Title: Use directional drilling to minimize number of wells drilled
Text: "Directional Drilling: Horizontal Drilling: Some productive formations are not thick but extend over a large lateral area. Prior to the advent of directional drilling, such formations were either uneconomical or required multiple wells to recover the resources. Modern technology allows wells to be drilled and completed in a relatively thin horizontal layer. A single horizontal well can contact more of the resource and therefore takes the place of several traditional vertical wells. Because the well bore interval from surface to producing formation is drilled only once, a horizontal well generates less waste than several vertical wells."
