This two-day course is an introduction to inorganic scaling. It includes an overview of the different types of inorganic oilfield scales encountered during production, and the various methods used to control them. Field examples will illustrate the importance of an effective scale management strategy.
- Why scale forms and how to treat it, including both chemical and engineering solutions
- Conventional acid soluble scales (carbonates) and non-acid soluble scales (sulfates) as well as other less common scales such as sulfides
- The chemistry of scale inhibition as well as the benefits and limitations of different chemical inhibitors
- The squeeze process, the mechanisms involved, and the various chemical and reservoir factors that control the treatment lifetime, as well other chemical deployment methods such as continuous injection, etc.
- Scale removal, including both mechanical and chemical methods
- The influence of initial field design and varying production conditions on the control of inorganic scales
- The use of modeling tools such as scale prediction software, reservoir simulators and near well-bore treatment models
- A technical, economic, and risk-based analysis process for estimating total field scale management costs for new field developments
- Throughout the course, extensive reference is made to real field case studies and other published works to illustrate the importance of the various aspects covered.

This comprehensive course covers the full spectrum of well treatment and stimulation options for carbonate and sandstone reservoirs. It begins with a review of the various mechanisms that can damage a formation and ways to avoid them. Next, the discussion turns to acid systems for carbonate and sandstone formations, treatment design the selection of additives, and the use of coiled tubing in extended reach and multilateral wells. The week will end with an introduction to new technologies for carbonate acidizing. Case histories illustrate some of the treatment options.
- What causes formation damage in carbonate reservoirs?
- Acids and additives used in carbonate and sandstone formations
- Candidate selection, job design, and execution
- New technologies

This course presents a holistic approach to flow assurance. The course will introduce technologies, workflows and their deployment for the identification, characterization, and management of flow impediments, such as slugging and precipitation of organic and inorganic solids. The course will present best practices and fit-for-purpose design solutions for minimizing the risk of flow stoppage while transporting hydrocarbons from “Pore to Sales Meter”. The principles will be demonstrated using field examples from around the world.
- Introduce key impediments to flow, including slugging and precipitation of organic and inorganic solids, with examples from various challenging environments
- Review technologies for capturing fluid samples and characterizing their PVT properties
- Define current measurement and modeling approaches for characterizing production-chemistry impediments, such as asphaltenes, paraffin waxes, hydrates and inorganic scales
- Introduce fluid flow and heat transfer concepts and their relationship in precipitation of organic and inorganic solids
- Demonstrate the value of a systematic and holistic flow assurance program for production systems and operations, using case studies from various field locations around the globe
