Municipal Water Restoration, Horizontal Intercepts

Midwest City, Oklahoma, USA · 2025

Five horizontal laterals intercepting a 16-in. municipal water well, production restored from ~100 to ~1,200 GPM

The challenge

→A municipal supply well had declined to ~100 GPM (0.38 m³/min), no longer meeting community demand.
→Rehabilitate the existing 16" (406 mm) steel-cased well rather than replace it and its surface facilities.
→Constrained urban site with shallow, unconsolidated sand (~340 ft TVD) demanding aggressive trajectory control and repeatable through-and-through casing intercepts without compromising integrity.

Our solution

Torped™ at-bit rotating-magnet ranging integrated with coiled-tubing drilling: a ranging sensor ran inside the existing vertical well while a rotating magnet on the BHA was detected through the casing, and the composite survey workflow refined the placement of each lateral approaching its intercept. The coiled-tubing assembly built angle aggressively (doglegs exceeding 35°/100 ft) within the shallow sand, and CleanCut™ casing-entry milling established hydraulic communication on each intercept.

Production restored from ~100 GPM to ~1,200 GPM, full municipal service capacity

The result

~1,200 GPM

restored output, up from ~100 GPM (~12× the declined rate)

·Five successful through-and-through casing intercepts into the 16" cased well
·Coiled-tubing drilling built angle at >35°/100 ft in shallow unconsolidated sand (~340 ft TVD, up to ~1,700 ft MD)
·CleanCut™ milling cut clean apertures through both sides of the casing
·Hydraulic communication visually verified by downhole camera
·Service restored without replacing the well or its treatment and distribution facilities
