Description

ABSTRACT ADVANCED DECLINE CURVE ANALYSIS COURSE This one-day course will show how log-log type curve analysis can be performed on declining production rate data completely analogous to the log-log type curve matching procedure presently being employed with constant rate case pressure transient data. Numerous case studies of individual oil and gas wells, of groups of wells in a field and of total fields will be presented. Some of the basic concepts of decline curve analysis will be brought out with each of the examples. Course objectives are: 1. To highlight the importance of identifying transient production when present. Never use the depletion equations for rate time analysis for transient production. 2. To define the variables in the Arps’ Decline Equation: b, Di and Qi, in terms of simple reservoir engineering concepts and reservoir drive or recovery mechanisms. A physical reservoir engineering basis for each of the variables will be pointed out during the lecture. 3. To present guidelines as to what the decline exponent, b, should be for various types of gas and oil reservoirs. Layered/no-crossflow reservoir performance is the primary explanation for b values between 0.5 and 1.0. 4. To show when and how rate time data should be normalized using flowing pressures or number of wells. 5. To show when and how rate time data should be re-initialized for log-log type curve analysis, smoothing data and how to treat changes in skin due to stimulation or re-stimulation.
