JAE

AE’s SMART DM is a ruggedized directional module designed for continuous downhole operation. Engineered for utmost quality & reliability, using JAE’s proprietary sensor technology, the SMART DM is a full-featured system. It has the ability to measure dynamic inclination and azimuth, multi-axis shock and vibration, and downhole RPM for optimized drilling performance. With the addition of an optional integrated Azimuthal Gamma Controller feature, the SMART DM is a “plug & play” solution for most current & legacy Directional Modules, while incorporating the latest technology.

SMART DM Key Features:

• 175°C Maximum Operating Temperature
• MCM Magnetometer Package
• Integrated Azimuthal Gamma Controller
• Dynamic Inclination and Dynamic Azimuth
• Real-time shock and vibration
• RPM Measurement and Stick Slip Indicator

he Azimuthal Gamma Controller works by correlating incoming gamma readings with the direction the sensor is facing (toolface) when the counts were received. The Azimuthal Gamma Controller feature can be added to existing SMART DMs and will work with most shielded gamma sensors to provide both real-time and recorded azimuthal gamma data.

Benefits and Features:

• Available as an upgrade to existing SMART DMs
• Accepts up to 3 gamma inputs (2 focused, 1 bulk)
• Compatibility with most gamma detectors
• High speed azimuthal binning
• High resolution recorded 16-bin azimuthal gamma data
• Configurable real-time parameters (U/D, Hot/Cold, 3 bin, 4 bin, etc.)
• No added length to the toolstring
• High temp reliability (utilizing the proven high temp reliability of the SMART DM)

Technical Specifications:

• 16 bin resolution (22.5 deg)
• Binning RPM:
  • Specification: +/- 150 RPM with +/- 1 bin error
  • Capability: +/- 400 RPM
• 255 CPS max for focused gamma
• 1000 CPS max for bulk gamma
• 2 µsec min gamma pulse width

Logged Parameters:

In addition to the regular SMART DM logs, the Azimuthal Gamma Controller logs:

• 16-Sector data
• Hot sector/Cold sector
• Binning toolface offset (updated after every survey)
