RFQ:
1. What is an overburden well?
The overburden wells are usually composed of sands and gravels and they include those constructed into the geological materials that are above bedrock. Most water wells come with a well screen that lets groundwater into the well while keeping away sand and other materials.
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.
