Abstract
A method of drawing a fluid into a wellbore from a formation. The wellbore is separated into a first section and a second section via an annulus closure device, the annulus closure device having a passage therethrough. A pump at a surface location, circulates a circulation fluid in the first section to reduce a pressure in the second section. Reducing the pressure in the second section draws the fluid from the formation into the second section.
