Produced Water Management, Treatment & Reinjection

Introduction

 Produced water is a common fluid stream in exploration and production operations. It consists of formation water or flood water previously injected into the formation. Generally, produced water may be reinjected after being treated. If the injected water contains solids large enough to plug in the formation, injectivity will decline. Downhole solids contributing to plugging may include not only the solids escaping filtration, but also solids generated after water treatment (corrosion, scale, and bacterial products). Consequently, corrosion inhibition, scale inhibition, and bacterial control, as well as filtration, are required for optimizing the rate of water injection.

This Produced Water Management, Treatment & Reinjection training course provides both theoretical and practical knowledge and skills highlighting:

• The latest technologies for treating injection and producing water in both onshore and offshore facilities. 
• Detailed overview of produced water handling mechanisms and methods for its diagnosis, and treatment, in oil & gas drilling facilities.
• Water management, reservoir requirements, and discharge water quality monitoring.
• Microbial, chemical, physical and environmental produced water challenges and techniques used for their mitigation in order to help reduce investments, operation and maintenance costs. 

Objectives

This Produced Water Management, Treatment & Reinjection training course aims to enable participants to achieve the following objectives:

• Understand how to reduce operation and maintenance costs by applying the most efficient produced water treatment techniques.
• Learn about injectivity and scale prevention in reservoirs.
• Gain an understanding of water management in oil & gas production facilities.
• Understand how to improve produced water and injection water quality.
• Learn about the most efficient sampling and oil in water monitoring techniques.
• Gain updates on the latest environmental legislation and regulations.
• Learn how to efficiently remove sulphate and bacteria from injection water.
• Gain tips on how to cope with complex oilfield microbial challenges.
• Understand how to maintain sour gas and hydrogen sulfide production under control and mitigate the risk of corrosion.
• Learn about emulsion formation, mitigation and prevention techniques.
• Gain knowledge on produced water treatment for mature fields and subsea satellites.

Training Methodology

This Produced Water Management, Treatment & Reinjection training course will be delivered by extensively interactive training methods, encouraging attendants to share their questions and experiences and apply the course material to real-life work case studies. The attendants will also be encouraged to raise more of their questions and to share developing the right answers using their analysis and experience. Course material through PowerPoint equipped with necessary animation, learning videos, and general discussion to provide participants with a full understanding concerning the subject course will be provided.

Who Should Attend?

Plant and production engineers, chemists, and senior operations personnel are responsible for designing, operating, and maintaining facilities that process and manage produced water.
