The PVT (Pressure-Volume-Temperature) properties are crucial in various industries, particularly in integrated hydrocarbon (oil and gas) industries, environmental engineering, carbon capture and storage (CCS), and hydrogen value chains. PVT data provides essential information for flow in porous media from reservoir simulation to simple analytical models, to well design, and integrated production optimisation, ultimately influencing decision-making processes in the extraction and processing of hydrocarbons. Its importance lies in ensuring efficient and effective resource management in the energy sector.

Wide spectrum of reservoir fluids has been discovered in Oman which spans across all different fluid types that are observed worldwide—light, heavy, volatile oil, dry gas/rich gas condensate reservoirs. In a way, the fluids being produced in Oman not only represent the worldwide portfolio of fluid diversity but also represent a variety of recovery processes that require understanding the complex fluid phase behaviour. Much of the complexity is related to the maturity of the reservoirs and the implemented recovery improvement measures—enhanced oil recovery, EOR, techniques—which introduce non-native processes. Many times, such recovery improvement processes lead to changes in-situ compositions and/or fluid properties. PVT analysis is instrumental to many of the screening processes and as well as for the implementation of the recovery improvement methods, EOR processes. Once a particular EOR method is selected, PVT data relevant to the EOR process aids in designing and optimising implementation/operational and as well as surveillance strategies.

Understanding how reservoir fluids respond to changes in pressure and temperature and introduced compositional changes is crucial for selecting the most effective injection fluids, managing displacement mechanisms, and maximising oil recovery. PVT analysis guides the development of tailored improved oil recovery techniques, contributing to increased hydrocarbon extraction from reservoirs.

With the growing emphasis on energy transition, CCUS alongside hydrogen stands out as two low-carbon solutions intricately linked to the thermodynamic and transport properties of CO2 and H2, especially in the context of providing solutions leveraged by our collective experiences from the integrated hydrocarbon industry and as well as the real potential for reusing/repurposing the currently existing surface and subsurface infrastructure. The distinctive aspects of fluid storage and extraction in diverse mediums, such as salt caverns and depleted gas reservoirs, coupled with the challenges of transportation involving impurities and hydrocarbons, present challenges that prompt the exploration of innovative solutions. Furthermore, addressing the substantial thermodynamic changes associated with wells managing CO2 injection is a pivotal area demanding new solutions compared to traditional hydrocarbon wells.

The theme of the workshop is Complex Reservoir Fluids—PVT in Brown Assets Towards Energy Transition and Improved Recovery, which will focus on exploring complex fluids from measurements and modeling to encompassing advanced techniques and applications in understanding fluid behaviour. Topics include computational methods, experimental measurements and validations, and real-world implications for industries such as hydrocarbon extraction, CCUS and hydrogen value chains, chemical, and environmental engineering. Join us for in-depth discussions on cutting-edge research and collaborative opportunities in the field of complex fluids for a variety of applications.
