5. What is Symmetrix drilling?
Previously known in our industry as Concentrix, the updated Symmetrix system allows for the simultaneous casing and drilling of a hole. The system consists of three main components: pilot bit, ring bit (reamer) and casing shoe
6. What is overburden thickness?
Overburden are a source of water not only for dug wells or well points, but also for bedrock wells.
7. Why is overburden important?
In a petroleum system, the overburden rock overlies the source rock and contributes to its thermal maturation because of higher temperatures at greater depths. The age and thickness of the overburden rock determines the burial rate and thereby influences the heating rat.
