estimate of fair market value. These estimates were prepared in accordance with the definitions and regulations of the U.S. Securities and Exchange Commission (SEC) and, with the exception of the exclusion of future income taxes, conform to the FASB Accounting Standards Certification Topic 932, Extraction Activities – Oil and Gas.
Reserve and cash flow summary projections for total proved reserves by category, a one-line summary for total proved reserves by category, a cash flow and one-line summary of reserves by region, field and reserve category have been delivered separately to Contango in support of this report.
Oil and NGL volumes are expressed in thousands of stock tank barrels (MBBL). A stock tank barrel is equivalent to 42 United States gallons. Gas volumes are expressed in millions of standard cubic feet (MMCF) as determined at 60o Fahrenheit and the legal pressure base for the specific location of the gas reserves.
Cobb & Associates reviewed 100 per cent of the properties included in this report. This report, which was prepared for Contango’s use in filing with the SEC and will be filed with Contango’s Form 10-K for fiscal year ending December 31, 2020 (the “Form 10-K”) and covers 100 percent of the total company present value discounted at ten percent (PV10) presented in Contango’s Form 10-K. All assumptions, data, methods, and procedures considered necessary and appropriate were used to prepare this report.
DISCUSSION
The Contango properties are divided into five regions: Central Oklahoma, Offshore, Onshore, Western Anadarko, and West Texas. The Central Oklahoma and Western Anadarko properties are located in Oklahoma and north west Texas and 47.5 and 12.5 percent, respectively, of the total proved discounted present value are attributable to these properties. These properties were acquired from White Star Petroleum and Will Energy in late 2019. The onshore properties are located in Louisiana, Mississippi, east Texas, and Wyoming and make up 5.3 percent of the total proved discounted value. The offshore properties are located in Louisiana state and federal waters of the Gulf of Mexico and contribute 7.5 percent of the total proved discounted value. The west Texas properties are located in Pecos County in the Delaware Basin and provide 27.2 percent of the total proved discounted value.
Reserve estimates were prepared using generally accepted petroleum engineering principles and practices. The method, or combination of methods, utilized in the study of each property or reservoir included an assessment of the stage of reservoir development, quality of data, and length of production history. Geologic and engineering data was obtained from Contango, public sources, and the non-confidential files of Cobb & Associates.
Performance data through December of 2020 was used to forecast reserves for all producing properties where available. Reserve classification was based on the status of each well as of January 1, 2021 for operated wells, and on the most recently available information for non-operated wells.
For most regions in the report, the PDP reserve estimates were based on decline curve analysis. Some of the properties have produced for only a short period of time and did not exhibit an identifiable performance decline trend. In these cases, reserve estimates were based primarily on geological interpretation, mapping, and analogy to offset producers. Past performance, and offsetting performance data were used to estimate behind pipe and undeveloped reserves. Fields where additional analysis or methodology was used for the reserve assignments are discussed in more detail. These fields include Eugene Island 11 and properties in west Texas.
