It’s an unconventional world

Remaining Relevant – Not a Problem!

EMD members live in an unconventional and alternative world.

Now that may not sound like a positive thing, but I beg to differ.

It’s a new year, with a new EMD Executive Committee and president, and there is renewed interest in unconventional and alternative energy resources. This sounds somewhat like an oxymoron (think tight sands, heavy gas or synthetic natural gas) in the sense that what we refer to as unconventional and alternative implies that in an EMD world what we do is out of the ordinary and maybe not even relevant.

Several things have happened over the past several years that are causing EMD to be of more value – or as I would say, “relevant” – as we look ahead.

A national political push away from the conventional to the unconventional and alternative energy resources is a primary factor.

In review of the Annual Energy Outlook 2011 with Projections to 2035 published by the U.S. Energy Information Administration, it is stated that:

  • Shale gas production will continue to increase strongly, almost four-fold from 2009 to 2035.
  • The United States continues as the world’s leader in coalbed gas exploration, booked reserves and production. With a major increase of shale gas production, coalbed methane production is anticipated to remain steady to 2035.
  • Tight gas sands currently represent about 25 percent of the U.S. annual gas production.
  • Oil sand (bitumen) commercial production more than doubled during the last decade, and is expected to steadily increase over the next decade.
  • Although not expected to play a significant role in global production for another decade, oil shale is projected to increase two to potentially five-fold over the next five years.

Looking toward the future in regard to the alternatives, coal remains a significant component of the world’s production and energy consumption, albeit recently dropping slightly from supplying about 50 percent of the U.S. electrical generation down to 47 percent.

Recent technological developments and advances in clean coal, underground gasification and coal-to-liquids technology are anticipated to expand our reliability and dependency on coal’s role in the energy mix.

Coal production and consumption are anticipated to rise, and currently coal accounts for over half of the total energy use in the United States – and coal production is projected to increase by 21 percent to as high as 41 percent from 2009 to 2035.

Field tests continue in regards to gas hydrates with the goal of evaluating whether CO2 can be injected in a gas hydrates reservoir resulting in the production of methane while permanently sequestering CO2.

Industry interest should increase as sustained commercial production is achieved.

Nuclear power has re-emerged over the past decade and accounts for about 20 percent of our electricity – increased from 2003 to 2007 and decreased until mid-2010. Even with events following the March 11 Tohoku earthquake and tsunami, and resultant Fukushima incident, future trends are certainly upward, at coal’s expense, over the next 25 years.

Geothermal funding continues at the federal level with increases in funding anticipated.

Did I forget to mention that energy consumption is anticipated to go up across the board? You probably already knew that.


In summary, I am far from convinced that EMD is all about being out of the ordinary. In fact, EMD-related interests are becoming more mainstream in our daily dialogue – just look at the current interest among our colleagues and public in gas shale.

I am hopelessly optimistic for political leadership that will move us toward a national energy policy that is reasonable and economically and environmentally sound.

EMD will continue to play a significant and increasing role as interest grows in unconventional and alternative energy resources. This is clearly demonstrated by the increase in EMD membership (160 percent since March 2010), increasing numbers of individuals tapping into EMD’s website resources (EMD web portal activity up 100 percent in page views and 900 percent in visitors), and an increase in ballots cast in the recent election (up 145 percent from last year). There is no enthusiastic indifference here.

I am both excited and honored to have the opportunity to serve as the 2011-12 EMD president. As the new EMD Executive Committee develops and moves forward with our agenda for the upcoming year, our primary purpose is to continue to demonstrate and maintain our relevancy – and how we communicate not only to the choir but to all of our stakeholders.

These are exciting times for EMD and those involved in energy resources. The out of the ordinary is increasingly becoming the ordinary – extraordinary ordinary.

I invite you all to participate in this innovative and challenging venture.

Prolific hydrocarbon discoveries in the subsalt, commonly known as the “presalt,” section of Brazil and the conjugate African margin have created a business imperative to predict reservoir quality in lacustrine carbonates. Geothermal convection is a style of groundwater flow known to occur in rift settings, which is capable of diagenetic modification of reservoir quality. We simulated variable density groundwater flow coupled with chemical reactions to evaluate the potential for diagenesis driven by convection in subsalt carbonates.

Rates of calcite diagenesis are critically controlled by temperature gradient and fluid flux following the principles of retrograde solubility. Simulations predict that convection could operate in rift carbonates prior to salt deposition, but with rates of dissolution in the reservoir interval only on the order of 0.01 vol. %/m.y., which is too low to significantly modify reservoir quality. The exception is around permeable fault zones and/or unconformities where flow is focused and dissolution rates are amplified to 1 to 10 vol. %/m.y. and could locally modify reservoir quality. After salt deposition, simulations also predict convection with a critical function for salt rugosity. The greatest potential for dissolution at rates of 0.1 to 1 vol. %/m.y. occurs where salt welds, overlying permeable carbonates thin to 500 m (1640 ft) or less. With tens of million years residence times feasible, convection under these conditions could locally result in reservoir sweet spots with porosity modification of 1% to 10% and potentially an order of magnitude or more in reservoir permeability. Integrating quantitative model–derived predictive diagenetic concepts with traditional subsurface data sets refines exploration to production scale risking of carbonate reservoir presence and quality.

When evaluating paleosystems, there will always be a shortage of data constraints and a surplus of plausible geological scenarios for a basin evaluation. Modelling paleosystems with constraints from the modern has been used as a successful approach to better understand petroleum systems.
