Drilling Fluid



drilling courses in Rawalpindi

Drilling fluid is used anytime a hole is drilled deep into the Earth. This includes oil drilling, gas drilling, water drilling, and exploration drilling. Technical Data used in the field explained in drilling courses in Rawalpindi, It is used because it helps provide hydrostatic pressure which keeps unwanted fluid from entering into the hole. Two additional functions of drilling fluid are to keep the bit clean and carry drilled cuttings out of the hole. The ingredients and chemical additives that are found in drilling fluid can vary significantly according to the type of formation being drilled. In all, drilling fluid is a critical part of the drilling process which needs to be managed by Mud Engineers. Some more details of drilling courses in Rawalpindi are as under.
The drilling fluid must be properly engineered so that it moves the drill cuttings out of the bore hole. For example, it must be able to carry the cuttings up the hole but also keep them suspended while the drill is not in motion. To do this it must be able to become a gel-like substance when it is not circulated by the drill's movement. This allows the cuttings to "float" in the drilling fluid while the drill pipe is lengthened or while maintenance is carried out. If any of the drill cuttings fall to the bottom of the bore hole, it can result in stuck pipe and dramatically slow down the drilling process. Also, the longer it takes for the mud to remove the cuttings from the hole the more they break up and become more difficult to remove.
The formation's pressure is another thing that the drilling fluid controls. For example, if the pressure in the formation increases too much, barite is usually added to the drilling fluid to increase its weight. However, if the mud weight becomes too high it can cause instability and create fractures in the formation. Blowouts are caused by unbalanced pressures in the well. In addition to maintaining formation pressure, correctly managed hydrostatic pressures help to manage instability caused by shifts in the Earth's tectonic plates.
