1. A bottom hole assembly adapted for connection to a tubing string, the bottom hole assembly comprising:
(a) a by-pass valve assembly comprising an up-hole end adapted for fluid communication with fluid flowing in a tubing string, a downhole end and a first flow passage extending between the up-hole end and the downhole end of the by-pass assembly, and further comprising at least one port for fluid communication between the first flow passage and an annular area exterior of the bottom hole assembly;
(b) a resettable sealing assembly positioned downhole of the by-pass valve assembly and comprising an up-hole end, a downhole end and a second flow passage there between; and
(c) a shifting tool assembly positioned downhole of the resettable sealing assembly and comprising an up-hole end, a downhole end and a third flow passage there between;, wherein the by-pass valve assembly is operable to direct fluid flow in a first mode of operation and a second mode of operation;, wherein in said first mode of operation fluid flow is directed from the first flow passage to the annular area exterior of the bottom hole assembly through the port and is not directed from the first flow passage to the second flow passage in the resettable sealing assembly; and, wherein in said second mode of operation fluid flow is prevented from flowing from the first flow passage to the annular area exterior of the bottom hole assembly through the port and is directed from the first flow passage to the second flow passage in the resettable sealing assembly.
