Abstract
A method and system for determining fluid saturation within a fracture. The method comprises the steps of establishing a functional relationship between fluid saturation and capacitance for a multiple component fluid; introducing the fluid between the fracture faces of the fractured media; measuring electrical capacitance between the fracture faces; and determining fluid saturation from the capacitance measurement and the functional relationship. The method and system find utility with both simulated and natural fractures.
Claims21
A method for determining fluid saturation within a fracture of a fractured material, having at least a first and second fracture face, comprising the steps of:
- (a) establishing a functional relationship between fluid saturation and capacitance for a multiple component fluid;
- (b) introducing the fluid between the fracture faces;
- (c) measuring electrical capacitance between the fracture faces;
- and
- (d) determining fluid saturation from the capacitance measurement of step (b) and the relationship established in step (a).
A system for determining fluid saturation within a fracture of a fractured material having at least a first and second fracture face, comprising:
- (a) a flow cell for mounting the fractured material therein;
- (b) means for measuring the capacitance between the fracture faces;
- and
- (c) means for providing a regulated flow of test fluid.
