Horizontal drilling is a technique used in the oil and gas industry to access resources located deep underground. Unlike traditional vertical drilling, which goes straight down, horizontal drilling allows the drill to extend horizontally once it reaches the desired depth. This method enables access to a larger area of the resource, making it more efficient and cost-effective. By using horizontal drilling, companies can extract oil and gas from formations like shale more effectively. This technique has revolutionized the industry, leading to increased production and reduced environmental impact. It also allows for drilling multiple wells from a single location, minimizing surface disruption.
