Warrior Cased Hole Well Logging System

        The Warrior Well Logging System employs advanced software and widely available hardware to provide a cost-effective solution to well logging requirements for open and cased hole applications in SRO, LWD and memory operations.

Its main features include:

Wide Range of Down Hole Tool Support

Scientific Data Systems supports the widest range of down hole tools from many manufacturers. Tools in current production and obsolete equipment are supported.

Ease of Use with 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.

In 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 maybe 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.

Windows PC Computer

The system will run on almost any Windows computer. 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. Systems may be configured 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 down hole 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 future developments and upgrades.

Plotter 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 pre-folded paper. Two plotters may be driven concurrently and independently. The system also supports PDF and other file formats as plot output.

Standard Cased Hole Panel CPF

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

        Faceplate dimensions are 19” by 7”. Chassis is 17” by 17” by 7”, cable connections require another 2 to 3 inches of rack depth. The approximate weight of the panel is 45 pounds.

        The rear of the standard interface panel is shown below. The encoder connection is a 7 pin Amphenol connector with a fused encoder power. The 5 pin pressure transducer is wired for a 4-20ma input, but modifications can be done to accept a 0-10 VDC input. The panel is available in 120 VAC or 220VAC , 50-60Hz configurations.

        Shown are the 5 USB ports from the internal USB hub with strain relief clamp for the USB input from the computer. The passive CCL from an external shooting panel is brought into BNC CCL jack. The line connection can be made to either a BNC or a RG-59 UHF connector. There are two 4-20ma 5 pin connecters that can be used for well head pressure or grease pump pressure. There is a DB-25 connector with connections for up to 5 ADC inputs and 2 TTL counter channel inputs.
