12.3 Well Logs
|For Standard||RESQML v2.0.1|
From a RESQML perspective, well log curves are simply property values assigned on a sampling (a list of measured depths) defined along the trajectory (Figure 12.3-1). The list of measured depths is held in the wellbore frame representation, which corresponds to a WITSML well log.
The wellbore frame represents the wellbore interpretation, references the trajectory on which it is based, and defines a sampling where each node has a given measured depth. The sampling can be defined using either of these methods:
- Explicit list of values, which indicates aperiodic sampling.
- Lattice of values, which indicates periodic sampling.
The property values can be attached to either the nodes or the intervals of the sampling. For more information about properties, see 8 Properties .
