![]() Horizontal drilling is any wellbore that exceeds 80 degrees, and it can even include more than a 90-degree angle (drilling upward). The Horizontal Directional Drilling (HDD) Industry has experienced so much growth in the past two decades that HDD has become commonplace as a method of. Here, a horizontal well is drilled across an oil and gas formation, increasing production by as much as 20 times more than that of its vertical counterpart. One type of directional drilling, horizontal drilling, is used to drastically increase production. Then, once the angle is reached, the complete drillstring is rotated, including the bend, ensuring the drillbit does not drill in a different direction from the wellbore axis. In this case, the bend directs the bit in a different direction from the wellbore axis when the entire drillstring is not rotating, which is achieved by pumping drilling fluid through the mud motor. A more complex way of directional drilling utilizes a bend near the bit, as well as a downhole steerable mud motor. Directional drilling is a broad term used to describe any boring that doesnt go in a straight line vertically down. As demonstrated in this video, conduits such as. The term applies to a crossing in which a pilot bore is drilled, and then enlarged to the size required to accommodate the product pipe. Many times, a non-vertical well is drilled by simply pointing the drill in the direction it needs to drill. Directional drilling is used to install conduits under obstacles such as roads, buildings, and wetlands. ![]()
