Thermochemical sulfate reduction (TSR) is complex and cannot be simply represented. The application of three-dimensional reactive transport modeling presented in this paper is a good example of how such an approach to investigate TSR can be used prior to drilling.

A modelling approach is presented in which surfaces are used to represent geologic heterogeneities that control the spatial distribution of reservoir rock properties. This method offers improved results in mm to cm scale intercalations of mudstone and sandstone.

This sequence stratigraphic study in the Neuquén Basin, Argentina, contributes to the understanding of the relationship between organic matter, clay minerals, facies, stacking patterns, and relative sea-level changes in this exceptional shale-oil and shale-gas unconventional reservoir.

A suite of surface-based models of heterolithic, cross-bedded tidal sandstones has been investigated via flow simulation in order to calculate effective permeability. Effective permeability is highly anisotropic and decreases as the mudstone fraction increases.

This paper presents new data for the Rub' Al-Khali Basin, Saudi Arabia, constraining the age, depositional environment, petrography, regional correlation, and fluid system of these Middle Jurassic silicic sands. This play is independent of underlying and overlying systems.

With less than 30 days until the June 18 HoD Annual Meeting, and this Delegates’ Voice to be published before the convention, we wanted to summarize concerns for the two amendments offered by the EC and/or HoD leadership, and champion the two amendments that 60-plus members petitioned to be passed.

In last month’s DV a few of our members submitted a letter in opposition to the proposed amendment to AAPG’s bylaws concerning the Advisory Council (AC), to be voted upon at the HoD meeting in Calgary. This amendment, if approved, will allow each Section, Region and Division to have a voting representative on the AC.

Rarely in the recent history of House of Delegates meetings has a more profound initiative come out of the annual meeting. Beginning at the HoD meeting in Denver, Bob Shoup instituted an initiative to simplify the Bylaws in an effort to make them more readable and understandable.

In this column you will find a link to “v.13” of the reformatted constitution and bylaws. There have been numerous sub-versions within the major versions, so it is no exaggeration to say that there have been over two dozen versions of the document that have been thoroughly vetted by delegates, committees and leadership over the past year.

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.

On May 12 the Environmental Protection Agency (EPA) issued its final rule that aims to reduce emissions from new and modified oil and natural gas facilities: New Source Performance Standards for methane and volatile organic compounds (VOC). At the same time EPA announced its plan to apply the rule to existing wells and facilities, but first EPA needs additional information about the size and scope of the oil and natural gas industry as well as emissions data. A planned Information Collection Request (ICR)  would require the operator of every onshore production facility to report on wells and facilities, throughput and emissions.
