NeuraLog - Automated Digitizing, LAS Editing and Quality Improvement

NeuraLog’s simple interface, driven by workflow wizards and automation, makes is easy to get your work done quickly. Automated depth gridding and curve tracing expedite this once tedious task of capturing log data. However, this is only part of the power of NeuraLog. Image warp/stretch are corrected by internal algorithms calculated from the log’s grid model. Real-time visual verification is achieved, as the curve trace directly overlays the image original. Once curves are traced, a log quality index value is computed, giving you an indication of the quality of each curve as well as total log quality. Curve calculations are available for basic log petrophysics, and curve mathematics allow you to depth shift or perform inverse operations. Finally, LAS data accuracy can be confirmed with our Virtual Light Table. Without these critical steps the quality of your data, and subsequently your analysis, is unknown. In short, NeuraLog allows you to verify and edit your log data on the fly to produce the best possible results.

Automated Tracing - Neural Network Speed and Accuracy drive tracing algorithms for better-than-human tracing with highlighting of the curves for immediate feedback. Both Solid and Dashed curve tracers are available to account for curve crossings.

• Built in grid model to account for curves crossing the grids
• Auto-stop error detection
• Interactive curve editing with immediate resume tracing

Interactive Log Display - NeuraLog displays your log raster image and traced curve vectors directly on the computer screen, providing immediate feedback.

• Point and click interaction with the tracing tool
• Scrolling and zooming
• Error correction at any point in the tracing process
• Automatic scrolling through log during curve trace

Image Warp and Stretch Correction - NeuraLog corrects for warp and stretch, a common problem in poor log images, automatically from depth grids to produce quality log images and digital data.

Multiple Curves and Tracks - NeuraLog provides the flexibility of defining multiple curves per track and multiple tracks per log.

Unlimited Backup Scales - NeuraLog’s automated tracing functions work on unlimited backup scales, automatically patching together the different sections of curve for streamlined curve output.

Quality Improvement - NeuraLog includes a comprehensive set of tools to improve the quality of your log data. The Log Quality Index (LQI) provides an overall measure of Quality Score of in-house or vendor data. The NeuraLog Quality Improvement tools include checks for pixel overlay, spikes, gaps, and depth gridding and guide you through the log to correct detected errors and improve the LQI score. Once this verification/correction is complete, the results are reflected in the LQI for an indication of the quality of your data.

For verification of LAS the Virtual Light Table shows the match between the log image and digital data overlay quickly and visually. The LAS data statistic report generator summarizes your data to check for norms with the LAS Validator. NeuraLog’s mission is to make sure that you have the quality data you need to get the results you want; raising the data standard is important to the industry and to you.

Multiple Runs/Curve Splicing - NeuraLog provides the option of merging multiple runs of the same curve within a log into one LAS file. In addition curves from multiple files may be merged into a single LAS output.
