Claim 0:
1. A method comprising:
coupling, by a packer, a first tubing and a second tubing while sealing against a wall of a wellbore formed in a subterranean formation, such that fluid flow across the packer in a first direction is restricted to flowing through the first tubing and fluid flow across the packer in a second direction different from the first direction is restricted to flowing through the second tubing;
flowing a first hydrocarbon stream across the packer from a surface location through the first tubing to a downhole location within the wellbore, wherein the first hydrocarbon stream has a hydrogen sulfide content that is less than a hydrogen sulfide content of downhole fluids present in the subterranean formation; and
flowing a second hydrocarbon stream across the packer from the downhole location through the second tubing to the surface location, wherein the second hydrocarbon stream has a hydrogen sulfide content that is intermediate of the hydrogen sulfide content of the downhole fluids and the hydrogen sulfide content of the first hydrocarbon stream.
