Circulation obviation retrofit kit (CORK) Schematic

The Deep-Sea Drilling Vessel Chikyu, operated by the Japan Agency for Marine-Earth Science and Technology (JAMSTEC), has successfully completed Integrated Ocean Drilling Program (IODP) (*1) Expedition 332: NanTroSEIZE Stage 2: Riserless Observatory-2(*2), on 11 December in the Kumano Basin, off the Kii Peninsula. The expedition successfully deployed a long-term borehole observatory, which was developed as part of the ocean and earth exploration system, a project pursued as one of Japan’s “Key Technologies of National Importance”. Especially in event of earthquakes, the realtime near-field geophysical observations and retrieval of data will provide invaluable insights into the mechanism of great earthquakes.

Plug installation system for deep water subsea well

A plug retrieval and installation tool is used with a subsea well having a production tree, a tubing hanger, a passage that extends vertically through the tubing hanger and the tree, and a plug located within a plug profile in the passage within the tubing hanger. The plug retrieval device has a housing and connector that is lowered on a lift line onto the upper end of the tree. An axially extensible stem in the housing is driven by drive mechanism into the production passage of the tubing hanger. A retrieval member mounted to the stem engages the plug and pulls it upwardly in the passage while the stem is being moved upward. The connector, drive mechanism and retrieval member are powered by an ROV

Offshore Drilling - Detail

Offshore Drilling and What Can Go Wrong

The Deepwater Horizon blowout in the Gulf of Mexico was not an isolated event. The exploding rig was especially tragic, but the truth is that the oil industry produces pollution every day. In fact, the little spills associated with oil extraction, transportation, and consumption add up to about 195 million gallons every year. That's as much as one Deepwater Horizon gusher
