Notes:
1 10 ft. added to core hole depth.
' Assume 6.25 -inch diameter drill hole = 0.213 ft.3/ft.
3 An 80 Ib bag of Sakrete will fill 0.6 ft3. Assume $6.00/ 80 lb. bag, which equates to $10.00 per cubic foot of hole.
4 Cement and plug labor costs: Assume 2 hours per hole at $350 per hour (current rig, operator and helper rate).
5 Assume drill pad disturbance is 100 feet by 100 feet.
6 Assume D7 SU productivity of 400 Lcy's/hr at $175 per hour
Utilize a D7 SU tracked dozer. Assume 2 hours per pad at $175 per hour with operator
6 Assume average access road width to be reclaimed 15 feet.
9 Assume D7 SU productivity of 300 Lcy's/hr at $175 per hour with operator
10 Assume D7 SU productivity of 200 Lcy's/hr at $175 per hour with operator
11 Current cost for seed mix is $30 per acre.
12 Assume seed application will take 1 hours at $100 per hour for laborer and pickup.
13 Assume 50% failure rate reseed at $15 per acre.
14 Assume seed application will take 1/2 hours at $100 per hour for laborer and pickup.
