# co2brinepvt(1)

compute and print pvt properties for co2 with brine

## NAME

co2brinepvt - compute and print pvt properties for co2 with brine

## SYNOPSIS

**co2brinepvt** \[*OPTIONS*\] *PROPERTY* *PHASE* *PRESSURE* *TEMPERATURE* \[*SALINITY*\] \[*RS*\] \[*RV*\] \[*SALTMODEL*\] \[*THERMAL\_MIXING\_MODEL\_GAS*\] \[*THERMAL\_MIXING\_MODEL\_LIQUID*\] \[*THERMAL\_MIXING\_MODEL\_SALT*\]

## DESCRIPTION

co2brinepvt computes PVT PROPERTY of a brine/co2 system. The computation is performed for a given PHASE (oil or brine), PRESSURE (in bar), TEMPERATURE (in Celsius),  SALINITY (salt molality in mol/kg) and RS (amount of dissolved CO2 in Brine in SM3/SM3), RV (amount of vaporized water in Gas in SM3/SM3), salt model (SALTMODEL), model of thermal mixing of gas, liquid, amd salt (THERMAL\_MIXING\_MODEL\_GAS ans THERMAL\_MIXING\_MODEL\_LIQUID,  respectively).

See CO2STORE in the OPM manual for more details.

PROPERTY, the property computed, may be one of

```
- density (the density)
- invB (the inverse phase formation volume factor
- viscosity
- rSat (saturated dissolution factor)
- internalEnergy (internal Energy)
- enthalpy
- diffusionCoefficient (the diffusion coefficient)
```

SALTMODEL, the model to use for salt, may be one of

```
- 0 = no salt activity
- 1 = Rumpf et al (1996) [default]
- 2 = Duan-Sun in Spycher & Pruess (2009)
- 3 = Duan-Sun in Sycher & Pruess (2005)
```

THERMAL\_MIXING\_MODEL\_GAS, the model of thermal mixing for gas, may be one of

```
- 0 = pure component [default]
- 1 = ideal mixing
```

THERMAL\_MIXING\_MODEL\_LIQUID, the model of thermal mixing for liquid, may be one of

```
- 0 = pure component
- 1 = ideal mixing
- 2 = heat of dissolution according to duan sun [default]
```

THERMAL\_MIXING\_MODEL\_SALT, the model of thermal mixing for salt, may be one of

```
- 0 = pure water
- 1 = model in MICHAELIDES [default]
```
