WellLog consistency rules

WellLog entity : Meta only (record) consistency

Rules

see WellLog schema.

  • rule 1: Each CurveID listed in data.Curves.CurveID must be unique.

  • rule 2: Ensure data.ReferenceCurveID exists in data.Curves.CurveID list.

Example

wellog record:

{
"id": "...",
"data": {
  "ReferenceCurveID": "MD",
  "SamplingStart": 7627.0,
  "SamplingStopt": 7627.6,
  "Curves": [​
      {​
        "CurveID": "CSHG",​
        "Mnemonic": "CSHG",​
        "LogCurveFamilyID": "data-partition-id:reference-data--LogCurveFamily:Core%20Mercury%20Saturation:",​
        "NumberOfColumns": 4
      },​
      {​
        "CurveID": "MD",​
        "CurveUnit": "data-partition-id:reference-data--UnitOfMeasure:ft:",​
        "Mnemonic": "MD",​
        "LogCurveFamilyID": "data-partition-id:reference-data--LogCurveFamily:Measured%20Depth:",​
        "NumberOfColumns": 1​
      }​
  ],​
       
}

  • rule 1: Each Curves.CurveID is unique, here MD and CSHG.

  • rule 2: ReferenceCurveID is set to MD and MD exists Curves.CurveID list.

WellLog entity : Meta data (record) & Bulk data consistency

WellLog record can exist without bulk data​.

Rules

When bulk is added\edited following checks to be done :​

  • rule 3: Ensure Curves.CurveID listed in the record match the column names in the bulk​.

  • rule 4: For each curve, ensure that NumberOfColumns matches the column count in the bulk​ for this curve.

Example

WellLog bulk data:

DEPTH CSHG[0] CSHG[1] CSHG[2] CSHG[3]
7627.0 0.573 0.573 0.573 0.573
7627.1 0.531 0.531 0.531 0.531
7627.2 0.653 0.653 0.653 0.653
7627.3 0.788 0.788 0.788 0.788
7627.4 0.034 0.034 0.034 0.034
7627.5 0.035 0.035 0.035 0.035
7627.6 0.607 0.607 0.607 0.607

using previous section well log record.

  • rule 3: Curves.CurveID list, DEPTH and CSHG matches the column names in the bulk​. Here CSHG is an array with 4 columns: CSHG[0], CSHG[1], CSHG[2], CSHG[3].

  • rule 4: DEPTH.NumberOfColumns matches the column count in the bulk​ ==> 1. CSHG.NumberOfColumns matches the column count in the bulk​ ==> 4, CSHG[0], CSHG[1], CSHG[2], CSHG[3].

Additional rules when the reference is type "Measured Depth".

The following rules are only applied if the reference is type "Measured Depth".

Rules

  • rule 5: The values associated to the ReferenceCurveID in the record are monotonic​.

  • rule 6: The top and bottom bulk values associated to the ReferenceCurveID should match values data.SamplingStart and data.SamplingStop in the record.

Example

from previous record and bulk data:

record:

{
"id": "...",
"data": {
  "ReferenceCurveID": "MD",
  "SamplingStart": 7627.0,
  "SamplingStop": 7627.6,

bulk:

DEPTH ...
7627.0 ...
7627.1 ...
7627.2 ...
7627.3 ...
7627.4 ...
7627.5 ...
7627.6 ...
  • rule 5: The values associated to the ReferenceCurveID,DEPTH, are monotonic​: no duplicates, strictly increasing, no missing values.
  • rule 6: data.SamplingStart matches bulk DEPTH top value ==> 7627.0. data.SamplingStop matches bulk DEPTH bottom value ==> 7627.6.
