Well Inflow/ Outflow NODAL™ Analysis is an integral part of a production or completion engineer’s work scope, and is often applied throughout a well’s life to maximize value - from the beginning of the completion design process through underperforming well diagnostics. This workshop provides a comprehensive overview of this analysis technique, emphasizing real world application through multiple problems from different perspectives.


Upon completion, participants will be able to approach a problem recognizing potential solution methods, prepare data for the analysis, identify sources of error, perform an analysis with industry software, and present a holistic recommendation. Topics related to perforating, components of skin, matching transient test data, outflow limitations, selecting artificial lift, liquid loading, and incorporating fluid PVT properties will be covered.

Operating Company and Service Company engineers and technical managers responsible for performing or reviewing well systems analysis from at least one perspective (perforating design, tubing sizing, post stimulation evaluation, etc.). Participants should be in a role that requires that they regularly perform or are required to technically review well inflow/outflow analysis.

  • Recognize the application and limitations of traditional well systems analysis
  • Identify data requirements for a meaningful analysis
  • Accurately model the various components of skin, including perforating
  • Assess outflow performance, including liquid loading, tubing constraints, and artificial lift
  • Confidently approach well systems analysis from multiple perspectives and select the correct diagnostic strategy for your well conditions

*SNAP is a petroleum engineering software tool designed to conduct well performance predictions using nodal analysis. With SNAP, participants can analyze relationships between the reservoir, wellbore, and surface equipment to determine a well's production capacity. SNAP has built in modules for the design and troubleshooting of gas-lift or jet pump installations.
