The technology in the production oil has not been left behind in advancing as you will read more here. Because of its importance in our lives, it is best if we take a look at the changes that have taken place since it was discovered. 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. These minerals which oozed to the surface freely requiring no extraction equipment led to the discovery of oil.
From this site, you find out that oil was first extracted by digging. At the time, oil was used as medicine and the Chinese also lit their lamps as well as warm their houses using this product. Following the lack of valuable knowledge about oil as read in this site, there many false assumptions about oil fields at the time.
The next discovery to be made as you will find here, was the spring pole. The spring pole equipment as you will discover here was tied to a tree which made it possible to reach more depth and was increasingly used by the Ruffner brothers to make salt extraction easier. Despite a hint of the possible things oil could be used for at this time, oil was still not a necessity. When steam was introduced to provide energy for the spring pole for the extraction of salt the process became enhanced. 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 will find out in this website, the demand for oil was to rise in the near future. More oil deposits were also discovered deeper in the earth. 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. One event that marked how effectiveness of the rotary drill in the process of oil extraction was observed in Texas when a rig struck a rock resulting into a lot of oil flowing to 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 greatest achievement for the rotary drill was the ability to reach greater depths that the spring pole wouldn’t.
At the moment as we learn more here, rotary rigs are still in use for extracting oil. Even though the rotary rigs are still in use, they have been modified to today’s technology. From what you have read in this website, you can see that the rigs can do more work than they did in the past. An instance, is the ability of a rig to move on its own as well to extract oil from a number of fields.
