Seafloor Wells and TFL – A Review of Nine Operating Years

Don Keprta


Atlantic Richfield has completed eight seafloor wells in the Eugene Island Block 175 Field, offshore Louisiana. Initial installation was in 1966. These wells are remotely operated and serviced from a central platform through flowlines of lengths up to 6,175 feet. Operation of the wellheads and a variety of through-flowline (TFL) procedures have been performed repeatedly since installation. Although equipment failures have occurred, control of the wells has always been maintained.

This paper describes the surface, seafloor and downhole equipment installed, TFL operations and significant problems encountered.
