Temporary Gel Plug for Zonal Isolation

Page last modified

April 11 2024

Whether you require zonal isolation or a temporary blocking plug, AXI-Zone can help.

AXI-Zone's simplistic design enables you to maintain pressure control or achieve temporary isolation with ease. This is a pumpable gel that becomes rigid within the well, forming a tight and reliable plug.

It is delivered as two components - a base and a retarder. Both are easily mixed into water or brine using standard equipment, before being pumped into place either via coiled tubing or bullheading.

The retarder dosage can easily be adjusted to suit the delay in setting required.

Pros & Limitations

Cost saving, as it can be deployed without a rig

Deployed using simple mixing equipment and either coiled tubing or bullheading

Can be applied in temperatures up to 175C

Compatible in high salinity environments

Accomodates delays in deployment, as the setting is thermally controlled

Easily broken chemically and flowed back

The surface temperature must be lower than the well temperature
