Lost Circulation Material (Blended LCM) is a high-temperature softening and coarsely-ground modified hydrocarbon for loss-of-circulation material. These are used in oil-base mud systems. These are also water-insoluble, ultra-fine, complexed cellulose materials which are suitable for managing seepage and loss of circulation while drilling through consumed or under-pressured zones.
Lost Circulation Materials (LCMs) are used to seal zones where total loss, seepage or partial returns are experienced. LCM products work by sealing and plugging loss zones, by bridging and plugging off voids or by forming a matrix within the wall cake to create an impermeable filter cake. LCMs will improved borehole stability and deliver significant mud cost savings. |
