Zusammenfassung:	A method for preventing loss of drilling fluid (14) into fractures (2) in the rock formation being drilled into fractures (2) in the rock formation being drilled includes using coconut coir (16) as a lost circulation material. Additionally, a mixture for reducing drilling fluid loss includes drilling fluid (14) and coconut coir (16). Other lost circulation materials can also be used. La présente invention concerne un procédé permettant d'empêcher la perte de fluide de forage dans des fractures de formation rocheuse forée, qui consiste à utiliser de la fibre de coco comme colmatant. Par ailleurs, un mélange efficace pour réduire la perte de fluide de forage comprend le fluide de forage et la fibre de coco. On peut aussi ajouter d'autres colmatants.
