The assets include Shell's 100% interest in Green Canyon blocks 114, 158, 202 and 248, as well as the Brutus tension-leg platform.
The deal with EnVen also includes the Glider subsea production system and the oil and gas lateral pipelines used to offload the platform's production.
In May, a segment of the subsea flowline at Glider, which is tied back through four wells to the Brutus tension-leg platform, was identified as the source of a 2100-barrel release of oil-water mixture.
