Abstract
There is disclosed a method for cleaning out of a well in which a compressed inert gas, produced by the non-cryogenic separation of air is delivered to the region of the well where particulate matter has collected that inhibits the ability of the well to produce.
Claims13
A well servicing system comprising:
- a membrane separator for separating at least a substantial portion of oxygen contained within a fluid feed stream to produce a substantially inert gas and a fluid byproduct;
- a compressor to increase the pressure of the substantially inert gas and to supply the substantially inert gas to a wellbore;
- and
- a collector to collect constituents comprising a fluid returning from the wellbore.
