Which lubricant is best for drilling mud?

LUBE-1 shows the highest lubricity performance when added alone to the mud. HEAVY OIL and DIESEL have negative influence on drilling fluid's lubricity. High chloride ion content has a negative effect on fluids lubricity and rheology. Increasing the mud weight in lubricant added mud has positive effect on lubricity.

What is the lubrication performance of drilling fluid?

The lubrication performance of drilling fluid includes the lubricity of the fluid and the lubricity of the mud cake.

What lubricants are used in water-based drilling fluid?

Therefore, it is decided to combine lubricants and crude oil/diesel oil in our water-based drilling fluid and to determine the best composition which has good lubricity performance and low cost. Water-based lignosulfonate mud is chosen as our base drilling fluid.

What is drilling fluid lubricant?

But drilling fluid lubricants commonly used in the field are usually mineral oil, vegetable oil, which are easily to cause environment pollution, and have been gradually abandoned. Using biodiesel and polyether amine as the main raw materials, a novel drilling fluid lubricant HPR-1 was developed by series amidation reactions.

Can Biolubricants be used in drilling fluids?

This study reviews the application of general lubricants in drilling fluids and the potential of biolubricants derived from vegetable oils in exceeding the performance of hydrocarbon and mineral-based lubricants. Overall, biolubricants possess most of the physicochemical properties required as a lubricant for drilling fluids.

Are lubricants additives in drilling fluids?

Even though a considerable amount of research has been conducted and published on lubrication in drilling operation, only a few of these studies have reviewed lubricants as additives in drilling fluids, especially vegetable oil-based biolubricants.
