01 Deepwater / Offshore 1

Session Chairpersons:

Bob Long, U.S. Water Energy Services; Frank Richerand, Enviro Tech Systems

For deepwater offshore water treatment, there is a continuing need for more intensive and compact technologies. In this session, recent technology offerings, pilot tests and full scale implementation results will be presented. Another related and continuing challenge for offshore is how to handle the inevitable increase in water cut that occurs later in life. One option is subsea processing. This session will also include a look at subsea produced water handling, and subsea injection / disposal. A trend that is gaining momentum in the industry is the use of tertiary water treatment. In some cases, tertiary treatment is being implemented ahead of regulatory requirements, in the interest of environmental protection. Options available, their costs, benefits, and performance will be presented. There is continued need to improve the application of conventional technology. The industry still struggles with issues of operability, maintainability, and reliability and the need for better understanding of fit for service design. The role of online monitoring and latest technologies will be presented. Due to the wide ranging scope of topics and technologies in this session, the papers will be presented by the topmost industry experts and will provide a comprehensive overview of each subject.

02 Onshore - Conventional

Session Chairpersons:

Sunil Ashtekar, Shell; Ted C. Frankiewicz, Spec Services

The subject of produced water treatment onshore has been around for decades. However, in the past several years or so, a number of technically complex challenges have made this subject anything but conventional. This session will focus on recycling when water injection is not an option; meeting agricultural / irrigation standards in a cost-effective way; avoiding reservoir contamination; monitoring and control; dealing with organics in flow back / produced water evaporation or zero liquid discharge; differences between offshore and onshore; salt recovery and the potential need for recommended practices related to disposal options. A major challenge for some regions of the world is the question of how to manage produced water volumes when there is a lack of injection availability; recycling for oil and gas application or recycling for irrigation are two options. Zero liquid discharge is another option. Purification and marketing of the brine can help mitigate costs but there are several technical problems. In Zero Liquid Discharge, one concern is how the dissolved and dispersed organics affect the design of a chemical precipitation system for producing brine feed and the quality of NaCl salt on crystallization of such brine feed. The problem is more exacerbated in unconventional but indeed exist for steam generation as well.

03 Onshore - Unconventional

Session Chairpersons:

Paul Verbeek, FMC Technologies; John Michael Walsh, CETCO Energy Services

Development of unconventional fields generally requires competent planning and management with respect to water. Now that the industry has had a few years of experience, a better understanding of the requirements and technical solutions is beginning to emerge. For most hydraulic fracturing flow back treatment, organic and mineral suspended solids must be removed. Given the high concentrations of these solids, some technologies are more suited than others. Also, the chemical treatment to prevent scaling and biofouling must be competently applied in the field. This session will discuss various issues involved in water for unconventional fields including: planning and management strategies for water in shale oil and gas; coal bed methane (coal seam gas) water treatment and disposal options; technical options for recycling hydraulic fracturing flow back and technologies for water treatment in steam flooding.

04 Subsurface Water - Reservoir & Wells

Session Chairpersons:

Kris M. Bansal, ConocoPhilips; Paul John Evans, Chevron ETC

Subsurface water can have a good or bad impact on field economics. Maximizing the good and minimizing the bad impacts will largely determine field life through ultimate recovery, reserves acceleration/deferment, the requirement for sustaining capex (e.g. increased well numbers and recompletions) and opex. A critical success factor is that subsurface water is managed with adequate levels of cooperation and communication between surface and subsurface disciplines. This session will address areas of knowledge and technology that may cut across the touch points from reservoir, through wells to surface and include how to prevent or reduce unwanted produced water volumes; monitor injection and produced water volumes; determine and achieve the levels of treatment required for produced water injection / reinjection and how to optimize the benefit of waterflood.
