There has been evolution in oil production technology today compared to how it was in the past as you will learn 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 pharaohs in Egypt used the substance to make the pyramids stand tall. Bitumen, asphalt and mortar although did not require drilling, were the substances that led to the discovery of oil.
The first method used to extract oil was by digging up the soil to reach the oil. At the time, oil was used as medicine and the Chinese also lit their lamps as well as warm their houses using this product. Following the lack of valuable knowledge about oil as read in this site, there many false assumptions about oil fields at the time.
The next advancement in technology came in form 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. However when steam power was introduced, the brothers were able to drill salt at a faster rate. A Yale chemist Benjamin Silliman discovered more about how oil could be converted into kerosene that is used for lighting lamps. It is at this point that the society became interested in the commodity and commercial drilling began.
As you learn more about how the demand for oil surged in this website. The number of oil deposits discovered in the earth increased. During the drilling process there were sediments that obstructed extraction of oil and the need for better machinery came up. Thus the rotary whose drill head went deeper past the sediment without the need to clear the debris constantly was developed. The success of the rig was witnessed in Beaumont Texas where the drill hit a field and a lot of oil started flowing towards the surface. 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.
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. As you will see here, the rigs are enhanced compared to the past. One such case is the increased mobility of the rig to extract oil from several oil wells.
