Agenda

Planning development strategies for oil reservoirs is a very important stage in maximising oil recovery and reservoir management over the life cycle of any field development. One of the effective reservoir management strategies is the process of injecting water into the aquifer/oil column to maintain the reservoir energy/sweep and enhance the oil recovery. Voidage replacement ratio (VRR) was studied to obtain the best WI planning strategy to maximise oil production recovery and therefrom profitability. For all WI projects planning and designing constitutes an important element for maximise oil production recovery and therefrom profitability.

In order for the WI Design to be effective and efficient, appropriate sizing of the WI facilities and capacity, timely decision-making and placement of facilities are essential. Unfitting design may result in a big loss due to irreversible effects that occur in the reservoirs.

The objective of this session is to focus on the fundamental inputs required to assure the successful and timely implementation of a technically suitable WI project. The lessons learnt need to be captured and new approaches must be adopted to avoid repetitive mistakes.

Modularisation and standardisation options should be considered to derive the best value from WI. Deciding on the best injection strategy involves not only analysing the surface of WI capabilities but also subsurface aspects, such as geology rock properties and geomechanics. WI design should strike a balance between cost and operational effectiveness to meet water quality and reservoir management plan.

This session will cover topics related to improving methods, innovations of planning, and designing WI programmes based on lessons learnt and field applications.

Discussion Leaders:

• Sangomar Field Waterflood Design, Mohammad Zafari, Woodside Energy; Zachary Brown, Woodside Energy
• Predicting Impact of Reservoir Souring Associated with Water Injection and Low Reservoir Temperature in Deepwater AB Greenfield with Mitigation Plans, Irzie Hani Abdul Salam, PETRONAS
   

Advancements in well architecture and completion design techniques continue to provide significant value to unlock new / complex reservoir targets and optimise field development and ultimately improve recovery factors.

Implementation of horizontal, multizone, and multilateral well architectures and advanced well completion techniques is growing globally and recognised as value adding well construction and completion methods to optimise WI performance and improve field recovery.

This session shall provide discussion platform on key well type and completion that provide prudent reservoir management opportunities while optimising the WI operations in oil fields.

Discussion Leaders:

• Production Micro Solutions:  Focusing on Last Mile Automation for Production Operations, Garud Sridhar, Schlumberger

Waterflooding is a demonstrated relatively low-cost approach to maintaining production and increasing oil recovery. In order to realise the full benefit of any waterflooding project, it is important not only to understand and implement time-tested concepts and practices but also to measure efficacy through utilisation of various surveillance techniques throughout asset life- from source water quality to produced water analysis, and everything in between as water circulates through facilities, wells and reservoirs.

The integrated role of geoscientists, petroleum engineers, field engineers, chemists and operators is critical in meeting project expectations.

This session will focus on how different operators and service providers utilise new and existing surface and subsurface surveillance technologies to gain insights into flood performance and make use of this information to optimise production and recovery.

• Evaluating Acid Stimulation using Pressure Transient Analysis in Multi-zonal Water-Injectors for Improved Injectivity and Sweep Efficiency, Charlene Bong, Brunei Shell Petroleum
• Waterflood Sweep and Reservoir Management Insights from Early 4D Seismic Acquisition, Hayley Pedler, Woodside Energy; Maddison Fairburn, Woodside Energy
• Integrating Surface and Subsurface Surveillance Data in Waterflood Fields for Maximising Hydrocarbon Recovery, Arfan Ali, Brunei Shell Petroleum

The infrastructure to improve oil production and recovery via waterflood by having a WI Facility on an existing platform or even greenfield are CAPEX Intensive.  It is highly dependent on the design capacity, WI schemes, treatment procedures and planning, whereas the Operations Excellence and Lifecyle Management could extensively increase the Unit Production Costs (OPEX) of an operating asset. Therefore, it is very critical to manage lifecycle risks of any secondary or tertiary recovery investments compared to natural depletion before embarking on the full project development. 

This session will focus on how different operators and service providers manage early risks of investment, ageing facilities challenges in water treatment, water chemistry and flow assurance as well as by product and waste management in ensuring a holistic and robust WI management to increase the production and recovery of a field.

The Oil & Gas industry has played a pivotal role in the economic transformation of the world, fuelling the need for heat, light and mobility of the world’s population. Today the Oil & Gas industry has the opportunity to redefine its boundaries through digitalisation. After a period of falling crude prices and, frequent budget and schedule overruns, greater demands of climate change accountability and difficulties in attracting talent, the Oil & Gas industry can provide practical solutions. Digitalisation can act as an enabler to tackle these challenges and provide value to all its stakeholders.

While digitalisation could be a source of positive change, there are a number of challenges that need to be overcome to realise its full potential. The increase in digitalisation aspects have created new risks around data privacy, security and other business challenges related to changing expectations, cultural transformation, outdated regulation and most importantly, skill shortages and capability development.

• Digitalisation effort in Pattern Review – A Step Towards Effective Waterflood Management, Hamizan Kamaludin, Brunei Shell Petroleum; Sia Kok Hau, Brunei Shell Petroleum
• Integrated Analytical Workflows for EOR Surveillance, Management and Optimisation, Sulaiman Sidek, PETRONAS Carigali Sdn Bhd; Vo Tri Nghia, Schlumberger
