Directional drilling refers to any boring services that don’t go vertically straight down. The reason behind the deviation is to avoid previous stuck pipe or geological formation and then get back to the original path. In such a situation, the driller can use sidetracking techniques.
Here are 5 things you should know about directional drilling:
1.Value of technique
This drilling method can drill multiple down holes from the same rig, helping to minimize the environmental impact or surface disturbance. Besides, the boreholes can also extend down up to a mile and when at shallow angles, it can go up to five miles.
When working in oilfields with dispersed deposits, it is possible to trap a large radius and therefore to minimize expensive asset.
2.Detecting drill ends
When drilling, it is not possible for engineers to see down the underground. They have to rely on technology, that shows them the direction they are going.
There is a guide for directional driller that geologists and engineers create. In every 10-150 meters, a survey data is received to ensure that they are following the original “blue line.” For more info in directional drilling visit https://www.atbservices.com.au/
3.How Drill Make a Turn
When imagining about the directional drilling mechanics and you have not seen the technology, you will wonder how the drill changes its direction. The motor turning the drill is always on the surface.
Rotary steering and turbodrills are the ones employed in the directional situations and when best suited.
Maintaining The High Pressure
In the wells, it is a big challenge for engineers to maintain the hydraulic pressure. With the modern advanced directional drilling equipment, they can cope with the high temperatures or pressure conditions.
5.Directional Well Planning
Drilling can’t function without a plan. Geologists and engineers use computer simulation programmes. The programs are 2D and recently 3D modeling to visualize the planned path.
