ANNUAL STATISTICAL REVIEW 2020

Preface

Oil and Energy Trends: Annual Statistical Review is intended to bring together in a convenient

form the salient quantitative data on the world-wide oil industry during the recent years. Most of

the tables give figures for 2019, but in some cases such up-to-date information is not yet avail-

able; in others, it is only available on a partly estimated basis and is included without further

distinction because it is felt that the margin of error is small.

The data are drawn from a great variety of sources: governmental, industrial, and international

organizations. In a few cases, there are inconsistencies in the data because of differences

between sources. They arise largely from different definitions used for what is ostensibly the

same subject-matter.
