Open Hole Logging System

The Warrior Open Hole 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.

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.

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

In the example shown 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.

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.

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 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 220 VAC, 50-60Hz configurations.

There are 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 connectors 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.
