Abstract
A method of using a tracer in a wellbore that includes disposing the tracer into the wellbore so that the tracer comes into contact with a target formation. Upon contacting the target formation for an amount of time, returning a remnant fluid that includes at least a portion of the tracer to a surface for testing. The tracer has a first composition, and in its original state is a solid non-magnetic powder.
Claims18
A method of using an inert, non-magnetic tracer in a wellbore, the method comprising:
- disposing the tracer into the wellbore so that the tracer comes into contact with a target formation in communication with the wellbore;
- upon contacting the target formation for an amount of time, returning a remnant fluid that includes at least a portion of the tracer to a surface;
- taking a sample of the remnant fluid;
- providing the sample to a surface facility;
- testing the sample at the surface facility via non-destructive energy dispersive x-ray fluorescence (EDXRF) in order to analyze the remnant fluid to provide a set of data associated with performance of the wellbore,
- wherein the inert, non-magnetic tracer has a first tracer composition, and
- wherein the inert, non-magnetic tracer is in a solid powder form having a bulk average particle diameter of at least 0.1 μm to less than 1 μm.

A method of using a tracer in a wellbore, the method comprising:
- disposing the tracer into the wellbore so that at some point thereafter the tracer comes into contact with a first stage of the wellbore;
- upon contacting the target formation for an amount of time, returning a remnant fluid that includes at least a portion of the tracer to a surface;
- taking a sample of the remnant fluid;
- providing the sample to a lab facility;
- filtering the sample to provide a filtered sample;
- testing the filtered sample at the lab facility via non-destructive energy dispersive x-ray fluorescence (EDXRF) in order to analyze the remnant fluid via energy excitation at sub-atomic level in order to provide a set of fluid data associated with an elemental composition of the remnant fluid;
- from the same wellbore, disposing a second tracer into the wellbore so that at some point thereafter the second tracer comes into contact with a second stage of the wellbore,
- wherein the tracer has a first tracer composition,
- wherein the tracer is in a non-magnetic solid powder form,
- wherein no step of the method uses or is associated with at least one of:
- a magnet, a magnetic feature, and combinations thereof,
- wherein the second tracer is also in a non-magnetic powder form,
- wherein each of the tracer and the second tracer have a respective bulk average particle diameter of at least 0.1 μm to less than 10 μm,
- wherein the set of data is used to provide a visual indicator related to performance of the wellbore, and
- wherein the visual indicator refers to at least one of:
- reservoir quality, completion quality, and combinations thereof.
