Well Testing—Benefits and Limitations Reservoir Descriptions and Dynamics

Giovanni Da Prat

Description

This course reviews past and current well testing methods. Participants will learn that, although current testing practices may use modern testing equipment and optimized programs and procedures, getting the desired reservoir evaluation in the most economical way often depends on the nature of the formation, fluid properties and the well’s response to the particular testing equipment and field practices. Several field cases are presented to illustrate the benefits of testing and the uncertainties of interpretation.

Topics include:

  • Lessons learned from onshore and offshore case histories
  • Why, how and when well tests are needed
  • Types of tests according to the kind of well completion
  • Acquiring pressure and rate data
  • Monitoring pressure in real time
  • Estimating production rates and pressures
  • An introduction to pressure transient analysis for oil and gas wells.

Instructor

Giovanni Da Prat is an independent consultant based in Buenos Aires. He has more than 28 years of experience in the oil and gas industry, primarily in well test management, pressure transient analysis and production optimization. Da Prat’s experience includes nine years as district reservoir engineer for Flopetrol-Schlumberger in Bogota, where he interpreted well test data acquired from fields in Colombia, Peru, and Ecuador. Before joining Schlumberger, he spent three years with Halliburton Reservoir Services in Caracas as the regional reservoir engineer.

Da Prat has been the author and coauthor of numerous technical articles, and he wrote the book, Well Test Analysis for Fractured Reservoir Evaluation, published by Elsevier in 1990. He was an SPE Distinguished Lecturer in 2003–2004. Da Prat holds an MS in geophysics and a PhD in petroleum engineering, both from Stanford University.
