How far above the perforations are ESP's tyrpical set in an oil well?
141910
There is no 'set' distance above wellbore perforations for a Submersible Pump to be installed.  The distance varies with the diameter of the wellbore, the capacity of the pump, and the 'natural' temperature of the wellbore fluids.\n\nSpacing between perforations and the pump array itself is crucial ONLY to prevent premature pump failure due to overheating.\n\nThe manufacturer of your ESP should provide tables to assist you in calculating the proper placement.

How big a hole do you propose to drill?\nDo you want to be operating the rig when it hits magma?

If it is specifically mentioned that it is a thin pipe (ratio of internal diameter to wall thickness greater than 20:1) then you can safely neglect the radial stress i.e. its value is zero. To find the longitudinal stress, you have to consider the end conditions and to find the tangential stress you have to use the equation for thin pressure vessel.\n\nTo be specific, according to your question, you can take the radial stress equal to 0.\n\n\n\nTo oil field trash:\nYou have stated the equation for tangential or circumferential stress not that for radial stress.\n\n\nTo Chris H:\nWhy do you mislead others? How dare you tell me I am wrong? In support of my statement I am furnishing the link to a note on Thin Cylinders below. Click on it and see how much ignorant you are about this topic. I have successfully completed a year-long project on Pressure Vessel Design. Before saying that someone is wrong, look carefully at his answer. I wrote "you can safely neglect the radial stress" not "the radial stress is always zero". In thin cylinders, only the membrane stresses are considered giving fairly accurate results. \nThe starting point in derivation of the equation \n(S1)/(r1) + (S2)/(r2) = p/t \nis to assume that the radial stress is zero and the hoop stress 'S1' and meridional stress 'S2' doesn't vary along the thickness. \nHere 'R1' and 'R2' are radii of curvature in the circumferential and meridional planes, respectively, 'p' is the internal pressure and 't' is the wall thickness. \nYou may give a wrong answer to a question because you may be ignorant of its correct answer. That is alright. But when you challenge some answer be more careful in future, in Yahoo Answers as well as in your daily life.

not that deep... There really is not that much moisture up there.  I would probably say 1-2 feet

Depends what medium is eroding it.\nI think you're looking for the hardness scale.

The deepest research borehole ever drilled was in Russia, on the Kola peninsula. Over a period of more than a decade a huge purpose-built rig drilled to over 12 kilometres to investigate the structure of the Continental Crust (sorry about the units, I'm in Australia and we're metric here - so are the Russians). \n\nThe results showed unexpected fractures and fissures and water-bearing zones deep in the crust, where conventional wisdom expected the pressure of rock above to close up all cracks. \n\nThe deepest oil wells that I know are drilled to about 6km, say 20,000ft. Most normal oil wells are drilled to about 3000 to 5000 metres -10,000 to 16,000 ft.

At least 12 feet.\nI could be wrong though.

The term penetrating in this application means the ability of the oil to get between very small gaps. If there were any small gaps in the tin the oil would indeed leak from the container

A sealed (pessurised) system is normally about 1.5 bar. Open vented - depends on the head, 10 meters/ 33'  = 1bar

It depends on the temperature of the fluid:\n-20°F to 100°F Max non shock pressure rating is 2160 psig\nat 850°F Max non-shock pressure rating is 900 psig

depends on the hydrosataic pressure of the aquifer relative to the elivation or the water bearing strata

We drill holes and pump the oil out. The best wells then inject something in the oils place to keep the ground from sinking and maximize the oil you can get. The cost varies greatly depending where and how deep the oil is. If it is 200 feet down in your backyard, not too much. If it is in the Bearing Sea, a ton.
