The first requirement to make a direct road towards a predetermined location would require equipment, land and personal. The road to the site to be surveyed, to see that the shortest distance, the street crowds, violence and road width, strength and width of the bridge. Preparation path to this location must pay attention to safety, both to workers, equipment, and the environment, mengingatperalatan-drilling equipment across the large and heavy.
Preparation Area.
To perform drilling operations on land the most important thing to note is the preparation of a drilling operation, while at sea should take into account the comprehensive platforms used and use the place as efficiently as possible for a very limited extent. Onshore drilling site preparation includes: Flatten location, location hardening, create pools of container, making cellar.
Average drilling site created to simplify tasks in placing the equipment on site. Drilling site was prepared with the minimum radius of 50 meters. Especially around the drilling site location points should be tempered, because it must withstand very heavy drilling equipment. Construction site should take into account the weight of the equipment that will be installed on it.
Figure 2.3. preparation Location
Drilling locations have also been leveled and is ready to further escavator start making a hole or a square-shaped pond not far from the location of the drilling. This pool is called the reserve pool (mud pit), before the pool was used to collect waste from the drilling mud during the drilling operation, the first need to be coated first with plastic lembaranlembaran. The next stage is to make the other pool rectangular shaped but smaller than the so-called mud pit cellar.
This large diameter cellar called “hole conductor” will be just below the floor after the rig substructure mounted thereon. After making a cellar finished and then make the wellbore, endeavored to do in the midst of the wellbore. Cellar is a rectangular pit made at point location, which is useful as an additional space below the drill floor.

Figure 2.5. Making Cellar and Conductor Pipe Installation
After the prepared hole conductor approximately reach a depth of 20 s / d 100 ft, then the hole is installed “conductor pipe”. Installation of the pipeline is to avoid the hollowed-gerowong or other damage to the wellbore during drilling operations conducted.
