Ocean Ranger was a semi-submersible mobile offshore drilling unit that sank in Canadian waters on 15 February 1982. It was drilling an exploration well on the Grand Banks of Newfoundland, 267 kilometres (166 mi) east of St. John's, Newfoundland, for Mobil Oil of Canada, Ltd. (MOCAN) with 84 crew members on board when it sank.
Ranger began drilling test wells in the fall of 1972 in the various blocks it had been awarded. In early January 1974 the semi-submersible drilling rig Sea Quest discovered oil in the Ranger-BP block 3/8 at a depth of 10,572 feet. [6] Shortly thereafter, the Burmah-Chevron group discovered oil in the adjoining block, 3/3, indicating a major field.
The rigs usually travel in a convoy, because all of the component rigs are needed for proper oil well servicing. The crew use the equipment on the rigs to provide a variety of services, including completions, work-overs, abandonment's, well maintenance, high-pressure and critical sour-well work and re-entry preparation. Offshore oil rigs are ...
The Ranger Oil Boom started on October 17, 1917, after oil was discovered 3,342 feet (1,019 m) below ground at the J.H. McCleskey No. 1 drill well in Ranger, Texas. The strike was notable because Soviet Russia's threatened exit from World War I meant its oil output was lost to the Allies. Before WWI Russia accounted for 30% of the world's oil ...
In 1982, Ocean Ranger, one of the company's oil platforms, sank in a violent storm in Canadian waters east of Newfoundland, killing 84 people. [4] [5] Also in 1982, the company took delivery of Odyssey. The rig suffered a blowout in 1988. [6] In 1991, Murphy Oil acquired the company. [7]
With high-performance jackup rig rates in 2015 of around $177,000, [25] and similar service costs, a high pressure, high-temperature well of duration 100 days can cost about US$30 million. Onshore wells can be considerably cheaper, particularly if the field is at a shallow depth, where costs range from less than $4.9 million to $8.3 million ...

Gas lift well: gas is fed into valves installed in mandrels in the tubing strip. The hydrostatic head is lowered and the fluid is gas lifted to the surface. Single-well alternate completions: in this instance there is a well with two zones. In order to produce from both the zones are isolated with packers.
