PRODUCT SPECS

The SurfaceTraC System, from Scientific Drilling, is the first of its kind to utilize a surface magnetic field source (with a GPS surveyed position) to accurately position the wellbore without cumulative uncertainty, and avoid collisions in a congested environment. Each ranging measurement, which is recorded while drilling, is referenced back to the surface field source and does not compound errors from previous stations. When operating in highly congested environments, the SurfaceTraC System is the ultimate solution for delivering optimally placed and cost effective shallow horizontal wellbores.

No additional downhole equipment is required, providing cost savings and safer operations

Ellipse of Uncertainty (EOU) remains the same at each survey point, eliminating a growing EOU and ensuring that wellbore placement in the producing zone is optimized

Significantly reduces the need for survey management, minimizing extra rig time, and eliminating additional costs

Ability to avoid collisions with vertical observation wells without the need to access the cased vertical well

System is ideally suited to confirm TVD of extended-reach horizontal wells, and to optimize spacing between horizontal wellbores

Utilizes a GPS surveyed position at surface for high-accuracy wellbore placement

Ability to be installed on short notice for greater efficiency
