摘要:
Lost circulation materials may include pluralities of ceramic spheres having a size distribution in a range of from about 5 mm to about 25 mm and such that the lost circulation materials are porous and permeable. Methods of eliminating or reducing lost circulation from a well having a loss zone may include introducing the porous and permeable lost circulation materials into the well such that a porous and permeable flow barrier is created in the loss zone, wherein the porous and permeable flow barrier may prevent whole mud loss while drilling and allows hydrocarbon production after completion of the well. Carrier fluids may include water, viscosifiers, fluid loss additives, weighting agents, lost circulation materials containing pluralities of ceramic spheres having a size distribution in a range of from about 5 mm to about 25 mm.
