The venue is the Glenbow Museum’s theatre which is located on the main floor. Lunch is from 11:30 to noon.

As the oil industry is shifting fast into the exploitation of tight and unconventional reservoirs; with very low permeability, reserves estimate becomes a challenging task. Reserve definitions; such as, Stimulated Reservoir Volume (SRV) and Contacted Reservoir Volume (CRV) will be discussed. When all methods fail, we tend to seek help from the decline analysis technique. Decline curve analysis and its derivative; such as the Power Law Exponential (PLE) and RTA methods, are also explained. More advance methods using numerical techniques can produce more reliable reserve estimates and can deal with complex reservoirs and heterogeneities. Several case studies will be presented to demonstrate the various techniques.
