Integrated Production Modeling & Optimization
Premium Workshop
For PEA Members Only
Production from a field is limited by whichever part of the system is the tightest constraint, and that constraint is rarely where engineers assume it is. It can sit in the reservoir inflow, in the tubing, at the wellhead choke, in the flowline, or at the separator. Treating the well and the surface network as one connected system is the only reliable way to find where production is actually being lost and what will recover it.
This workshop covers integrated production modeling from the sandface to the surface facilities. It begins with well modeling and nodal analysis: building an inflow performance relationship, constructing a vertical lift performance curve, matching the model against measured well test data, and locating the operating point of the well. Participants then work through running sensitivities on tubing size, wellhead pressure, water cut, gas-oil ratio and reservoir pressure, and generating lift curves for use in reservoir simulation.
Inflow modeling is covered for vertical, deviated, horizontal, multilayer and multilateral well geometries, including the assumptions behind each model and where they break down. The workshop then extends from single wells to the full production and injection network, covering pressure losses in flowlines and manifolds, backpressure effects, bottleneck identification and network-wide optimisation.
The final section deals with field development planning applications: testing alternative development strategies, evaluating artificial lift and compression options, running predictions against a defined production target, and generating forecasts. Field case studies are used throughout to show how the methods are applied on real assets and what the results are used for.
The workshop is delivered at an advanced level and is intended for production, reservoir and petroleum engineers involved in well performance and field optimisation.
Workshop Objectives
By the end of this workshop, participants will be able to:
Describe the integrated production system and identify where production constraints occur between the reservoir and the delivery point
Build a well model comprising inflow performance (IPR) and vertical lift performance (VLP) and determine the operating point through nodal analysis
Select and apply appropriate multiphase flow correlations and match the model against measured well test data
Run sensitivity analysis on tubing size, wellhead pressure, water cut, gas-oil ratio and reservoir pressure
Generate lift curves for use in reservoir simulation studies
Apply inflow models appropriate to vertical, deviated, horizontal, multilayer and multilateral well geometries
Model production and injection networks, including pressure losses, commingling effects and backpressure
Identify bottlenecks in the surface network and quantify the production gain from removing them
Evaluate artificial lift and compression options for well and field performance improvement
Test alternative field development strategies and generate production forecasts
Run prediction cases against a fixed production target using coupled well and network models
Apply the workflow to field case studies and interpret the results for development decisions

Excel in Production Engineering
Most production engineering calculations don't need expensive software — they need Excel used well. This live 2-hour beginner workshop shows you how to build the core tools of well performance analysis directly in a spreadsheet. You'll create working models for inflow performance, nodal analysis, and decline curves from scratch, using nothing but Microsoft Excel — so you understand what's happening under the hood instead of treating commercial software as a black box.
