  • 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 a polymer cure lost circulation?
  • To cure lost circulation, Lecolier et al. (2005) designed a novel type of polymer-based substance. It was a nanocomposite organic/ inorganic gel with high gel strength, with the goal of plug-ging layers of high permeability. The nanocomposite gel can be injected into naturally fractured strata to fill cracks of varying widths.
  • 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.
