How Oil Drilling is Prepared and Set Up

by Admin on May 12, 2013

Oil is an essential fossil fuel that can be found in several countries in the world. Geologists are the ones who locate the places where there is oil. Most of the time, these professionals are paid by a particular oil firm or a private company. With the most suitable state of area, they can locate this fuel from an oil trap. The modern times have paved the means for geologists to find oil in a more efficient way through the use of current technologies.

Before drilling an oil well, the site should be carefully chosen first. It is necessary to survey the area to identify its border lines. Legal issues, including jurisdiction, must also be taken into consideration. Optionally or whenever needed, the impact to the surroundings is also studied to make sure that the task is feasible.

The land is then prepared and made part parallel to the ground. If needed, access roads can be built around the area. A reserve pit is also dug on the ground for the disposing of mud and rock. There should be a water source somewhere near the area; otherwise, water well is drilled to have the source needed.

Afterwards, many holes will be dug to give means for the main hole as well as the rig. As for the actual hole of drilling, another area will be built and it will serve as the working space of the workers. The main hole is then drilled. This is usually done with the use of a small truck used for drilling. It can be noted that the first area of the hole is bigger and thinner than the core part. More holes are dug in order to have a place where the equipment can be stored in the short term. After these holes, the rig equipment can be arranged for utilization.

The next step is arranging the rig equipment. The transportation of this equipment largely depends on the accessibility of the site. It can be transferred by a truck, a barge, or a helicopter. The major systems of a rig include the following: rotating equipment, mechanical system, circulation system, power system, blowout preventer, derrick and casing.

Let us take a closer look at the important parts of the major systems of a land oil rig. The rotating equipment consists of drill bits and string, turntable, Kelly and swivel which are uniformly utilized for rotational drilling. The mechanical system has a turntable and hoisting system for carrying heavy items. The essential drilling mud is pumped by the circulation systems that involve mud pits, reserve pit, mud-mixing hopper, shale slide and shaker, pipes, hoses and pump. The power system has electric generators and large diesel engines. These are necessary for the source of electrical power.

It is only when the rig is complete set up that the workers can begin the operations for the drilling itself. It all begins in the starter hole where a surface hole is drilled down to a specific measurement. This measurement is somewhere over where the geologists think that the oil trap is situated. Upon reaching this depth, the casing is then cemented so as to prevent its collapse on itself. It is kept in the middle through the use of the spacers of the casing pipe. Afterwards, the stages of drilling are continued.

Today’s world is fortunate to have the modern technologies utilized in drilling oil. But then again, it is still a big question if our demand for oil can always be at par with the supply that we have. What matter most now is that studies are still conducted as to how oil drilling can be made more effective and efficient.
