An essential part of an automated MPD control system is the hydraulic model, which in many cases is the limiting factor for achievable accuracy of the system. A lot of effort has therefore been put into developing advanced hydraulic models that capture all aspects of the drilling fluid hydraulics. However, a main drawback is the resulting complexity of these models, which require expert knowled...

O n 20 April 2010, the BP-owned, Transoceanoperated Deepwater Horizon oil-drilling rig exploded, killing 11 workers and injuring 17, and sending massive quantities of crude oil riddled with lethal toxins from the sea floor into the Gulf of Mexico. Geophysicists, Earth-space scientists, and policymakers continue to debate the cause of the explosion, how much oil has been released, how best to co...

Sequestration Program is developing a technology portfolio of safe, cost-effective, commercial-scale carbon dioxide (CO 2) capture, storage, and mitigation technologies that will be available for commercial deployment beginning in 2020. The updated website can be viewed at: County, Wyoming, in late April. The $16.9 million Phase I project, co-sponsored by DOE's Office of Fossil Energy (FE), is ...

On 20 April the offshore oil-drilling rig known as Deepwater Horizon was completing the finishing touches on its latest well in the Gulf of Mexico when it suffered an explosion on board, resulting in the death of 11 and injury of several others. The rig then sunk approximately a mile to the ocean floor, where it remains. The loss of life in the incident was only the beginning of what is now a m...

Considerable amount of Oil and Gas (O&G) production and process installations operating in the North Sea are getting aged and requiring continuous modifications. Nature of such contractual jobs is relatively short term with demanding deliverables. Hence, the engineering contractors require excellent coordination and seamless communication during all phases of a project. For any contractor/suppl...

The article is devoted to the analysis of energy consumption in process drilling wells karst rock blocks. paper presents results experimental and analytical studies for destruction massifs with a complex structure characterized by presence cavities. operation machine during block was monitored. In article, use criterion intensity well proposed assess level rig. On basis conducted research, depe...

There is a law . In fact, there are three laws that, jointly and severally, should have anticipated and provided measures to prevent and cope with the explosion of the drilling rig Deepwater Horizon . Instead, we have 11 deaths, 17 serious injuries, the release of an American record 2 .6 million gallons of oil,2 an equivalent record for chemical dispersants,3 months of Mutt ‘n’ Jeff responses, ...

Power head is the main motive mechanism of rotary drilling rig. High axial pressure and high frequency is one of its typical working conditions. Axial loading test is a key point in power head performance tests. Overall design, system theoretical analysis and simulation of power head axial loading system were carried out. The bond graph model and state equations of power head axial servo loadin...
