4 PROCEDURE
4.1 Method
The method shown in the following flow chart identifies the process activities and controls. The notes provided herein give clarification and expand the detail explanation of the flow chart.
A. Prepare recording support
- Seismic Line sketch
- Shooting program list.
- SPS In file from MESA
- Map from topography
B. Prepare field equipment
- Layout FDU Link along the line seismic
- Planting geophone string every traces vertically and fully closed under ground
- Powered the LAUX/ LAUL by battery to drive the spread of FDU Link along the line spread
C. Prepare recording instrument
- Install each equipment (HCI, PRM, CM 408, Cartried drive, Camera plotter,
Master/ Slave controller, Radio communication, UPS and other peripheral) as factory procedure
D. Prepare shooting equipment
- Batteries have been fully charged
- Completely and ready for use firing Line and Uphole
- Radio blaster and its antenna completely
- Fishing steak and hue for open hole
E. Perform daily test
- NOISE Instrument test
- DISTORTION Instrument test
- GAIN/ PHASE Instrument test
- COMMON MODE REJECTION Instrument test
- FIELD IMPULSE test
- FIELD NOISE test
F. Production
- Maintain quality of data every record
- Make observer log (explanation and notation of anomaly record)
- Make chronology report of activity
- Create SPS out to be sent to mesa
G. Handling data from the field
- Both dual tape data covered by aluminium foil to protect field magnetic effect.
- Split both of dual data tape A and tape B, tape A today production and tape B yesterday production send to base camp, tape B kept to be sent tomorrow
- Use water proof bag for delivery data and supporting data to base camp to protect rainy water
4.2 RESPONSIBILITY
Responsibility for the activities associated with this procedure is shown in the flow chart.
4.3 RECORDS
Records resulting from this procedure are identified in the flow chart. The retention and archive periods for records is defined in FM.IMS.004 (Document Retention & Archive Periods).
