Abstract
Surface nuclear magnetic resonance surveys are a valuable technique for investigating hydrologic properties in saturated aquifers, in the vadose zone, fractured reservoirs, and in permafrost settings, to name a few. Standard field measurements typically consist of a coincident large transmitter and receiver loop; while this approach has benefits with respect to field deployment and a smooth depth sensitivity function in 1D, there are numerous advantages to a compact, multicomponent receiver. Here we discuss these advantages, focusing on the imaging kernel for inductive receiver loops in all three principal directions. Additionally, we describe the imaging kernel in three dimensions and show the added spatial resolution available by a mobile three-component receiver. This analysis provides a first step toward proper survey design for subsequent 3D inversion for hydrologic properties.
