Multicomponent Theory
Pressure, fluid content, clay content, all affect this.
Velocity of the propagating wave
The Z component is recorded by this kind of receiver
Geophone
These two headers are important to read in for OBN data
Tilt and rotation
This is the literal that stores the component types (P,Z,X, and Y)
FIELD_SENSOR_TYPE
This process simultaneously accounts for the various timing delays or acquisition perturbations observed in data.
SWC process
This type of wave spent part of it's travel time as a compressional and shear wave
Converted wave
The combination of X and Y components are called this kind of deliverable
Radial
This phrase could describe the problem when reading OBS data from contractors
lack of standardization
This is the number that is stored in DATA_TRACE_TYPE for Z data
333
These two processes need to be applied to data before running the timing QC workflow.
Nav Merge and Source directivity correction
This type of anisotropy is the same as Traverse isotropy
Polar anisotropy
This domain is most often used for OBS data
Receiver
OBN processing startup template
The reflectors on these components of data appear later in time than on the Z component
X and Y
This type of data variation is affected more in deep marine environments than shallow water.
Water velocity
This type of receiver measures pressure
Hydrophone
This is the type of acquisition when the source lines are parallel to the receiver lines
Inline OBS survey
This document(s) will help with starting to read in contractor nodal data
Best practice
This combination of data order indicates that the OBS data is sorted by reciever
DETECT_LINE_ID/DETECT_POINT_ID/SOURECE_POINT_ID
This kind of drift is a phenomena that is unique to this kind of acquisition.
Clock drift
This type of receiver measures directionality of a wave
Geophone
This is the kind of acquisition that has a sparse grid of receivers and a dense carpet of shots
Sparse node acquisition
This phenomena is unique to nodal data and describes when a node's clock doesn't match a reference clock
Clock drift
This component doesn't have bubble energy
Z
This type of energy appears stronger on OBS data than towed streamer data.
Bubble energy
