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. 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.
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 next advancement in technology came in form 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. 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. It is at this point that the society became interested in the commodity and commercial drilling began or view here for more info.
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. 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. Besides been in use, the equipment has had significant changes technologically to improve efficiency. As you will see here, the rigs are enhanced compared to the past. An instance, is the ability of a rig to move on its own as well to extract oil from a number of fields.
