Full title and description
Standard Guide for Conducting Borehole Geophysical Logging: Mechanical Caliper — a concise ASTM guide describing procedures, calibration, documentation, and interpretation considerations for mechanically based caliper logging (spring‑loaded arm calipers) used in geologic, engineering, groundwater, and environmental borehole investigations.
Abstract
This guide defines caliper logging as a record of borehole diameter with depth and explains the purpose, typical applications, limitations, and recommended supporting practices (including use in conjunction with Guide D5753). It covers general procedures for conducting caliper logs in boreholes, wells, access tubes, caissons, and shafts; recommended calibration and standardization practices; documentation and log quality considerations; and interpretation guidance focused on geotechnical investigations.

Scope
This guide covers the general procedures necessary to conduct mechanical caliper logging of boreholes, wells, access tubes, caissons, and shafts as commonly applied to geologic, engineering, groundwater, and environmental (geotechnical) investigations. It excludes caliper logging for mineral or petroleum exploration and development. The guide is restricted to mechanically based devices with spring‑loaded arms and is intended to be used in conjunction with Guide D5753 for planning and broader geophysical logging programs.
Key topics and requirements
- Definition and purpose of caliper logs: recording borehole diameter with depth for interpretation and borehole completion planning.
- Recommended equipment: mechanically based calipers (single‑arm or multi‑arm spring‑loaded devices) and considerations for probe selection and handling.
- Calibration and standardization procedures to ensure accurate diameter measurements and reproducible logs.
- Documentation and data quality: logging protocols, depth control, environmental and borehole conditions, and metadata to accompany caliper logs.
- Applications and limitations: use for packer placement, calculation of borehole volume, casing/annulus planning, lithologic correlation, and recognition of borehole enlargements or collapses; not a substitute for professional judgment.
- Units and reporting: SI units are primary; inch‑pound conversions may be provided for convenience.
Typical use and users
Used by geotechnical engineers, hydrogeologists, environmental consultants, well constructors, site characterization teams, and borehole logging service providers to assess borehole diameter, shape, roughness, and stability; estimate required completion materials; locate packer seating zones; and support interpretation of other borehole geophysical logs. The guide supports routine field logging, quality control, and reporting for geotechnical and groundwater investigations.
