The goal of this interactive session is to expand the learning and networking experience. Small groups, led by a facilitator, will have the opportunity to openly discuss and collaborate on:

• Produced Water Treatment Technologies & Future Outlook
• Regulatory & Environmental Performance
• Chemistry & Fouling Management
• Subsurface-Surface Integration for Water Management
• Monitoring, Automation & Digital Optimization

This session shares best practices and produced water management trends as well as overall integrated water management strategies, from treatment to the full lifecycle of water.  With increasing produced water rates, the role of produced water and the opportunities in today’s energy expansion market will be discussed.

• Proactive Management of Iron Sulfide – a Microbiological Perspective in Matured PW systems
   Ken Wunch, Lanxess Materials Protection Products

An optimum water management scenario reduces the produced water from hydrocarbon bearing zones, so that the handling, treatment, re-injection, or disposal costs are minimized. In this session will highlight state-of the art wellbore integrity, fluid saturation diagnostics, flow profiling, and conformance technologies that aim at achieving this goal at the wellbore level, where the water influx starts. 

Session Chairpersons: Rogerio Carvalho, Petrobras; Luis Quintero, Oilfield Development Specialists

Speakers:

• Instantaneous Densification of Cement to Prevent Water Flow Behind Casing
   Luis Quintero, Oilfield Development Specialists; Jim Rairigh, WT Bell Int'l 
• Rock-on-a-Chip and Produced Water Reinjection: Microfluidic Techniques for Evaluating Injectivity Loss
   Jan Clinckspoor, CNPEM
• Impact of Water Control in Enhanced Oil Recovery Wells
   Chip Westaby, Benchmark Measurement Solution

Water quality constitutes a critical determinant in advanced reservoir management, directly influencing the efficacy of oil recovery. The process of water injection not only maintains reservoir pressure but also facilitates the mobilization of hydrocarbons by providing the necessary drive energy. Key operational parameters—including injectivity index, susceptibility to reservoir souring (notably via sulfate-reducing bacteria activity), composition of produced water and reservoir reactivity—are fundamental to preserving reservoir integrity and optimizing both sweep efficiency and ultimate recovery factor. This session will examine the interactions occurring within the reservoir matrix, discuss water quality specifications required for sustained operations, and present best practices for the integrated management of water systems in field-scale applications.

This session will address mature-field challenges driven by rising produced water rates and EOR methods such as polymer flooding or another that alters the characteristics of the produced water. We will discuss how  high production water rates or changes in water composition can impact surface operations—particularly separation, treatment, water reuse/injection, and discharge compliance. The goal is to share practical learnings and integrated approaches that maintain operational efficiency while meeting environmental and regulatory requirements.

Flow Assurance applies economical and technically sound processes to ensure reliable delivery of reservoir fluids from the pore space to production facilities. This session examines water management challenges through a flow assurance lens, including inorganic scale control, souring mitigation, solids handling, corrosion management, and water quality assurance.

The discussion will cover Flow Assurance–driven well interventions, such as chemical water shutoff, scale inhibitor squeezes, chelant, and acid treatments for scale remediation and well reactivation, and tracer diagnostics to evaluate system performance and treatment effectiveness.
