what is limits of AIV sand zone

Question

Accepted Answer

AIV sand zone limits refer to the maximum allowable acoustic impedance variation in sand formations.

AIV sand zone limits are determined based on the type of sand formation and the surrounding rock formations.
The limits are set to prevent damage to wellbore equipment and ensure safe drilling operations.
For example, in some formations, the AIV limit may be set at 20% while in others it may be as low as 5%.
AIV limits can also vary depending on the depth of the well and the pressure and temperature conditions.
It is important for Civil Quality Engineers to be familiar with AIV sand zone limits and ensure they are adhered to during drilling operations.
