Niger Delta. West of Shetland. Campos-Santos basins. Gulf of Mexico. All testing grounds for our understanding of deep-water sedimentary systems. High risk. High pressure. High temperature. High rates. Decades of high production. Low maintenance. Low environmental and carbon footprint. The discoveries in these offshore regions around the 1980s prompted explorers to think: “Where else in the world can large oil fields with high-quality turbidite reservoirs be found?” In this way, deepwater became a target to pursue on a global scale (Fremin et al., 2022; Sears et al., 2022).
Recent, large discoveries in frontier settings offshore Africa (and the conjugates) have bolstered a positive trajectory for the deepwater creaming curve (Fig. 1 – Minken et al., 2022). The industry is in a deepwater renaissance, with the curve not showing signs of flattening. Not only have these discoveries increased the deepwater resource base, but they have also called into question the turbidite paradigm that persisted in exploration workflows since the final third of the 20th century.
Before the large African discoveries in the early 21st century, the search for conventional turbidite reservoirs promoted a singular focus on deep-water sediment transport and depositional models dominated by downslope processes. Turbidites, debrites and transitional flow deposits were interpreted to be responsible for diverse submarine fan depositional systems comprised of elegantly interconnected canyon, channel, levee, splay and overbank environments. Today, along-slope as well as downslope (i.e., turbidity current) processes are interpreted to sculpt the modern seafloor (Fig. 2 – Rotzien et al., 2022; Hernández-Molina et al., 2022). Ancient stratigraphic successions in revered outcrops such as the Annot Sandstone (Grès d’Annot) in France also reveal evidence of along-slope sediment transport and deposition. In response, wildcatters and academic researchers alike have refreshed interpretations and depositional models to communicate new observations on mixed deep-water sedimentary systems to scientific and industry communities as oil price remains high in the near term.
This presentation focuses on deep-water sedimentary processes and deposits, their predictive attributes and their 3D heterogeneity. While much of the global knowledge on deepwater has been generated through decades of oil and gas drilling, a firm understanding of deep-water sedimentary processes is essential for many offshore endeavors that take place in the water column, at the seabed, and into the subsurface, as well as onshore projects that involve deep-water sedimentary intervals. Professionals and students in the fields of oil and gas exploration and production, carbon capture, use and sequestration, geothermal, wind, solar, aquaculture, mining, military, insurance and government are invited to attend this discussion on the past, present and future of deepwater.

Jon Rotzien is President of Basin Dynamics and Adjunct Professor at University of Houston. He specializes in reservoir presence and quality forecasting in conventional and unconventional drilling programs. Prior to his present posts, he served BP and other supermajor and independent operators in a variety of basins and petroleum reservoir technical training programs. As a business owner and scientist, Rotzien has participated in oil and gas exploratory to development drilling, mapping expeditions, technical competency training and consulting and has served as lead geologist in about one-third of those ventures. He is currently serving as Chair of the Houston Explorers Club. Rotzien received a Ph.D. in Geological Sciences from Stanford University and a B.A. degree in Geology from Colorado College.
