The only annulus solution available for setting an annular plug in a single run
renegade services has sought out and partnered with NorwegiAn based, oil-field technology company, CannSealTM
CannSealTM is a new and proven solution for repairing micro-annulus in producing and non-producing wells, combating water production, plugging leaking packers and re-establishing degridated well barriers. The intervention is preformed using e-line making the production interruption notably short and cost effective.
Having traveled to Norway to train with the innovative CannSealTM team, Renegade engineers and technicians have mastered the functions of CannSealTM operations. Renegade is also the exclusive US servic provier for the technology.
Proven Technology: CannSealTM has been tested in lab, on surface and in deepwater
Major oil companies operating mature wells in the North Sea saw 10-20% increased oil recovery totaling ~200,000 otherwise unrecovered barrels per year per well pair when CannSealTM was used to repair the thief zones and cracks in the flood lines. Further research showed that the impact these mature wells had the potential to reach $200MM.
The tool underwent more than 100 hours of systematic condition replication trials in the testing facility at the CannSealTM HQ in Stavanger, Norway. The testing included both horizontal and vertical (40 meters deep) pressure and temperature (P&T) analysis in conditions that mimic and exceed the potential. Above succeeding all lab trials, the system has also passed the Altus Well Academy which is required to prove compatibility with the Altus tractor technology. Emergency release of the tool with subsequent successful fishing.
HOW IT WORKS
- The problem section of the casing, liner, screen, packer, or column is located.
- The tool is inserted into the well using eline and is navigated to the questionable section.
- The anchors are set, stoke up, perforation is initiated, stoke down.
- Pads are aligned and the customized epoxy sealant is injected into the perforation.
- CannSealTM is then either moved to the next repair/isolation location or removed.

AREAs OF USE
Injected resin into the cement matrix to prevent/restrict water production.
CannSealTM improves isolation using high viscous epoxy sealant in combination with a low viscosity epoxy sealant dependent on the expected quality of the cement
High viscous sealant injected into open hole annulus isolates the annulus and stops water production.
The plug can be set anywhere, externally of the tubing/liner.
SAND SCREEN WITH OR WITHOUT GRAVEL
Sealant is used in zonal isolation of annulus in a gravel matrix to stop water production.
After the tool is retrieved to surface, a conventional bridge plug will be placed inside the tubing/pipe to isolate production from the water reservoir below.
LEAKING PACKER PLUG
DUAL PLUG AS A BARRIER OR REPAIRING A LEAKING PACKER
High density, low viscosity (HdLv) sealant is injected on top of foundation, or if the production packers leak, the sealant will be placed on top of the packer.
An individual remedial plug can be installed anywhere in the annulus above the leaking packer using a foundation made from a regular CannSeal high viscous sealant foundation.
SUSTAINED CASING PRESSURE (SCP)
MITIGATING SUSTAINED CASING PRESSURE IN CEMENTED ANNULUS
Using the CannSeal injection unit with multiple injection points, a tailor-made epoxy/substance will be injected through the tool into the micro-annulus.
The rheology of the sealant can be adjusted depending on the cement quality.
The sealant can be injected at high differential pressure into the cement matrix.
PLUG FOUNDATION FOR CIRCULATION IN A COLUMN
The CannSeal epoxy sealant can be carefully designed to be placed inside open or partly open annulus. Ultra high viscosity properties will allow the plug to be placed in any angle, not being subject to segregation before being solidified.
After placement, the plug can withstand high dynamic forces while circulating in the cement.
CanSealTM is a great solution for regulatory departments because it repairs micro annulus and sustained casing pressure. Pennsylvania DEP and Colorado’s Oil & Gas Commission, to name a few, advocate the importance of eliminating this type of issue by finding a means to mitigate stray gas migration from the beginning.
