... Abstract Whilst drilling the 12 ½" and 8 ½" sections on a HPHT field in the North Sea, fluid losses were encountered which required the pumping of high concentration Loss Circulation Material (LCM) as well as multiple ‘through the bit’ cement squeezes. The reservoir had been under production...

... conducted to explore the effects of LCM implementation strategies in lost circulation remediation and formation damage control. Different combinations of granular and fibrous LCMs were tested in a permeability plugging apparatus with slotted discs. When LCM particles accumulated at the slots and formed...

... Abstract Lost circulation is commonly recognized as one of major drilling complications that cause low efficiency and a high cost in oil or gas well drilling. The current practice of mitigating lost circulation with lost circulation materials (LCM) is still empirical due to the lack...

... particulate lost circulation materials (LCMs), such as acid-soluble ground marble, might not effectively cure severe losses. Furthermore, because the application is in a producing formation, avoiding reservoir damage is a major criterion that any potential solution should satisfy. The "band-width...
