Preliminary Technical Agenda
Tuesday, November 17
Session 1: Reservoir Modeling
Session Managers: Mars Khasanov, Rosneft, and Timur Manapov, TNK-BP
Description of the waterflooding process by geological and mathematical modeling is an important task for forecasting reservoir behavior during displacement of oil by water. Modeling allows for selection of the optimum waterflooding system (location of injection wells, operation modes, injection control methods), ensuring the most efficient development of reservoir and enhanced oil recovery. Participants will share experiences of modeling waterflooding optimization. The main issues of the session are
- Completeness and quality of input information for development and updating of models
- Problems of adaptation of models to development background
- Modeling of waterflooding for complicated reservoirs
- Role and place of different classes of models in waterflooding management
- Generalization of results of analyses of processes and waterflooding systems using models (common regularities and dependences on formation types)
- New and emerging waterflooding modeling technologies
Session 2: Reservoir Surveillance
Session Managers: Jean-Mark Genkin, Shell
Reservoir data acquisition is key to the optimisation process. From one side, water production and injection represent costs that operators want to minimize whilst maximizing oil production and reserves. From another side, timely understanding of remaining oil provides opportunities to better target additional activities to move more oil into producer wells. This session will focus on case studies of successful surveilance/monitoring programs that have increased oil production and minimized water production. The goal is to share experience in techniques and methods of understanding areal and vertical (between reservoir layers) distribution of production and injection.
Session 3: Waterflood Engineering
Session Managers: Alexander Shandrygin, Schlumberger, and Stanislav Zhdanov,
VNIINEFT
Engineering aspects of waterflooding management are very important to improving hydrocarbon field development effectiveness. The technological decisions for waterflooding a reservoir made during field development plan preparation and following field development, dramatically influence current and cumulative hydrocarbons production and recovery coefficient.
Waterflooding management is not a simple task, because of the very complex processes taking place in formations during displacement by injected water in case of artificial waterflooding or formation water in case of a natural water-drive regime. For that, reservoir engineers have numerous, but rather limited methods of waterflood management. In this session, some of the main technologies that will be considered are
- Waterflooding system and well pattern optimization
- Waterflooding management by adjustment of well operation parameters
- Can horizontal and multilateral producers and injectors be considered as technologies for the increase of waterflooding effectiveness?
- Methods of sweep efficiency improvement without chemical agent injection

Session 4: Problem Identification
Session Managers: Philippe Enkababian, Schlumberger, and Oleg Pichugin, Concord
Water shut off can be accomplished using a variety of different chemical solutions
and mechanical devices. Choosing the specific technique primarily based on accurate
diagnostic and well specific technical considerations is key to the success of
conformance control. The discussions in this session focus attention on
- Mechanism of excessive water production (problem types).
- Source of excessive water inflow (evidence, correlation, and verification).
- Available and newly developed diagnostic methods and tools
Sessions 5 AND 6: Injectors and Producers
Session Managers: Igor Kuvshinov,
Halliburton, and Gregory Malishev,
SurgutNIPINeft Tuymen
Wells are major sources of knowledge on reservoir properties and saturating fluids. Being a product of the field development model, wells are different in purpose and design. Well pattern in turn influences water injection patterns and methods of reaching fluid flow conformance in reservoir. Formation and near bottom-hole zone stimulation techniques evolve as flooding fluid front propagates. Although water injection and reservoir fluid recovery have similar in purposes, they still have a number of differences. Differences are stipulated by the displacement mechanism as well as the targets to achieve by various techniques of well intervention.
A wide range of typical discussion topics will be covered.
- Water control while stimulating
- Using formation isolation methods for reservoirs with complex geological structure, in particular, the active bottom/marginal water, undersaturated deposits, hydrophilic/hydrophobic reservoir, etc.
- Prediction of well productivity after performing operations to control the fluid influx
- Planning and practice of well bottom-hole construction reckoning for the control of water influx at later stages of wells operation
- Integrated work for changing the fluid injection and recovery conditions in separate areas of the field

Case Studies and Economical Aspects
Session managers: Jean-Mark Genkin, Shell; Timur Manapov, TNK-BP; and Don Wolcott, Raptor Oil & Gas Co.
Everywhere in the world, mature waterflood operations require high a degree of operational excellence. In a Russian environment, additional challenges to field developments are added by a combination of low profit margins (due to high transportation costs and fiscal regime) and high degree of regulatory control. The latter may reduce the operator flexibility in optimizing his/her cost base. This session will cover real case studies of mature oil fields that have succeeded in maintaining their economic viability at high water-cut through innovative waterflood management. Focus will be on capturing the lessons learned for new developments, especially if the flood could be started over.
