The total value of the contract can be estimated by summing up the bid prices for each well reference. The total bid price for Granite Oilfield Services is $3,675.00 + $3,675.00 + $3,150.00 + $7,791.00 + $4,200.00 + $4,725.00 + $5,250.00 + $6,300.00 + $21,000.00 + $5,250.00 + $5,775.00 + $4,200.00 + $5,250.00 + $4,200.00 = $84,997.00. Additionally, the contractor will be paid for T/M disposal charges at cost, which will add to the total contract value. Assuming an average T/M disposal charge of $1,000 per well, the total T/M disposal charges would be $17,000. Therefore, the total estimated contract value is $84,997.00 + $17,000 = $101,997.00.
