The oil and gas industry spends billions annually dealing with unwanted water production. This includes costs for separating, treating, and disposing of produced water, as well as potential impacts on well performance and lifespan. Water production poses significant challenges in oil and gas operations, leading to reduced hydrocarbon recovery, increased operational costs, and environmental concerns. Effective Water Zone Shutoff (WZO) strategies are essential for managing water inflow, improving reservoir performance, and extending well lifespan. This in-depth workshop will explore the latest techniques and technologies for identifying, diagnosing, and implementing water shutoff solutions in conventional and unconventional reservoirs. Attendees will gain insights into mechanical, chemical, and reservoir engineering approaches for controlling unwanted water production while maintaining hydrocarbon flow.

Key topics covered include:

• Identifying and diagnosing water breakthrough using logging, tracer, and production data analysis
• Mechanical shutoff techniques, including packers, cement plugs, and gel treatments
• Chemical water shutoff solutions, such as polymer gels, relative permeability modifiers (RPMs), and crosslinked systems
• Reservoir-based strategies for optimizing well placement and completion design
• Case studies and field applications showcasing successful water shutoff interventions
• Regulatory and economic considerations for implementing water shutoff programs
