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. 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. Bitumen, asphalt and mortar although did not require drilling, were the substances that led to the discovery of oil.
The technique used to obtain oil on its discovery was by simply digging. The people living in this period used oil to heal diseases, light their lamps and heat their houses. 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 discovery to be made as you will find here, was the spring pole. 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. Benjamin Silliman a chemist at Yale learned more about processes that could convert the oil into kerosene that could then be used in 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. 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 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. Because the world was getting ready for the first war, the need for oil skyrocketed leading to the development of better oil tools as a result of competition. 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.
