(SPE 224044) The Evolution of Riserless Wireline Subsea Intervention in Deepwater Gulf of Mexico, Doing More with Less by S. E. Townsend, J. Duenas, and L. W. Ramnath, BP America Inc
Riserless Light Well Interventions (RLWI) were conducted within the niche deepwater subsea environment of the Gulf of Mexico. The drivers for RLWI were mainly cost reduction and acceleration of intervention scopes, to ultimately improve well-productivity and prevent production deferrals.
The RLWI operations discussed focus on Miocene aged horizons in three assets (operated in water depths ranging from 5,400-ft to 6,800-ft respectively):
- one high-pressure high-temperature asset completed with 15,000-psi equipment and vertical subsea trees (VXT)
- another asset completed with 10,000-psi equipment and horizontal subsea trees (HXT)
- a third asset completed with both 10,000 psi and 15,000 psi equipment with both vertical and horizontal trees
For all three assets, RLWI was facilitated using a well control package (WCP) deployed onto the VXT or HXT, along with an auxiliary umbilical assembly (AUA), which provided the hydraulic control capability for the barrier valves/rams on the WCP. The umbilical hydraulic supply was located on the RLWI vessel.

He started bp as a Sr. Completions Engineer working for Atlantis Development before moving to the Deputy Completions & Interventions Manager for GoM and then He moved to the Sr. HSE&C Manager for bp’s global Wells team. Lawrence currently serves as the BP GoM Interventions Manager overseeing both engineering for both dry and subsea wells.
Eliot Townsend has 18-years of experience and has a Bachelor’s of Science in Petroleum Engineering from the University of Oklahoma with a minor in mathematics. Eliot joined bp in 2007 in Alaska where he worked as a well integrity engineer, production engineer, well site leader, and well interventions superintendent in the Prudhoe Bay Field. While working in Alaska, Eliot obtained his professional engineering license as a Petroleum Engineer. After 13 years in Alaska, Eliot moved to Aberdeen, Scotland and worked for bp as a Senior Well Interventions Engineer for light well intervention operations in the North Sea. After the overseas assignment, Eliot returned to the U.S. and worked in bp’s central engineering team as a wireline and well interventions specialist in Houston before moving to the Gulf of Mexico wells team where He is currently working as an Interventions engineer for Riserless Light Well Interventions.
