RE: RE: RE: kooteniYour comment:
but if the fluid level is 9000 feet underground, just how is the oil getting out of the well?
You see, Mr. Expert, that backpressure will always be there as that 9000-ft column of oil above the pump will always be there, exerting a backpressure on the pump. So much for your "explanation".
Your comment on pumps shows your total ignorance of oil well pumping systems. I suggest you google "Oilwell
pumping systems"
Pumps are placed as close as possible to the perforations. The purpose of this is to lower the annular fluid level
to the lowest possible level resulting in the lowest bottom hole pressure. Then a simple law of reservoir engineering
dictates that the rate of flow through the formation is a function of the differential pressure. With the pressure differential
drop of 2600 psi in the example I gave you you would get a significant increase in flow into the wellbore. As long as
the pump equipment is large enough to remove all the fluid that enters the wellbore the fluid level will stay at the bottom
hole pump.
You mention formation porosity on 3-4. I believe we were discussing 15-36 which is 6 miles away from 3-4. You cannot
logically claim that porosity's are the same. Still the most important factor is permeability which dictate how fast you recover the oil. The faster you recover the oil the better the economics.
Suggest you refrain from posting your lack of knowledge as you are making a fool of yourself.
