Drilling through formations with loose, unconsolidated material always comes with problems such as the bore hole caving in or collapsing. How to avoid these problems?
With years of field practice and research, Maxdrill has developed its Eccentric casing system applicable for strata with siltz sand or small-sized pebbles. With its simple structure, easy operation and reliable performance, this system can advance the casing easily for depth within 30 meters, and it is retrievable with long service life.
