Reserves/Asset Management-2014

The realization that we should not look at any individual aspect of how to estimate unconventional reserves and resources properly without considering its place in the project life cycle reflects a maturity within the industry.

When I joined the petroleum industry almost 40 years ago, integration of the various aspects of our work seemed like something out of a science-fiction movie. As an industry, we have come a long way. More than half of the roughly 120 abstracts of papers presented this year in the category of reserves and asset management addressed integration in some fashion. Mercifully, advances in recording instruments and computers have released the handcuffs of limited data and cumbersome calculations. I fear the handcuffs may have been replaced by data overload, but I will leave that discussion for my colleagues who present the information-management section in this magazine.

One popular theme was something we sometimes lose sight of: how to integrate investments and production into portfolios without destroying value. Both technical and planning advances have been addressed at length in the presentations from which the papers summarized and those recommended for additional reading were selected.

Optimization was also a very popular topic among the papers I reviewed. With the current emphasis on the development of unconventional properties, both the technical and economic optimization of well spacing and stimulation techniques was addressed in numerous papers. Several authors used different approaches, but most came to the same conclusion: The balance between net present value and overdrilling or fracturing to maintain rate is a tricky one.

In addition to the highly technical discussions, there were several papers addressing the maturing regulatory environment. Because the Modernized SEC Rules, Canada’s NI-51, and the SPE Guidelines for Application for Petroleum Resources Management System have been around for several years now, there were numerous papers on the handling of specific situations within those regulations. Resource estimation and reporting continue to be topics of much interest, specifically in unconventional reservoirs.

I always enjoy reviewing papers for this section. When I sat back to reflect on what would be the most useful information to present, it occurred to me that the theme of growth and maturity was reflected in almost all of the papers. Our understanding of how to estimate unconventional reserves and resources properly has definitely grown over the last few years. Our realization that we should not look at any individual aspect of our business such as drilling or production without considering its place in the project life cycle, including its economics, reflects a maturity within the industry, as does learning how to reflect our assets effectively in a changing regulatory environment. It is satisfying to see the depth and strength of the advances in our industry, no longer the stuff of science fiction.
