Offshore drilling began in 1897, simply 38 years after Col. Edwin Drake drilled the initially well in 1859. H.L. Williams is credited with drilling a well off a wood pier in the Santa Barbara Channel in California. He used the pier to support a land rig next to an existing field. By 1921, steel piers were being utilized in Rincon and Elwood(California)to support land-type drilling rigs.

In 1932, a steel-pier island( 60 90 feet with a 25-ft air space )was built mile offshore by a little oil business, Indian Petroleum Corp., to support another onshore-type rig. Although the wells were frustrating and the island was damaged in 1940 by a storm, it was the forerunner of the steel-jacketed platforms these days. Subsequently, a 9,000-ft well was drilled in 1941 in fashion similar to the California wells by usage of a wooden pier. With the start of World War II, nevertheless, all offshore drilling activities halted. After Try This of World War II, the state of Louisiana held an overseas state waters lease sale in 1945. Prior to the latter act, core drilling might be done only till a program of oil and gas. At that time, all drilling had to stop and the core hole plugged with cement. The first on-water drilling The very first" on-water drilling"was born in the swamps of Louisiana in the early 1930s with the use of shallow-draft barges. Canals were, and still are, dug up so that tugs can set in motion the barges to areas. Later, barges were"published"on a lattice steel structure above the barge, enabling them to work in much deeper water depths by immersing the barge on the bay bottoms. These barges typically needed pilings around them to keep them from being moved off area by winds and waves. The system, which was a conversion from an inland drilling barge, had two stability pontoons, one on each side of the barge, that hydraulically boosted and down as the barge was submerged and pumped out. These pontoons offered the essential stability for this operation. The Breton Rig 20, later referred to as the Transworld Rig 40, was a significant advance due to the fact that it removed the expense
