According to the U.S. Energy Information Administration (EIA) latest energy outlook, natural gas production and consumption will continue to increase over the next decades. As natural gas burns cleaner than coal or petroleum products, in addition to more countries begin adopting a policy to reduce carbon dioxide (CO2) emissions, the demand of natural gas may be further accelerated to replace more carbon-intensive coal and liquid fuels. Conventional gas reservoirs are high-permeability reservoirs that can be produced by traditional completion and stimulation methods, while unconventional gas reservoirs are usually low permeability reservoirs that require special completion, production, and recovery methods beyond the conventional development practices. Whether conventional or unconventional, each gas reservoir is unique in its character and performance. As such it needs a customised design to help maintain and increase gas production as well as improve development efficiency and economics.
This session explores the application of innovative technologies, novel well designs and field development concepts to reduce costs, increase production and improve reserve recovery in various types of gas reservoirs, including tight-gas sands, shale gas, coalbed methane, water-soluble natural gas, and gas-hydrate deposits.
Naturally occurring methane hydrate deposits under deepwater or permafrost are regarded as “possible” unconventional natural gas resources. However, technologies for economical production of them have not been fully established. Some recent research activities, majority of them done in the Asia Pacific and Indian Ocean regions, stimulate the development of this quite abundant but challenging resource target. Research issues exist in the basic science of their origin and accumulation, exploration techniques, production methodologies and technologies to be employed, and environmental implications. Some new ideas can be applied to laboratory and analytical techniques, interpretation of log and seismic data, subsea technologies, monitoring devices, geomechanical effects on stability of formations, computer aided modelling and simulation, attempts for actual gas production, carbon cycling, environmental change, geohazards and other technical aspects to study the resources.
The session invites broad communities of people – scientists, G&G specialists, petroleum and mechanical engineers, oceanographer and environmental specialists – but focuses on the application of science and technology for the development and production from methane hydrate reservoirs.
The session shall cover the following aspects:
- Methane hydrates development
- Methane hydrates reservoir and characterisation
- Methane hydrates wellbore construction
- Production testing and monitoring wellbores
- Natural gas production from methane hydrate deposits using CO2 sequestration
Although it has been said that our gas industry is behind other industries in terms of digital maturity, we are steadily catching up.
With smarter sensors, wider connectivity and ever-greater computing powers, we are able to conduct real-time modelling, drilling control, production monitoring, and many other gas related workflows, and deliver those anytime and anywhere through the Cloud.
In this context, gas companies are increasingly focused on digital technology and have quite a few initiatives on-going under the Chief Digital Officer. The Digital Shift for our industry is now playing out.
In this Digital Shift, digital technology helps connect all components across the value chain and break down silos within organisations. This enables convergence across the board while offering innovative solutions.
See and hear how the organisations are adopting digital technology to unlock new opportunities and facilitate shifts into new levels of gas business in the digital era.

The application of “Gas Utilisation Technology” in petroleum resources development is increasing due to the demand for environmentally sustainable field development. The role of “Gas Utilisation Technology” is significant to ensure the efficiency of field development, to enhance gas utilisation and be one of the counter-measures for the on-going climate change.
This session discusses the application of “Gas Utilisation Technology” such as CCUS / CO2-EOR, HCG-EOR, Gas Injection, Gas Compression Technology, globally and share the experiences for the growing application demand in the foreseeable future.
Supported by the recent increase in demand for LNG by emerging countries like China, India and South-East/South Asian countries, LNG is playing a bigger role as one of the main energy resources for the future. Japan has a long history of more than 50 years as an LNG importer and has acquired knowledge and lessons learnt which can be utilised by emerging countries.
This session introduces the latest LNG technologies such as small/mid/large scale LNG liquefaction facility and more, to further enhance LNG industry.
Emerging LNG importing countries located in East Asia, South-East/South Asian are considered to be potential demand growth centres in the future. However, the key to unlocking LNG demand in these markets require strategic approaches in achieving affordable and flexible LNG supplies. One of the key focus areas is cost reduction using innovative solutions across the value chain. For instance, utilising the Floating Storage Regasification Unit (FSRU) technology that results in shorter lead time with flexible and affordable LNG imports across those regions. In addition, increasing LNG demands from small-scale users, whether in remote inland/island locations, have started to gain attention from major oil and gas operators – inspiring them to implement innovative logistic solutions.
Another hot topic in LNG demand is its use for transportation. To tackle climate change and pollution, LNG is considered a promising fuel for ships, trucks, buses, and heavy-duty construction equipment. In those applications, innovative solutions are once again essential for wider use.
This session explores the latest technical applications for emerging demand creation in the following focus areas:
- LNG transportation, storage, regasification and gas distribution
- Small/Micro LNG distribution to island and inland location
- Pipeline/Virtual pipeline
LNG as transport fuel
- LNG bunkering
- LNG/gas fuelled vehicle
It is necessary to ensure that the risks to the environment are understood clearly to properly eliminate any that adversely affect the environment significantly in a professional, safe and environmentally responsible manner. This session discusses the following topics to help implement a more environmentally friendly operation.
Gas flaring reduction
Gas flaring reduction is one of the key environmental priorities for oil and gas operators globally. One of the innovative ways to resolve this is through the implementation of Flare Gas Recovery (FGR). Recovered waste gases can be put to valuable commercial use – gas injection for EOR, mini-LNG, Gas to Wire and more. These result in reduced emissions and cost optimisation.
Many gas reservoirs encounter development difficulties due to large quantities of impurities such as H2S and CO2 contained in produced gas. Even small amount of impurities have potential adverse effects on facilities, environment and safety. Recently, advanced technologies for removal, re-fining and re-use of CO2 have been developed. With regards to CCS and CCUS, it can be more economically viable to use CO2 for EOR rather than disposal in matured oil and gas reservoirs.
Operating practices for environment
Survey, drilling, production and whatever kind of operation in oil and gas fields cannot be conducted without adequate safeguards for environment and lives. It is necessary to continue to develop and refine operating practices to minimise and eliminate environmental impacts.
