“AUTO-DCA, Faster DCA, and Intuitive Analysis,” at the TIBCO Energy Forum in Houston
Presentation Abstract: Fitting production history with traditional Arps’ equation or any other decline curve analysis (DCA) method is a well known approach. The result of DCA combined with completion and geological data can reveal many insights. However, this is monotonous and time-consuming when repeated for more than 100 wells. Typically, a manual workflow starts by collecting daily/ monthly production data, selecting the DCA method and changing b and d factors to fit the history data. This process results in significant burden on an engineer’s time - taking about 10 min per well and 1 week for 100 wells. Using AUTO-DCA TIBCO Spotfire enhanced visualizations and TIBCO Enterprise Runtime for R (TERR), an entire DCA analysis can be generated in minutes for 100 wells. This provides unprecedented evaluation of production and reservoir performance for the field, connecting dots and correlating cross functional information to optimize well and fracture spacing.
