Column Name Short Name Data Type Data Precision Comments
DIRECTIONAL_SURVEY_LINE_ID DIR_SUR_ID NUMBER 10 DIRECTIONAL SURVEY LINE ID is the primary unique numeric identifier for a feature.
APPLICATION_DETERMINATION_NUM APPLCTN_DM VARCHAR2 9 APPLICATION DETERMINATION NUM is the number assigned to an approved or permitted activity or to a set of activities included in a multi-activity application, e.g., 100082189
WELL_AUTHORITY_NUMBER WA_NUM VARCHAR2 10 WELL AUTHORITY NUMBER is the BC well authority number.
DRILLING_EVENT_SEQUENCE DRILL_EVNT VARCHAR2 2 DRILLING EVENT SEQUENCE is the code indicating the chronological sequence of a significant drilling operation of a drill hole which yields a separate and unique set of geological or production data.
UNIQUE_WELL_IDENTIFIER UWI VARCHAR2 16 UNIQUE WELL IDENTIFIER is the unique well identifier which is the standard 16-character code which defines the bottom hole location and each significant drilling or completion event in the well.
GEOMETRY GEOMETRY SDO_GEOMETRY 1 GEOMETRY is an ArcSDE spatial column: coordinates defining the features.
OBJECTID OBJECTID NUMBER 38 OBJECTID is a required attribute of feature classes and object classes in a geodatabase. This attribute is added to a SDE layer that was not previously created as part of a geodatabase but is now being registered with a geodatabase.
SE_ANNO_CAD_DATA BLOB 4000 SE ANNO CAD DATA is a binary column used by spatial tools to store annotation, curve features and CAD data when using the SDO_GEOMETRY storage data type.
FEATURE_LENGTH_M FEAT_LEN NUMBER 19 FEATURE LENGTH M is the system calculated length or perimeter of a geometry in meters.
