Two of the 10 Miocene sands in the Tubular Bells oil field, offshore Gulf of Mexico, are connected. Highly saline water from the deep Louann salt and dissolution of nearby salt account for the large variation in formation water chemistry as determined by isotopic and chemical analysis.

This study uses hydrochemistry and environmental isotopes to quantify flowback volumes for fracturing fluids injected into the Qusaiba hot shale, Saudi Arabia. Less than 10% of the injected fluids were recovered while nearly 80% of the recovered fluid was formation water.

The δ18O values of zoned dolomite-ankerite cements within shaly sandstone beds decrease with depth of burial in the Upper Cambrian Eau Claire Formation of the Illinois Basin. This trend is largely consistent across the basin as determined through secondary ion mass spectrometry.

Carbonates of the Frontier Formation, Uinta Basin, contain certain physical, petrographic, and isotopic characteristics best explained by the presence of sea-floor methane seeps. These seeps record episodes of hydrocarbon generation and demonstrate a potentially viable petroleum system.

Zheng et al. provide evidence based on facies, geometry, and sandbody orientation and thickness that the incised-valley fill mentioned by Jiang et al. (2012) is in actuality a barrier island. Jiang et al. offer additional proof based on core, well logs, thin section, field study, seismic analysis, and well correlation to reinforce their original interpretation.

My participation in AAPG activities has always been a source of wonderful memories. To this day, I strongly believe that my active involvement in AAPG YP Chapter leadership was key to obtaining scholarships and advancing my geoscience studies.

As the United States Strategic Petroleum Reserve approaches its 40th birthday and the world is awash in excess oil, the U.S. Department of Energy and Congress are taking a serious look at the reserve and its almost 700 million barrels of crude oil stored in 62 salt caverns in Texas and Louisiana.

Calgary, site of the 2016 AAPG Annual Convention and Exhibition, has been regarded to be generally free of natural hazards … until the summer of 2013, that is.

This work demonstrates a modern workflow that directly extracts high-resolution, large-scale fracture networks from seismic inversion-based structural attributes. The workflow is successfully applied to a thrust-belt controlled, lower Triassic, siltstone reservoir in the Montney Formation of the Farrell Creek area in northeast British Columbia to extract a 3-D fracture network orthogonal to the primary stress direction.

Methane clathrate (CH4·5.75H2O) or (4CH4·23H2O), also called methane hydrate, hydromethane, methane ice, fire ice, natural gas hydrate, or gas hydrate, is a solid clathrate compound (more specifically, a clathrate hydrate) in which a large amount of methane is trapped within a crystal structure of water, forming a solid similar to ice. Originally thought to occur only in the outer regions of the Solar System, where temperatures are low and water ice is common, significant deposits of methane clathrate have been found under sediments on the ocean floors of the Earth.

These datasets depict the location and extent of oil and gas fields and pools across Pennsylvania, provide basic reservoir characterization data at the pool level (to the extent possible), and provide representative well-specific data to chronicle the evolution of the petroleum industry from the time of Drake’s well (Titusville, 1859) through the end of calendar year 2011.

The Rotliegend aeolian sandstone of Early Permian age forms the main producing horizon in the Southern North Sea gas province. Currently [1990] some 30-40 fields have been identified in a broad zone measuring 450 by 100 km stretching from the English coast, through the UK and Dutch sectors of the North Sea and on to The Netherlands and West Germany. North Sea field sizes range between 10-300 Bcm (0.3-10.5 TCF). Ultimate recoverable reserves for the province are estimated at some 4250 Bcm (150 TCF).
