Types of Fluids

In this world, most materials known to humans are classified as solids, liquids, or gases. However, liquids and gases can also be classified as common state, fluid state, or fluid (Smits, 2000). Fluid is one of the most important elements in our life. The water we drink, the air we breathe, the rivers that we flow, and the oils we use are all liquids. The fluids mentioned by Munson, Young, Okiishi, and Huebsch (2010) are defined as "substances that continue to deform when subjected to shear stress of any size" (p. 12).

Depending on the type of fluid used for drilling work, the extent to which drilling cutting is considered as dangerous is determined. The main types of fluid are Oil Mud (OBM) and Aqueous Mud (WBM). Synthetic mud (SBM) is also optional. The purpose of circulating the fluid into the well during the excavation work is mainly to stabilize the wellbore, control the underground pressure and formation pressure, control the well stability and corrosion, cool and lubricate the drill bit, and cutting waste To the surface of the earth.

Drilling fluid is used to control underground pressure, cool and lubricate the drill bit, carry chips to the ground and stabilize the wellbore. The main types of drilling fluid are oily (OBM) and aqueous mud (WBM). Compared with WBM, OBM provides better drilling performance in water sensitive strata. Baryte and bentonite are mixed with drilling mud to adjust weight and viscosity, respectively. Drilling mud and excavated debris are the largest waste in the offshore oil drilling industry (Sinsaas et al., 2007). OBM drilling tips are defined as hazardous waste and separated from mud by shale shakers. ThermoMechanical Cutting Cleaner (TCC) leaves OBM chips without oil and enables discharge to the sea

"Dirt" which is the drilling fluid is discharged from the inside of the drill pipe and the drill bit. Although the main components of the drilling fluid are usually water and clay, complex mixtures of liquids, solids and chemicals must also be carefully adjusted to provide the correct physical and chemical properties necessary for safe drilling included. Specific functions of the drilling mud include cooling the drill bit, lifting the chip to the surface, preventing rock instability in the well bore wall, and overcoming the fluid pressure in the rock, Including not entering the well. Several oil wells are drilled with air or bubbles as drilling fluid
