Directional drilling has been used for a variety of purposes; utilities, dewatering, and remedial activities. Cutting costs for remedial activities it is always of consideration. What the costs are to clean-up a site via traditional vertical extraction wells versus using a horizontal well system needs to be reconsidered based upon todays remedial challenges. Traditionally, it has been stated that a single horizontal well is worth 3-11 vertical wells.
We evaluated the cost of implementing a Vertebrae™ horizontal nested well system versus vertical wells at a small site and a large site.
Because of the large number of site variabilities and cost uncertainties, we applied a Monte Carlo, or “random walk” simulation, to generate probability distributions for each case.
