Abstract:
Friction forces pose a danger to wellbore formation integrity, equipment stress, and success of the drilling operation. Friction forces in the wellbore can be managed by adding lubricants into drilling fluids. Lubricants reduce torque and drag friction forces on the drillstring, and improve the rate of penetration (ROP) during operation of the wellbore. Polyalkylene glycol lubricant with structure R—(OCH 2 CH 2 ) m —(OCH(CH 3 )CH 2 ) n —OH can be used for water-based drilling fluids. Polyalkylene glycol coats metal surfaces and creates a lubricating layer to reduce torque and drag. Adding polyalkylene glycol to high density water-based drilling fluids is an effective method for reducing frictional forces during HPHT and high salinity drilling applications.

Claim (Index 13):
The composition of  claim 9  wherein the water-based drilling fluid composition has a coefficient of friction that is decreased by up to 32% after addition of the polyethylene glycol.
