The Ultimate Guide to Directional Drilling: What Is its Purpose?

Posted on: 16 January 2024

Directional drilling is a groundbreaking technology that has revolutionised the oil and gas industry. It has made it possible to drill wells at previously unreachable locations, making the task of producing oil and gas more cost-effective, efficient and environmentally friendly. But what is the purpose of directional drilling, and how does it work? In this article, we will provide you with a comprehensive guide to directional drilling and its purpose.

What Is Directional Drilling?

Directional drilling is a drilling technique that allows engineers to steer a wellbore in multiple directions, not just in a vertical straight line. This means that instead of drilling straight down to reach the oil and gas reservoir, the well can be drilled horizontally or at different angles to reach areas that were previously impossible to reach. With directional drilling, engineers can target specific locations in the reservoir where the oil or gas is abundant, leading to higher production rates.

What Is the Purpose of Directional Drilling?

The primary purpose of directional drilling is to access remote or hard-to-reach locations. By drilling at an angle, it is possible to reach oil and gas deposits that are situated beyond traditional vertical wells. Directional drilling also makes it possible to drill a single well and access multiple reservoirs, which is more cost-effective and efficient than drilling multiple vertical wells. The technique also provides a way to avoid environmentally sensitive areas or difficult terrains such as mountains, forests and cities.

How Does Directional Drilling Work?

Directional drilling requires advanced drilling equipment, including a drill bit, drill string and a mud motor. The operator also needs a downhole navigation system that tracks the location and orientation of the borehole. The borehole's trajectory is guided by adjusting the inclination and azimuth of the drill bit in real time as drilling progresses. It is done by using wireline telemetry or mud pulse telemetry data. This helps engineers steer the drill bit towards the desired location, even as it progresses through different layers of rock.

What Are the Benefits of Directional Drilling?

There are several benefits to using directional drilling. In addition to accessing hard-to-reach deposits, the technique also reduces the number of wells needed to produce the same amount of oil and gas. This reduces the disruption of the natural environment, lowers costs and improves efficiency. Directional drilling also allows for better resource management since it is possible to drill multiple wells from one location. The technique is also safer since it reduces the risks of drilling accidents.
