a co-operating surface configured for co-operating with the co-operating fluid conductor, while the flow diverter is disposed within the wellbore and oriented for receiving at least reservoir fluids via the first inlet port, to define an intermediate fluid passage therebetween for effecting fluid communication between the first outlet ports and the second inlet ports.

2. The flow diverter as claimed in claim 1 ;

wherein for at least one of the first fluid passage branches, the first fluid passage branch includes one or more first fluid passage branch portions, wherein each one of the one or more first fluid passage branch portions, independently, has an axis that is disposed at an angle of less than 30 degrees relative to the axis of the first inlet port.

3. The flow diverter as claimed in claim 2 ;

5. The flow diverter as claimed in claim 4 ;

wherein, for at least one of the first fluid passage branches, the first fluid passage branch includes one or more first fluid passage branch portions, and with respect to each one of the one or more first fluid passage branch portions, independently, the first fluid passage branch portion is oriented such that, while the flow diverter is disposed within a wellbore section and oriented for receiving at least reservoir fluids via the first inlet port, the first fluid passage branch portion is disposed at an angle of less than 30 degrees relative to the axis of the wellbore section within which the flow diverter is disposed.

6. The flow diverter as claimed in claim 5 ;

wherein each one of the one or more first fluid passage branch portions, independently, has an axis that is disposed at an angle of less than 30 degrees relative to the axis of the wellbore section within which the flow diverter is disposed.

7. The flow diverter as claimed in claim 6 ;

8. The flow diverter as claimed in claim 1 ;

wherein for at least one of the second fluid passage branches, the second fluid passage branch includes one or more second fluid passage branch portions, wherein each one of the one or more second fluid passage branch portions, independently, has an axis that is disposed at an acute angle relative to the axis of the second outlet port.

9. The flow diverter as claimed in claim 8 ;

wherein each one of the one or more second fluid passage branch portions, independently, has an axis that is disposed at an angle of less than 30 degrees relative to the axis of the second outlet port.

10. The flow diverter as claimed in claim 9 ;

wherein the one or more second fluid passage branch portions define at least a second fluid passage branch fraction, and wherein the axial length of the second fluid passage branch fraction defines at least 25% of the total axial length of the second fluid passage branch.

11. The flow diverter as claimed in claim 1 ;

wherein, for at least one of the second fluid passage branches, the second fluid passage branch includes one or more second fluid passage branch portions, and with respect each one of the one or more second fluid passage branch portions, independently, the second fluid passage branch portion is oriented such that, while the flow diverter is disposed within a wellbore section and oriented for receiving at least reservoir fluids via the first inlet port, the second fluid passage branch portion is disposed at an acute angle relative to the axis of the wellbore section within which the flow diverter is disposed.

12. The flow diverter as claimed in claim 11 ;

wherein each one of the one or more second fluid passage branch portions, independently, has an axis that is disposed at an angle of less than 30 degrees relative to the axis of the wellbore section within which the flow diverter is disposed.

13. The flow diverter as claimed in claim 12 ;
