Oil & Gas Production Technology

About the course

Course duration: 2 days

Inorganic scale buildup often leads to premature equipment failure, requiring repair or replacement. It can also prevent production targets from being achieved due to downtime or reduced well productivity, frequently necessitating costly workovers and remedial treatments. As a result, scale formation can significantly undermine both the technical and economic performance of a project.

To effectively manage scale-related risks, operators must implement a robust scale-control management system capable of predicting the likelihood of scale deposition and reliably mitigating its impact across the entire production system. An effective management system begins with a comprehensive risk assessment to identify potential scale locations, their probability, and expected severity over the life of the asset. Case studies illustrating the development and application of such scale management systems will be presented.

Designed for

This course is particularly tailored for petroleum production engineers, laboratory personnel, field operators, system designers, and anyone seeking practical experience in this field, including researchers or managers who want to understand technical issues that support effective decision-making.

Course objectives

  • Develop a comprehensive understanding of scale challenges associated with fluid production, gathering, treatment, and transportation
  • Identify existing and potential threats to uninterrupted fluid flow
  • Develop a proactive Scale-Management System
  • Validate mitigation methods and reassess strategies to enable ongoing optimization and operating cost reduction
  • Design cost-effective, efficient, and reliable mitigation strategies that maintain production targets and extend equipment service life while complying with environmental regulations
  • Define evaluation criteria and calculate Key Performance Indicators (KPIs) related to scaling and produced water treatment
