CLAS®

Graphical features

Easy and Powerful Logplot

• Log curves, with shadings and transparency.
• Dipmeter plots.
• Symbols with fixed or log curve dependent size.
• Color plots (Variable density based on log curve values).
• In-Logplot instantaneous log curve editing for Depth Shift, Patch and Baseline corrections

Multi-Well Crossplots

• Multi-Well, Multi Y-axis, Z-axis by color based scales.
• Symbol and color can be defined by well or Y-axis log curve.
• Matrix lines and multiple n-Exponent Regression.
• Draw polygons to export points or create Flag log curves.

Added interactivity

• Logplot and Crossplots are connected. Cursor movements on Logplot or Crossplot identifies nodes and log curves on other windows.

Histograms

• Multi-Well, Multi-Log Curve Histograms with transparency.

Petrophysics

• Shaly Sand intepretation
• Water Saturation, Clay Volume, Porositiy, Trend Curves
• Reservoir and Net Pay calculations with TVD correction.

Geophysics

• Compute velocity curves to work with wells in Time domain (Dix, Miller, Minimum Squares).
• Store the values as OpendTect Time/Depth model directly.

Editing tools

• Tabular editor to view/edit log curves sample-by-sample, Depth and Value.
• In-Logplot graphical Patch, Baseline corrections and Depth Shift.

Calculations

Precise True Vertical Depth computation for TVD, Northing and Easting.

Math Editor

• Run user defined formulas over logs.
• Use simple or complex unlimited conditions for If-Then-Else.
• Inputs can be Log Curves, Fixed Values or Variables.
• Variables can be assigned to Log Curves, Fixed Values, or other Formulas.

Data Management

Las Import

• Simple (fully automated) and Advanced LAS import (full user control).
• Imports Well Header and Run information.
• Multi-Well LAS Import with automatic well selection/creation. Import hundreds of LAS files with one click.

Flexible sampling

• Support for regularly sampled and unsampled data (like Core and Dipmeter)
• All curve output calculations can be computed with any constant or variable sampling rate.

Unit aware

• Detects, handles and converts measurement units.
• Allows undefined units for flexibility.
• Predefined units and conversions.
• User definable units and conversions.
