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. Traditionally, people in Mesopotamia used bitumen to make boats and hold earrings, necklaces, and bangles together. The Kings of Egypt used bitumen for the construction of the famous pyramids. 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. At the time, oil was used as medicine and the Chinese also lit their lamps as well as warm their houses using this product. There was not much knowledge of oil and the people came up with myths about the earth releasing gases and liquids.
The next discovery to be made as you will find here, was the spring pole. 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. Oil was still not the primary goal but the people believed it could serve several purposes. 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. Following this information, people saw the importance of oil and processes to extract it began.
From this website, you will read more about how the need for oil increased significantly. 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 historic moment was witnessed in Texas where a rig in Beaumont struck oil and it rose to the surface trickling like rain water. 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.
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. As you will see here, the rigs are enhanced compared to the past. For example ,as you see here is that one rig can drill multiple oil wells and even move on their own.
