Unconventional Resources

Simon Chipperfield, SPE, Team Leader, Santos

“Geology drives technology,” and “the best solutions are multidisciplinary.”

Understanding the best way to develop an unconventional reservoir requires an
understanding of the rocks and a close interaction between the geosciences and engineering.


Reservoir Simulation

Martin Crick, SPE, Chief Petroleum Engineer, Tullow Oil

This year, there were approximately 200 papers on simulation to select from–and that is after a separate feature on history matching. So, the discipline continues to be active. A noticeable feature is the growing number of simulation papers that use different technology, in the broadest sense of the term–for example, using concepts from signal processing and electrical engineering to model subsurface flow or related phenomena. However, the dominant technology remains finite different representations of Darcy’s law, conservation of mass, and a fluid model.


RDD Director’s Blog – July 2012

On behalf of the Technical Directors (TD), I would like to draw your attention to a new article series in JPT called the Young Technology Showcase.  This showcase is part of the TD’s Technology Pipeline strategy and is focused on bringing young technology to the SPE membership.  Young refers to early in the technology life [...]

Enhanced Oil Recovery

Luciane Bonet-Cunha, SPE, Senior Reservoir Engineer, Petrobras America

Enhanced-oil-recovery (EOR) operations are what moves EOR processes from the laboratory to the field. They involve a series of activities, from a detailed planning stage to efficient application, consistent monitoring, and results analysis. When reviewing results from field pilots or full-field applications, it is noticeable that significant technical hurdles such as facilities, drilling and completion, and production-technology developments need to be overcome in order to deploy and run a successful EOR operation. Technology developments in water management, intelligent-well completions, and downhole innovation are key for EOR operations to achieve the expected increases in reserves.

History Matching and Forecasting

Régis Kruel Romeu, SPE, Senior Consultant, Petrobras Research Center (CENPES)

Many reservoir engineers dislike the very idea of automatic history match- ing applied to real full-field studies. They believe there is no artificial substitute for experienced reasoning, deep understanding of the reservoir mechanisms, and atten- tion to real-life practical aspects of the problem. Some use terms such as art and intu- ition. For them, even if computers long ago learned to play chess, computers will never be able to perform real-case history matching on their own or at least they are still too far from this achievement. Very often, during technical sessions, immediately fol- lowing an advanced mathematical presentation on history matching, someone in the audience makes his or her point about the limits of automatic approaches. To avoid disputes, experienced speakers prefer less pretentious expressions such as assisted or semiautomatic history matching.


High-Pressure/High-Temperature Challenges

Mike Payne, SPE, Senior Advisor, BP

Exciting operations are ongoing on the shallow-water US offshore continen- tal shelf (OCS) that will influence the entire high-pressure/high-temperature (HP/HT) community going forward. McMoran and their operating partners are actively drill- ing, evaluating, testing, and bringing to production several deep HP/HT plays. These prospects are named in the Treasure Island theme with identities such as Davy Jones, Blackbeard, and Lafitte. The Davy Jones 1 is in the completion phase, incorporating multiple Eocene Wilcox sands, and it represents the first 25,000-psi completion of its kind in the world. The Davy Jones 2 encountered confirmed pay and is progressing well. The original Blackbeard well was taken to 32,997-ft total depth, and operations on Blackbeard East have been permitted to 34,000 ft. As with Davy Jones, these wells represent substantial extensions to or step changes in current HP/HT technologies.
