Session 1: Regulation on Produced Water Treatment and Environmental Impact
Session Chairpersons Rohaizad Mohd Norpiah, PETRONAS; Azlina Khairi, PETRONAS; Zunita Mahar Afandi, PETRONAS

The potential harm caused by the ocean disposal of produced water to the ecology has become a major concern. Produced water is a complex mixture of dissolved and particulate organic and inorganic chemicals. The concern of the chemicals in produced water is due to their concentrations, that may be high enough to cause bioaccumulation and their toxicity. Marine organism / animals near a produced water discharge may bioaccumulate metals, phenols, and hydrocarbons from the ambient water, their food, or bottom sediments.

Hence, the principal purpose of produced water related regulations is to protect the environment. While some produced water management activities are subject to regulatory standards, others are subject to operational standards set by operators or end users. In this session, we will discuss the various regulatory requirements / standards on produced water management, including discharges, that relate to the environmental impacts posed by produced water.

Discussion Leaders:

  • A Risk-Based Approach to the Environmental Management of Produced Water Discharges, Mathijs Smit, Shell International
  • Challenges in Produced Water Management in Upstream Operations in View of Compliance with Countries’ Legal Requirements, Nurul Ilmi Mohd Yunus, PETRONAS

Session 2: Application of Produced Water Re-Injection
Session Chairpersons Siti Rohaida Mohd Shafian, PETRONAS Research Sdn Bhd; Raj Kumar Masilamoney, Petrotechnical Inspection (M) Sdn Bhd

Produced water reinjection (PWRI) has been used for pressure maintenance during waterflood operations. It also been used as underground storage in order to minimize the impact of produced water handling at the surface.

Poor water quality with the presence of residual hydrocarbons, inorganic materials, dissolved solids, chemicals, particulates and minerals from formation can lead to loss of injectivity and formation damage during reinjection process.

Improved PWRI process integrate the conventional and advanced water treatment process such as treatment techniques, separation, filtration and coalescence technology to increase the water injection performance.

Discussion Leaders:

  • Novel Approach for Realising Low Cost Produced Water Reinjection for Offshore Application, Muhammad Zakwan Mohd Sahak, PETRONAS

  • Injectivity Impairment and Well & Water Management during PWRI

    Pavel Bedrikovetsky, Australian School of Petroleum, University of Adelaide

Session 3: Field Development Plan with Produced Water Management in Mind
Session Chairpersons Sriyanta Hadi, PETRONAS; Mior Zaiga Sariman, PETRONAS

Produced water is an inextricable part of any oil/gas production. Produced water forecast in Field Development Plan (FDP) exercises is crucial. The actual produced water volume that is away from FDP requires strategy restoration. Enforcement of more stringent environmental regulations can create an additional factor where this deviation can adversely affect the project economics.

Low oil price scenario is a challenging situation, and a detail strategy must be envisaged in FDP to address all challenges throughout the whole field life. The production forecast that includes produced water and associated contaminants is important in produced water system design and strategy. Generic unspecific content for the produced water management in the FDP is a thing of the past. A well-planned and strategic development concept in produced water management at the early stages of FDP is crucial. 

Discussion Leaders:

  • Water Management System: Best Practices for Onshore and Offshore Development, Fairoz Irfan Daud, PETRONAS
  • Produced Water Reuse through Membrane Technology, Ronald Van't Oever, Pentair X-Flow
  • Offshore Produced Water Treatment Systems: Challenges, Lessons Learnt and Future Development Strategies, Zalina Ali, PETRONAS

Session 4: Produced Water Treatment from Aging Assets and Mature Fields
Session Chairpersons Syarifah Noorlia Wan Bujang, PETRONAS; Ana Hasrinatullina M Basri, PETRONAS Carigali Sdn. Bhd.; Hooi Ling Lee, Mubadala Petroleum

Produced water is the largest waste stream in the oil and gas industry and its volume varies as fields mature along with its aging assets. The characteristics of produced water is dependent rock formations e.g. in Middle East and Upper Midwest of America, produced water is up to 10 times more saline than sea water while produced water in Malaysia is less saline compared to sea water.

