ABSTRACT:
An apparatus and method for drawing down a fluid level in a wellbore which has a first tubular disposed within the wellbore so that a wellbore annulus is formed. The apparatus further includes an annular nozzle operatively attached to the first tubular, and wherein the annular nozzle comprises: an annular adapter; and, a suction tube that extends from the annular member into an inner portion of the first tubular. The apparatus further comprises a second tubular concentrically disposed within the first tubular so that a micro annulus is formed therein. The apparatus may further contain a jetting device for delivering an injected medium injected from the micro annulus into the wellbore annulus, and a stabilizer that stabilizes the second tubular within the first tubular.
