Ohio Offshore Wells

Oil was produced from platforms on Grand Lake St. Marys as early as early as 1887.

 

As the turn of the century approached, oil producing Ohio wells drilled far out over a reservoir mark the beginning of America’s offshore petroleum industry, according to Mercer County historians.

America’s first offshore drilling once was generally acknowledged to be over Louisiana’s Caddo Lake in 1911 – until researchers in Mercer and Auglaize counties in Ohio said otherwise.

Oil patch sleuths pointed to Mercer County documents recording wells producing oil above the waters of Grand Lake St. Marys at least 20 years before drillers ventured over the waters of Caddo Lake above the giant Caddo-Pine Island field. (more…)

Offshore Drilling History

Petroleum exploration and production technologies evolved from 1890s platforms on piers and lakes.

 

The U.S. offshore drilling for oil began in the late-19th century on lakes and at the ends of Pacific Ocean piers. Until an innovative Kerr-McGee drilling platform in 1947, no offshore drilling company had ever risked drilling beyond the sight of land.

In 1896, as enterprising businessmen pursued California’s prolific Summerland oilfield all the way to the beach, the lure of offshore production enticed Henry L. Williams and his associates to build a pier 300 feet out into the Pacific — and mount a standard cable-tool rig on it. (more…)
