Cyclic Steam Stimulation (CSS) Engineering Training Course

Cyclic Steam Stimulation (CSS) Engineering Training Course

Introduction

Cyclic Steam Stimulation (CSS), also known as Huff-and-Puff, is a proven thermal enhanced oil recovery (EOR) technique used to improve production from heavy-oil and viscous-oil reservoirs. Cyclic Steam Stimulation (CSS) Engineering Training Course provides a practical understanding of the complete CSS workflow, from reservoir characterization, thermal properties, well selection, steam generation, injection design, soak periods, and production forecasting to performance evaluation and optimization. Participants will explore how steam injection reduces oil viscosity, improves mobility, increases reservoir pressure, and enhances recovery while addressing operational constraints such as heat losses, steam quality, well integrity, water management, and production decline.

The course integrates reservoir engineering, production engineering, thermal recovery, well engineering, process optimization, field surveillance, numerical simulation, and digital oilfield technologies to develop a practical CSS engineering framework. Through real-world case studies, field-development scenarios, engineering calculations, production-data interpretation, and technology-driven optimization, participants will learn how to evaluate CSS projects and make informed decisions that balance oil recovery, steam-oil ratio (SOR), energy efficiency, operating cost, emissions reduction, and asset profitability. Particular attention is given to data-driven decision-making, thermal reservoir simulation, AI-assisted production analytics, sustainability, carbon intensity reduction, and next-generation EOR strategies.
