05 Fundamentals for Difficult Treatment Applications

Session Chairpersons:

Peggy Lane, BP; John Michael Walsh, CETCO Energy Services; Robert Ryther, Nalco Champion, An Ecolab Company

As produced water has moved from a disposal issue / waste to a resource that is required to enable oil and gas production, the fundamental understanding of the surface and colloid chemistry, microbiology, and fluid mechanics has not kept pace. Most treatment chemicals in use today is based on long-standing and well understood concepts of coagulation, flocculation, zeta potential, in systems that have relatively low levels of polymer, dissolved minerals, and organic contaminants. Today however, very high levels of these materials are involved either deliberately or as a consequence of oil and gas extraction strategies. The traditional microbiological approaches are not adequate either to monitor these systems, or to provide a high degree of assurance for prevention of souring. Mineral precipitation and scale formation is likewise poorly understood in these systems. Papers in this session will discuss these challenges and offer potential solutions. A possible outcome of this session is the formation of a Joint Industry Project to support basic research regarding water treatment fundamentals.

06 Waterflooding - Conventional SWRI, PWRI

Session Chairpersons:

Scott Barrie, H2Oil and Gas; Timothy John Johnson, Tim Johnson & Associates

While there are an enormous amount of water injection systems throughout the world the actual number of systems that achieve their injection targets is much smaller. Even in the case where new technologies and/or appropriate technologies are adopted, they are not always implemented correctly and do not provide the performance and expected uptime. Often this is due to the lack of information and experience on the front end design. This creates future operational problems with equipment and process performance throughout the life of the project. Despite these on-going problems with conventional waterflood operations, the industry is moving to even more demanding applications. For example there are a lot more soft (unconsolidated) sands that require much cleaner water and reservoirs that require low sulfate water to prevent scaling and souring. This session will address the gamut of issues related to sea and produced water injection in conventional waterflood settings.

07 IOR, EOR & Chemical-Based and Low-Salinity Water Flooding

Session Chairpersons:

Peggy Lane, BP; Shiladitya Basu, Hydranautics

Scientific merit, favorable economics, and the need to maintain production levels have contributed to research and implementation of IOR and EOR techniques. These techniques are drawing more on tailored injection water chemistries for incremental recovery, with growing scope in salinity and chemical modification. Additionally, treatment of returned injection and produced waters from these floods is increasingly difficult, with highly uncertain design factors. New technologies and a better understanding of application of traditional technologies is needed, both for the injected and returned produced waters. This session will look at the evolving requirements, applying existing technologies, and recent technology offerings including results.

08 Water Management & Life Cycle - Case Studies

Session Chairpersons:

Drue Ann Whittecar, National Oilwell Varco; Tekla Taylor, Golder Associates

Each aspect of the water life cycle in oil and gas E&P, from sourcing through use, to treatment and management of waste, is inter-related and benefits from integrated planning and communication across an organization. Water management decisions, such as the decision to reuse produced water, should optimally take into consideration metrics such as water treatment technologies, well completion technologies, hydraulic fracturing fluid chemistries, transportation logistics, regulations, environmental and social aspects, site layout and scheduling, and potential impacts to well production. Successful water management strategies account for and optimize the relationships between these aspects in a way that addresses the technical challenges and supports the business objectives of the various stakeholders within the organization. This session will focus on the planning and management of water and its impact on the oil and gas asset. It will explore through case studies, the success factors that lead to improved metrics throughout the life cycle of a project.
