OS ROP XL - Drilling ROP Enhancer




Drilling fluid systems and additives have an enormous effect on rates of penetration, ROPs.

Shale drilling represents one of the biggest challenges for water based fluids and inhibition, cuttings control and bit/BHA management are fundamental to maximizing ROP.

Inhibition is the first line of defense when drilling shales but the subsequent management of the cuttings and maintaining a clean bit/BHA are often ignored resulting in poor ROPs and much trouble time.


OS ROP used with OS ROP COAT and OS ROP XL will triple lock maximum ROPs when shale drilling.


Product Information 

OS ROP XL is a specially formulated blend of synthetics and surface active agents, designed to reduce the problem of drill solids agglomeration at the bit and BHA, while also providing a degree of lubrication to the drilling fluid.  Drill solids can often accrete to make hard agglomerations, causing difficulties for the drilling operations. This product is designed to give the normal surface tension reductions of a detergent, and at the same time prevent agglomeration of solids, minimising the potential for bit and BHA balling.


Typical Physical Properties 

Appearance   -   Yellow Liquid                                   

S.G. @ 20oC   -   0.75 – 1.00

Viscosity @ 20oC   -   Less than 50 Cps                         

Flash Point (PMCC)   -   Greater than 150oF

Pour Point   -   Less than 0oC



OS ROP XL is a concentrated liquid additive which mixes easily into the mud and is very effective in low dosages.



The required dosage of OS ROP XL is 0.3 gallons per barrel and increase the dose if bit balling is still a problem. 



OS ROP XL is packaged in 55 US gallon drums.
