  • What is a cross-linkable polymer (LCM)?
  • The cross-linkable polymers among various loss circulation materials (LCM) are considered an efficient plugging material that can seal wide range of fracture sizes, strengthen the wellbore and provide solution for lost circulations under extreme drilling conditions.
  • 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
  • What is LCM in drilling mud?
  • LCMs are regu-larly introduced to the drilling mud system or spotted as a concentrated LCM pill to seal naturally existing fractures or induced fractures caused by drilling (Alkinani 2017). Depending on the loss rate (measured as bbl/hr), loss circulation has been classified as partial losses, seepage losses, or no returns.
  • Can hydrolyzed polyacrylamide be used as a loss prevention and sealing agent?
  • For example, Hashmat et al. (2016) investigated the interaction of commercial-grade hydrolyzed polyacrylamide (HPAM) and an HPAM derivative with polyethyleneimine (PEI) for the potential application of these polymeric systems as loss prevention and sealing agent.
