  5. Directional drilling has been practiced by the oil and gas sector since the 1920s. Early directional drilling employed the same fundamental tools as vertical wells, with the exception that the drilling itself was carried out at an angle other than vertical. This procedure has been improved by the use of drill bits that can bend to better accept non-vertical angles in modern directional drilling techniques. The effectiveness and dependability of this procedure have been further enhanced by additional technologies, such as the use of hydraulic jets to guide and alter the drill's path.

If you find that the drill bit is getting too hot, take a break and allow it to cool down before continuing.read here this guide
