Delegates Voice Division Article By Michael Jacobs

DEG is a group of very diverse geoscientists and professionals who have a very wide range of interests and specialties. Most members are geoscientists by education, but not all, and many of us are involved working on the fringes of traditional oil and gas company roles as hydrologists, hydrogeologists, geochemists or maybe as near surface geophysicists. We apply the tools of our trade in the energy industry in many different ways.

Oil, Gas Take Hits on Proposed Budget

The president has proposed to repeal a series of oil and natural gas tax “preferences.”

DEG Covers Broad Interest Spectrum

Every now and then I get the opportunity to talk about the AAPG, and in particular the Division of Environmental Geosciences – but until now I have not had the opportunity to discuss the DEG with such a wide audience.

'Climategate' and the Ethics of Science

COMMENTARY: Over the last century science has played an ever-increasing role in the lives of all people. Science has increased life expectancy, improved our standard of living, dramatically speeded communications and made us a space-faring people, to cite only a few examples.

Divisions to Cooperate on Renewables

It was refreshing to meet recently with Frank Walles, the Energy Minerals Division president, and Michael D. Campbell, EMD president-elect, to discuss the great opportunities that exist to help the AAPG membership stay abreast of developments within the renewable energy arena and how they may affect the membership and the energy industry in general.

Authorizing and Appropriating

Congress passes many laws – that is its principal function as outlined in Article I of the U.S. Constitution. It also controls the nation’s purse strings, deciding how tax revenue collected from the people will be spent for the people.

Shale Play Extends to Canada

Northern exposure: That gush of excitement you may feel may be coming from Canada – specifically, eastern Canada – and it’s all because the Utica shale play there may be as big as the Barnett.

CO2 Sequestration in Spotlight

It seems like everywhere I go lately everyone wants to debate issues like global warming, climate change, greenhouse gas (GHG) emissions and cap-and-trade versus a revenue-neutral carbon tax system.

Geoscience: Now More Than Ever

I recently had the pleasure of participating in an E&P company’s internal reservoir characterization technology forum. The eclectic meeting covered topics ranging from the implications of peak oil to ways to improve recovery factors.

Lots of Potential, Lots of Hurdles

As North America tries to obtain energy security it will have to rely on more unconventional resources to fulfill its energy needs over the next decades – and balanced with that is the need for stewardship of the environment and the need to develop more sustainable strategies.

US Energy Forecast: Even Cloudier Than Usual

It isn’t news to anyone that prediction is difficult, especially when it’s the future (as a great man once said). Uncertainty and unpredictability are just a part of the job of tracking and predicting the future supply and demand of energy. That being the case, when energy analysts say that the current level of uncertainty is particularly high, it might be easy to dismiss it as a “dog bites man” story. It isn’t.

Impact of Reprocessing Seismic Data

Advancements in processing and imaging techniques have continued over the last several decades, which have gradually improved the quality of the processed surface seismic data. When the quality of the existing seismic data is not adequate to perform an interpretation task reasonably, then the interpreter looks for other options. Is it feasible to acquire a new survey? In the absence of an improved survey, will reprocessing of seismic data be a good option?

Introducing the New EXPLORER, New Digital Newsletters

Perhaps you did a double take pulling the April issue of EXPLORER from the mailbox. What is this? If you joined AAPG in the last 40 years, you’ve only known EXPLORER in its long-standing tabloid format. It worked well for many years as our advertisers – particularly seismic companies – loved the large format and the ability to display their data on a sweeping canvas. For readers, it was a little more awkward.

Natural Increase of Oil Column Buoyancy and the Instability of Caprock Seals

A new type of buoyancy model can be used to understand the source of residual oil zones, both thick and thin, to help determine the likelihood that economically viable recoverable oil resides in transition zones of imbibition reservoirs. Application of a buoyancy and breech model will fill a void in reservoir characterization. It will help distinguish between TZs and ROZs, the first of which allows application of primary and secondary (waterflooding) oil recovery methods and the second of which requires more difficult CO2-enhanced oil recovery projects.

Casablanca: Spain's Biggest Oil Field

The Casablanca oil field, discovered in 1975 and located on the Mediterranean shelf edge, has been greatly significant in the world’s offshore oil industry activity, besides being by far the biggest oil field in Spain.
