Description
This two-day workshop entails a fundamental understanding of well performance using several tools, such as RTA and DCA. Application of DCA emphasizes matching the cumulative-production curve for retaining solution consistency and objectivity. Overall, the suitability of these tools for reserves forecasting will be the cornerstone of this workshop. Although deterministic reserves estimation is the main emphasis, the probabilistic approach will also get addressed.
In DCA, we introduce methods other than Arps to gain a broader understanding of the pros and cons of different approaches. In this overall context, we emphasize using the cumulative production curve for minimizing the inherent noise in any rate profile. Equally important, we show that collapsing of well shut-in periods is a must in any DCA. Finally, the goodness of the Arps method since its inception in 1945 does have a theoretical justification.
Learning Outcomes
Understand data collapsing during the well shut-in periods for preserving mass in the drainage volume
Gain insights into the physical meaning of the Arp’s b-factor over time to assess various degrees of pressure support over time
Use rate-transient analysis (RTA), when possible, to gain insights into long-term performance
Understand reserves classification in Petroleum Resources Management System (PRMS)
Solution workflows for participants’ specific problems
