There are 5 main techniques that the well-drilling companies use. The first among them is percussion drilling. You can learn more about it at an IWCF training class. Percussion drilling is also referred to as cable drilling. It is basically a manual drilling technique where you use a hammering bit and attach it to a long cable. After this, the cable gets lowered into a hole that is wide open. The reason why this is also known as cable drilling is that here the driller uses a tripod to provide the tools with some much-needed support.
Rotary drilling is one of the commonest methods of drilling as well. This is especially true when it comes to digging production and exploratory wells. These wells are normally deeper than 5 miles into the ground. You can be sure that you would be able to learn it at an IWCF certification program. In this particular method, the drillers use drills that are light in terms of weight. The process starts with drilling wells, which are of a low depth, on land. The rotary floating and mobile drills used over here are of different sizes. The drillers use these drills at the second stage to dig the exploratory wells.
Dual wall reverse circulation drilling
Dual wall reverse circulation drilling is a kind of rotary drilling in itself. This is something that you would learn at an IWCF training session. In this kind of drilling, the drillers use a couple of concentric drill pipes in order to create a flow. This flow is a controlled one in nature. The drilling fluid is then pumped via an outer swivel. The aim, in this case, is to get to the end of the pit. After this, the pipes ricochet back towards the main pipe. In this case, all the cuttings are taken upward by using an internal pipe and a surface swivel.
You can be sure that an IWCF certification program would teach you the process of electro drilling as well. In this method equipments such as rotary tables and wenches are used, and they are driven by an electric motor. This, in turn, makes it easier to achieve a higher degree of flexibility. In this case, you can also control the drilling process with remote control. As far as oil and gas exploration is concerned this happens to be one of the newer methods.
As any IWCF training class would tell you directional drilling can be regarded as an extension of rotary drilling. In this case, the drill is guided on a path that is curved. It becomes more curved even as the hole starts getting deeper. With the help of this kind of drilling, you would be able to get across to deposits that you otherwise would not be able to reach with the help of vertical drilling. The biggest benefit of this particular method is its lower costs. It also allows a number of holes to be drilled in various directions and that too on the same platform.
