X-Series Triggering Excellent Results
11th April 2017
Geochain’s 2016 X-series upgrade has now completed several successful surveys around the globe. In Q1 2017, a large, independent E&P company completed a slow rate pumping flood analysis of previously fracced high temperature (320F+) wells in South Texas, USA. To achieve this, the company used ASL’ s latest downhole 15-level X-series Geochain recording system passively sampling at a 250us interval. The purpose of such surveys are to differentiate and identify fluid migration rates through the local geology, which in term gives crucial information for the viability of secondary/enhanced reservoir recovery.
Historically, microseismic surveys monitoring slow rate pumping do not typically see many events, yet low noise AS272 gapless recording X-Series upgrade system combined with the high sensitivity Quad AS227 Omnidirectional sensor pack triggered 1000’s events over a short time period.
The X-Series upgrade allowed the Geochain downhole monitoring system to deliver:
- Real time gapless monitoring within high temperature well environment
- 15 receivers sampling at 0.25ms interval
- 1000’s events triggered with clean base line and excellent P/S move out
- Clear head wave arrival detected
- No survey downtime
