Specifications
Description
With azimuthal gamma, operators can see the dip and direction of the formation while rotating. By combining four gamma sensors into one probe, the Quad Orbital Gamma can capture Azimuthal gamma readings while sliding.
The Quad Orbital module will give a clearer, crisper image than previous azimuthal gamma probe designs because of the increased amount of sensor inputs. It is designed to be incorporated with the MWD tool string and replace the existing MWD gamma module.
Using PDT’s surface decoder, an 8-bin azimuthal gamma can be compressed downhole and decompressed on the surface for blazing fast decoding.
Applications
- Conventional Drilling.
- Vertical, directional and horizontal drilling.
- Unconventional Drilling.
- Coal Bed Methane/ coal seam gas.
- Mining/degasification and delineation of fields.
- Detecting Faulted Formations.
- Rotary inclination feature allows for continuous survey while drilling.
Features & Benefits
- Selectable between 2, 4 and 8 bin azimuthal gamma.
- Gamma can be sent to surface using conventional 1 bin at a time transmission or data compression methods.
- Ability to slide and still see up and down gamma.
- Off-centre detectors for higher contrast logs.
- More detectors for greater detection of small differences between each bin.
- Proprietary algorithms to reduce the shine-through from the shielded part of the detector.
- Memory recorded for post-processing.
- Rotary inclination.
- Shock and vibration.
- Conventional gamma.
- Downhole RPM.
- Works with BHA magnetic interference.
- Real-time transmission of tool status for ensuring proper tool operation.
