Liner is basically a kind of casing the main difference b/w liner and ordinary casing is that , the ordinary casing extends from surface to particular depth but in case of liner it does not extend from surface to particular depth but it attaches with the last part of the above casing .For example if you have drilled TD of 15000 ft and you have to install a liner at the bottom and suppose the liner length is 200ft.All the other casings will be installed from surface to to its particular desire depth but liner will be installed at the bottom of the other casings .
Advantages
1.Economics: you save the cost of 14800 ft of steel or aluminum .
2.Reducing the pressure at the surface: If you install a liner having a length of 15000 ft it will produce a lot of pressure on the surface .

What is difference between reaming and drilling?
Drilling is a cutting process in which drill is used to make a hole. Drilling process usually creates rough surfaces. Therefore, reaming is done after drilling to make a good surface finish, without changing the chemical and physical properties of the material. In reaming, only 5% of the material is removed (rest is removed by drilling process done before).
What is center drilling?
It is the process of drilling a locating hole at the end of a shaft while machining between centres.
What the importance of drilling center and guided drilling?
Drilling centre and guided drilling get your hole in precisely the correct place.
What is a sensitive drilling machine?
A sensitive drilling machine is an upright drilling machine. However, a radial drilling machine is also considered a sensitive drilling machine.
What is the difference between drilling and directional drilling?
Conventional Drilling is the drilling of a vertical well through reservoir rocks to TD. Directional drilling is the drilling of a non-vertical well horizontaly through a source rock.
How does the self-drilling feature enhance the efficiency of the drilling process?
The self-drilling feature enhances drilling efficiency by eliminating the need for pre-drilling pilot holes. This saves time and effort by allowing the drill to penetrate and secure materials in one step, making the process faster and more convenient.

How do self-drilling screws simplify the process of fastening materials together?
Self-drilling screws simplify the process of fastening materials together by eliminating the need for pre-drilling a hole before driving the screw into the material. This saves time and effort, making the fastening process more efficient.
What parts of the Chinese drilling process do the glass of water THE straw and the empty glass represent?

What type of fluids does drilling fluid belong to?
Drilling fluid, also known as drilling mud, belongs to the category of drilling fluids used in the oil and gas industry. These fluids are essential in the drilling process to lubricate, cool, and support the drill bit, as well as aid in removing cuttings from the wellbore.
How is the process of drilling into rock carried out efficiently and effectively?
The process of drilling into rock efficiently and effectively involves using specialized equipment such as drill bits and machinery that can penetrate the hard surface of the rock. The drilling operation is carefully planned to ensure the right location and angle for maximum effectiveness. Additionally, proper maintenance of the equipment and skilled operators are essential for a successful drilling operation.
Function of circulating mud system?
Drilling fluids circulating mud system is an important and obligatory constituent part in the modern drilling equipment, it can keep the mud normal circle and stable performance in drilling process, ensure drilling works on the premise of safety, environmental protection and high efficiency.
Why is mud used when drilling?
Mud is used in drilling to cool and lubricate the drill bit, carry rock cuttings to the surface, provide pressure to prevent blowouts, and form a protective barrier to stabilize the wellbore. It helps improve drilling efficiency and safety by ensuring the smooth operation of the drilling process.

Does geothermal drilling disrupt habitats?
Geothermal drilling can disrupt habitats if not properly managed. The drilling process itself can disturb the land and any existing ecosystems. However, proper planning and mitigation measures can help minimize the impact on habitats.
