Abstract
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.
Claims16
A method for removing particles from a well bore, comprising mixing drilling fluid with a weighted material, introducing the mixture into a well bore so that the mixture scours any particles accumulated in the well bore, and introducing a second fluid into the well bore that dissolves the weighted material.
A system for removing particles from a well bore, comprising a source of drilling fluid, means for mixing the drilling fluid with a weighted material, means for introducing the mixture into a well bore so that the mixture scours any particles accumulated in the well bore, and a source of a second fluid that, when introduced into the well bore, dissolves the weighted material.
