  • What is lost circulation material (LCM)?
  • Lost circulation material (LCM) is used to treat the loss that occurs or proactively strengthen the wellbore of the potential loss zones. The polyacrylamide (PAM)/Polyethylenimine (PEI) cross-linkable polymer gel is proven to work best in zone-sealing and plugging applications.
  • What is lost circulation material?
  • The problem of lost circulation is a direct consequence of the presence of fractures or high permeability. Lost circulation material (LCM) is used to treat the loss that occurs or proactively strengthen the wellbore of the potential loss zones.
  • Can crosslinked polymer be used as a loss circulation material?
  • In the same way, using of crosslinked polymer as loss circulation materials provides better sealing efficiency over wide range of temperatures. The material can be circulated with the mud as a flowing gel to prevent loss circulation or injected as a pill to plug thief zones and stop severe loss. 2.5. Formation damage caused by LCMs
  • Can polymeric solutions be used to treat loss circulation?
  • However, the unique rheological properties and high thermal stability of the polymeric solutions have boosted the potentiality of using them to treat loss circulation in natural fractured formation or high permeable zones since it is classified as one of the types of conformance problems.
