First drilling rig factory

Peter Sweeny, building on Robert Beart's earlier design, made a huge advancement in rotary drill technology, enabling almost continuous drilling. His new design also improved on hole cleaning. . Charles Burleigh, John W. Brooks, and Stephen F. Gates patented a mechanical drill meant to be used on the Hoosac tunnel: the compressed air Burleigh drill. The tunnel spurred several innovations in drilling technology, including the earlier Couch/Fowle drill.. . Edward A.L. Roberts was awarded a patent in November 1866 for what would become known as the Roberts Torpedo, a device for increasing. Launched in 1954 and capable of drilling wells in water up to 40 feet in depth, Mr. Charlie was the world’s first mobile offshore drilling platform. It was designated a National Historic Landmark in December 2024. Photo courtesy Murphy Oil. [pdf]
