One of the most challenging issues during drilling operations is lost circulation, which can
cause several problems that could lead to increasing the non-productive time (NPT) and …

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 …

Excessive water production from natural gas reservoirs is a main challenge facing the
industry nowadays. Polymeric gelants have been widely applied to seal the water …

Geothermal formations often contain extensive fracture networks. These fracture networks
contribute to the significant loss of drilling fluids during geothermal drilling. Multiple loss …

Lost circulation is one of the great challenges during the drilling process as it can not only
increase the risk of drilling operations but also cause an increase in drilling costs, thus …

Loss circulation materials in the last two decades have witnessed a lot of developments and
implementations. New technologies and materials are introduced to treat various types of …

Drilling fluid and filtrates invasion often alter the near-wellbore flow properties during
overbalanced drilling. The utilization of polymeric gels to prevent drilling fluid loss reduces …

Minimization of water output is key to prolong oil field production. Although hydrogels are an
effective alternative to sealing preferable water pathways in highly permeable reservoirs …

The traditional way to mitigate loss circulation in drilling operations is to use preventative
and curative materials. However, it is difficult to quantify the amount of materials from every …

Loss circulation is frequent while drilling in naturally fractured or depleted reservoirs, which
is usually associated with high non-productive time (NPT). Moreover, naturally pre-existing …
