Detailed Description

Interpolant for Basic Gas PVT Relations.

Constructor & Destructor Documentation

Gas() [1/3]

Opm::ECLPVT::Gas::Gas	(	const ECLPropTableRawData &	raw,
		const int	usys,
		std::vector< double >	rhoS
	)

Constructor.

Parameters

[in]	raw	Raw tabulated data. Must correspond to the PVTG vector of an ECL INIT file..
[in]	usys	Unit system convention of the result set from which raw was extracted. Must correspond to item 3 of the INTEHEAD keyword in the INIT file.
[in]	rhoS	Mass density of gas at surface conditions. Typically computed by ECLPVT::surfaceMassDensity() .

~Gas()

Opm::ECLPVT::Gas::~Gas

(

)

Destructor.

Gas() [2/3]

Opm::ECLPVT::Gas::Gas

(

const Gas &

rhs

)

Copy constructor.

Parameters

[in]

rhs

Existing interpolant for Gas PVT relations.

Gas() [3/3]

Opm::ECLPVT::Gas::Gas

(

Gas &&

rhs

)

Move constructor.

Subsumes the implementation of an existing Gas PVT relation interpolant.

Parameters

[in]

rhs

Existing Gas PVT relation interpolant. Does not have a valid implementation when the constructor completes.

Member Function Documentation

formationVolumeFactor()

std::vector< double > Opm::ECLPVT::Gas::formationVolumeFactor	(	const int	region,
		const VaporizedOil &	rv,
		const GasPressure &	pg
	)		const

Compute the gas phase formation volume factor in a single region.

Parameters

[in]	region	Region ID. Non-negative integer typically derived from the PVTNUM mapping vector.
[in]	rv	Vaporised oil-gas ratio. Unused in the case of a dry gas model. Size must match number of elements in pg.data in the case of wet gas model. Strict SI units of measurement.
[in]	pg	Gas phase pressure. Strict SI units of measurement.

Returns

Gas phase formation volume factor. Size equal to number of elements in

po.data 

.

getPvtCurve()

std::vector< PVTGraph > Opm::ECLPVT::Gas::getPvtCurve	(	const RawCurve	curve,
		const int	region
	)		const

Retrieve 2D graph representation of Gas PVT property function in partcular PVT region.

Parameters

[in]	curve	PVT property curve descriptor
[in]	region	Region ID. Non-negative integer typically derived from the PVTNUM mapping vector.

Returns

Collection of 2D graphs for PVT property curve identified by requests represented by func and region. One curve (vector element) for each pressure node. Single curve (i.e., a single vector element) in the case of dry gas (no vaporised oil).

Example: Retrieve gas formation volume factor curve in PVT region 0 (zero based, i.e., cells for which PVTNUM==1).

const auto graph =
    pvtGas.getPvtCurve(ECLPVT::RawCurve::FVF, 0);

operator=() [1/2]

Gas & Opm::ECLPVT::Gas::operator=

(

const Gas &

Returns

*this 

.

operator=() [2/2]

Gas & Opm::ECLPVT::Gas::operator=

(

Gas &&

rhs

)

Move assignment operator.

Subsumes the implementation of an existing object.

Parameters

[in]

rhs

Existing Gas PVT relation interpolant. Does not have a valid implementation when the constructor completes.

Returns

.

surfaceMassDensity()

double Opm::ECLPVT::Gas::surfaceMassDensity

(

const int

region

)

const

Retrieve constant mass density of gas at surface conditions.

Parameters

[in]

region

Region ID. Non-negative integer typically derived from the PVTNUM mapping vector.

Returns

Mass density of gas at surface in particular model region.

viscosity()

std::vector< double > Opm::ECLPVT::Gas::viscosity	(	const int	region,
		const VaporizedOil &	rv,
		const GasPressure &	pg
	)		const

Compute the gas phase fluid viscosity in a single region.

Parameters

[in]	region	Region ID. Non-negative integer typically derived from the PVTNUM mapping vector.
[in]	rv	Vaporised oil-gas ratio. Unused in the case of a dry gas model. Size must match number of elements in pg.data in the case of wet gas model. Strict SI units of measurement.
[in]	pg	Gas phase pressure. Strict SI units of measurement.

Returns

Gas phase fluid viscosity. Size equal to number of elements in

pg.data
