Below, you get more insight into this case. You may also download your free copy of the case study, which also includes details about how Wellcem implemented the solution and most importantly - the results achieved for the operator company.

The Challenge

  • Collapsed/parted tubing and production casing
  • Lower reservoir pressure than the hydrostatic pressure of sea water – well on vacuum.
  • Plugging of reservoir interval in rig-less intervention
  • Keeping top of plug at a taggable depth. i.e. above parted tubing.

The customers' options

  • Cement
  • Resins

Why did they choose to cooperate with Wellcem?

Due to a collasped tubular using cement to isolate this well was not a good option. Using cement would run the risk of bridging off and not being to pump the desired volume below the collasped area. Wellcem Resin System gave the ability to pump below the collasped area, setting a plug to fully isolate the in the well.
