Potential Fields
Measuring Natural Field Variations
Potential field methods measure naturally occurring variations in the Earth’s magnetic and gravitational fields. These variations are influenced by subsurface material properties and structure, allowing broad-scale characterization without introducing energy into the ground.

When Broad Coverage Is Needed
In many settings, subsurface features extend beyond the resolution of localized investigation methods. Potential field surveys are used to identify large-scale geologic features, material contrasts, and structural trends that support regional understanding and guide focused follow-up investigations.

Field-Based Potential Methods
Potential field methods rely on passive measurement of natural Earth fields. These approaches are well suited for regional-scale investigation and are commonly used to support broader subsurface characterization efforts.
See Regional Patterns
Potential field methods provide regional-scale insight into subsurface conditions using passive measurements. These surveys support planning by identifying broad trends and guiding focused investigation where needed.
