Abstract:
A drilling assembly is tripped in a cased hole to make more open hole. The assembly features retracted scrapers and a closed circulation sub so that the drilling can commence with string pressure delivered to bit nozzles due to the circulation sub being in a closed position. When drilling is done and the bit is to be removed, an object lands on a seat on a sleeve that acts as a piston to break scraper retainers for casing scraping deployment and to open the circulation port. A bypass opens around the seated ball when the sleeve shifts to allow flow around the seated ball for circulation while scraping. Drilling and casing scraping are accomplished in a single trip.

Claim (Index 17):
The method of  claim 16 , comprising:\n providing a third sleeve having a third seat thereon; providing as said at least one object a first and a second objects; locating said second object on said third seat in said third sleeve to close said at least one port after opening said at least one port with said second sleeve.
