the pipe wall this requires production to be interrupted. With Subterranean Pipelines the flowing hydrocarbons will be constantly above the Wax Appearance Temperature.
Hydrates form when the hydrocarbons drop below a formation temperature and this can also block the flow. Subterranean Pipelines will maintain the flowing hydrocarbons above the Hydrate formation temperature with no artificial heating, and a much longer shut-in cool-down time. Less chemical Inhibitor injection and less chemical recovery will mean a reduction in FPSO operating costs.
