Here are some notes I'm about wellhead



1. At the installation of casing head with the casing by using a welding performed in accordance with SOPnya preheater to avoid crak. After pressure testing is done usually by using a hand pump.

2. Shallow wells, while wells within 1500 feet of 3000 feet

3. The point is to position the riser BOP crismas tiknes tree is at ground level rather than on the surface of the cellar tiknes

4. The dimensions of the cellar is a 2m x 2m x2m. While the function of the cellar one of them is that the position of tree crismas tiknes not too high from the ground surface.

5. Formation on the drill pipe and wellhead his example is

a. Ø30 casing "in the plug as deep as the formation of soft ground.

b. later in the input bit ø26 "

as for the formation ø always smaller drill pipe from the casing

6. Mud from the drilling process is always in kembalikakn into the hole while drilling and other ground-other in the exhaust. In this process using a machine called Shell Saker (right ngak ejaanya anyway).

7. Usually the pressure test on the rules of Oil and Gas is 75% of the ability to withstand pressure tubing. And the rules of API adalh 1.5 xnya of ability to hold pressure tubing.

8. Function of pipe ram one of them is to stop bursts of pressure from within.

9. The function of the casing one of which is to restrain burst (pressure) that pass through soft soil formations. The point is the pressure from the bottom of the earth does not pass through soft soil formations but only through the casing.

10. Pressure (pressure) from the bowels of the earth as great as the sea water pressure. Semakain in the pipe the greater the pressure.
11. Formation is the casing, then the new Wellhead Crismas tree.
