Check the appropriate box below if the Form 8-K filing is intended to simultaneously satisfy the filing obligation of the registrant under any of the following provisions (see General Instruction A.2. below):

The Company is filing this Current Report on Form 8-K for the purpose of providing certain production and operational updates.

In late February and March of 2013, we began to experience production declines in our Flipper wells, all of which are located in our Yegua Trend in East Texas. We attributed this decline to scale and sand production in the wellbore, which is a common experience in this formation, and accordingly designed a routine workover program to deal with this issue which had proved successful on other wells. However, in mid-May, we determined that the casing in the Flipper #1 well had collapsed, and subsequently we were able to confirm that the casing had collapsed in all of the Flipper wells. Production declined rapidly, and eventually the Flipper #1, #2, and #3 wells went offline. Production on the Flipper #4 well was substantially reduced. The cause of the casing failure is believed to be the result of the collapse of the formation resulting from the normal decrease in pressure as the field was produced.

In recent weeks, we have developed a program to sidetrack the Flipper #3 well with production estimated to begin in late July, and subsequent to the Flipper #3 sidetrack, we intend to drill a replacement well for the Flipper #1 well. An Authorization for Expenditure, or AFE, is being prepared for drilling a replacement well to the Flipper #2 well in the fourth quarter of 2013.

As a result of the Flipper wells going offline, RAAM’s total production during the first and second quarters of 2013 was approximately 10,434 Boepd and 8,718 Boepd, respectively, as compared to average [net] daily production during the year ended December 31, 2012 of 11,399 Boepd.

We expect production to increase in the third quarter of 2013, as these new Flipper wells and other wells are drilled and brought into production, but we are not prepared to give specific guidance for third quarter production.
