ODEX/Eccentric equipment enables you to drill and case deep holes simultaneouslyin all types of formation, even those with large boulders.
The method is based on a pilot bit and eccentric reamer, which together drill a hole slightly larger than the external diameter of the casing tube. This enables the casing tube to follow the drill bit down the hole.
When using ODEX, part of the impact energy is diverted to the casing tube via a shoulder on the guide device, which in turn impacts a special casing shoe at the lower end of the casing.
