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. The ancient people in Mesopotamia used a hardened substance called bitumen to construct sailing vessels and put jewelry pieces together. The Kings of Egypt used bitumen for the construction of 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. At the time, oil was used as medicine and the Chinese also lit their lamps as well as warm their houses using this product. 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. 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 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.
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. During the drilling process there were sediments that obstructed extraction of oil and the need for better machinery came up. As a result, a technique called rotary drilling was developed whose head penetrated the hard rock without the need to remove debris regularly. 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. 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 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. Even though the rotary rigs are still in use, they have been modified to today’s technology. From what you have read in this website, you can see that the rigs can do more work than they did in the past. One such case is the increased mobility of the rig to extract oil from several oil wells.
