ODEX is an excellent option when unconsolidated formations are too dense or cobbly for
Auger Drilling. ODEX is a down-hole air hammer system that is designed to advance
casing during drilling. Once a desired depth is reached they eccentric bit can be retrieved
leaving the casing in place for sampling or installations.
Features
Rapid removal of cuttings; High penetration rate, especially in resistant rock formation;
Easy soil and groundwater sampling during drilling;
Possible to measure yield estimate at selected depth in the formation;
Advantageous in unconsolidated formations with a high risk of caving
Eccentric Overburden Drilling System Consist of Guide device, Casing shoe, Reamer, Pilot bit, Guide sleeve and Locking kits
