COST/BENEFITS OF HORIZONTAL WELLS

Cost/Benefits Of Horizontal Wells Disadvantages of horizontal wells are: 1. High cost as compared to a vertical well. In the U.S., a new horizontal well drilled from the surface, costs 1.5 to 2.5 times more than a vertical well. A re-entry horizon-tal well costs about 0.4 to 1.3 times a vertical well cost. 2.
