Top 100 Oil and Gas Fields 2007

Appendix B Top 100 Oil and Gas Fields This appendix presents estimates of the proved reserves and production of the largest or top 100 liquids or gas fields as ranked by reserves or by production. The total liquids production and reserve data include both crude oil and lease condensate, and are labeled as liquids. The total gas production and reserve data is wet after lease separation. Although there is considerable grouping of field-level statistics within the tables, rough orders of magnitude may be estimated for the proved reserves and production of these fields. The tables rank the top 100 fields by production (Table B3 and Table B4) rather than by their reserves (Table B1 and Table B2). Some of the fields in the top 100 are operated by only one or two operators, therefore, the totals for proved reserves are combined in four groups top 10, top 20, top 50, and top 100 to avoid revealing company proprietary data. Many of these same fields are in each of the tables B1, B2, B3, and B4. The top liquids fields with the more recent discovery dates are typically located in the deep waters of the Gulf of Mexico Offshore or Alaska. The gas fields with the more recent discovery dates are normally located in the deep Gulf of Mexico Offshore, New Mexico, Colorado, and Wyoming.
