The well casing having a first fluid column therein with an upper end positioned above the perforation zone. Also described is a sliding plug seal structure interposable between facing end portions of first and second cylindrical fluid sections, disposed in a pipe having an inside diameter, to prevent significant intermixing between the facing end portions when the first and second cylindrical fluid sections are driven axially along the interior of the pipe.
