Based on the US Energy Information Administration (EIA), the us imports roughly 9.8 million barrels daily  (bpd) of crude from all over the world while generating approximately 4.9 million bpd internally. All of these figures give a concept of the energy requires of this wonderful country which further illustrates why oil firms involved in drilling gas and oil have to constantly improve  the manufacturing of existing oil wells along with search for new resources for the black gold.  

The very first stage in the drilling of oil and gas is the acquisition of access and rights. This involves geologists and geophysicists identifying a potential hydrocarbon trap and finding out its potential. Land holders are associated with the negotiation of the prospect’s mineral rights as well as the drill place access. Regulatory agencies are contacted for the necessary enables and the companies can start the actual oil drilling process.

Step two includes the preparation of the website . This incorporates the putting up of the pilot borehole and the construction of the cement cellar which houses tools used for blowout prevention. This is achieved before the true drilling rig is setup. It ensures the safety and protection of the personnel at the website .

Stage three of [http://investmentsinoilandgas.com/oil-wells/drilling-oil-and-gas/ drilling oil and gas] incorporates the setting up of the conductor pipe that's a sizable diameter pipe which goes 20 to fifty feet into the surface. The conductor pipe is employed to keep the drilling rig into position by preventing the washing out of the hole round the rig floor. 

Step four of the process is facts about rigging up. This consists of raising the derrick mast, connection of the mud pumps along with the setting up of rotary drives, engines along with other connected equipment. This offers method to  the drilling of the rat hole which supports the Kelly and the mouse hole which supports the drill pipe or the joint. The Kelly transmits rotary movement to the drill pipe  by means of the drillstring.      

Step 5 involves drilling and spudding. Spudding refers to the start of the drilling process. The drilling construction that contains the drill bit, drill collar, drill pipe and the Kelly is lessened into the conductor hole. Once the initial drillstring length is utilized up, yet another joint is placed on to it and drilling continues. Drilling mud which is a mixture of oil or water based slurry is employed to remove the drill cuttings that's consists of loose mud and rock from the hole. The drilling mud is also used to cool off the bit as well as hold back subsurface pressures. 

Step 6 incorporates well logging once the total depth has been accomplished. This is primarily  a foot by foot analysis of  places  for instance  reservoir fluid conductivity, reservoir rock layer geometry, transmission of vibrational waves through the reservoir rock and its natural radiation. Each of these are essential  factors that determine the feasibility of a particular oil well.
