Abstract
In an example implementation, a production logging tool includes a housing that includes a first testing section defining a first central opening having a first diameter and a second testing section defining a second central opening having a second diameter different from the first diameter, a first flow sensor positioned within the first central opening, a second flow sensor positioned within the second central opening, and a sealing device configured to seal an annulus of a wellbore. The second central opening is fluidly coupled to the first central opening.
Claims17
A production logging tool comprising:
- a housing configured to be disposed within a wellbore, the housing having an uphole end and a downhole end, the uphole end closer to the surface compared to the downhole end, the housing comprising:
- a first testing section, wherein the first testing section defines a first central opening having a first diameter;
- and
- a second testing section between the first testing section and the uphole end of the housing, wherein the second testing section defines a second central opening having a second diameter smaller than the first diameter, wherein the second central opening is fluidly coupled to the first central opening;
- a third testing section between the second testing section and the uphole end of the housing, wherein the third testing section defines a third central opening with a third diameter smaller than the first diameter and the second diameter, wherein the third central opening is fluidly coupled to the second central opening;
- a first flow sensor positioned within the first central opening;
- a second flow sensor positioned within the second central opening;
- a third flow sensor positioned within the third central opening;
- and
- a sealing device configured to seal an annulus of the wellbore, the sealing device disposed closer to the downhole end than the uphole end.

A production logging method comprising:
- positioning a production logging tool in a wellbore;
- sealing an annulus of the wellbore proximate the production logging tool using a sealing device;
- measuring a first flow rate of formation fluid flowing in an uphole direction toward a surface of the wellbore through a first testing section of the production logging tool using a first sensor positioned in a first central opening defined by the first testing section;
- measuring a second flow rate of formation fluid flowing through a second testing section of the production logging tool positioned downstream of the first testing section using a second sensor positioned in a second central opening defined by the second testing section, wherein the first central opening is fluidly coupled to the second central opening and a diameter of the second central opening is smaller than a diameter of the first central opening;
- and
- measuring a third flow rate of formation fluid flowing through a third testing section of the production logging tool positioned downstream of the second testing section using a third sensor positioned in a third central opening defined by the third testing section, wherein the third central opening is fluidly coupled to the second central opening and a diameter of the third central opening is smaller than the diameter of the second central opening.

A downhole tool comprising:
- a downhole conveyance;
- a housing configured to couple with the downhole conveyance, the housing configured to be disposed within a wellbore, the housing having an uphole end and a downhole end, the uphole end closer to the surface compared to the downhole end, the housing comprising:
- a first testing section, wherein the first testing section defines a first central opening having a first diameter;
- and
- a second testing section between the first testing section and the uphole end of the housing, wherein the second testing section defines a second central opening having a second diameter smaller than the first diameter, wherein the second central opening is fluidly coupled to the first central opening;
- a third testing section between the second testing section and the uphole end of the housing, wherein the third testing section defines a third central opening with a third diameter smaller than the first diameter and the second diameter, wherein the third central opening is fluidly coupled to the second central opening;
- a first flow sensor positioned within the first central opening;
- a second flow sensor positioned within the second central opening;
- a third flow sensor positioned within the third central opening;
- and
- a sealing device configured to seal an annulus of the wellbore, the sealing device disposed closer to the downhole end than the uphole end.
