Quick Answer
The cost of a drilled well can range from $15 to $50 per foot, depending on the location, geology, and equipment used, making the total cost for a well depth of 100-200 feet around $1,500 to $10,000.
Well Depth and Cost Relationship
The relationship between well depth and cost is straightforward: the deeper the well, the higher the cost. A well with a depth of 100 feet can cost between $1,500 and $3,000, while a well with a depth of 200 feet can cost between $3,000 and $10,000. However, it’s essential to note that the cost per foot decreases as the well depth increases, making deeper wells more cost-effective in the long run.
Drilling Techniques and Costs
The drilling technique used can also impact the cost of the well. Rotary drilling is the most common method and typically costs between $20 and $40 per foot, while percussion drilling costs between $15 and $30 per foot. Auger drilling is another option and can cost between $10 and $20 per foot. The cost of drilling also depends on the type of equipment used and the expertise of the driller. For example, using a small drilling rig can cost less than using a large, high-capacity rig.
