    Lost circulation continues to be a very significant cost in many regions of the world. Many millions of dollars and much rig-time are lost fighting lost circulation and the resulting consequences. The highest costs are to be found when lost circulation occurs in reservoir sections and inappropriate, formation damaging, lost circulation materials are committed to the wellbore causing production impairment.

    The particle size used as loss of circulation material comprises two values (2 – 44 and 44 – 106 μ m) of calcium carbonate (CaCO 3), glass microspheres (180 – 300 μ m), and plastic particles (250 – 420 μ m). The efficiency of the fluid-LCM combination in combating lost circulation is evaluated based on the filtrate volume, thickness, dry and wet cake masses, and filtrate flow curves.
