Depositional and postdepositional processes of an oil-shale analog at the microstructure scale: The Lower Cretaceous Agrio Formation, Neuquén Basin, northern Patagonia

Lenticular fabric and calcareous nannofossils suggest high carbonate productivity in the water column and algal-derived organic matter of the Agrio Formation. Evaluation of depositional and postdepositional controls on the resultant microstructure will result in a better understanding of potential target intervals.

Quantitatively predicting the thermal maturity of oil trapped in fluid inclusions based on fluorescence and molecular geochemical data of oil inclusions in the Dongying depression, Bohai Bay Basin, China

Fluorescence colors of oil inclusions may be good indicators of thermal maturity in oil systems charged from oil-prone source rocks. This makes it possible to quantitatively predict the thermal maturity of oil inclusions based on their fluorescence characteristics.

Toward a better understanding of northern Alaska’s petroleum systems: Deconstructing the Barrow arch

Several distinct geologic elements in northern Alaska have been referred to as the Barrow arch in the literature over the last 60 years. This report is an effort to more sharply define these elements and to introduce new terms that better define them.

Architectural analysis of subsurface meander-belt sandstones: A case study of a densely drilled oil field, Zhanhua sag, east of Bohai Bay Basin

The sandstones of the Guantao Formation in the Gudong oil field consist of meandering river facies. Five channel stories were identified. The initial story was mostly developed in the middle of the meander belt axis, while the last story was deposited near the margin of the meander belt.

Source potential and reservoir characterization of the Cambay Shale, Cambay Basin, India: Implications for tight gas and tight oil resource development

The kerogen type and maturity level along with the high clay content and poor to moderate brittleness indicates low fracability, thereby restricting the production potential of the Cambay Shale for tight gas or oil exploration.

Constraining coalbed methane reservoir petrophysical and mechanical properties through a new coal structure index in the southern Qinshui Basin, northern China: Implications for hydraulic fracturing

The structurally constrained properties of a coalbed methane reservoir from the Qinshui Basin in northern China have been investigated using a coal structure index. This index is proposed as a new quantified approach for the evaluation of the coal deformation degree.

Seal failure assessment of a major gas field via integration of seal properties and leakage phenomena

This paper presents an interpretation of a large leakage zone above a gas field in Australia. The authors conclude that the mode of leakage in this specific setting is consistent with a sudden increase of aquifer overpressure. Two alternative models for seal failure are suggested.

High-resolution hyperspectral-based continuous mineralogical and total organic carbon analysis of the Eagle Ford Group and associated formations in south Texas

Hyperspectral imaging, used to generate mineral maps of the Eagle Ford Group, is a powerful tool for studying textural and fabric relationships because it detects and highlights the major mineralogical changes that occur between depositional beds and among depositional features.

Evidence of rift segmentation and controls of Middle to Late Jurassic synrift deposition in the Ryggsteinen ridge area, northern North Sea

This study integrates well and seismic data to present evidence of rift segmentation through multiple episodes of rifting and preexisting structure reactivation. It controlled the middle to late Jurassic synrift deposition in the Ryggsteinen ridge area in the northern North Sea.

On the dolomite reservoirs formed by dissolution: Differential eogenetic versus hydrothermal in the lower Permian Sichuan Basin, southwestern China

The lower Permian Qixia Formation in northwestern Sichuan Basin formed by differential eogenetic karstification and hydrothermal dissolution of grain dolomites. This study provides an improved understanding of the origins and complexity of dolomite reservoirs formed by dissolution.

Quantitative assessment of the runoff index in an urbanized watershed

Urbanization modifies the natural water cycle. In this study, a weighted-rating multicriteria analysis was adopted to quantify the runoff index and to assess the impact of urbanization on the water cycle.

Hydrogeochemical controls on brackish groundwater and its suitability for use in hydraulic fracturing: The Dockum Aquifer, Midland Basin, Texas

To better understand controls on the origin and evolution of brackish groundwater, the hydrogeochemistry of brackish groundwaters was studied within the Triassic Dockum Group across the Midland Basin in Texas. The suitability of Dockum Aquifer water for use in hydraulic fracturing fluid was examined because the area overlies the largest and most productive tight oil province in the United States.

Facies associations and chemostratigraphy of the Lower Cretaceous Kurnub Group and their boundaries, King Talal Dam section, northwestern Jordan

Integrated petrographic and chemostratigraphic studies have enabled the identification of sequence boundaries, sequence stratigraphy, and their system tracts for the Lower Cretaceous strata of the Kurnub Group (Jordan); the latter is underlain by the Jurassic (Callovian) strata and overlain by the Cretaceous (Cenomanian).

Groundwater resources evaluation using geospatial technology

Groundwater is water located beneath the ground surface in soil pore spaces and in the fractures of lithologic formations. The advent of remote sensing and geographic information systems (GIS) has opened up new vistas in groundwater prospect evaluation, exploration, and management.

Strontium isotopes as a potential fingerprint of total dissolved solids associated with hydraulic-fracturing activities in the Barnett Shale, Texas

A dramatic increase in unconventional drilling that utilizes hydraulic fracturing to extract oil/gas over the past decade has led to concern over handling and management of produced/flowback water (PFW; hydraulic-fracturing wastewater) because the potential exists for its accidental release into the environment.

High-resolution satellite imagery applied to monitoring revegetation of oil-sands-exploration well pads

To achieve reclamation certification, oil-and-gas operations in Alberta, Canada are required to monitor the revegetation of idle well pads that no longer support operations. Currently, monitoring is completed by oblique, helicopter-collected photography and on-the-ground field surveys.

Geothermal energy potential of the Western Canada Sedimentary Basin: Clues from coproduced and injected water

Development of geothermal energy in sedimentary basins is an attractive option given the availability of data from the oil and gas industry. Previous geothermal studies in sedimentary basins have focused on temperatures and petrophysical properties.

State of stress in the Illinois Basin and constraints on inducing failure

The stress regime in the Illinois Basin was investigated to assess how the rock column might respond to the injection of fluids, including coproduced formation brines and supercritical CO₂.This response is a concern because injection practices could increase pore fluid pressure and potentially induce seismicity.

Methods and challenges to locating legacy wells in western Pennsylvania: Case study at Hillman State Park

This study demonstrates the application of aeromagnetic surveys for locating late 1800s-era oil and gas wells in Hillman State Park. The study area in southwestern Pennsylvania offered several unique challenges to locating legacy wells.

Structural architecture of the Farnsworth oil unit: Implications for geologic storage of carbon dioxide

Surface and airborne gas monitoring programs are becoming an important part of environmental protection in areas favorable for subsurface storage of carbon dioxide. Understanding structural architecture and its effects on the flux of fluids, specifically CO₂ and CH₄, in the shallow subsurface and atmosphere is helping with designing and implementing next-generation monitoring technologies, including unmanned aerial vehicles (UAVs).
