Uses for Pavement Milling. Pavement milling has many uses. One of the main reasons to mill asphalt is to recycle the road surface, which is then ground up and used .Milling and ResurfacingAsphalt Milling. Asphalt milling by definition is the process of removing and recycling existing asphalt pavement in order to restore and correct any errors in the current asphalt surface. The first step in the process is to remove the top layer of asphalt in an area.

Historically, drillers have relied on openhole cement

ing operations. Traditionally, most openhole side-tracks are kicked off from a cement plug. These operations involve drilling a pilot hole and then setting a cement plug that extends several meters above and below the KOP. Once the cement has set, a directional BHA is used to kick off the well to begin drilling the sidetrack.
