[SCAL] - Adjust Wettability Schema

**Core Wettability State**_ (preserved or restored) and cleaning method are very important considerations in wettability estimation; kindly consider adding these reference lists as part of the schema._

 Wettability estimation is derived from primary imbibition and secondary drainage capillary pressure experiments therefore we need to add test type (centrifuge, porous plate, coreflood); fluid system type (O-W, G-W); displacing & displaced fluid type.

 Please find below a raw data template for Amott/USBM wettability experiment:

Main parameters to report out are: Iw**, Io, I and W**

Main Data

• Initial condition (Pc, Sw)
• Array column headers: Cycle (IMB/DRN), Pc, Sw
• Array for Area under Pc curve: Aimb, Adrn

Acceptance Criteira / Notes

• Add DesaturationMethod reference list to electrical properties schema

"DesaturationMethod": {
    "type": "string",
    "pattern": "^[\\w-.]:reference-data--DesaturationMethod:[\\w\\-\\.\\:\\%]+:[0-9]*$"
}

• Add displaced fluid type to electrical properties schema

"DisplacedFluid": {
    "type": "string",
    "description": "Fluid produced or displaced from a sample during capillary pressure testing, e.g. Brine, Hexane, or LiveCrudeOil",
    "pattern": "^[\\w-.]:reference-data--DisplacedFluidType:[\\w\\-\\.\\:\\%]+:[0-9]*$"
}

• Add displacing fluid type to electrical properties schema:

"DisplacingFluid": {
    "type": "string",
    "description": "Fluid introduced to a sample during capillary pressure testing, e.g. Mercury",
    "pattern": "^[\\w-.]:reference-data--DisplacingFluidType:[\\w\\-\\.\\:\\%]+:[0-9]*$"
}

• Add fluid system type reference list attribute to electrical properties schema

"FluidSystem": {
    "type": "string",
    "pattern": "^[\\w\\-\\.]+:reference-data--FluidSystemType:[\\w\\-\\.\\:\\%]+:[0-9]*$"
}

• Rename WettingIndex to WettabilityIndex
• Remove Fluid System property from WettabilityIndex array
• Introduce WettabilityIndexType string instead and manifest the following reference values
  • Oil
  • Water
  • Wettability
  • Amott
  • Harvey

"WettabilityIndex": {
    "type": "array",
    "description": "Wettability index",
    "items": {
        "type": "object",
        "properties": {
            "Value": {
                "type": "number"
            },
            "UnitOfMeasure": {
                "type": "string",
                "pattern": "^[\\w\\-\\.]+:reference-data--UnitOfMeasure:[\\w\\-\\.\\:\\%]+:[0-9]*$"
            },
            "WettabilityIndexType": {
                "type": "string",
                "pattern": "^[\\w\\-\\.]+:reference-data--WettabilityIndexType:[\\w\\-\\.\\:\\%]+:[0-9]*$"
            }
        },

• Add InitialWaterSaturation and InitialCappillaryPressure objects to the schema: Value + UOM

"InitialWaterSaturation": {
    "type": "object",
    "description": "initial water saturation expressed as a fraction of the pore volume",
    "properties": {
        "Value": {
            "type": "number"
        },
        "UnitOfMeasure": {
            "type": "string",
            "pattern": "^[\\w\\-\\.]+:reference-data--UnitOfMeasure:[\\w\\-\\.\\:\\%]+:[0-9]*$"
        }
    },
    "additionalProperties": false
},
"InitialCappillaryPressure": {
    "type": "object",
    "properties": {
        "Value": {
            "type": "number"
        },
        "UnitOfMeasure": {
            "type": "string",
            "pattern": "^[\\w\\-\\.]+:reference-data--UnitOfMeasure:[\\w\\-\\.\\:\\%]+:[0-9]*$"
        }
    },
    "additionalProperties": false
},

• Add ForcedWaterImbibition and ForcedOilOmbibition objects (Value+UOM), based on sample data don't know whether it really should be an array

"CurveAreaImbibition": {
    "type": "object",
    "properties": {
        "Value": {
            "type": "number"
        },
        "UnitOfMeasure": {
            "type": "string",
            "pattern": "^[\\w\\-\\.]+:reference-data--UnitOfMeasure:[\\w\\-\\.\\:\\%]+:[0-9]*$"
        }
    },
    "additionalProperties": false
},
"CurveAreaImbibition": {
    "type": "object",
    "properties": {
        "Value": {
            "type": "number"
        },
        "UnitOfMeasure": {
            "type": "string",
            "pattern": "^[\\w\\-\\.]+:reference-data--UnitOfMeasure:[\\w\\-\\.\\:\\%]+:[0-9]*$"
        }
    },
    "additionalProperties": false
},
