Performance Analysis, Prediction, and Optimization Using Nodal Analysis - PO2
Discipline: Production and Completions Engineering
Duration: 5 days
Instructor(s): Mason Gomez, Manickavasakan Nadar, Scott Wilson
Nodal analysis views the total producing system as a group of components potentially encompassing reservoir rock/irregularities, completions (gravel pack, open/closed perforations, open hole), vertical flow strings, restrictions, multi-lateral branches, horizontal/hilly terrain flow lines/risers, integrated gathering networks, compressors, pump stations, metering locations, and market/system rate/pressure constraints. An improper design of any one component, or a mismatch of components, adversely affects the performance of the entire system. The chief function of a system-wide analysis is to increase well rates. It identifies bottlenecks and serves as a framework for the design of efficient field wide flow systems, including wells, artificial lift, gathering lines and manifolds. Together with reservoir simulation and analytical tools, Nodal analysis is used in planning new field development. Initially, this technology was applied using pressure traverse curves and simple PI models. Now state-of-the-art software programs have enabled a well-trained engineer to concentrate on matching field data, interpreting results, and understanding a system's interdependencies. Software is used extensively during the class and the participant is encouraged to bring his/her own laptop and nodal software. However, if the attendee chooses not to supply his/her own software, nodal analysis, and gas deliverability planning programs can be provided. One personal computer is provided, at additional cost, for each two participants.
Alternatively, NODAL Analysis Workshop available via PetroAcademy.
"The real world examples helped us (having to identify errors on reports). Also using SNAP to solve the problems and get experience using computer models." - Drilling Engineer 1
"The instructor made the class interesting, applicable, and enjoyable. He knows his stuff!" - Petroleum Engineer
