Statistical data documenting past exploration success and failure can be used to inform the estimate of future chance of success, but this is not appropriate to every situation. Even where appropriate, past frequency is not numerically equivalent to future expectation unless the sample size is very large.

Kela-2 is a giant gas field with a proven reserve of 597 tcf in the Kuqa depression, northern Tarim Basin. Widespread overpressures have been encountered in the Eocene and Cretaceous sandstone reservoirs of the field, with pressure coefficients up to 2.1 from drill-stem tests and well-log data analysis.

The Lower Cretaceous McMurray Formation of northeastern Alberta hosts most of the bitumen resources of the Athabasca Oil Sands. Despite its importance, the sedimentary provenance and corresponding Early Cretaceous paleodrainage system associated with these fluvial deposits remain poorly understood. We collected 18 sandstone samples from five cored wells drilled in the McMurray Formation and analyzed these for detrital zircon uranium–lead (U–Pb) geochronology.

To date, most condensates and gases found in the Hammerfest Basin exist in distal, central basin settings, in traps with tight cap rocks of class 1 traps, whereas low-gas–oil-ratio (GOR) oils occur systematically in proximal basin settings, where cap rocks of class 3 traps prevail.

The Tan-Lu fault system in the central Liaodong Bay subbasin, Bohai Bay Basin, has complex structural characteristics, and its tectonism during the Cenozoic is an important factor in oil accumulation. Three-dimensional seismic data were used to document the structural features and evolution of the system.

Time is a precious commodity to us all, and is particularly treasured by geologists who have a unique relationship with the concept of time. Time is an especially precious commodity when it is given to the AAPG Foundation, in whatever increment.

A popular topic among educators and recruiters in our discipline is what geology, and the people who practice it, will look like in the future. It’s an interesting question when you consider the origins of our discipline, its pioneers and how both geology and its practitioners have evolved in the past 100 years.

Three outer continental shelf (OCS) oil and gas issues were prominent in 2015 policy debates and will continue in the policy limelight in 2016 as the federal government moves to release final versions of the permits, plans and rules.

The Ayoluengo field was the first commercial oil discovery in Spain and more than 50 years later remains the only onshore oilfield in the Iberian Peninsula. The field was discovered in 1964 and is still producing.

The main goal for shale resource characterization is usually the identification of sweet spots, which represent the most favorable drilling targets. Such sweet spots can be identified as those pockets in the target formation that exhibit high total organic carbon (TOC) content, as well as high brittleness. As there is no direct way of computing TOC using seismic data, we adopt indirect ways for doing so.

Papers in this publication describe case studies and workflows that demonstrate applied structural geology, covering a spread of topics including trap definition, fault seal, fold-and-thrust belts, fractured reservoirs, fluid flow and geomechanics. Against a background of evolving ideas, new data types and advancing computational tools, the volume highlights the need for structural geologists to constantly re-evaluate the role they play in solving industrial challenges.

Continental margins and their fossilized analogues are important repositories of natural resources. With increased availability of high quality geological, seismic and potential field data, imaging of these margins and their embedded sedimentary basins and magnetic rocks has reached new levels of refinement and definition, as illustrated by the examples described in this volume.

This volume includes contributions dealing with the origin of the magnetic minerals, and the application of MS as a palaeoenvironmental or palaeoclimatic proxy and also as a tool to provide astronomical calibration in order to improve the chrononology of selected time intervals.
