350 | 650 | 1200 Series Pulse Generators: A Comprehensive Telemetry Solution for Every Wellbore
The Challenge of One-Size-Fits-All Telemetry
Using an incorrectly sized or spec’d pulse generator leads to:
⚠️ For Small Collars (e.g., 350 Series): Over-sized pulsers causing excessive pressure drop and restricted flow.
⚠️ For Standard Collars (e.g., 650 Series): Under-powered pulsers with weak signals in deep or noisy wells.
⚠️ For Large/HPHT Collars (e.g., 1200 Series): Standard pulsers failing under extreme temperature and pressure.
⚠️ Fleet Management: Inconsistent performance and maintenance across different tool sizes.
Our Series Solution Delivers:
✅ Optimized Fit: Each series is engineered for a specific drill collar OD range and performance envelope.
✅ Scaled Performance: Consistent signal strength and reliability across all sizes.
✅ Common Platform: Shared electronics and principles reduce training and spare part complexity.
✅ Right Tool for the Job: Ensures optimal telemetry performance from slim-hole exploration to ultra-deep HPHT wells.
