If you’re producing from unconventional reservoirs, decline curves are a critical component of understanding reservoir quality. They can help you understand where the zones of maximum productivity, and help you predict where you’ll have the best outcome in your next wells. SPE Distinguished Lecturer and Director of USC’s Petroleum Engineering program Iraj Ershaghi will be presenting a one-hour e-symposium, Production Geology, which focuses on using engineering and production data to help with future field development, from geosteering to completion / stimulation. The e-symposium will take place September 10 at 2 pm, Central Time. The course will also include additional materials (articles, review questions) and an opportunity to earn CEU credit and Professional Development Hours.

The goal of this e-symposium is to review an important dimension in the ways geologist can build and update geological models using information from performance data. The foundation of signals imbedded in production/well test data that indirectly relate to the geological characteristics of producing formations will be discussed. Such data can enhance the information available from other geological and geophysical sources and can help in evaluation of residual oil as target for infill drills and added recovery processes.

Specifically, the e-symposium will cover the following:

• Analysis of geological signals imbedded in performance data
• Workflow processes to extract such information
• Importance of history matching to help in revising geological models
• Examples case studies.
