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.
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.
