... This would be the first offshore field developed in the nation by drilling offshore wells from piers -- From Santa Barbara County records 1  NOTE: This appendix is excerpted from American Oil and Gas Historical Society, "Offshore Pe troleum History," http://aoghs.org/offshore-history/offshore-oil-history/, accessed November 13, 2017.

... The Caddo Lake wells -- completed over water without a pier connection to shore -- have frequently been called America's first true offshore drilling. A major petroleum company based in Pittsburgh, Pennsylvania drilled the first "over water" oil well in 1911, according to historian Bob Bowman of the East Texas Historical Association.

... . GULF OF MEXICO TECHNOLOGIES In 1938, Pure Oil and Superior Oil Company built a freestanding drilling platform in the Gulf of Mexico -- despite many logistics, engineering and communications challenges.

... "Whether or not it will ever be economically feasible to explore these waters for the domes that must exist is a question for the future to answer." Kerr-McGee dramati cally answered the salt dome question in 1947 with an experimental offshore rig. Not much equipment specifically designed for offshore drilling existed and exploration remained an extraordinarily speculative and risky business venture.

... NEW OFFSHORE RECORDS By the end of 1949, 11 oil and natural gas fields were found in the Gulf of Mexico with 44 exploratory wells, according to the National Ocean Industries Association, which notes that the industry continued to through the 1950s (Figure D.6)

... . According to a March 2013 article posted at Amusing Planet in 1996, the platform set the Guinness World Record for largest offshore gas platform.

... Bell Helicopters recognized the opportunity and formed Petroleum Bell Helicopters Co.

... The clip -- from Shell Oil Company's Perdido production site -- marks the first sighting of a Mag napinna or "big fin" squid near oil development. Marine biologists now partner with petroleum companies.

... Four percent can be attributed to tanker spills. However, near Santa Barbara, Calif., offshore drilling's worst environmental disaster occurred in 1969 when an undersea well blew out.
