Opportunity from Complexity... in our own Backyard: Exploration in the Northern Gulf of Mexico, Offshore U.S.

Cindy A. Yeilding and David I. Rainey, BP

Exploration in the U.S. Gulf of Mexico has been ongoing since the first successful offshore well in the 1940s. To date, over 64 billion barrels oil equivalent have been discovered in the U.S. offshore. The first 40 years of Exploration were dominated by activity in the Upper Tertiary of the Shelf, and industry moved into deepwater water (>1000’) en masse with the 1985 area-wide OCS lease sales.
The first “Round” of deepwater leasing (1985-1994) yielded success in a number of seismic attribute-related upper Miocene and younger discoveries. These discoveries, including Mars, Ursa and Ram Powell, were enabled through the application of 3D seismic time processing at scale and 4th generation drilling capability in 3000-5000’ of water. The second “Round” of leasing and drilling focused on older stratigraphy, and on testing robust structural culminations, many of which were partially or completely subsalt. These discoveries, including Thunder Horse, Atlantis and Mad Dog, resulted from the integration of geological first principles with 3D seismic depth processing. They were enabled by 5th generation drilling rigs with capability to drill in 5,000-10,000’ of water, as well as the ability to drill to a total depth of over 30,000’.

The Gulf of Mexico portfolio of opportunities continues to evolve. Most recent drilling activity has yielded a series of oil discoveries in the Paleogene strata of the deepwater. Significant discoveries in this play include Jack, Kaskida and Stones. The industry is currently positioned to extend this Paleogene play northwards as it targets deep gas trends under the shallow water Gulf of Mexico shelf. In addition, the most recent step change in seismic imaging, the application of multi-azimuth acquisition techniques at scale, has potential to extend existing plays under ever more complex and difficult to image salt. As 6th generation drilling rigs move from the drawing board to the ship yard, the future for exploration in the Gulf of Mexico remains as bright as ever.

Speaker Cindy A. Yeilding

Cindy Yeilding earned her MSc in 1984 from the University of North Carolina, Chapel Hill after receiving a BS in Geology from SMU. She has worked as an exploration, production, appraisal and well site operations geoscientist and is currently BP's Exploration Renewal Manager, US. Her most recent roles include Chief Geoscientist for the Gulf of Mexico, Global Geoscience Technology and R&D Manager for BP, Seismic Imaging R&D Manager, Team Leader, Gulf of Mexico and Team Leader, Venezuela Exploration.

She has developed and led short courses and field seminars, and in 2002-2003 she served as an AAPG Distinguished Lecturer. She has also chaired numerous AAPG sessions, presented numerous technical talks, and participated in Hedberg conferences. Her primary research has been in salt sediment interactions and exploration of deepwater clastic deposystems, with development, access, and testing of new plays.
