What Is Horizontal Drilling?
In the development of technologies to drill for oil and gas, horizontal drilling or driller fracking is by far the most popular technique used. Many oil companies and exploration companies both in the U.S. and abroad are now using the process of directional drilling in order to find deposits.
Directional drilling involves the use of horizontal drilling equipment. It is used to access deposits that are found to be beneath the ground rather than on the surface, such as shale. Horizontal Drilling of this type is considered a high risk strategy.
To explain this better, horizontal drilling requires many different types of equipment to explore deep into the earth. These include: tunnelling machines, heaters, motors, lighting, seismic equipment, tractors, cutters, and drill bits. It requires the use of hydraulic pressure, directional instruments and directional drill bits.
The majority of horizontal drilling equipment is based on a screw pump. The purpose of this device is to provide pressure on the borehole, as well as allowing water to flow through the drill hole. This helps in the formation of stable seals that will help to prevent leaks.
Prior to directional drilling, drill holes need to be sealed. The horizontal drilling fluids that are used in the process are chemicals that act as a sealant and help to extend the life of the shaft and drill bit.
A separate service to prevent accidental discharge of fluids and gases from the horizontal drilling process is to seal the borehole, and the horizontal drilling itself, with flange seals. The flange seal will stop any leak from getting out of control and will also allow the drill bit to hold the seal firmly against the rock.
Another aspect of the Driller Fracking which needs to be considered is the movement of the drill bit during the exploration process. Since this is a new method of horizontal drilling, a lot of trial and error is required, since it is not common practice.
A service to use is called the pea cutter. This is used to drill shallow boreholes and then turn the bit at a high angle so that the bit hits the next section of rock and pushes it out of the way. This service should be used to minimize any chance of a larger whole, which could cause damage to surrounding structures.
The majority of horizontal drill bits are of the directional variety. These are chosen based on their ability to penetrate deep into the earth, and also their ability to retain their penetrating capability when they meet rocks.
The directionality of horizontal drill bits will depend on the quality of material being drilled. Some of the best quality bits are known as “knee-high” bits, while the worst are “heel-high” bits.
When choosing directional drilling services, it is important to find out what drill bit types they are using. Companies will use directional bits, and bits made from various materials, depending on the depth they plan to drill, as well as the areas that they plan to work in.
What is best for one operation may not be the best choice for another, so it is imperative to get a quote from different companies for the cost of their horizontal drilling services. Doing your research prior to contacting a company is essential to finding the best company for the job.
