The Value of Exploration

This edition of EXPLORER began with President Paul Weimer presenting a detailed analysis of membership trends in the Association. It’s an important topic because these trends are harbingers of AAPG’s future – and they should force serious thinking about how we recruit and retain tomorrow’s members.

That may look significantly different than it does today.

But I’d like to close this month’s issue with some thoughts on one of the core aspects of our science and profession: Exploration. It’s a fundamental human drive that has attracted past generations into petroleum geology.

I’m currently reading Space Chronicles: Facing the Ultimate Frontier by Neil deGrasse Tyson, an astrophysicist and director of New York’s Hayden Planetarium. Tyson regularly lectures and hosts science television programs to promote science literacy – and, like Carl Sagan a generation ago, he is an unabashed promoter of space exploration.

Despite its high price tag, Tyson argues that the value of space exploration is twofold:

  • First, it advances science and technology in many disciplines, often serendipitously.
  • Second, bold challenges – such as putting a man on the moon – inspire the best and brightest to pursue science and engineering careers.

Achieving something so audacious is inherently motivating. Absent such a goal, it is little wonder that in the past decade so many quantitative Ph.Ds. chose instead to pursue careers in financial engineering.

Exploration doesn’t happen in a vacuum (except for space exploration, of course). There are factors that drive humans to explore, and Tyson suggests three:

♦ Military competition.

Space exploration has its roots in the Cold War between the United States and the Soviet Union. It is no accident that nearly all of NASA’s astronauts were military aviators. And only one scientist ever walked on the moon: Apollo 17’s Harrison “Jack” Schmitt, a geologist and AAPG Honorary Member.

♦ Honor and glory.

There are bragging rights to being first to explore or achieve something. As a boy I was inspired by mountaineer Reinhold Messner’s feats of scaling Mt. Everest – the highest point on Earth – alone and without oxygen. To an armchair mountaineer that is a superhuman accomplishment.

More recently, explorer and filmmaker James Cameron dove the Marianas Trench – the deepest point on Earth – and demonstrated that we still have much to explore on this planet.

♦ Commercial.

Finally there are the commercial interests that drive exploration. That certainly characterized early traders and explorers – looking for faster or better paths to obtain goods, or deliver them to market. Finding and producing natural resources fits this category, as does the emerging commercial space industry looking to take away the government monopoly on space travel that has existed to present.

The commercial reward of finding and developing oil and natural gas certainly fuels the exploration drive of many AAPG members. But so does the recognition that comes from finding and communicating new scientific discoveries and breakthroughs. It’s all exploration.

Fact is, our profession and industry are advancing the frontiers of science. And we’re doing so to meet the daily energy needs of a growing global population.

Ensuring an affordable and plentiful global energy supply is an audacious challenge. Energy is the foundation of modern society and enables mankind to explore the stars and the depths.

Can we craft a compelling narrative to attract the best and brightest into the energy geosciences, and to foster that spirit of exploration in the next generation?

It starts with that dream and desire to do important work.

“There are a lot of things I have to do to become an astronaut,” says four-year-old Cyrus Corey in Space Chronicles. “But first I have to go to kindergarten.”

That’s a great plan, Cyrus. And take a class in geology the first chance you get.

This article concentrates on the question, Which parameters govern recovery factor (RF) behavior in channelized turbidite reservoirs? The objective is to provide guidelines for the static and dynamic modeling of coarse reservoir-scale models by providing a ranking of the investigated geologic and reservoir engineering parameters based on their relative impact on RF. Once high-importance (H) parameters are understood, then one can incorporate them into static and dynamic models by placing them explicitly into the geologic model. Alternatively, one can choose to represent their effects using effective properties (e.g., pseudorelative permeabilities). More than 1700 flow simulations were performed on geologically realistic three-dimensional sector models at outcrop-scale resolution. Waterflooding, gas injection, and depletion scenarios were simulated for each geologic realization. Geologic and reservoir engineering parameters are grouped based on their impact on RF into H, intermediate-importance (M), and low-importance (L) categories. The results show that, in turbidite channel reservoirs, dynamic performance is governed by architectural parameters such as channel width, net-to-gross, and degree of amalgamation, and parameters that describe the distribution of shale drapes, particularly along the base of channel elements. The conclusions of our study are restricted to light oils and relatively high-permeability channelized turbidite reservoirs. The knowledge developed in our extensive simulation study enables the development of a geologically consistent and efficient dynamic modeling approach. We briefly describe a methodology for generating effective properties at multiple geologic scales, incorporating the effect of channel architecture and reservoir connectivity into fast simulation models.

This article reviews the mechanisms of shale gas storage and discusses the major risks or uncertainties for shale gas exploration in China. At a given temperature and pressure, the gas sorption capacities of organic-rich shales are primarily controlled by the organic matter richness but may be significantly influenced by the type and maturity of the organic matter, mineral composition (especially clay content), moisture content, pore volume and structure, resulting in different ratios of gas sorption capacity (GSC) to total organic carbon content for different shales. In laboratory experiments, the GSC of organic-rich shales increases with increasing pressure and decreases with increasing temperature. Under geologic conditions (assuming hydrostatic pressure gradient and constant thermal gradient), the GSC increases initially with depth due to the predominating effect of pressure, passes through a maximum, and then decreases because of the influence of increasing temperature at greater depth. This pattern of variation is quite similar to that observed for coals and is of great significance for understanding the changes in GSC of organic-rich shales over geologic time as a function of burial history. At an elevated temperature and pressure and with the presence of moisture, the gas sorption capacities of organic-rich shales are quite low. As a result, adsorption alone cannot protect sufficient gas for high-maturity organic-rich shales to be commercial gas reservoirs. Two models are proposed to predict the variation of GSC and total gas content over geologic time as a function of burial history. High contents of free gas in organic-rich shales can be preserved in relatively closed systems. Loss of free gas during postgeneration uplift and erosion may result in undersaturation (the total gas contents lower than the sorption capacity) and is the major risk for gas exploration in marine organic-rich shales in China.
