Iraqi article ‘disappointing’

The article “Oil reconstruction in Iraq: progress and challenges” (OGJ, Dec. 19, 2005, p. 26) was a very disappointing article on an obviously important subject.

The article failed to address current news reports that Iraqi oil exports are at the lowest level since before the war began. It seems hard to ignore such a fact in an article purporting to describe reconstruction progress. Similarly, the article made no reference to the world-scale challenges Iraq faces in finding and developing much of the reserves they have claimed to have for several years. If the authors are aware of the advanced stage of depletion and consequent production decline in such major fields as Kirkuk and Basrah, for inexplicable reasons, they chose not to identify reserve depletion as a challenge.

If there is an appropriate place for publishing the material in this article, perhaps it would be in a foreign affairs journal in keeping with the reported expertise of the authors. I hope the Oil & Gas Journal will return to its usual high standards of publishing only factual and meaningful news of the industry.

Subject: “DMR technique improves tight gas porosity estimate,” OGJ, Dec. 19, 2005, pp. 54-59.

We regret that the scope of our recent article on application of the density-magnetic resonance (DMR) method for evaluation of tight gas sandstones appears to be misleading. It has been brought to our attention that our article discussed the DMR equations and method in detail without acknowledging the publications that first introduced the DMR equations and method.1 2
