Overview

Overview

Block fluid or gas movement between the casing and annulus with the ISOZONE™ external casing packer (ECP) from Baker Hughes.

 

Improve your cement jobs with proven isolation solutions

A primary cementing and zone isolation packer, the ISOZONE ECP is deployed as an integral part of your casing string to provide a reliable seal between the casing and the wellbore. The ECP’s inflatable element is expanded by pumping cement or another fluid down the casing and is compatible with ongoing cementing operations.

For zonal isolation, the ECP seals the wellbore between zones in your completions—both cemented and uncemented. The packer includes a patented top-mounted valve collar that senses true annulus pressure for consistent, accurate inflation. The packer inflates progressively from bottom to top, which eliminates trapped fluid in the annulus to allow complete inflation.

As a cement packer, the ISOZONE ECP protects the cement from challenging damage by blocking movement of gas or fluid and allowing the cement to set undisturbed. A set of four independently manifolded valves helps ensure even inflation when pumping cement. The ECP isolates and protects sensitive formations from the cement. And for your deep wells, the ECP allows for stage cementing to protect the lower zones from a long column of cement. 

The ISOZONE ECP is available in 7-ft and 10-ft (2.1-m to 3.0-m) element lengths. A patented rough-coated mandrel prevents element damage during pipe movement, either reciprocation or rotation.

The ECP is available for most casing sizes, weights, grades, thread connections, and materials. Work with our application specialists to select the ISOZONE ECP with the optimal packing element expansion capabilities and pressure ratings for your application.
