What is slant drilling?

Slant drilling, also known as directional or horizontal drilling, allows oil reservoirs to be accessed at an angle other than vertical. This is achieved by maneuvering the drill bit in the desired direction. Slant drilling frees directional drilling from the traditional need to place the oil rig on top of where the oil is.

What is a slant rig?

Unlike traditional vertical drilling, slant rigs can bore holes at various angles, allowing access to reservoirs that are difficult to reach using conventional methods. The key feature of a slant rig is its ability to change the drilling angle as it progresses, thus providing precise control over the wellbore's trajectory.

What is a slant directional drilling rig?

Herrenknecht's Slant Directional Drilling rigs (SDD) combine the advantages of two drilling methods that have proven themselves for years. With the specially designed drilling technology, near-surface conventional or unconventional oil and gas deposits and geothermal energy can be developed safely and efficiently.

Are slant rigs the future of oil & gas?

In conclusion, slant rigs have emerged as an indispensable tool in the oil and gas industry, offering precise control and access to previously untapped reserves. As technology continues to advance, slant rigs will likely play an even more significant role in shaping the future of drilling operations.

When did slant drilling begin?

Slant drilling began officially in 1939, but its scope was limited due to technological constraints. Compared to modern methods, most drilling was hit and miss. Even if a field was known to exist, lateral extensions to the drill string could not go very far without disrupting the whole rig.

How does a slant well work?

A slant well avoids the high oil pressure at the original well by being drilled at an angle into the same reservoir. Once the connection is established, first seawater and then mineral mud is pumped into the reservoir to displace the oil.
