In the current energy scenario, oil and gas companies are carrying out vociferous exploration of reserves to cater to the ever-increasing energy needs. This includes tapping into both off-shore and on-shore reserves for oil and natural gas across the world using newer techniques for reaching out to well bores.
Directional drilling involves drilling wells at multiple angles and not just vertical drilling to obtain maximum productivity. The other advantage of directional drilling lies in reaching out to multiple wells through one vertical well bore, thus, helps to minimize the impact of drilling on the environment. For carrying out directional drilling, drilling contractors strive to change the angle of inclination of the drill hole. The desired functions are carried out using turbo-drills, mud motors, steering and measurement tools, and rotary steerable systems.
Directional drilling extends a host of advantages in terms of higher productivity and throughput rates over conventional vertical drilling methodologies. With soaring oil prices across the world, the need for process efficiency and higher productivity has necessitated the use of alternate drilling techniques such as directional drilling.
With the exhaustion of on-shore drilling sites for oil and gas reserves, it has become imperative for oil and gas companies to tap into off-shore reserves. To do this, oil and gas companies with the help of drilling contractors are utilizing directional drilling for improved control on the direction of the hole at off-shore drilling sites. The other advantage of directional drilling lies in retrieving drilling spear and other equipment at the wellbore. The technique also helps to dig a precise and clear hole for situations where metal is prohibited in the drilled hole.
The utilization of directional drilling is bound by strict governmental regulations in place for the associated environmental deterioration. Thus, companies that are involved in directional drilling need to look into issues for best-performance of these undertakings.
