There have been significant changes in technology in the production of oil since its first production 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. In Egypt, it was used to solidify the famous pyramids. Bitumen, asphalt and motor led to increased curiosity about oil among people.
The first method used to extract oil was by digging up the soil to reach the oil. 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. 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 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.
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. 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 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. 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.
