Water is the material used to make drilling mud, cement slurry making and personal necessities that need to be surveyed hari.Untuk first water source is on site or nearby locations. The water source can be from rivers, lakes, and marshes. If the supply of surface water resources are not sufficient it is necessary to drill groundwater, and if it is not found in the location of water sources, the water is transported to the site by using tank cars.
Once the source of water is prepared subsequent installation of water channels and pumps, water supply is usually stored in a large tank in the vicinity of the drilling.

Preparation of Drilling Equipment.
Based on drill targets that would need to be prepared drilling equipment. Drilling equipment should be prepared of the problems that may be encountered. The equipment is prepared based on the depth of the target can be planned size and capacity of the tower that will be used. Based on formation pressure that will be on the face, Blow Out Preventer prepared accordingly.
Aside from the equipment needs to be well prepared materials that will be used for drilling operations, such as drilling mud materials and materials for cementing.
rig Up
The arrival of the drilling rig on location is usually in the form of parts, contractors and personal-personal by using heavy cranes to immediately begin the installation and erection of the tower drill. Rig up is stringing drilling equipment on site, and a minaret. The equipment is installed needs to be carefully examined, on the strength of the connections and apparatus, in order to avoid accidents that can damage the equipment and possibly befall workers.
The first phase of rigging up is started installing substructure directly after manufacture finished cellar. At the time of installation of substructure has been prepared and the foundation of the rig has been installed, prime mover and drawwork have mounted position and then try to immediately be able to use and run.
The next stage carry over head installation tools in place after the installation of line finished drilling one end connected to the drawwork. With the completion of this stage can be used to help the establishment of derrick in an upright position. Stages of the above can be illustrated through the following images:

Basically preparatory stage rigging up almost be said to be near completion, the drilling site had been transformed into a complex of modern rotary drilling.
