Question

In construction of gravel packed wells, the pack-aquifer ratio is generally defined as __________.

• A. 50% of the size of gravel pack
  50% of the size of aquifer
• B. 60% of the size of gravel pack
  10% of the size of aquifer
• C. 50% of the size of aquifer
  50% of the size of gravel pack
• D. 60% of the size of aquifer
  10% of the size of gravel pack

Hint:

In gravel packed wells, the balance between gravel pack and aquifer is important for maintaining flow and filtration characteristics.

Answer 1

The Correct Option is A

The pack-aquifer ratio in the construction of gravel packed wells typically ensures that there is a balance between the gravel pack and the aquifer zone for optimal flow and filtration. A general rule of thumb is that the gravel pack and aquifer size are set at approximately equal proportions to maintain sufficient permeability and support for the well structure. Therefore, the correct ratio is typically defined as 50% of the size of the gravel pack and 50% of the size of the aquifer, making option (A) the correct choice.
