Well Stimulation Tool [Data Sheet]
The Well Stimulation Tool is an alternative process for carrying out stimulation projects on producing subsea wells. The system is deployed, operated, controlled, and recovered from a Multi-Service Vessel (MSV) or Diving Service Vessel (DSV) and eliminates the need for a work over rig and surface riser. Fluids are delivered to the well via a dual coil tubing unit located on the vessel.
Deployed by a Remotely Operated Vehicle (ROV) system, the deepwater tool offers customers a proven non-traditional method for interventions that can reduce project costs. The subsea tool moves oil and gas technology forward and advances standard intervention practices.
PAR Drilling Tool [Data Sheet]
Oceaneering has designed a PAR Drilling Tool for high pressure, high temperature wells that allows the operator to install normal casing. This tool relieves pressure build-up in the annulus around the production casing due to operation of the wellhead. It plugs the drilled hole and prevents sea water ingress into the annulus. The plug is connected to a hydraulic panel by means of a hot stab that monitors the pressure build-up in the annulus and can also relieve any future pressure build-ups. The hydraulic panel includes a pressure gauge, a pressure transducer, and a 3-way ROV operable valve for a panel operation. The pressure transducer plugs into the control pod on the subsea tree monitoring the pressure inside the annulus from the surface.
TA Cap [Data Sheet]
Oceaneering manufactures a Remotely Operated Vehicle (ROV) friendly light weight TA cap that requires no additional deck equipment during installation or removal. The light weight TA cap is constructed of aluminum and weighs only 75 lb in water, allowing the ROV to easily deploy and recover the cap without additional topside support equipment. Wellheads can now be protected with a sealed void that can be filled with corrosion fluid by ROV intervention. A topside winch, air tugger or a crane fast line for installation or removal is no longer required with these caps.
A three-coat paint system with extra topcoat, along with Delrin inserts, ensures that the cap is isolated from the wellhead to eliminate corrosion due to galvanic reaction. Four stainless steel T-handles with Delrin shoes secure the TA Cap to the wellhead in order to prevent metal-to-metal contact with the wellhead. Once secured, the ROV can pump required corrosion inhibitor fluid into the TA Cap. A check valve ensures that water is fully displaced by the corrosion inhibitor fluid and provides visual confirmation.
Light weight TA caps can be custom built to fit most wellhead types and sizes.
