I have an interview tomorrow and they are going to ask me about the oil and gas industry. A brief overview of the extraction process of crude oil, and other process's involved (namely on offshore locations) would be greatly appreciated.
The job is for an apprentice mechanical techinician.

Check my brief explanation in one of your previous questionsOil Extraction?
oil is produced from platform or subsea wells. The effluent (oil, gas %26amp; water) flows through a ';christmas tree'; which has many valves fitted to it, the main ones are the downhole safety valve, master valve and wing valve. From here the effluent is routed to either a test or production separator. Inside the vessel there is a deflector dish to help separation by changing the pressure and direction of the effluent. Straightening vanes, mist pads, and coalescing pads help dry and direct the gas. Most importantly there is a weir. The oil sits on top of the water and spills over the weir under level control. The gas is then dried and compressed, the oil is routed to the storage vessels or cells. The water is sent overboard or back into reservoir. Two separators can be used in series to aid the separation. It is a lot more complicated than this with lots more info but its a start as the whole thing is a too long to write here. Hope this helps, good luck
