发明名称 METHOD AND COMPOSITION TO PREVENT FLUID MIXING IN PIPE
摘要 The present invention is related in general to fluid compositions and methods for servicing subterranean wells. Particularly, the invention relates to the use of a fiber-laden fluid to separate two wellbore-service fluids as they travel through a tubular body, preventing their commingling. The invention obviates the need for mechanical devices such as wiper plugs, or special adjustment of the wellbore-service fluids' rheological properties.
