SIG-701 HPR Tool

Reliable resistivity. Simplified design. Smarter decisions downhole.

Sigdrill's accurate and reliable resistivity tool

Advanced Measurement. Extended Performance.


Designed for the most rugged drilling environments, SIG-701 HPR Tool is unmatched in accuracy, drilling performance, and proven reliability. Its robust design delivers consistent results in the most demanding wells, helping minimize nonproductive time.


The HPR provides dual‑frequency measurements that perform across the widest range of formations and mud systems. With low power consumption, it extends downhole runtime, supporting up to 300 hours of operation with an eight‑cell battery powering both the HPR and MWD system.


The tool can operate as a standalone unit with onboard memory or in conjunction with an MWD system for real‑time data, making the HPR a reliable resistivity solution available through Sigdrill.
