Multi-Well Salt Solution-Mining Intercept

Kansas, USA · 2023 – ongoing

A repeat salt solution-mining program, connecting five-well sets from a single access well via coiled-tubing ranging-while-drilling

The challenge

→A regulator required positive well-to-well intersection instead of hydraulic fracturing.
→Each set: five vertical salt-solution wells in a line, connected below the casing shoe (~450 ft TVD).
→Shallow, high-dogleg geometry into narrow 3–11 ft TVD windows, with no target-well surveys.
→The result had to be repeatable across successive well sets, year over year.

Our solution

Torped™ rotating-magnet ranging on a coiled-tubing ranging-while-drilling unit: a single access well lands shallow, then drills the line, ranging to and intercepting each target well below the shoe. The first set pioneered a formation-current-injection AMR-while-drilling field test; composite-survey shift corrections steer each pass-by and intercept.

Repeat program: first set (2023) → third set (2025); a fourth planned for 2026

The result

3 well sets

connected (2023–2025); a 4th planned for 2026

·First-of-its-kind formation-current-injection AMR-while-drilling field test
·Each set links five vertical wells from one access well, no hydraulic fracturing
·Detected and corrected real survey shifts (e.g. +1.7° azimuth; up to ~27 ft) in real time
·Hydraulic communication confirmed; missed wells re-aligned by sidetrack
