Logging/downhole measurements program:
|
Triple combo including MTT to determine borehole condition and temperature, and to identify intervals for positioning VSI.
Order of following tool strings to be determined by timing of operations, so that VSP is conducted during daylight hours.
Sonic tool string
VSI tool string for zero-offset
VSP
MSS tool string, time and temp permitting |
