Salinity related calculations

pypetrophysics.salinity.NaCl_to_chlorides(salinity_NaCl)

Converts salinity value from ppm NaCl equivalent to ppm Chlorides.

Parameters:salinity_NaCl (float) – Water Salinity (ppm NaCl equivalent) Returns:Returns water salinity in ppm Chlorides. Return type:float

pypetrophysics.salinity.chlorides_to_NaCl(salinity_chlorides)

Converts salinity value from ppm Chlorides to ppm NaCl equivalent.

Parameters:salinity_chlorides (float) – Water Salinity (ppm Chlorides) Returns:Returns water salinity in ppm NaCl equivalent. Return type:float

pypetrophysics.salinity.rw_at_form_temp(rw, rw_temperature, temperature_units, new_temperature)

Converts formation water resistivity from a known temperature to formation temperature.

Parameters:

• rw (float) – Water Resistivity (ohmmm)
• rw_temperature (float) – Temperature Rw was measured at.
• temperature_units (string) – Temperature units. Enter f for degrees farenheit or c for degrees celsius.
• new_temperature (float) – Temperature to convert resistivity to.

Returns:

Returns water resistivity value at the required formation temperature.

Return type:

float

Raises:

Exception – Raise an exception if incorrect units are entered.
