As much as 90% of the land surface of the earth is covered with loose, unconsolidated material. When drilling in so-called overburden, the conditions are often challenging with risk for collapsing walls, hole deviations, and failure to reach design depth or bedrock. The casing advancement system is comprised of an ingeniously simple method of drilling through overburden while advancing the casing into the hole at the same time. This enables contractors to perform their work faster with higher quality and reduced risk. The system adds value whether the mission is to install foundation, support elements, or simply case the hole in collapsing formation.
