The technology in the production oil has not been left behind in advancing as you will read 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. Traditionally, people in Mesopotamia used bitumen to make boats and hold earrings, necklaces, and bangles together. In Egypt, it was used to solidify 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. There was not much knowledge of oil and the people came up with myths about the earth releasing gases and liquids.
The next discovery to be made as you will find here, was the spring pole. 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. Oil was still not the primary goal but the people believed it could serve several purposes. 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.
From this website, you will read more about how the need for oil increased significantly. The number of oil deposits discovered in the earth increased. 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. 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.
Today, the most common method of extracting oil is the rotary rig. Besides been in use, the equipment has had significant changes technologically to improve efficiency. Besides that, the rigs are more sophisticated. One such case is the increased mobility of the rig to extract oil from several oil wells.
