WELLCAD for Win32

WellCAD for Win32 is a professional desk top solution for well data management and processing. It is now OLE2 compliant (as both an OLE client and server) making it more powerful and flexible as a data repository and geophysical and geological reporting tool. Work within the Windows environment using OLE and clipboard facilities to seamlessly exchange data between WellCAD and other OLE compliant applications. Batch processing and printing may be speeded up by macros created using WellCAD and OLE Automation.

WellCAD handles most data types associated with a borehole on a single worksheet. Import, Edit, Process, and Report functions are available for conventional wireline logs, full wave sonic logs, formula logs, mud logs, lithological logs, comment logs, engineering logs, structure logs, image logs, 3D logs, and OLE logs (bitmaps and other OLE objects). Now available as a separate module is the Image and Structure processing module for interactive image log interpretation and orientation.

ALADIN/GeoBase

ALADIN/GeoBase is a modular Well Logging software package. The software is suitable for well logging and borehole seismic (VSP). The main features are calibration and operation of downhole instruments, real time data acquisition, data handling, graphical data display and storage of the data on disc or DAT in industry standard formats.

WinAPlot

WinAPlot is a Well Log plotting software. Logging data can be prepared for continuous plotting with a user friendly Windows style Graphical User Interface. The data can be previewed on screen (WYSIWYG). The software includes: Film header, Well sketches, Tool sketches, Curve Labeling, Curve Annotations, Free Annotations, VDL and waveform plots, Image plots, Lithology and Stratigraphy Columns, Fill patterns etc.

LogEdit

LogEdit is a program to edit digital logging data. Logging data can be loaded and in total or only as individual curves edited with following functions: depth shifts, multiplicative factors, additive factors, filtering, re-sampling, curve renaming, unit conversions, merge and splice.

PC-DLIS

PC-DLIS is PC software to read and write DLIS data. Conversions from and to LAS/ASCII or LIS can be performed.

RtEvrest - a complete and powerful Resistivity Forward Modeling Software

RtEvrest is a fast forward modeling software package for open hole wireline (WL) and logging-while-drilling (LWD) resistivity tools.

RtEvrest supports a comprehensive range of resistivity logs: old ES logs (N16, N64, L19), Russian BKZ logs (AMN, NMA), Laterologs (DLL, SFL), Induction logs (6FF40, DIL, ID/IM), 2MHz-LWD logs (compensated or not).

When used to compute synthetic resistivity logs as result of modeled tool responses, RtEvrest provides objective quality control of estimated Rt models, checks consistency of quick Rt inversion solutions, highlights anomalies or complex zones requiring further analysis.

When used in an iterative loop and in an interactive manner, RtEvrest provides an efficient way to locate bed boundaries (particularly for thin beds) and to overcome simultaneously different environmental effects altering resistivity measurements. The most common effects taken into account are: borehole shape, drilling muds  (very conductive to non-conductive), shoulder bed resistivity contrasts, invasion (flushed zone, transition zone or annulus), resistivity anisotropy, dielectric constant properties (for LWD). 

Therefore RtEvrest allows to provide higher quality resistivity models, from which are derived more accurate water saturation profiles in hydrocarbon-bearing formation.

RtEvrest uses the Log ASCII Standard (LAS) format as input/output files. The current software version is operating in the assumption of a "2D axisymmetic resistiviy model". (A "3D model" is under development.)

RtEvrest is available through different logging tool packages adapted to the users needs: predefined tool configurations at attractive prices or personalized configurations for specific use.

AUTOMATED MUDLOGGING SYSTEMS

AUTOMATED MUDLOG SYSTEM (AMS)

The AMS system is designed to streamline the gathering, manipulating and presentation of data which is typically gathered by mudloggers and wellsite geologists. The approach is graphical and intuitive. Drilling rate, lithology, total gas, gas components and sample descriptions are presented depending on users preference. Input to the AMS system is by either manual input, ASCII files or conversion of analog signals directly from sensors. Color presentation based on availability of color hardcopy output devices. The system outputs typical English and Metric logging scales (10, 5, 2.5, 2 and 1 per 100 feet). LAS file output of all data gathered is provided. A data telemetry module using cellphones or INMARSAT is available.
