It is simple to understand the type of drilling from the name itself. Directional drilling is a broad term but, it mainly means something that does not go in a straight line or vertically down. This type of drilling has been in use for almost 100 years. There have been numerous improvements made to this type of drilling. They have added new features to perfect the drilling process like technological additions, turns, and underground distances as well. The unique thing about this is that it protects the ecosystem and reduces a project’s overall loss in terms of the environment.
Whereas, the traditional methods include auguring, bentonite mud drilling, and rock core drilling. Auguring drilling is done with a helical screw and it goes into the ground while rotating itself. Even though bentonite is a traditional method, it is still very common. This is used for drilling fluids. Bentonite is the flush fluid and this lubricates and cools down the cutting tools while protecting them from corrosion. Lastly, the rock core drilling uses rotatory coring which advances the borehole simultaneously. Therefore, there are a lot of disadvantages that come with the traditional methods because they have not been developed throughout the years.
Comparison and reasons to choose directional drilling
This drilling has many benefits, but the most important benefit is that it allows companies to extract multiple oil reservoirs from one well. This eliminates the need for drilling in multiple locations. This helps to reduce drilling costs. This type of drilling increases the efficiency of oil-and gas extraction. This drilling is also very efficient and can extract a lot of oil and gas by drilling only once. It does not pose a threat to the environment. This drilling also reduces soil disturbance. This is because drilling reduces the surface area that is being used, which can make oil and gas extraction less disruptive for those living nearby.
Some general facts
This drilling technique has been used since the 1920s. Despite being safe, the methods used were often insecure and inaccurate. Modern technologies are now available to improve the accuracy and safety of this method. Hydraulic jets are one example of these new technologies. This machinery adjusts and guides drill direction. This technique can be improved by taking additional measures. There are also drill operators. These people use computers to adjust drill bits’ angles in real time. They can also use GPS signals for pinpointing the location of an oil field or gas field.
This has increased the reliability and accuracy of their software. Advanced software programs are now used by them. Engineers can now create 3-D models from the oil and gas fields to help determine the best place for drilling. This allows them to determine the best place for drilling to occur. This drilling technique is used primarily in areas where underground reservoirs aren’t in good shape or are unusual-looking. This type of drilling is used in areas where vertical entry is not possible. They are also used where residents have concerns about drilling in these areas. The drilling location and the exact site determine the drilling length. Only then will they be able to determine how far drilling can take place.
