A system and method for removing particles from a well bore penetrating a possible hydrocarbon producing formation, according to which drilling fluid is mixed with a weighted material, and the mixture is introduced into a well bore so that the mixture scours any particles accumulated in the well bore. A well- completion fluid is introduced into the well bore that dissolves the weighted material.
L'invention concerne un système et un procédé destinés à éliminer des particules d'un forage pénétrant une formation potentiellement productrice d'hydrocarbures, ce procédé consistant à mélanger le fluide forage à un matériau de lest, et à introduire le mélange dans le forage de façon que ce mélange évacue les particules accumulées dans le forage. Un fluide de finition est introduit dans le forage afin de dissoudre le matériau de lest.
