Item 8.01 Other Events.

In connection with the filing of an amendment to a Registration Statement on Form S-1, Constellation Energy Partners LLC received an independent engineer reserve report dated September 26, 2007 reporting that oil and gas proved reserves for properties acquired in the merger with AMVEST Osage, Inc. were 71 Bcfe as of July 25, 2007, the closing date of the merger (based on a NYMEX price of $5.655/MMbtu for gas and $72.50/bbl for oil as of July 25, 2007).

The data above represents estimates only. Reserve engineering is an inherently subjective process of estimating underground accumulations of oil and natural gas that cannot be measured exactly. The accuracy of any reserve estimate is a function of the quality of available data and engineering, geological interpretation and judgment. Accordingly, reserve estimates may vary from the quantities of oil and natural gas that are ultimately recovered. Please read the “Risk Factors” section in the Company’s Securities and Exchange Commission filings and elsewhere in those filings for factors that may cause actual quantities recovered to differ materially from estimated reserves.
