These platforms can take the form of either floating semisubmersible platforms or drill ships. The basic idea behind their design is that, once the well has been drilled, much of the production equipment can be mounted on the seafloor and the petroleum pumped to the surface facilities through flexible risers.. .
This platform is essentially a king-sized version of the Sea Star platform, except the tension legs extend from the ocean floor to the platform itself. It experiences more horizontal motion and a certain degree of vertical motion, but it allows oil companies to drill at. .
Finally, if you absolutely need to drill a hole at a depth of 10,000 feet (3,048 meters), then the spar platform is the oil rig for you. With this design, the drilling platform sits atop a giant, hollow cylindrical hull. The other end of the cylinder descends around. .
This approach takes the idea of mounting the wellhead on the seafloor and applies it to even greater depths — 7,000 feet (2,134 meters) or more. Once the well has been drilled by a. .
Deep-sea waters reach nearly freezing temperatures, contain pressures great enough to crack iron casings and are subject to rough, deep-sea currents. Engineers have to design equipment that can stand up to the pressure, while also preventing boiling oil.
[pdf] 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.. .

Until were developed in the late 19th century, the main method for drilling rock was muscle power of man or animal. The technique of oil drilling through or has its origins dating back to the ancient Chinese Han dynasty in 100 BC, where percussion drilling was used to extract natural gas in the Sichuan province. Early oil and gas drilli.
