Flag definitions for lithology and hydrostratigraphy.
In all cases we give suggestions for how to fix the problem. However,
if you believe that the record is correct, but that the flag is
incorrect, please open an issue
and let us know what the problem is (which flag is incorrect and why)
and with which Well (well_tag_number
).
You can access this list in R at any time through the
flags
dataset.
Many of these refer to from
and to
fields
which are the
lithology_from_ft_bgl
/lithology_to_ft_bgl
and
lithology_from_m
/lithology_to_m
.
Flag | Description | Solution |
---|---|---|
flag_int_missing | Interval missing lithologic record | Check original paper log |
flag_int_overlap | Interval which overlaps with the next or previous interval | Check original paper log, or fix in GWELLS if obvious |
flag_int_gap | Interval which has a gap between it and the next or previous interval | Check original paper log, or fix in GWELLS if obvious |
flag_int_note | Interval at the start with to/from of 0/NA which marks possible notes made before the lithology records |
Check original paper log |
flag_int_overrun | Interval (not at the start) that has a depth of 0/NA to 0/NA (marks an interval as a possible overrun, where the notes from a previous record have overrun onto the next line) |
Check original paper log |
flag_int_shortform | Interval which is not the first and has a from of 0/NA and a non-missing to . Often (but not always), this indicates that the record was entered in short hand, by omitting from and only inputing the to s. |
Check original paper log; OR, If reasonable, fix from to be preceeding to in GWELLS |
flag_int_bottom | Bottom interval with zero depth. Either because to is 0/NA or because to == from . |
Use fix_bottom argument in wells_subset() to add 1m to this bottom interval (this is the default). |
fix_int_bottom | Whether the flag_int_bottom problem has been fixed or not (i.e. whether or not 1m has been added to the to bottom layer as well as to the depth of the well. |
|
flag_lith_overruns | Well with at least one overrunning interval (flag_int_overrun with missing depths). |
Check original paper log |
flag_lith_nodepths | All lithologic intervals have depths of 0/NA (from and to ) |
Check original paper log |
flag_lith_intervals | At least one flag present on at least one interval in this record | |
flag_lith_missing | No lithologic record for this well | |
flag_cat_bedrock | Interval where Bedrock occurs with any other primary term | Fix in GWELLS |
flag_pos_bedrock | A non-bedrock category occurs below a bedrock category | Fix in GWELLS |
flag_cat_boulders | Interval where Boulders occur with any other primary term | Fix in GWELLS |
flag_cat_missing | No categories were extracted from the cleaned lithologic interval | Open an issue |
flag_yield_mismatch | Lithology where there are both depths and yields, but the number of yield measures do not match up with the number of depth measures (thus yield and depths are NA). This only applies to Hydrostratigraphy. |
Check original paper log |
flag_yield_digits | Lithology with extra digits which were not converted to a yield or depth. This only applies to Hydrostratigraphy. | Fix in GWELLS |
flag_depth_missing | Well missing depth | Check original paper log |
fix_depth_missing | Whether the flag_depth_missing problem has been fixed or not (i.e. whether or not Well depth has been set to the non-missing depth of the final lithology interval) |
|
flag_depth_mismatch | Well where the well depth is not equal to the non-missing depth of the final lithology interval | Check original paper log |
