Wellbore Specialties multi-use Jet-Set(patent pending) well cleaning system is an effective solution for wellbore clean out that can be used for either drilling, completion, or workover applications.
By seating a ball in a ported ball seat, a portion of fluid is restricted and redirected from the bit to WBS JetSet well cleaning jets, while still allowing the remaining portion of fluid out through the bit to lift and remove debris. The one way check on Jet-Set jetting valves provide well control from the annulus.
The jet's fan shaped fluid pattern provides maximum fluid coverage for cleaning the casing wall, liner tops, hard to reach areas in the blow out preventers, as well as the wear bushing profile when run in conjunction with a wear bushing pulling tool and waste catcher. The high pressure jetting is not only effective for cleaning and removing debris, it also helps keep the casing scrapers and brushes clean and operating at maximum performance.
When on bottom with the bit, standard displacement operations can be performed. Applications such as pumping spacers will not be jeopardized due to the short distance between the bit and the Wellbore Specialties Jet-Set Well Cleaning Tool. Ball reversal is not necessary for effective displacement results.
