Mixer calculation
This function performs a mixer calculation to combine external streams and flash at an isothermal condition.
Request payload
params | type | description |
name | string | name of output stream |
chemistryModel | string | chemistry model file (dbs) name for mixer calculation |
externalStreams | array of objects | |
inletInputs | array of objects | |
temperature | specified temperature with unit | |
pressure | specified pressure with unit | |
inheritOptions | boolean | Optional, option to apply "optionalProperties" and "unitSetInfo" to calculation objects in "externalStreams". Default is false |
External streams
External streams can be calculated by three types of inputs at isothermal conditions: 1) ionic species composition, 2) inflow species composition, 3) mixer calculation to combine calculated external stream.
Common external stream inputs
params.externalStreams[{}] | type | description |
name | string | external stream name |
chemistryModel | string | optional, chemistry model file (dbs) name for external stream |
"chemistryModel" input is optional. The chemistry model file of the mixer calculation will be used if this input is missing.
External stream from ionic input
All inputs are specified as an array of objects in "waterAnalysisInputs", which are explained in water analysis calculation.
External stream from inflow input
params.externalStreams[{}] | type | description |
inflows | object | |
temperature | specified temperature with unit | |
pressure | specified pressure with unit | |
saturateWithH2O | string | optional, could be specified as "gas" or "oil", which will add H2O to the system to saturate the corresponding phase with water |
External stream from mixer calculation
params.externalStreams[{}] | type | description |
inletInputs | array of objects | name, type, and flow rate for combining stream, as explained in inlet specification |
temperature | specified temperature with unit | |
pressure | specified pressure with unit |
External streams are calculated in the order of the input array. Any mixer calculation specified in external streams can combine external streams that are already calculated.
Any mixer calculation in external streams can be treated as an inlet for followed mixer calculations. In other words, mixer calculations can be specified cascadingly in external streams.
Inlet specification
params.inletInputs[{}] | type | description |
streamName | string | name of the external stream to be combined in mixer |
streamType | string | stream type, this determines target phases to be combined in mixer |
totalAmount | inlet stream flow rate with unit explained below | |
automaticFlowRate | boolean | optional, when speciefied as true, total flow rate specified in the external stream will be used, then "totalAmount" is not needed |
"automaticFlowRate" can only be specified true when the corresponding external stream is calculated in flowing system.
Inlet stream types
params.inletInputs[{}].streamType | phases to be combined | phase property to be used in calculating flow rate |
brine | liquid-1 | liquid-1 |
oil | vapor, liquid-2 | liquid-2 |
gas | vapor, liquid-2 | vapor |
whole fluid | liquid-1, liquid-2, vapor | all phases |
params.inletInputs[{}].streamType | params.inletInputs[{}].totalAmount.unit numerators |
brine, whole fluid | bbl, L, ml, cm3, m3, E3m3, E6m3, ft3, Mft3, MMft3, gal, MMgal |
oil | std bbl, std m3, std L, bbl, m3, L |
gas | std MMft3, std Mft3, std ft3, std E3m3, std m3, std L, MMft3, Mft3, ft3, E3m3, m3, L |
params.inletInputs[{}].totalAmount.unit is flow rate unit with volumetric units as shown above divide by a time unit, i.e. bbl/day. Available time units are s, min, hr, day, yr.
Saturator option (optional)
This option can be specified to saturate one or more solid species by varying the inflow species.
params.saturatorOptions[{}] | type | description |
mineralToSaturate | string | solid species to be saturated, using "trueName" for species with solid phase. See chemistry information. |
inflowToVary | string | varying inflow species, using "baseName" for inflows. See chemistry information. |
Additional input
In addition to the inputs shown above, some optional properties may also be specified. They can be viewed here.
Response (status = PROCESSED)
The "result" contains all stream outputs for each external stream and the final mixer outlet stream by their names specified in the input.
Survey Calculation
Survey calculation is supported for the variables below. Please refer to Survey calculation for explained input schema.
supported params.surveyInputs[{}].field |
"/params/temperature/value" |
"/params/pressure/value" |
"/params/inletInputs/i/totalAmount/value" where i is the index (0 based) of the params.inletInputs array of objects |
