Abstract

A method for facilitating a downhole cutting operation comprises providing a drilling fluid conditioning device in a surface portion of a tubular string providing mounting for a cutting tool on a downhole portion of the string. Initially, drilling fluid is circulated through the conditioning device and the tubular string to condition the drilling fluid. The drilling fluid conditioning device is then removed from the string and the conditioned drilling fluid circulated through the tubular string and the cutting tool.
