... Abstract The drive to reduce freshwater consumption has led to a significant increase in the use of waste streams, such as high salinity produced water brines, as base fluids in drilling fluid systems. However, the performance of conventional lubricants is typically reduced in such brines...

...Introduction Abstract The use of lubricants is commonplace when drilling with water-based drilling fluids. They are less frequently applied when drilling with non-aqueous fluids, as the oil-based drilling fluid is thought to impart a high lubricity. With increased reach of the wells...

... Abstract Thread compounds play an important role in the sealing ability of casing connections in the oil and gas industry. Next to their lubricating role during assembly, most of these thread compounds make use of nonbiodegradable or persistent particle additives to aid in the sealing ability...

... Abstract Phosphate conversion coatings are widely used on (premium) casing connections for protection against corrosion. Next to that, in conjunction with the lubricant these coatings provide galling protection. The friction and wear that occurs during make-up and subsequent load cycling...

... Tubular expansion for well construction is a process accomplished by pulling (or pushing) a mandrel through a pipe downhole. This can be described as a tribological system that consists of the pipe and mandrel surface, a lubricant layer and a fluid. A successful expansion requires a lubricant...

... been conducted on NAF lubricants and 4% by volume of the preferred lubricant was added to the active system while drilling out the 9-5/8-in. shoe track. The lubricant was effective in reducing the drilling torque (actual torque reduction of 10% observed) and had a secondary benefit of thinning the mud...

... Abstract Lubricants are often added to the completion or drilling fluid, in order to reduce friction between tubular equipment run into the well, and the wall of the well. This paper shows in detail how the addition of a lubricant to an oil based drilling fluid affected the lubricity...

... was initiated to look for solutions to the torque problem. The scope of the investigations included consideration of different drilling fluid base oils, solid/liquid lubricants, and mechanical means to reduce torque. Small-scale screening lubricity testing was performed in a controlled laboratory environment...

..., and careful calculation was made to mitigate any possible equipment failure. There are various ways to address hoisting capacity problems. Among them are weight reductions, lubricants, and torque reduction additives. In this case history, each of these primary methods was employed to install a hook-type TAML...

... the tight gas sands which characterise the Anglia field were widely thought to have suffered permeability damage when drilled with oil-based muds; lubricity the long well-paths through the highly abrasive reservoir together with the requirement for slide drilling when steering required a highly...

... for this project. In terms of drilling mechanics this fluid, which incorporates a lubricant to reduce rotary torque and to aid sliding, had provided few problems. Difficulties have arisen on the gas fields due to gas migration behind both the 13 3/8 in. and 9 5/8 in. casing. This had not been a problem on the 11...

The WBFS was used to study effects of six operating factors on friction coefficients of unweighted lignosulfonate mud with and without a lubricant. Simulated cuttings beds were added for half of the tests. Effects of cuttings...
