There have been significant changes in technology in the production of oil since its first production as you will read more here. Since oil is an essential commodity for the survival of man, a look into the changes in technology in production is a good idea. In the past, in Ancient Mesopotamia bitumen a hardened substance was used in ship construction and holding jewelry together. The pharaohs in Egypt used the substance to make the pyramids stand tall. Bitumen, asphalt and mortar although did not require drilling, were the substances that led to the discovery of oil.
The technique used to obtain oil on its discovery was by simply digging. The people living in this period used oil to heal diseases, light their lamps and heat their houses. Following the lack of valuable knowledge about oil as read in this site, there many false assumptions about oil fields at the time.
The technology that followed drilling was the use of spring poles. This apparatus which was connected to a tree was made popular by the Ruffner brothers with the intention of reaching more salt deeper in the earth. Despite a hint of the possible things oil could be used for at this time, oil was still not a necessity. However when steam power was introduced, the brothers were able to drill salt at a faster rate. A chemist at Yale by the name Benjamin Silliman discovered more about distillation of oil into Kerosene that could be used in lamps to provide lighting and even cook. It is at this point that the society became interested in the commodity and commercial drilling began.
As you learn more about how the demand for oil surged in this website. The number of oil deposits discovered in the earth increased. However there were hard sediments that made drilling difficult hence the need for improved equipment. Thus the rotary whose drill head went deeper past the sediment without the need to clear the debris constantly was developed. The success of the rig was witnessed in Beaumont Texas where the drill hit a field and a lot of oil started flowing towards the surface. Because the world was getting ready for the first war, the need for oil skyrocketed leading to the development of better oil tools as a result of competition. The most successful development for the rotary drill was the ability to dig deeper.
Today, the most common method of extracting oil is the rotary rig. Besides been in use, the equipment has had significant changes technologically to improve efficiency. From what you have read in this website, you can see that the rigs can do more work than they did in the past. One such case is the increased mobility of the rig to extract oil from several oil wells.
