1. A method of recovering production fluids from a well having a christmas tree, the christmas tree having a first flowpath which has an outlet, and a second flowpath, the method comprising diverting fluids from a first portion of the first flowpath to the second flowpath, and diverting the fluids from the second flowpath back to a second portion of the first flowpath, and thereafter recovering fluids from the outlet of the first flowpath. 2. A method as claimed in claim 1, wherein the first flowpath is a production bore. 3. A method as claimed in claim 1, wherein the second flowpath is an annulus bore. 4. A method as claimed in claim 1, wherein the fluids are diverted from the first flowpath through a conduit disposed in the first flowpath, and wherein the fluids are returned via the annulus between the conduit and the first flowpath. 5. A method as claimed in claim 4, wherein the bore of the conduit provides the second flowpath. 6. A method as claimed in claim 4, wherein the conduit is sealed to the first flowpath across an outlet of the flowpath. 7. A method as claimed in claim 1, wherein the christmas tree is attached to a wellhead, and wherein the first portion of the first flowpath is a lower part of the first flowpath proximate to the wellhead. 8. A method as claimed in claim 1, wherein the fluids are returned to the first flowpath at an upper portion of the first flowpath. 9. A method as claimed in claim 1, wherein the fluids are diverted via a cap connected to the tree. 10. A method as claimed in claim 9, wherein the fluids are diverted via the cap from the second flowpath to the second portion of the first flowpath. 11. A method as claimed in claim 9, wherein the fluids are diverted via the cap from the second portion of the first flowpath to the second flowpath. 12. A method as claimed in claim 9, wherein a pump or treatment apparatus is provided in the cap. 13. A method as claimed in claim 1, wherein a pump or chemical treatment apparatus is connected between the first and second flowpaths. 14. A method as claimed in claim 1, wherein the fluids are diverted through a crossover conduit between the first flowpath and the second flowpath.
