“…The Ardath Shale lies unconformably on top of the marginal-marine Torrey Sandstone and nonmarine Delmar Formation. The Ardath sandstone is an informal term for a sandstone lithofacies located at the base of the Ardath outside of the field area (modified with permission by Pacific Section SEPM from Campion et al, 1996;and May and Warme, 2000).…”

“…In this area, the basin margin morphology transitioned rapidly from a narrow, steep coastal plain to a slope cut by submarine canyons (May, 1982;May and Warme, 2000). Facies deposited along this margin transitioned rapidly westward from alluvial and fluvial to slope and bathyal submarine canyon sediments (Lohmar et al, 1979;May and Warme, 2000). These eastwardthinning deposits lapped onto the crystalline basement of the Peninsular Ranges, comprising Upper Jurassic volcanic rocks and mid-Cretaceous plutonic rocks of an extinct magmatic arc (Kennedy and Moore, 1971;Nilsen, 1977).…”

Beach north of La Jolla, California, record a deep-water channelized slope system of an Eocene forearc basin. The outcrop exposure, which is approximately 100 m (330 ft) high by 1.7 km (~1 mi) long, offers insight into reservoir distribution and connectivity within coarse-grained, confined, deep-water channel systems. To use this outcrop as a quantitative subsurface analog, a detailed two-dimensional lithologic model was constructed from measured sections and interpreted photopanels. Elastic rock properties, including compressional-wave velocity, shear-wave velocity, and density typical of shallow offshore west African reservoirs were used to construct an impedance model. This model was convolved with 15-, 25-, and 50-Hz quadrature-phase Ricker wavelets to generate near-and far-angle stack one-dimensional and two-dimensional synthetic seismic reflection models. Because deep-water lithofacies have distinct amplitude-variation-withoffset behaviors and the interpretation of surfaces is intimately coupled with predicting lithofacies, simple bed interface models of conglomerate, sandstone, interbedded sandstone and mudstone, and muddy sandy debrite were used to build a template for successful interpretation.Interpretation of these forward seismic models demonstrates (1) the limits of and uncertainty associated with the interpretation of seismic data at different frequencies commonly encountered in the exploration, development, and production of deep-water reservoirs; and (2) how the combination of near-and far-angle seismic data can be used to interpret channel-fill lithofacies and Lisa Stright is an assistant professor of hydrocarbon geosciences in the Department of Geology and Geophysics at the University of Utah. She leverages her combined engineering and geology background to couple quantitative observations from outcrop analogs and subsurface data sets to build more predictive geocellular and flowsimulation models.

“…Interpretation of the high-resolution seismic data is being supported by increasing well log and core data. Accompanying the subsurface data, outcrop analogue studies and studies of modern and Pleistocene channel systems have resulted in an extensive and mounting literature on the nature of turbidite channel reservoirs (Abreu et al, 2003;Adedayo et al, 2005;Babonneau et al, 2002;Beaubouef, 2004;Beaubouef et al, 1999;Browne and Slatt, 2002;Busby and Camacho, 1998;Campion et al, 2000;Clark and Gardiner, 2000;Clark and Pickering, 1996a, b;Cook et al, 1994;Cronin, 1995;Cronin and Kidd, 1998;Cronin et al, 2000Cronin et al, , 2002Damuth et al, 1983;DeVries and Lindholm, 1994;Elliott, 2000;Emmel and Curray, 1985;Eschard et al, 2003;Gardner and Borer, 2000;Gardner et al, 2003;Haughton, 2000;Hickson and Lowe, 2002;Johnson et al, 2001;Kenyon et al, 1995;Kirschner and Bouma, 2000;Kneller, 2003;Link and Stone, 1986;Lomas et al, 2000;May and Warme, 2000;Busby-Spera, 1988, 1990;Mulder et al, 2003;Peakall et al, 2000;Pirmez et al, 2000;Pirmez and Imran, 2003;Prather et al, 2000;Samuel et al, 2003;…”

Active margin continental slope outcrops from the Eocene Juncal Formation, the Eocene La Jolla Group and the Miocene Capistrano Formation display sedimentary structures and depositional geometries that suggest deposition from Froude supercritical flow, based on comparison to strata produced by flume experiments. These deposits range from boulder‐size soft clasts and cobble‐size hard clasts to silt and mud, and display long‐wavelength and low‐amplitude convex‐up and concave‐up geometries that range from centimetre to hundreds of metres scale, low‐angle foresets and backsets, and common internal and bounding erosion surfaces from centimetres to tens of metres in depth. In places, planar laminations, structureless beds and normally graded beds are laterally or vertically associated with such structures. In other places, consistent backsets or deep and steep‐sided scours occur. This study aimed to discuss the origin of the observed bedforms, contributed to recognition of supercritical flow deposits on continental slopes and expanded the outcrop examples of supercritical flow deposits to silt and mud. This work implies that the erosive and powerful Froude supercritical flow turbidity currents may have a substantial impact on erosional and depositional dynamics on deepwater slopes, especially on active margins due to the steep gradients and high sediment supply.
