  • Can LCMS reduce lost circulation in oil based mud?
  • Nasiri A, Shahrabi MA, Moraveji MK (2018b) Application of new eco-friendly LCMs for combating the lost circulation in heavy-weight and oil-based mud. RSC advances 8 (18):9685–9696 Nayberg TM (1987) Laboratory study of lost circulation materials for use in both oil-based and water-based drilling muds.
  • What are lost circulation materials (LCMS)?
  • Paper presented at the SPE Western Regional Meeting, Garden Grove, California, USA, April 2018. Lost circulation materials (LCM's) have been widely used to avoid or stop losses. Due to a large number of currently available materials, treatments, and their different applications, classification of them is very important.
  • 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.
  • What are lost circulation materials?
  • Lost circulation materials are characterized as fibrous, flaky, granular, or a combination of the three. The LCM can be useful if the bridge it generates inside the fracture is strong enough to withstand all of the mechanical forces pushing on it (Cook et al. 2012 ).
