Detailed Description

template<class FluidSystem, class Region>
class Opm::RateConverter::SurfaceToReservoirVoidage< FluidSystem, Region >

Convert component rates at surface conditions to phase (voidage) rates at reservoir conditions.

The conversion uses fluid properties evaluated at average hydrocarbon pressure in regions or field.

Template Parameters

FluidSystem	Fluid system class. Expected to be a BlackOilFluidSystem
Region	Type of a forward region mapping. Expected to provide indexed access through operator[]() as well as inner types value_type, size_type, and const_iterator. Typically std::vector<int> .

Member Typedef Documentation

RegionId

template<class FluidSystem , class Region >

using Opm::RateConverter::SurfaceToReservoirVoidage< FluidSystem, Region >::RegionId = typename RegionMapping<Region>::RegionId

Region identifier.

Integral type.

SurfaceToReservoirVoidage()

template<class FluidSystem , class Region >

Opm::RateConverter::SurfaceToReservoirVoidage< FluidSystem, Region >::SurfaceToReservoirVoidage ( const PhaseUsage &  phaseUsage, const Region &  region  )

inline

Constructor.

Parameters

[in]

region

Forward region mapping. Often corresponds to the "FIPNUM" mapping of an ECLIPSE input deck.

Member Function Documentation

calcCoeff()

template<class FluidSystem , class Region >

template<class Coeff >

void Opm::RateConverter::SurfaceToReservoirVoidage< FluidSystem, Region >::calcCoeff	(	const RegionId	r,
		const int	pvtRegionIdx,
		Coeff &	coeff
	)		const

Compute coefficients for surface-to-reservoir voidage conversion.

Template Parameters

Input	Type representing contiguous collection of component rates at surface conditions. Must support direct indexing through operator[]() .
Coeff	Type representing contiguous collection of surface-to-reservoir conversion coefficients. Must support direct indexing through operator[]() .

Parameters

[in]	r	Fluid-in-place region of the well
[in]	pvtRegionIdx	PVT region of the well
[out]	coeff	Surface-to-reservoir conversion coefficients that can be used to compute total reservoir volumes from surface volumes with the formula q_{rT} = \sum_p coeff[p] q_{sp}. However, individual phase reservoir volumes cannot be calculated from these coefficients (i.e. q_{rp} is not equal to coeff[p] q_{sp}) since they can depend on more than one surface volume rate when we have dissolved gas or vaporized oil.

calcCoeffSolvent()

template<class FluidSystem , class Region >

template<class SolventModule >

void Opm::RateConverter::SurfaceToReservoirVoidage< FluidSystem, Region >::calcCoeffSolvent ( const RegionId  r, const int  pvtRegionIdx, Scalar &  coeff  ) const

inline

Compute coefficients for surface-to-reservoir voidage conversion for solvent.

Parameters

[in]	r	Fluid-in-place region of the well
[in]	pvtRegionIdx	PVT region of the well
[out]	double	Surface-to-reservoir conversion coefficients for solvent.
