AIT Array Induction Imager Tool

As a component of triple- and quad-combo toolstrings, the AIT array induction imager tool generates resistivity logs from measurements made simultaneously at five different depths of investigation (DOIs)—10, 20, 30, 60, and 90 in. The differences between the curves enable accurately characterizing the shallow invaded zone and determining true resistivity, Rt, from deep measurements. The resulting dataset provides the minimum information required for basic formation evaluation answers, such as porosity and saturations.

This basic insight is readily expanded by combining the triple- and quad-combo data with additional measurements. Integrated interpretation employs advanced workflows, the multidisciplinary expertise of our interpretation geoscientists and engineers working with you as needed, and software such as the Techlog wellbore software platform to maximize the value of your logging data. The result is the fullest possible understanding of complex lithologies, such as carbonate, shaly sand, and shale reservoirs.
