Oil drilling industry is well thought-out as the most delicate industries in the planet. With the escalating demand of natural gas and oil diverse companies incessantly look forward to improve the production of existing wells. China is the first country which drilled oil wells that were depth about 800 feet. Ever since then it’s started the demand of oil and natural gas increases very speedily and in return oil industry benefited a lot over the years. Nevertheless the first oil drilling method was developed in 1859 by Edwin L. Drake. This modern method is still being used and is the most resourceful means of oil production. Around 800 billion barrels of oil has been used by the globe since 1859 and this makes it one of the most budding industries around the world.
Cody Winters is the President and Founder of Southlake Resources Group. He is an accomplished oil and gas businessman with extensive experience matching sophisticated investors and high quality operators. Today with the advancement of new techniques and technology, drillers can reach even those reservoirs which were considered as inaccessible. Geologists play a fundamental role in oil drilling process as they are the one who finds the best location for drilling according to his knowledge and experience. They might work independently or on contract basis with specific company. They are accomplished professionals who studied about the terrains and rock in order to select the best location or oil bed for drilling process.
The chief function of oil drilling is to pump out the oil and crude petroleum gases from the earth crust. Crude oil is found in its semi- solid or liquid state (in the form of tar). The reservoirs where crude oil is present can be hundreds of feet underground and thus only through drilling process it can be reached underneath the surface. According to Cody Winters, the oil can be drilled by any of the following drilling process:
- Offshore Drilling: In this method special oil drills identified as jack up rigs are used at the depth of 200 feet and when depth reaches 2000 feet under, the rigs are fastened to the ocean floor with the air filled bags. Moreover there are some drill ships that use refined navigational equipments to dig up to the depth of 8000 feet. Nevertheless there are many companies who are charged for the violation of the Clean Water Act as they continuously spread noxious gases and toxic chemicals into the water that harm marine life and other wildlife jeopardizing near these sites. This technique is very much similar to the other techniques used on land.
- Rotary Drilling: Today, it is the most common oil drilling technique used. You can be acquainted with by a rotating turntable at the base and a tall oil derrick. Special mud which aids to pull out the rock cutting and lubricates the drill bit is also required in rotary drilling process. The mud can be a mixture of clay, water and some chemicals.
Other methods for oil drilling are horizontal drilling and percussion drilling. The procedure is too long as occasionally it takes years to drill the oil wells and the whole process is very complicated and tedious that serves energy universally.
