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. 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. These minerals which oozed to the surface freely requiring no extraction equipment led to the discovery of oil.
The technique used to obtain oil on its discovery was by simply digging. In this site you learn more about how the traditional people used oil to treat diseases, light lamps to increase visibility and keep warm. Little information about oil existence was available at the time as you have seen in this site.
The technology that followed drilling was the use of spring poles. The device as you discover more here, was attached to a tree which provided the required resistance to reach greater depth, was used by the Ruffner brothers to enhance salt extraction. 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. Benjamin Silliman a chemist at Yale learned more about processes that could convert the oil into kerosene that could then be used in lamps. After the discovery by Benjamin, there was more interest in this product and commercial extraction could be seen as you’ll see here.
As you will find out in this website, the demand for oil was to rise in the near future. Following the demand; there was an increase in the number of oil fields that were discovered. However there were hard sediments that made drilling difficult hence the need for improved equipment. Consequently, a method called rotary drilling emerged whose head could move past the hard sediment with great ease. 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 most important aspect of the rotary drilling method was to extract oil found very deep into the earth.
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.
