The carbonate and siliciclastic outcrops of the Guadalupe Mountains in the Permian Basin of West Texas and New Mexico have provided a rich set of basic and advanced conceptual models for geologists across the entire spectrum of experience for carbonate-ramp and steep-rimmed–platform settings as well as the adjacent deep-water siliciclastics not dealt with here.

Exceptional outcrop conditions in the Dolomites of northern Italy allow appreciation of facies variability, depositional geometries, and platform-to-basin relationships at seismic scale that developed during a complex sedimentary evolution. This itinerary focuses on two Triassic microbial carbonate platforms, the Latemar and Sella, providing examples of key concepts that are fundamental for the interpretation of subsurface geologic bodies.

The Upper Jurassic to Eocene carbonate rocks of the Gargano Promontory belong to the Apulia Carbonate Platform (ACP) and provide a spectacular and complete succession of slope and base-of-slope resedimented gravity flow carbonates with preserved reservoir properties and, with its coeval carbonate platform, displaying various tectonostratigraphic architectures.

Wave-dominated deltaic strata form prolific hydrocarbon plays in many mature basins across the world. Examples include the Jurassic Brent Group play in the North Sea, offshore United Kingdom and Norway (e.g., Husmo et al., 2003); Eocene Jackson Group and Oligocene Frio Formation plays, Texas, onshore United States (e.g., Fisher et al., 1970; Galloway and Morton, 1989); and Tertiary plays in the Niger Delta province, offshore Nigeria (e.g., Evamy et al., 1978), the Baram Delta province, offshore Brunei (e.g., Rijks, 1981), and the Columbus Basin, offshore Trinidad and Tobago (e.g., Sydow et al., 2003). Wave-dominated deltas also form key exploration targets in frontier basins (e.g., Triassic Snadd Formation, Barents Sea, offshore Norway; Klausen et al., 2014, 2016).

The Vercors Massif of southern France constitutes a world-class and unique opportunity to visualize depositional geometries and diagenetic transformations of a Barremian–early Aptian (early Cretaceous) carbonate system, the Urgonian platform, at a seismic scale and thus to constrain the three-dimensional continuity and connectivity of reservoir-prone facies deposited during periods of high and low sea level.

The Roda Sandstone Member (Lower Eocene, Tremp-Graus Basin, Spanish Pyrenees) is interpreted as a well-exposed multiscale Gilbert-type delta. It is formed by multiple prograding lobate-shaped sandstone bodies up to 5 km (3 mi) long and 2–3 km (1–2 mi) wide, each constructed by a number of smaller scale (hunderds of meters) lobes that stack in a compensational mode responding to relative base level changes.

The Jurassic carbonate platforms of the central High Atlas in Morocco are well known for several high-quality outcrops. In the central High Atlas, there are two complementary locations that offer critical lessons for our understanding of Jurassic carbonate system evolution in extensional basins: a Lower Jurassic high-relief, carbonate platform with steep slopes that developed on the footwall of a rotating fault block in an active half-graben (Djebel Bou Dahar [DBD]) and an upper Lower to Middle Jurassic low-angle prograding carbonate ramp rich in ooids (Amellago ramp [AR]).

Tide-dominated or tide-influenced coastal marine deposits form some of the most complicated and largest hydrocarbon fields in the world (Wood, 2004 and references cited therein). Good outcrop analogs can provide significant insight to geologists for recognizing tidal influence in core and interpreting petrophysical log data, thus reducing uncertainty and risk when developing depositional models and planning for field development.

Two-dimensional seismic refraction tomography was used to map the bedrock topography beneath Hallsands beach in southwest Devon, United Kingdom. Seismic refraction data were acquired from 11 spreads, 4 parallel to the beach and 7 normal to the beach, with either 12 or 24 geophones at 5-m (16-ft) spacing. Eight sediment cores were used to calibrate the velocity model.

Drilling for oil/gas and trawling on a continental shelf can cause damage to hard-bottom communities. Moving these activities offshore poses a threat to offshore communities. Habitat complexity is correlated with species diversity. The relationship of bottom relief to benthic species richness is not well understood in deeper communities.

The reservoir sedimentology and depositional environment of the Lower Cretaceous Alam El Bueib Formation in the Betty-1 well, Shoushan Basin, were investigated by studying lithofacies, petrography, and calcareous nannofossils. The sedimentary lithofacies indicate a fluvial to shallow-marine depositional environment.

Upward migration of brine because of pressurization resulting from injection is a risk of disposal of water produced with oil and geologic carbon storage. Analysis of the net production in each zone associated with oil production activities in the southern San Joaquin Valley, California, determined that net injection caused by disposal of water produced with oil occurred in zones above the shallowest zone with net production in several oil fields.

Numerical geochemical modeling was used to study the effects on pore-water composition and mineralogy from carbon dioxide (CO2) injection into the Pennsylvanian Morrow B Sandstone in the Farnsworth Unit in northern Texas to evaluate its potential for long-term CO2 sequestration.

Substrate relief is a common characteristic of hard-bottom offshore banks and is associated with benthic biodiversity. Earlier studies revealed varying relief associated with offshore mesophotic communities.

We report the results of analysis and interpretation of 19,278 predrilling groundwater samples from water wells in the Appalachian Basin for dissolved methane collected from 2009 to 2012 (11,309 samples from northeastern Pennsylvania and 7969 samples from a western area that included north–central West Virginia, eastern Ohio, and southwestern Pennsylvania).

We herein document temporal changes in dissolved and gaseous methane concentrations in 12 domestic water wells completed in Late Devonian clastic aquifers in northeastern Pennsylvania over time periods from 0.2 to 2 yr. Wells with initial methane concentrations regarded as low (<5 mg/L), moderate (5–15 mg/L), and high (>15 mg/L) were all used in our study for comparative purposes.

Net fluid production and pressure data were gathered to estimate the amount of CO2 storage space available and the potential for additional oil recovery using CO2-enhanced oil recovery (EOR) in the Phacoides sandstone, McKittrick oilfield, San Joaquin Valley, California.

One of the challenges confronting carbon dioxide capture and sequestration (CCS) in geologic media over extended periods of time is determining the caprock sealing capacity. If the pressure of supercritical carbon dioxide (scCO2) injected in the repository overcomes the caprock sealing capacity, leaking of scCO2 may enter other porous formations, compromising the storage formation, or even may go back to the atmosphere, and thus the process of sequestration becomes futile.
