“Employing Statistically Enhanced Decline Analysis (SEDA) to Attain Accurate
Developed Proved and Possible Deterministic Reserves”
The preferred method of reserves evaluation for producing wells is deterministic. However, when deterministic methods are used, evaluators cannot reliably assign reserves that satisfy the prescribed certainty for each reserves category. In addition, they have no method to quantify the impact that aggregation will have on reserves certainty. This presentation will introduce Statistically Enhanced Decline Analysis (SEDA) - a new method for accurate, consistent reporting of deterministic reserves. To our knowledge, SEDA is the only method available to resolve the deficiencies of deterministic reserves estimates. It also adapts well to existing reserves evaluation software and improves accuracy and consistency at reduced cost.
