Advanced Acidizing: Design, Laboratory Testing, Simulation & Field Applications
Premium Workshop
For PEA Members Only
Acidizing is one of the most widely used stimulation methods and one of the most frequently mis-designed. Success depends on matching the acid system to the rock and the fluids, getting the diversion right, and executing the treatment the way it was engineered. This workshop covers the full acidizing workflow across sandstone, carbonate and geothermal reservoirs — treatment types and reaction principles, wormhole development in carbonates, diversion techniques, acid additives, laboratory testing and fluid-rock compatibility, the engineering calculations needed to size a treatment, surface stimulation equipment for onshore and offshore work, simulation-based optimisation, and post-treatment job evaluation. Throughout the two days the emphasis stays on field practice: what works, what fails, and what the results tell you afterwards.
Workshop Objectives
By the end of this workshop, participants will be able to:
Distinguish between matrix acidizing, acid fracturing and acid washing, and select the right treatment type for the well
Apply sandstone acidizing principles including HF/HCl systems, reaction sequence and precipitation control
Explain carbonate acidizing reaction kinetics and how wormhole structures develop and propagate
Adapt acidizing design to geothermal well conditions and high-temperature constraints
Select and apply diversion techniques and evaluate their effectiveness across the treated interval
Identify the formation damage mechanisms caused by acidizing and design treatments that avoid them
Specify acid additives — corrosion inhibitors, iron control agents, surfactants, clay stabilisers — and justify each selection
Plan and interpret laboratory tests on acids, additives and fluid-rock compatibility
Perform acid volume, concentration, rate and pressure calculations for a complete treatment design
Use simulation to optimise treatment design and predict acid placement and penetration
Select appropriate stimulation equipment for onshore and offshore operations
Evaluate acidizing job performance from post-treatment data and identify what went wrong when results underperform
Build a complete acidizing design from real well data

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.
