Dear all,

Please suggest how to identify the nature of reservoir fluid whether it is sweet or sour condition based on the reservoir composition at reservoir fluid condition.

Thanks.

Regards,

kasri

While the definition may be slightly different to different groups, if it has more than a few ppm H2S in it, it is sour. If it has more than 2% CO2, it is sour. Otherwise it is sweet.

dear rock dock,

thanks for your response.

Please inform is it any limit for H2S to say the fluid as sour.

Is it both H2s and CO2 presence called sour or only H2S is sour.

Please suggest.

thanks

H2S is what people are normally worried about. I wouldn't worry about CO2 unless it is specifically mentioned as a specification.
