100

This part of the BaseStar tool houses the Pumps off Power module, Directional Module, PLC/NAS module, and PWD module.

What is the Sonde Assembly?

100

The method used by other next generation tools for buffering data into the BaseStar's NAS storage memory across the PLC Bus.
Data is variable and often much smaller.

What is Variable Data Burst Transfer?

100

This is a 22V smart component designed for next gen fleet of tools.

What is the iStar Battery?

200

This component serves as a temporary 15vDC power supply for periods where the pumps are off.

What is the Pumps off Power module (POP)?

200

This is called the SPI and it is another method used within BaseStar to interface various sensors and memory devices.

What is Serial Peripheral Interface (SPI)?

200

The BaseStar tool can also receive power from this component on surface.

What is SWRO?

300

This component provides static pumps off surveys and High Frequency periodic burst data in recorded memory. It also determines the orientation of the drillstring.

What is the directional module?

300

This is the legacy process of buffering data into a central location downhole, so it can be read at high speed on the surface.

What is Downhole Data Transfer (DHDT)?

300

This main power output powers the PLC PCB and everything in the Sonde Assembly ( NAS, DM, PWD, WOB/TOB, POP charging...)

What is 15VDC?

400

This component senses pressure changes in the wellbore.

What is the PWD module?

400

This allows multiple electronic devices to communicate with each other over a single bus.

One line is used as a serial clock line (SCL).

What is Inter-Integrated Circuit (I2C) Bus?

400

Battery consumption is tracked using this application vs manually calculating as it was with legacy tools.

What is iTom?

500

This part of the Basestar tool houses the Flow diverter, scribe line, SWRO, WOB/TOB Puck, Caliper/Imager, Pressure Sleeve, Gamma module, spacer ring, and locking sub.

What is the sensor collar?

500

This is the communication protocol and is very loosely based on MIL-STD-1553. It sends real-time data from other sensors on the PLC Bus back to the PLC/NAS in preparation for transmission.

What is Sperry Manchester 1553?

500

These are the type of cells used in the iStar Battery collar to maximize available energy.

What is 3.65v FAT D type cells?
