Drilling muds: graphite as a lubricant additive

Drilling muds are used for the excavation and extraction of minerals, oil and gas in subway deposits. By adding graphite to the mix, a lubricating mud is obtained that reduces the friction on the drilling lances, thus increasing their life and allowing the extraction of minerals at greater depths.

Drilling muds: graphite as a lubricant additive

Why is graphite used in drilling muds?

Because one of its properties is lubrication, and as a drilling lubricant it reduces the stresses that can occur by having different types of pressures during excavation; thus controlling the peaks and leaks that may exist, to maintain temperature stability.

It should be noted that this process is applied to different industries such as: mining, gas and oil. In this occasion, we are going to focus on the last two.

The process of drilling muds in the oil or gas industry, makes the extraction characteristics are different, since they must have a fluid that resists the element that is being extracted and that in turn does not contaminate the process.

Here it is vital to be supervising at all times the viscosity, density, temperature, PH, etc. to ensure that the people who are above run the least possible risk. A sludge engineer is in charge of all this, verifying that all relevant controls are met.

Drilling mud lineups

They must also control the following in drilling muds:

  • The pressure that the subsoil has at the time of extraction.
  • To stop with a gelatinous element the different formations, while testing, so that they do not fall to the bottom of the sea.
  • To obtain the maximum stability, so that the process is carried out and no accidents occur.
  • Minimize the impact of drilling on the ecosystem and in turn on the environment.
  • To avoid corrosion in the machinery
  • To cool and lubricate the bit, which is the instrument that breaks, cuts or crushes the rocks, as the case may be.

Graphite for oil and gas extraction To carry out the process with drilling muds we have just seen, different properties of extraction graphite are used. For example:

  • The pressure that the subsurface has at the time of extraction Drilling muds have variations in pressure and require an element to control that pressure. For this reason, graphite is used, to be able to have visibility at all times of what is happening through its chemical reaction.
  • To obtain maximum stability, so that the process is carried out and no accidents occur.

By adding graphite powder to the process, it generates stability and you can be sure if there is any change; the element has the properties to resist and that gives the sludge engineer another type of visibility to make decisions.

  • Minimize the impact of drilling on the ecosystem and in turn on the environment.

As part of one of the most valuable resources obtained from mines, graphite is a natural element that with responsible excavation can be obtained without harming the environment.

  • Avoiding corrosion in machinery Avoiding corrosion in machinery Another of its many characteristics is that it prevents corrosion, because of its resistance to thermal shock.

Therefore, in ESGRAF we have graphite powder of different granulometries and lubricating properties for the production of drilling muds.

Conclusions

To conclude, thanks to its multiple properties, graphite is the key element to carry out the drilling mud processes; both in mining and in the oil and gas industry. Adjusting to the various stages that must be carried out to perform drilling properly.
