Introduction

The tool is used in production logging operations to centralize the tool string in vertical, deviated and horizontal wellbores. The tool has three arms with a rugged roller at each pivot tip. Each arm is fastened on two slick joints to ensure the arms themselves are precisely centralized, and they work together to provide a persistent contact force. The carbide rollers substantially reduce wearing.

The 3-Arm Small-Diameter Formation Testing Probe / Pad is designed for efficient formation testing where compact downhole tools are essential. Its small-diameter structure helps support operations in restricted wellbore environments while providing a practical solution for collecting formation-related data.

During formation testing, reliable contact and stable measurement are critical for understanding downhole conditions. The three-arm configuration helps the probe engage the formation effectively, supporting consistent testing and reducing challenges caused by limited operating space. This makes the 3-Arm Small-Diameter Formation Testing Probe / Pad a useful choice for demanding wireline applications.

For oilfield service companies and logging contractors, the tool helps address common concerns such as difficult access, limited wellbore space, and inefficient formation data collection. By combining a compact design with practical testing performance, the 3-Arm Small-Diameter Formation Testing Probe / Pad supports more efficient workflows and clearer formation evaluation, helping professionals make better use of valuable downhole information.
