Extend field life and improve recovery

In mature wells, conventional techniques for reducing produced water can be costly and time-consuming.

Run on standard electric wireline, our patented technology will precisely place an annular seal in a single run to stop or reduce water production.  

 

Tailored to each application, our epoxy solution will not segregate, nor slump, making it applicable even for horizontal wells.

Applications
Prevent or restrict water production in an un-cemented liner

Requirement: Isolate the annular space between the un-cemented liner and the formation to shut-off unwanted water intrusion.

Action: Inject a high viscous sealant into the open hole, to isolate the annulus.  After the tool is retrieved to the surface, a conventional bridge plug is run and placed inside the tubing to isolate production from the water reservoir below.  The plug can be installed anywhere outside of the liner or casing.

Separate the oil production zone in an open or gravel-packed annulus

Requirement: Restrict water production in an oil-producing well with sands screens, with or without gravel.

Action: Set a single plug to seal the lower section of the well by injecting a high viscous sealant into the gravel matrix, which will isolate the annulus and stop water production.  After the tool is retrieved to the surface, a conventional bridge plug is run and placed inside the tubing.  The epoxy viscosity will be tailored to individual annulus conditions in relation to open voids, natural sand presence or the extent of gravel within the annulus.

Prevent or restrict water in a screen completed well

Requirement: Isolate the annular space between the sand screens and the formation to shut-off unwanted water intrusion.

Action: Inject a high viscous sealant into the open hole to isolate the annulus between the screen section.   After the tool is retrieved to the surface, a conventional bridge plug is run and placed inside the joint or screen-coupling to isolate production from the water reservoir below.
