How do Drilling Fluids Function?
The ability to drill deeper, longer and more difficult wells has been made possible through improvements in the drilling process, which include more efficient and effective drilling fluids. To assist in drilling, drilling fluids (also known as drilling mud) are added to the wellbore. They hold cuttings in suspension and control pressure, stabilise exposed rock, offer buoyancy and cooling, and provide lubrication.
Although the science and technology behind drilling fluids has evolved but the fundamental concept behind drilling fluids hasn't changed. Drilling fluids play an essential role in drilling success. They enhance recovery and reduce the time it takes to reach first oil.
Purposes Of Drilling Fluid
Cuttings may be produced in the course of drilling. However, they are not usually an issue until drilling has been stopped or a drillbit needs to be changed. When this happens, and drilling fluids are not been used, the resulting cuttings are able to fill the hole. To stop this from happening, drilling fluids are used to suspend the hole. The viscosity rises with movement and makes drilling fluid liquid when drilling takes place, and then turn into a solid substance once drilling has stopped. The drill is then used again. Once drilling resumes this gel-like substance turns back into liquid.

By reducing the pressure from the hydrocarbons , as well as the pressure of the formations of rock Drilling fluids can be used to regulate pressure in the well. Weighting agents are added to drilling fluids in order to boost its density and therefore, its pressure on the walls of the well.
Another major role that drilling fluids play is their rock stabilization. To ensure that drilling fluids don't absorb into the rock formation and that the pores do not get blocked, specific additives are used.
The deeper the well is, the greater amount of drill pipe is needed to for drilling the well. The amount of pipe is heavy, and drilling fluid also adds buoyancy, thus reducing stress. In addition, drilling fluid aids reduce friction with the rock formation, reducing heat. The cooling and lubrication helps to extend the lifespan of the drillbit.
Types Of Drilling Fluids
Drilling fluids can be water-, oily -, or synthetic-based. Each type of composition provides different solutions for drilling. For drilling fluids to work it is essential that the formations in the rock consist of clay or salt. A drilling fluid engineer is accountable for monitoring drilling and including drilling fluid additives into the process. This can help increase buoyancy or reduce friction, when needed.
A drilling fluid engineer should take into consideration the chemical composition as well as other properties of the well before selecting the appropriate drilling fluid to be used in the well. Oil-based drilling fluids may work better with a saltier rock. Drilling fluids that are water-based are typically considered to affect the environment less during offshore drilling.
Disposal of drilling fluids after they have been used can also be an issue. Recent technological advances have established methods for recycling drilling fluids. |
