Course Overview

This course provides comprehensive training on well stimulation techniques aimed at restoring or enhancing production in oil and gas wells. It covers matrix acidizing, hydraulic fracturing, chemical treatments, treatment design, execution, and evaluation of results, giving participants the tools to plan and manage effective well stimulation operations.

Day-by-Day Outline

Day 1 – Fundamentals of Well Stimulation

- Goals and mechanisms of well stimulation
- Types: matrix treatments, fracture stimulation, chemical treatments
- Reservoir considerations: rock properties, damage mechanisms, permeability
- Economic evaluation of stimulation candidates
- Exercise: Identify suitable wells for stimulation based on production data

Day 2 – Matrix Acidizing & Chemical Treatments

- Principles of matrix acidizing in carbonates and sandstones
- Acid types, reaction kinetics, and additives
- Scale and paraffin removal treatments
- Placement techniques: bullheading, coiled tubing
- Workshop: Design a matrix acidizing job for a damaged well

Day 3 – Hydraulic Fracturing Basics

- Overview of hydraulic fracturing principles
- Fracture propagation, height growth, and proppant transport
- Fracturing fluids, proppant selection, and additives
- Frac design parameters: net pressure, fluid efficiency
- Exercise: Perform a basic frac design for a low-permeability reservoir

Day 4 – Execution & Field Operations

- Surface equipment layout and safety considerations
- Pumping schedules and real-time monitoring
- Data acquisition during stimulation jobs
