1. An apparatus, comprising:
a downhole tool assembly, capable of supporting one or more tools, supplying power to the tools, and providing communications between the tools and surface equipment, wherein the downhole tool assembly is utilized within a borehole of a well system;
a first tool, mechanically, electrically, and communicatively coupled to the downhole tool assembly, wherein the first tool includes a first sensor oriented at a first azimuthal angle; and
a second tool, mechanically, electrically, and communicatively coupled to the first tool or to the downhole tool assembly, wherein the second tool includes a second sensor and the second sensor is oriented at a second azimuthal angle, and wherein the first sensor and the second sensor can measure one or more characteristics of a reservoir, and the downhole tool assembly derives a porosity anisotropy using the one or more characteristics.
