PetrisWINDS Recall LOGSCAPE

PetrisWINDS Recall LOGSCAPE is a unique interactive tool for the visualization and manipulation of down-hole data. It provides interactive graphical editing and processing for all types of data stored in Recall. There is a range of input options and a toolbox of functions that can be combined into a specific user defined interactive application.

Any existing PetrisWINDS Recall curves and zones can be selected for input. Data can be entered numerically in tables or graphically using the mouse.

The control parameters are displayed in SuperView style screens which support selections, drag and drop, expansion and contraction, undo and redo, database inquiries, context sensitive help, and optional multiple window displays. Any control parameter is available from the parameter definition tree, pop-ups on the graphical display or separate "tear-off" windows.

PetrisWINDS Recall LOGSCAPE is able to instantly recalculate and redisplay curves as inputs and formulae vary. Functions are linked into complex processes, providing capabilities that include:

• Basic Data Editing including Despiking, Depth Shifting and Graphical Curve Splicing
• Log Filtering
• Interactive Petrophysics
• Hydrodynamic Pressure Analysis for interpreting Static Pressure Depth Measurements taken in different wells, with Borehole Breakout Analysis

Functions currently available include:

• Formula - Full C Syntax Arithmetic Expressions including the "?" Conditional Operator and the complete set of Math Functions, with Point by Point Graphical Value Editor
• Depth Range Reduction and Block Shift
• Variable Depth Shift based on Shift Curve
• Scale - sliders for scaling Curve Data Values
• Splice - one Curve spliced onto another
• Integration
• Differentiation
• Zoned Regression - transforms Depth Based Data to a piecewise Linear Regression Curve
• Digital Filter - Box, Triangle, Gaussian, [Deconvolution], [User defined], [Calculated]
• Statistics - Mean, Deviation, Min, Max, Point Values - transforms Depth Based Data to Constant or [Zonal] Data
• Comprehensive zoned cross-plot
• Dip tadpole plot
• Stereo plots
