Résumé
The US Securities and Exchange Commission (SEC) late last year unanimously adopted revisions to its rules governing oil and natural gas reserves reporting, with those revisions aligned with and incorporating many of the definitions in the Society of Petroleum Engineers (SPE) Petroleum Resources Management System (PRMS). The revised rules will go into effect on January 1, 2010. The SEC oversees US securities exchanges, securities brokers and dealers, investment advisers, and mutual funds. Companies publicly offering securities on US exchanges are required to file regular disclosures to the SEC, concerning their securities and the scope, practices, condition, and risks of their businesses with respect to investors. The changes just adopted by the SEC, announced December 29, 2008, marked the first major revision of the commission's reserves-reporting rules since 1983. "In the more than a quarter century since the SEC last reviewed its rules in this area, there have been significant changes in technology that have increasingly limited the usefulness of current disclosures to the market and investors," said Christopher Cox, then-Chairman of the SEC. "These updates to the SEC rules will help ensure more meaningful and comprehensive disclosure of information that, even though it does not appear on a company's balance sheet, is of significance to investors in making informed investment decisions." Leo Roodhart, 2009 SPE President, praised the commission for modernizing the reporting rules. "The SEC is to be commended for updating the rules on oil and natural gas reserves reporting to reflect changes in technology, and for using the PRMS primarily as the basis for the technical changes," he said. "The updated rules recognize the importance of new technologies in making accurate and reliable estimates of oil and natural gas reserves as the industry develops resources in harsher environments, including ultradeepwater and the Arctic, as well as more unconventional resources." The PRMS was developed by SPE in collaboration with the World Petroleum Council, the American Association of Petroleum Geologists, and the Society of Petroleum Evaluation Engineers (SPEE). "SPE's Oil and Gas Reserves Committee is gratified that our work has served as a foundation for improving the information provided to investors and the public about the reserves controlled by public companies," said Delores Hinkle, SPE Oil and Gas Reserves Committee Chairperson. "The updated rules allow companies the flexibility to provide additional reserve information to the investing public and should result in better reserve estimates, due to the inclusion of the advanced technologies and evaluation practices now in use around the world."

Imitation des enseignantsNi prévalence calibrée, ni vérité terrain. Validation humaine à venir. Le volet Gemma est une étiquette directe du modèle pour chaque travail de la base, lue sur la notice réduite au titre. Le volet Codex est un classifieur appris des 10 348 étiquettes directes de Codex et calibré sur les taux pondérés de l'échantillon; les champs sans appui suffisant ne portent aucun appel Codex. Le mode candidate est l'union des deux volets; le consensus est leur intersection. Ces sorties portent le statut machine_predicted_unvalidated et ne sont pas des étiquettes humaines.
