Abstract

This invention presents a new user interface for editing well log data using a guide line and an “Area of Effect” (AoE) around it. The AoE is shown as a shaded area with transparency. The guideline is drawn either as a freehand continuous line or as a segmented line with multiple dots or as a combination of both.

A new method and interface for visually editing log data.

Introduction

When recording or/and analyzing data, users are often faced with intervals where the results are wrong, or affected by bad measurements, environment effects, inappropriate processing parameters, etc. In this case, the users with sufficient expertise are able to manually correct this data and reproduce the related outputs that go with this data.

Selecting and editing the data that requires editing   can be a frequent task performed on many software/applications especially on well log data. This task is usually done by:

  1. Applying zonation (depth interval selection) graphically on data where the value will be modified. Or
  2. Directly modifying the value graphically by manipulating the data presented as curves.

These techniques have drawbacks on:

-          Need to define precisely the boundaries of zones (depth interval) to be modified.

-          Repetitive operations, example number of mouse click to be performed.

In this invention, we are aiming at providing a simple interface to allow the user to quickly edit or modify the data of interest using an appropriate guideline.  and save it with all the outputs that go with it.

Prior Art

In existing petrophysical software, the task of editing and manipulating the well log data graphically is performed by making zonation or redrawing the expected value or by drawing a guide line.

The guideline technique can be useful but existing software is using segmented line that introduces a lot of mouse click operations.

Summary of the Invention

This invention presents a new user interface for editing well log data using a guide line and an “Area of Effect” (AoE) around it. The AoE is shown as a shaded area with transparency. The guideline is drawn either as a freehand continuous line or as a segmented line with multiple dots or as a combination of both.

As an example, this technique has been proven to be very effective on editing sonic data which often suffers from environmental effects and inappropriate processing parameters. This method works best when the sonic slownesses (Compressional, Shear, Stoneley, etc) are overlayed over a slowness time projection and/or Slowness Peaks that are generated by the Slowness Time Coherence methods [Reference: Kimball]. When the Slowness peaks are present on the Depth log, then this method selects the dot that is closest to the center of the area of effect. When no peaks are present, or when the user decides to ignore the slowness peaks, then this method will pick the value of slowness associated with the maximum coherence within the area of effect.

After the data is edited, the user can trigger different actions by a mouse right-click. In the example above, once the user saves the e...
