3. Regarding your response to our prior comment 38, we note that you booked 27.5 million barrels equivalent in 2007. Please tell us if you anticipate the de velopment of those reserves within five years of first being classified as proved reserves. 4. We have considered your response to our prior comment 44 and do not concur. Given the importance that you attribute to Sandri dge’s success as an operator, the average cumulative oil and gas production and the av erage age of these wells is material information. 5. We have considered your response to our pr ior comment 47. The abil ity of the wells to pay out their drilling and completion costs will impact the estimate of proved reserves, production and the cash that can be distributed to the Trust’s in vestors. We reiterate our request that you disclose the number of wells th at are not expected to meet their drilling costs. 6. In regard to your response to our prior co mment 55, you state in the last sentence in the first paragraph under Technologies on page 66 that production from other wells confirm that horizontal wells across the AMI have si milar performance with respect to initial production, decline curve shape and estimated ultimate reserve recovery. However, this does not appear to reconcile with the init ial production rates of the horizontal wells drilled to date and the ultimate recovery information that you have provided to us supplementally. Also there appears to be no correlation of performance with lateral length of the horizontal wells. In fact, it appe ars that the best performing well is actually producing from the shortest late ral length of any of the horiz ontal wells. Please remove or revise the last sentence. In this regard, we note that your revised Ri sk Factor language on page 20 actually says “estimated total reserves vary substantially from well to well and are not directly correlated to perforated lateral length or completion technique.” This statement does not support your response. Because of the unpredic tability of the performance and estimated ultimate recoveries, it appears that proved reserve estimates for all the proved

undeveloped wells should be no more than the median estimated ultimate recovery determined for the producing wells. Pl ease revise your document if necessary.
