There has been evolution in oil production technology today compared to how it was in the past as you will learn more here. Considering the value of oil to our lives, it is suitable to review the changes that have followed its discovery. The ancient people in Mesopotamia used a hardened substance called bitumen to construct sailing vessels and put jewelry pieces 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.
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. 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. 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. Oil was still not the primary goal but the people believed it could serve several purposes. With the introduction of steam to power ,the spring pole salt extraction proceeded at higher rates. 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. While drilling using the spring pole, the machine encountered a challenge going past the hardened sediments. Consequently, a method called rotary drilling emerged whose head could move past the hard sediment with great ease. One historic moment was witnessed in Texas where a rig in Beaumont struck oil and it rose to the surface trickling like rain water. As the world war 1 was set to begin, the demand for this product increased resulting in dire need for improved equipment following strong competition among nations. The most successful development for the rotary drill was the ability to dig deeper.
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. From what you have read in this website, you can see that the rigs can do more work than they did in the past. For example ,as you see here is that one rig can drill multiple oil wells and even move on their own.
