bhp() [1/2]

template<class EvalWell >

EvalWell Opm::VFPProdProperties::bhp	(	const int	table_id,
		const EvalWell &	aqua,
		const EvalWell &	liquid,
		const EvalWell &	vapour,
		const double &	thp,
		const double &	alq,
		const double &	explicit_wfr,
		const double &	explicit_gfr,
		const bool	use_expvfp
	)		const

Linear interpolation of bhp as a function of the input parameters given as Evalutions Each entry corresponds typically to one well.

Parameters

table_id	Table number to use. A negative entry (e.g., -1) will indicate that no table is used, and the corresponding BHP will be calculated as a constant -1e100.
aqua	Water phase
liquid	Oil phase
vapour	Gas phase
thp	Tubing head pressure
alq	Artificial lift or other parameter

Returns

The bottom hole pressure, interpolated/extrapolated linearly using the above parameters from the values in the input table, for each entry in the input ADB objects.

bhp() [2/2]

double Opm::VFPProdProperties::bhp	(	int	table_id,
		const double &	aqua,
		const double &	liquid,
		const double &	vapour,
		const double &	thp,
		const double &	alq,
		const double &	explicit_wfr,
		const double &	explicit_gfr,
		const bool	use_expvfp
	)		const

Linear interpolation of bhp as a function of the input parameters.

Parameters

table_id	Table number to use
aqua	Water phase
liquid	Oil phase
vapour	Gas phase
thp	Tubing head pressure
alq	Artificial lift or other parameter

Returns

The bottom hole pressure, interpolated/extrapolated linearly using the above parameters from the values in the input table.

thp()

double Opm::VFPProdProperties::thp	(	int	table_id,
		const double &	aqua,
		const double &	liquid,
		const double &	vapour,
		const double &	bhp,
		const double &	alq
	)		const

Linear interpolation of thp as a function of the input parameters.

Parameters

table_id	Table number to use
aqua	Water phase
liquid	Oil phase
vapour	Gas phase
bhp	Bottom hole pressure
alq	Artificial lift or other parameter

Returns

The tubing hole pressure, interpolated/extrapolated linearly using the above parameters from the values in the input table.

Find the function bhp_array(thp) by creating a 1D view of the data by interpolating for every value of thp. This might be somewhat expensive, but let us assome that nthp is small.
