CTRWD™
Real-time magnetic ranging inside a fully pressure-contained coiled-tubing drilling assembly.
CTRWD embeds active magnetic excitation in a coiled-tubing BHA, turning ranging from a discrete wireline intervention into an integrated drilling function, with full pressure-control integrity maintained throughout convergence and intercept.
Designed for proximity-dependent operations where positional uncertainty and consequence are elevated, CTRWD delivers deterministic distance and directional updates to the target while the well stays fully pressure-contained.
Excitation, detection and telemetry are integrated within the coiled-tubing BHA, so ranging continues with no dedicated trips and no wireline entry into a live well, sustaining drilling momentum through convergence.
Higher injected current (~2× wireline) and increased electrode surface area strengthen casing excitation and improve galvanic coupling, delivering a stable, high-fidelity magnetic response in oil-based, water-based and total-loss mud conditions.
