Abstract
A method for estimation of water properties and hydrocarbon properties in a subsurface formation include acquiring a plurality of well log measurements from the subsurface formation. The water properties and the formation properties are parameterized with respect to a selected set of well log measurements. The parameterized water properties, the parameterized formation properties and the well log measurements are graphically displayed to estimate the water properties.
Claims21
A method for estimation of water properties and hydrocarbon properties in a subsurface formation comprising:
- acquiring a plurality of well log measurements from the subsurface formation;
- parameterizing the water properties and the formation properties with respect to a selected set of well log measurements;
- and
- graphically displaying the parameterized water properties, the parameterized formation properties and the well log measurements to estimate the water properties.
A system for characterizing subsurface formation fluid content, comprising:
- a plurality of well logging sensors each measuring a different physical parameter of the subsurface formation at a plurality of depths of investigation from a wall of the a wellbore;
- a predetermined set of values of response of each of the well logging sensors to water having a plurality of values of salinity and formation lithologies having known response to selected well log measurements;
- and
- means for graphically displaying the parameterized water properties, the formation properties and the well log measurements to estimate the water properties.
