Multitask Wellbore Filter
Clean and filter wells in one trip
The Sharp Razor multitask wellbore filter allows brushing of debris from the wellbore wall, filtering the fluid, and recovering debris, all in one trip. This tool can be run in conjunction with other Sharp Razor wellbore cleanup tools to perform displacement and wellbore cleanup operations.
The filter is usually used during the precompletion stage, but it can be run any time the wellbore is contaminated with debris. It is commonly used as a key point indicator to verify cleanliness of the wellbore.
When run in hole, the tool acts as a boot basket, collecting large debris when fluids pass through the filter. When pulled out of hole, the bypass is closed and the tool diverts fluid through the filter media capturing the debris; once at surface, the debris can be conveniently removed at rig floor and the tool is ready to be immediately returned downhole. A large quantity of debris recovered indicates that another trip is needed to more thoroughly clean the wellbore.
