Drilling Process
Seismik
After a survey was conducted by geologists, geological surveys in the form of surface,
subsurface and seismic surveys, it can be stated that there are some traps below the
surface. Traps contents can not be known before the trap was breached. Having
obtained a trap reservoir and on the surface where it is considered illegal by itself should
make this place into a place that allows the implementation of drilling operations, then
determined the point of drilling locations. Various drilling techniques made to penetrate
the productive formation layers. In general, the drilling method is divided into two main
classes, namely cable tool drilling and rotary drilling.
Reservoir
The main objective of the drilling operation is to make a hole in a rapid,
economical and safe to penetrate the productive formation. Hole drilling results is called
"Well Bore" (the well). Once installed and cemented casing, the next step is installing
production facilities for producing oil or gas from the reservoir to the surface.
Drilling Process
Drilling operation is a job that requires large expenses or capital intensive, high
technology and high risk. The personnel who work on drilling operations should have a
good knowledge also about safety. So that drilling operations can run smoothly, and
accidents can be avoided.
The contents of the eye is more focused training to provide basic knowledge of
drilling techniques including understanding of drilling and drilling activities prior to, the
types of drilling, rotary drilling system, the system cementing, well completion and well
services.
In the normal drilling operations there are five systems that are very important in the
smooth process of drilling, namely:
1. Power Systems (Power System)
2. Bracing System (hoisting System)
3. Play Systems (Rotary System)
4. Circulation System (Circulation System)
5. Wild Shot of Prevention System (BOP System)
