Deepwater Horizon was an ultra-deepwater, dynamically positioned, semi-submersible offshore drilling rig owned by Transocean and operated by the BP company. On 20 April 2010, while drilling in the Gulf of Mexico at the Macondo Prospect, a blowout caused an explosion on the rig that killed 11 crewmen and ignited a fireball visible from 40 miles (64 km) away. The fire was inextinguisha. DesignDeepwater Horizon was a fifth-generation, RBS-8D design (i.e. model type), deepwater, , column-stabilized, semi-submersible , designed to drill wells for oil explorati. .
Deepwater Horizon was built for R&B Falcon (which later became part of ) by in , South Korea. Construction started in December 1998, the was laid on 21 March 200.
[pdf] A common drill rig used for "Shot Hole Drilling" is the L.I.S (Low Impact Seismic) mounted on track carrier for operation in cut lines or environmentally sensitive area. Truck mounted drill or 4X4 buggy are utilized in the prairies. These drill rigs use water or air to assist the drilling.
[pdf] Directional drilling (or slant drilling) is the practice of drilling non-vertical bores. It can be broken down into four main groups: oilfield directional drilling, utility installation directional drilling, directional boring (horizontal directional drilling - HDD), and surface in seam (SIS), which horizontally intersects a vertical bore target to extract coal bed methane.. HistoryMany prerequisites enabled this suite of technologies to become productive. Probably, the first requirement was the realization that , or , do not necessarily need to be vertical. This realization. .
Wells are drilled directionally for several purposes: • Increasing the exposed section length through the reservoir by drilling through the reservoir at an angle.• Drilling into the reservoir w.
