Quanta Geo Inversion

From Quanta Geo Raw Measurements To Quantitative Images

Quanta Geo Inversion is an advanced processing taking as input measured amplitude and phase images; it outputs formation resistivity and standoff images. The combination of these images can be used to identify open features (fracture, vug, breakout) filled with resistive drilling fluids. Combining Quanta Geo resistivity with deep resistivity logs can characterize drilling fluid invasion process.

Plug-in Overview

Designed for the interpretation geologists and petrophysicists, Quanta Geo Inversion allows to process Quanta Geo data quantitatively. It takes as input measured amplitude and phase channels. Through processing workflow containing specific steps it generates high-quality quantified resistivity and standoff images for further interpretation in geology, geomechanics and petrophysics.

• 16GB RAM; 10GB free space on C: and 50GB free space on D: drive
• Multi-core processor; NVIDIA Quadro® mid-range card

Applications

• Analyze images for open fractures and other open features
• Analyze images for near-wellbore formation quantified resistivity values
• Analyze images for near-wellbore drilling fluid invasion indications
• Analyze images for borehole geometry and drilling induced stress indicators

Key Features

• Create statically normalized borehole resistivity images from Quanta Geo data
• Create dynamically normalized borehole resistivity images
• Create statically normalized borehole standoff images

Features

The Quanta Geo Inversion plugin transforms impedance values generated by the button electrodes of the Quanta Geo tool into borehole formation electrical image and geometrical standoff images. The processing produces statically and dynamically normalized images. The plugin integrates into the existing Techlog Wbi module as well as with other Techlog plugins such as Advanced Borehole Geology Suite.
