Wellhead P&A includes isolating the oil gas layer from the aquifer, sealing the well to prevent oil and gas from leaking into the sea, and removing wellhead components.
All wellheads require plugging and abandon (P&A) at the end of the production cycle, and P&A accounts for 40% of the total cost of platform decommissioning for some platforms. Wellhead P&A includes isolating the oil gas layer from the aquifer, sealing the well to prevent oil and gas from leaking into the sea, and removing wellhead components. Wellhead abandon requires placing enough sealing media in the wellbore to ensure that the well is permanently sealed, which is a challenge in deep waters, especially wet wellheads on the seabed.
Based on the rig less wellhead P&A technology, Jereh Offshore can provide engineering equipment and technical services including wellhead sealing, wellhead recovery, oil casing recovery, etc.
With advanced rig less P&A systems, P&A costs can be greatly reduced. Rig less P&A systems include workforces, auxiliary ships, rig less lift systems, cranes or casing jacks, logging equipment, high-pressure pumps, liquid handling tanks, gas-liquid separators (to separate oil and gas coming out of the wellhead from the liquid), cementing mixers, mud mixers, cutting equipment, and coiled tubing equipment.
Jereh Offshore can provide conventional and problem well P&A program design and technical services, including wellbore sealing, wellhead cutting, casing cutting, casing lifting recovery.
Platform decommissioning include surface topside removal and underwater structure removal. A lot of cutting operation is needed during the decommissioning.
All the deck will be removed for the fixed platform. Floating platform will be dragged to or nearby the seacoast.
