Advantages
1. Applicable to weakly stable layers: The eccentric design can provide better wellbore stability and casing guidance in loose, porous, and easily collapsed formations.
2. Fast construction speed: Some processes allow direct completion of drilling and casing installation without mud construction. So that greatly shortening the construction period.
3. Reduce wellbore friction: The eccentric casing forms irregular contact in the wellbore wall, which can reduce the overall friction of the wellbore.Thereby reducing the lifting load of the equipment.
How to buy?
If you want to buy odex drill bit, you need to tell us the OD and the wall thickness of the casing you need. We also need to know the hole diameter, the Min. ID of the casing shoe, and the model of hammer.
In general, you need to choose the most suitable eccentric casing system according to the specific geological conditions, and also construction environment, economic budget and technical requirements to ensure the safe and efficient progress of the project.
