This paper presents data and interpretations on presalt stratigraphy and depositional facies in the Kwanza Basin, offshore Angola, which appear similar to the presalt systems in Brazil. Lacustrine sedimentation has resulted in many unusual carbonate and chert facies.

Four outcropping structures representing different stages of fold development in the Cardium sandstone, central Alberta, allow the evolution of fracture development to be constructed and linked to folding history. They provide a unique opportunity to assess different stages in the fracture system.

This paper presents a geometrically based method for calculating the shear-induced hydraulic aperture as a function of horizontal stress, orientation of fractures with respect to the normal stress, and fracture spacing in fractured pavements.

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.

Differences in hydrocarbon chemistry between the western and eastern portion of the Tazhong Uplift, Tarim Basin, China, are mainly the result of thermochemical sulfate methane with sulfate contact ion pairs in the west and thermal cracking of liquid hydrocarbon in the east.

Conditions may presently be far from ideal in our industry, but they will get better. Downturns are always followed by recovery and growth. We take these times to learn, develop and improve, while at the same time, hanging on for dear life. Every now and then though, we need to stop, take a breath, forget our troubles and have a good time.

Even though oil prices are up from their January lows, many people are focused on the current economic hardships, business bankruptcies and layoffs, and the question naturally arises – was the boom worth it?

In 1953, a subsidiary of British Petroleum obtained an oil concession of 31,000 square kilometers off the coast of Abu Dhabi. It would later become an important discovery, revealing the potential of Cretaceous carbonate reservoirs in the region.

Interpolation of seismic data is an important application in exploration seismic signal processing. The need for interpolation on incomplete data may be due to acquisition limitations, economic constraints or regularizing of merged data with a variety of shooting parameters from different vintages.

This volume contains 10 chapters on coal-bearing strata of Carboniferous through Tertiary age and is based on a special session taht was held at an AAPG Annual Meeting in New Orleans. Contributors have employed a multitude of approaches ranging from basin analysis to plant taphonomy to support a variety of views on the sequence stratigraphy, paleoclimate, and tectonics of coal-bearing strata.

The 17 papers in this volume cover topics such as a method to estimate the amount of oil/gas accumulation using the concept of equivalent grain size in seal rock, and oil/gas migration to and spill-point geometry of petroleum traps; two case studies of fault seal assessment applied to normal faults in Tertiary clastic reservoirs in offshore Sarawak and offshore Gulf of Thailand; and physical analog studies of the development of extensional faults.

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.

The House Natural Resources Committee recently held a hearing to discuss energy development in the Mancos shale formation of the Piceance basin, which is a geographic area that spans Colorado and Utah and much of the resource is located on federal lands. The purpose of the hearing was to highlight the release of a recent U.S. Geological Survey (USGS) assessment which found that the Mancos shale has a large volume of recoverable energy resources.
