Abstract:

A system and method for treating a portion of a wellbore that includes a bottom hole assembly (BHA) connected to a work string. The BHA includes a packing element movable between an unset position and a set position and a locator device movable between retracted position and expanded positions. The locator device may be a locator collet. The locator collet may be expanded by a cone movable with respect to the collet. The expanded locator device is configured to engage a profile in a ported tubular within the wellbore. The engagement between the locator device and the profile selectively prevents further movement of the BHA and provides an indication of the location the BHA. The packing element may then be actuated and the wellbore treated through a port in the ported tubular. The BHA may then be moved to a different ported housing to treat another portion of the wellbore.

Abstract:

A method and system of treating a horizontal wellbore having multiple production zones. A bottom hole assembly connected to coiled tubing is positioned within the horizontal wellbore. The friction between the casing of the horizontal wellbore and bottom hole assembly and coiled tubing may prevent the bottom hole assembly from traversing the entire length of the horizontal wellbore. After treating a zone within the wellbore, a flush fluid with a lubricant may be pumped down the annulus between the coiled tubing and the casing. The lubricant may reduce the coefficient of friction between the casing and the coiled tubing permitting the bottom hole assembly to travel farther into the horizontal wellbore. The bottom hole assembly may include a vibratory device that may be actuated to reduce the coefficient of friction between the casing and the coiled tubing permitting the bottom hole assembly to travel farther into the horizontal wellbore.
