Abstract
The invention relates to a method (100) for determining a hydrocarbon-water contact position in a hydrocarbon reservoir, said method comprising the steps of:—Providing (110) at least two reservoir fluid samples collected, from connected hydrocarbon reservoir(s), at different known sampling depth values, —Measuring (120) abundance of at least one isotope of noble gas from each of the at least two reservoir fluid samples, and—Calculating (130) the hydrocarbon-water contact position in the hydrocarbon reservoir from the measured abundances and the known sampling depth values of the at least two reservoir fluid samples.

A method for determining a hydrocarbon-water contact position in connected hydrocarbon reservoir(s), said method comprising the steps of:
- Providing at least two reservoir fluid samples collected, from connected hydrocarbon reservoir(s), at different known sampling depth values,
- Measuring abundance of at least one isotope of noble gas from each of the at least two reservoir fluid samples, and
- Calculating the hydrocarbon-water contact position in the hydrocarbon reservoir(s) from the measured abundance(s) and the known sampling depth values of the at least two reservoir fluid samples.
A computer device for determining a hydrocarbon-water contact position in a hydrocarbon reservoir, said computer device comprising:
- A communication interface configured to acquire:
- Measured abundance value of at least one isotope of noble gas from each of at least two reservoir fluid samples from the hydrocarbon reservoir, and
- Depth of collection values of the at least two reservoir fluid samples in the hydrocarbon reservoir;
- A processor configured to calculate hydrocarbon-water contact position in the hydrocarbon reservoir, from the measured abundance values and known depth values of the at least two reservoir fluid samples.
