There has been evolution in oil production technology today compared to how it was in the past as you will learn 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. In Egypt, it was used to solidify the famous pyramids. Bitumen, asphalt and mortar although did not require drilling, were the substances that led to the discovery of oil.
From this site, you find out that oil was first extracted by digging. The people living in this period used oil to heal diseases, light their lamps and heat their houses. Little information about oil existence was available at the time as you have seen in this site.
The next advancement in technology came in form of spring poles. 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. The importance of oil was still not known to people at this time even though they knew it was a multipurpose commodity. When steam was introduced to provide energy for the spring pole for the extraction of salt the process became enhanced. A Yale chemist Benjamin Silliman discovered more about how oil could be converted into kerosene that is used for lighting lamps. 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. 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. As a result, a technique called rotary drilling was developed whose head penetrated the hard rock without the need to remove debris regularly. One historic moment was witnessed in Texas where a rig in Beaumont struck oil and it rose to the surface trickling like rain water. With the world war 1 coming around, the demand for oil rose, leading to increased competition which resulted in greater development of oil tools. The most important aspect of the rotary drilling method was to extract oil found very deep into the earth.
Today, the most common method of extracting oil is the rotary rig. However, they are advanced technologically as they are fitted with digital tracking devices, touchpads and video control to monitor and access the rigs from a fur. Besides that, the rigs are more sophisticated. For example ,as you see here is that one rig can drill multiple oil wells and even move on their own.
