The Warrior Well Logging System employs advanced software and widely available hardware to provide a cost-effective solution to well logging requirements for both open and cased hole applications. Its main features include:

Multitasking  System Using Microsoft Windows 2000,or XP

The real time logging operation may be conducted at the same time as other tasks, such as data/fax transmission, plotting, log heading, job ticket preparation etc. The use of MS Windows ensures longevity, future enhancement and support for the system.

Graphical User Interface

The system is easy to use and the interface conforms to the popular MS Windows standard. Data monitoring is available in windows, which may be resized and repositioned as the user wishes. A typical user screen with scrolling log display and data monitors is shown below. 

The example shown at the left the operator is able to monitor the real time scrolling log, view any or all of the acoustic signals generated by a bond tool, and also monitor all the log outputs, including depth and line speed. Optionally raw sensor data may be displayed.

Multiple log plot windows may be opened for comparison of, for example, main and repeat log sections. Log plots may be paused and scrolled to any depth and annotations added, while data acquisition continues.

Depth correlation is achieved while logging, with the screen plot and system depth updated until correct depth is attained.

Log curve scales and other presentation parameters may be adjusted while logging and the screen plot redrawn until the desired output is obtained. The hardcopy plotter may be stopped and started at any time, presenting any interval with any desired presentation format.

PC ATX Based Computer

The system uses familiar and inexpensive IBM PC/ATX™ compatible components to reduce cost and provide worldwide availability of parts etc. The tool interface connects to the computer through the industry standard Universal Serial Bus (USB). The performance of the systems may be upgraded easily, as more powerful CPUs and other components become available. Configurations are available for rack mount, or notebook and other portable computers

Tool Interface and Power Supply

A compact tool interface and power supply may be provided which is suitable for the most downhole tools. The latest Digital Signal Processing (DSP) technology is employed to minimize hardware complexity and maximize flexibility. The interface may be configured for open and / or cased hole services, and incorporates expansion slots for development and upgrade.

Hardcopy Support

Generation of the final log print with heading, annotated log sections, calibrations, tool string diagrams, etc., is easily achieved. The system supports most well log plotter types currently in use, including color and the generation of multiple copies using fanfold paper. Two plotters may be driven concurrently and independently. The system also supports a fax format file as a plot output, which may then be transmitted, to a remote fax machine using a conventional fax modem.
