  • 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 eficiency 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.
  • Why do LCMS fail to regain drilling fluid circulation?
  • However, in many cases LCMs fail to regain drilling fluid circulation due to extreme downhole conditions and high severity of the loss. Therefore, multiple trials of LCM pills or cement plug maybe required in order to continue drilling. Proactive treatment is highly recommended to avoid such cases.
