B01.3 • Data hierarchy in an Emeraude document
Emeraude uses a hierarchical representation of the
data as opposed to a flat structure.
First in the hierarchy is the Document, i.e. data
whose definition is unique and will be used in the
different surveys and interpretations. In the
document, common information is stored as the
General Well Data
. Typically the General Well Data
will include (some of) the following: open-hole
Gamma-Ray, T.V.D. or deviation log, zoned I.D. or
caliper log, perforations, etc.
At the same level as the General Well Data level is
the
Survey
, i.e. a set of data/information pertaining
to a particular well condition. Several surveys may
be stored in the same document. The main Survey
data is the actual
Log Data
, consisting of passes
(
Up
and
Down
, and possibly
Stations
). Each pass
contains a series of measurements. Finally, survey
data provides the basis for one or several
Interpretations
. Multiple interpretations can be, for
instance, due to the existence of several tools of the
same kind (e.g. in-line and full bore flow meters).
The data hierarchy is mirrored by the 3 control panel
modes: Document - Survey - Interpretation. As will
be illustrated further, the data browser can be used
at any point in the session to get a hierarchical view
similar to that on Fig. B01.6.
