The "Golden Lane" ("Dos Bocas-Alamo structure" or The Ridge") refers to a series of oil fields aligned in an arc onshore and a symmetrical alignment offshore, forming two sides of a [[Cretaceous]] [[atoll]] 180&nbsp;km long.<ref name="Viniegra O. p. 309">Viniegra O., L., and Castillo-Tejero, C.,Golden Lane Fields, Veracruz, Mexico, in Geology of Giant Petroleum Fields, Tulsa: American Association of Petroleum Geologists, Memoir 14, p. 309, 1970.</ref> The structure was discovered in 1908 by [[Weetman Pearson]]'s [[Mexican Eagle Petroleum Company]] San diego de la Mar No. 1 well, which flowed 2,500 [[Barrel (unit)|bbl]]/day.<ref name="Viniegra O. p. 309"/> The Golden Lane oil fields penetrate a massive elliptical [[reef]] platform, identified as the Sierra del Abra limestone (consisting of reef, backreef and [[lagoon]]al [[facies]]), which dips southeast.<ref>Viniegra O., L., and Castillo-Tejero, C.,Golden Lane Fields, Veracruz, mexico, in Geology of Giant Petroleum Fields, Tulsa: American Association of Petroleum Geologists, Memoir 14, pp. 314 and 316, 1970.</ref> The site for the discovery well was selected due to the presence of [[petroleum seep]]s, just as was [[Edward Laurence Doheny]]'s La Paz No. well in the Ebano-Panuco petroleum district west of [[Tampico]], Tamaulipas, the first Mexican discovery well in 1904.<ref>Viniegra O., L., and Castillo-Tejero, C.,Golden Lane Fields, Veracruz, Mexico, in Geology of Giant Petroleum Fields, Tulsa: American Association of Petroleum Geologists, Memoir 14, pp. 309-311, 1970.</ref> In 1908, the infamous [[Dos Bocas oil fire]] occurred after the San Diego de la Mar No. 3 [[Blowout (well drilling)|blowout]].<ref name="Viniegra O. p. 311">Viniegra O., L., and Castillo-Tejero, C.,Golden Lane Fields, Veracruz, Mexico, in Geology of Giant Petroleum Fields, Tulsa: American Association of Petroleum Geologists, Memoir 14, p. 311, 1970.</ref> This was followed by the Potrero del Llano No. 4 well, flowing 100,000 bbl per day during the three months it was out of control.<ref name="Viniegra O. p. 311"/> Doheny's Cerro Azul No. 4 well, located by Ezequiel Ordonez, became the largest daily production record holder in 1916 at 260,000 bbl.<ref name="Viniegra O. p. 311"/> Geophysical studies, in particular [[gravimetry]], starting in 1920 led to the discovery of the Poza Rica Field in 1932 and Moralillo Field in 1948, on the west flank of the Golden Lane in the Tamabra forereef facies.<ref>Viniegra O., L., and Castillo-Tejero, C.,Golden Lane Fields, Veracruz, Mexico, in Geology of Giant Petroleum Fields, Tulsa: American Association of Petroleum Geologists, Memoir 14, pp. 311 and 317, 1970.</ref> Refraction [[seismography]] surveys started in 1930, augemented in 1948 with reflection seismography, which led to the discovery of the southern extent of the atoll with the Ezequiel Ordonez No. 1 well in 1952 and additional discoveries through 1968.<ref name="Viniegra O. p. 312">Viniegra O., L., and Castillo-Tejero, C.,Golden Lane Fields, Veracruz, mexico, in Geology of Giant Petroleum Fields, Tulsa: American Association of Petroleum Geologists, Memoir 14, p. 312, 1970.</ref> Marine seismic and [[magnetometer]] surveys starting in 1957 showed the extent of the atoll offshore and led to the first offshore well, Isla de Lobos No. 1-B, in 1963.<ref name="Viniegra O. p. 312"/> The depths of wells are on the order of 500 m onshore and 2000 m offshore.<ref>Viniegra O., L., and Castillo-Tejero, C.,Golden Lane Fields, Veracruz, Mexico, in Geology of Giant Petroleum Fields, Tulsa: American Association of Petroleum Geologists, Memoir 14, pp. 311-312, 1970.</ref>