Produced water is also a carrier for organic compounds, produced sand, sludge, naturally occurring radioactive materials (NORM) and production chemicals. Produced water characteristics and quantity also varies significantly over the lifetime of a field, and these changes are complex and site specific. This leads to a need to have customized strategies with periodic review for each field to prevent and mitigate issues related to produced water management and optimize operation and maintenance cost. This combination, along with increasingly stringent environmental regulations creates a challenge to operate safely and sustainably. Determining an optimal produced water management strategy requires a holistic techno-economic approach e.g. treating and disposing water at an abandoned well can minimize expenditure required for well abandonment. 

Discussion Leaders:

  • Produced Water Reuse towards Circular Economy- Case Study, Syed A. Ahmed, Saudi Aramco  
  • Using Wastewater Injection for Carbon Storage, Chawarwan Khan, Stratum Reservoir

  • High yield improvement of produced water quality without additional treatment, Kon Kee Jun, Mokveld Valves B.V.

Session 5: Managing Challenging Applications in High Contaminant Fields Operation
Session Chairpersons Muhammad Muhsin Ahmad Fuad, PETRONAS; Idzham Fauzi M Ariff, PETRONAS Elizabeth James, SEA Hibiscus Sdn. Bhd.

Presence of contaminants in reservoir production fluid including solids, acid gases, injected chemicals and organic acids can lead to produced water treatment inefficiencies and can adversely impact facilities integrity. In deepwater operations, produced water breakthrough often worsens the existing flow assurance issues for the field e.g. hydrates formation and slugging operation due to bulk increase in water/liquid presence in the system. Managing these issues including liquid handling and assuring discharge compliance may require extensive resources, strategic long-term planning, prudent asset maintenance program and enhanced technology solutions. This session shall outline the operational experience in these challenging applications and what effective produced water management strategies are available to mitigate their impact.

Discussion Leaders:

  • Journey in Managing the Effluent Discharge Quality through Chemical Application in a High Contaminants Gas field, Subramanian Gnanadesigan, PETRONAS Carigali Sdn Bhd
  • Threat of Contaminants to the Produced Water of Aging Contaminated Oil Field, Wan Mahsuri Wan Hashim, PETRONAS
14:30 - 15:00
15:00 - 16:30
Session 6: Emerging Technologies – Solutions and Digitalisation
Session Chairpersons Khor Siak Foo, PTTEP; Ming Yang, TÜV SÜD National Engineering Laboratory

Digital tools are increasingly used for oil and gas production to improve operations efficiency and to reduce costs. Real time measurement technology plays an important part in these tools. For produced water management and handling, produced water quality must be measured in terms of its oil and / or solids content regardless if the produced water is to be discharged, re-injected or re-used. Online oil-in-water measurement technology has been available for the oil and gas industry for many years. It has been predominantly used for process trending and optimisation to date. However, it is now increasingly considered for oil-in-produced water discharge reporting and for produced water treatment automation in particular for remote unmanned installations. In this session, we shall discuss the latest in using online oil-in-water measurement technologies for produced water treatment, management and their roles in a production digitalisation era.

Discussion Leaders:

 

  • Widening Operators Capabilities Thanks to Online Monitoring of Produced Water Quality, Martin Datler, OMV 
  • The Use of Machine Learning and AI for Produce Water Sensing Applications, Connor Douglas, Advanced Sensors 
  • Inhibitor Selection Utilising Digital Application and Analytics for Produced Water Management, Jonathan Collins, Baker Hughes
  • The Development and Use of Online Oil in Water Monitoring for Normally Unmanned Platforms, Andrew Hyde, INEOS Oil & Gas
