ROP Accelerators in Drilling Fluids: Recent Progress

This paper discussed the progresses made on ROP accelerators(or enhancers) overseas and the mechanism of action of the ROP accelerators.The ROP accelerators helped increase the rate of penetration by improving the lubricity and reducing the viscosity of the mud which in turn reduced the friction of drill pipes on the wall of the hole.By forming a thin film around the drill bit,drill assembly,thus preventing the balling of the drill bit and drill pipe,the ROP accelerators rendered the mud lubricity and increased the ROP.
