NeuraLog Automated Well Log Digitizing and Preparation of Log Data

NeuraLog transforms scanned well log images into usable digital data. Neural-network-driven automated tracing streamlines the digitizing workflow, and built-in curve editing, quality control and validation tools let you correct and verify the data to meet your standards.

A raster log is simply a scanned image of a paper log, while a digital log contains the actual curve values stored as numeric data. Because the data is digital, software can perform calculations and analysis and generate customized displays and plots. The industry's most widely used digital log format is LAS (Log ASCII Standard). NeuraLog transforms raster logs into digital logs.

Artificial Intelligence Log Feature Extraction (AILFE) helps identify and isolate curves, grids and background elements within well log images, and AI-powered OCR helps capture well log header information.

Windows 11 recommended (Windows 10, version 1903 or later), an i5 processor, 8 GB+ RAM, 2 GB video memory, 500 MB disk space and a 1920×1080 screen. For AILFE, a dedicated GPU with 4 GB+ VRAM is recommended, with a modern 64-bit Intel or AMD dual-core processor (2013 or newer).

NeuraLog exports LAS (versions 1.2 and 2.0), PETRA ASCII well data and PETRA Log Image Calibration (ILC) files. Multiple runs of the same curve, or curves from several files, can be merged into a single LAS file.

Yes. NeuraLog is designed to work with large, high-resolution raster log images. Performance depends mainly on available system memory, processor speed, storage performance and image size. Large files can be viewed, digitized and quality checked without splitting them into smaller sections.

NeuraLog does not impose a practical limit on raster image size beyond available system resources. As computer hardware improves, NeuraLog can take advantage of additional memory and processing power to work with increasingly larger image files.

Yes. NeuraLog allows multiple raster logs to be opened at the same time, making it easy to compare logs, review different wells or work on several digitizing projects concurrently.

Yes. Multiple log windows can remain open simultaneously, so you can reference one log while digitizing or reviewing another.

NeuraLog provides several navigation tools, including a thumbnail view, keyboard shortcuts, zoom controls and rapid scrolling features that let you move through long raster logs efficiently.

Thumbnail View provides a miniature overview of the entire log image, so you can jump to any depth or section by selecting it instead of scrolling manually through the entire document.

Yes. NeuraLog includes keyboard shortcuts to move through large images, zoom in and out, and switch between viewing modes, significantly reducing the time spent navigating long logs.

Pressing the Space Bar moves the cursor location to the center of the screen, so you can quickly navigate in any direction without using scroll bars. This is particularly useful when inspecting long well logs for quality control and digitizing review.

Yes. NeuraLog can calculate conductivity from resistivity curves and create a new output curve, while preserving the original resistivity measurements. NeuraLog can also calculate resistivity from conductivity curves.

The Light Table overlays the digitized curves directly on top of the original raster log image. This makes it easy to verify visually that the digital data follows the original curves and to identify any areas that need correction.

The Light Table provides immediate visual confirmation of digitizing accuracy. Instead of comparing numbers or plots separately, you can see exactly where the digital curves align with the original log and quickly spot tracing, depth or scaling issues.

Yes. The Light Table is designed for quality control. By comparing the digital output to the source image, you can easily identify misaligned curves, missed sections, spurious traces and other digitizing issues.

Yes. NeuraLog provides automated quality-control checks that help identify common issues such as gaps, spikes and other anomalies that may affect the quality of the final digital log.

NeuraLog identifies potential issues and directs you to the affected areas for review. You can then quickly verify and correct any problems before finalizing the digital log.

Yes. QC checks can be run throughout the digitizing process, so you can verify corrections and ensure the highest possible data quality before delivery.

The Quality Index Report provides an objective assessment of digitized log quality. It summarizes potential issues identified during digitizing and helps you evaluate the overall reliability of the digital output.

The report directs you to areas that may need attention, reducing manual review time and helping ensure that the final digital data accurately represents the original log.

Yes. The Quality Index provides a consistent measurement for comparing digitizing quality across projects, so you can quickly identify logs that may need additional review.

Not necessarily. A lower score typically indicates that the source image or curve conditions presented challenges during digitizing. The report helps you identify and review those areas before finalizing the data.

Before delivering or exporting final data. It provides a final quality-control checkpoint to help ensure confidence in the resulting digital log.
