A method includes conveying a wellbore isolation device into a wellbore, the wellbore isolation device including a primary valve arranged within a central flow passage. A fluid is then circulated through the central flow passage and into a tubing attached to a downhole end of the wellbore isolation device and in fluid communication with the central flow passage. The primary valve is moved from a first position to a second position and thereby diverts the fluid into an annulus defined between the wellbore and the wellbore isolation device. The primary valve may then be moved to seal the central flow passage and thereby prevent the fluid from flowing into the annulus or into the tubing.

A secondary barrier for use in conjunction with an isolation device in a portion of a non-vertical wellbore comprises: a swellable material, wherein the swellable material: (A) has dimensions such that, prior to swelling, the secondary barrier is capable of being placed into the portion of the non-vertical wellbore, and (B) fills a void within the portion of the non-vertical wellbore, wherein the swellable material fills the void after the swelling of at least a portion of the swellable material has occurred, wherein the secondary barrier is positioned adjacent to the isolation device in the portion of the non-vertical wellbore. A method of creating a secondary barrier comprises: introducing the secondary barrier into the portion of the non-vertical wellbore; and contacting or allowing the swellable material to come in contact with the swelling fluid or the increase in temperature.

A downhole tool for use in a well. A pumpable plug is used to urge bottom hole assemblies to a desired location in a well. The pumpable plug has a diameter greater than the maximum outer diameter of the casing in which the bottom hole assembly is to be located.

Downhole tool with pumpable section

A downhole tool for use in a well. The tool has a packer assembly and a pumpable plug associated with the packer assembly. The pumpable plug has a diameter greater than the maximum outer diameter of the packer assembly. The pumpable plug may be pumped through a casing having a diameter larger than that for which the packer assembly is designed and will urge the packer assembly through the large diameter casing into a smaller diameter casing for which the packer assembly is designed.
