RFQ:

1. 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

2. 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.

3. Where do they put overburden?

The most common use for the large volumes of overburden produced by a surface mine is to remediate and

reclaim the area where it was first removed. Putting the sand, rock, and clay back where it came from helps

rebuild the level of the soil so that plant life can return.
