Budget estimate

$12,000 – $30,000

The budget for this contract can be estimated based on the estimated quantity of the chemical to be supplied. The document mentions that the estimated quantity is a monthly delivery of 250-750 gallons to four well sites. Assuming an average monthly delivery of 500 gallons and a price range of $2-5 per gallon, the total annual budget could be in the range of $12,000 to $30,000. However, this is a rough estimate and the actual budget may vary depending on the bid price and other factors. The contract may also be renewed or extended, which could increase the total budget. Therefore, the estimated budget range is $12,000 to $30,000 per year.
