The procedure of oil drilling requires people who can expertly use oilfield equipment. These people are part of a crew that drills a hole from the starter and drills a hole from the depth that is already preset for the drilling. The process of drilling for oil involves a variety of different steps in order to be successful.

  • They place the drill bit in a hole along with the collar and drilling pipe.
  • A turn table and the “Kelly” are attached for drilling with the oilfield equipment.
  • The oilfield equipment helps to circulate the mud that goes through the pipe and out of the bit for floating the rock cuttings outside of the hole.
  • New sections or joints in drilling are added in the pipes when the hole gets deeper.
  • The pipe is later removed or tripped out along with the other oilfield equipment such as the bit and the collar once they reach their preset depth which can be anywhere from just several hundred feet to a couple of thousand feet.

The oilfield equipment such as the drilling gear must be placed on the casing pipe section that is in the hole to prevent the equipment from collapsing in on itself. The outer part of the casing pipe has spacers that help keep the focus on the hole. The pipe is pumped down by a cement crew with the help of a oilfield equipment such as a top plug, cement slurry and a drill mud. It is the pressure from the drilling mud that causes the cement slurry to move through the pipe casing to fill in the space that is outside of the hole.

Often a reserve pit is dug with oilfield equipment for disposing of the rock cuttings that they get when they are drilling the hole for oil. It is also for the drilling of mud and border it with plastic for the protection of the environment in the area. This is especially true if the area they are considering drilling is ecologically sensitive like a wilderness area or a marsh.

After the land is prepared for drilling different oilfield equipment will be used to prepare the land and digging several holes to make room for the oil rig as well as the main drilling hole. They also will dig a cellar, this is a rectangular shape hole that is dug around the location of the actual drill hole. This is a place for the workers as well as a place for holding drills and different accessories.

This is just a few things that are needed to be done in order for an oil crew to start pumping out oil. It is a vastly complicated job and takes a variety of different skilled people in order to make it happen.
