SPE High CO2 and H2S Gas Fields Development

18–23 May 2014 :: Bali, Indonesia


Technical Agenda

Standards and Regulations Associated with High H2S and CO2

Session Chairpersons: Syahrini Mokhtar and Ronald Sweatman

This session will discuss current and proposed standards and regulations for wells with high H2S and CO2 flow content. Effective and efficient H2S and CO2 management is required to meet current/future legislative and environmental requirements for well planning, construction, and production/injection/abandonment operations.  Topics to be discussed, among others:

  • Are we ready with the relevant regulations and standards in design, execution and operations of these fields development?  Are there relevant and comprehensive standards by ISO, API, etc.? Will the regulations hinder these fields development?
  • Development of relevant regulations prior to projects proceeding on a significant scale and the linkage with existing oil and gas regulations in the area of CO2/H2S transport and storage i.e. South East Asia vs. European/developed countries.
  • Long term measuring/monitoring/verification (MMV) requirements.
  • Managing host country and NOC/IOC’s commitment towards superior health, safety, and environmental performance.
  • International laws on protection of marine environments.

Subsurface Development and Resource Evaluation

Session Chairpersons: Michael Carne and Andry Halim

High CO2/H2S content of gas impose different challenges to normal subsurface procedures and workflows used in reservoir description, fluid characterisation and phase behaviours, compositional variation and grading, reservoir souring, and other associated production technologies. In addition, reliable static/dynamic modelling, uncertainty analysis and risk mitigation plans both on the development and CO2 injection/sequestration and associated geomechanical and geochemical aspects need to be incorporated for the success of the development plan. This session will elaborate on various critical subsurface aspects from reservoir characterisation to resource/reserve estimation of high CO2 and H2S gas fields.      

Integrity Management and Flow Assurance

Session Chairperson: Carlos Menendez

This session will focus on the main equipment integrity and flow assurance issues that gas production currently faces and will be facing in the presence of rich in H2S and CO2 gas streams. With the exploitation of ever deeper reservoirs onshore as well as offshore, such topics like materials selection, corrosion control, monitoring of chemicals performance, solids deposition control and hydrates formation prevention can become quite challenging tasks. The management strategy needs to recognise the importance of overcoming these technical challenges since these environments can pose significant health, safety and environmental impacts. Some of the technical areas that will be addressed include the use of new alloys, coatings, composites and nanotechnologies during the materials selection process and the use of such specialty chemicals as corrosion inhibitors, H2S scavengers, FeS dispersants and hydrate inhibitors.

Capture/Separation Technology

Session Chairpersons: Sukor Ahmad and Azmi Mohd. Shariff

This session will introduce discussion points on the future needs of new technology. Cryogenic, supersonic, membrane and amine are the current and emerging technologies in capturing/separating hydrocarbon from H2S and CO2 for gas fields with high H2S and CO2 contents. The session will delve into the maturity level and potential benefits of these new technologies, from users point of view. What are the strategic implications and potential impacts? Addressing the key challenges and issues towards the field application in technology development are crucial in minimising the risks. How far the technology have been validated and demonstrated? What is the threshold of volume or content of H2S and CO2 from the reservoir, considered uneconomical to develop the high H2S and high CO2 fields?

Disposal and Utilisation

Session Chairperson: Ku Azhar Ku Akil

Development of high H2S and CO2 fields proves to be technically, physically and economically challenging as it requires serious consideration for the management, transportation, storage and utilisation of the acid gas. The industry must work hand-in-hand with the authorities and regulators early in the project stage to come up with mutual agreement and meeting all the required standards and requirements. This session will focus on the issues, technologies, economics, and forward looking with regards to the disposal and utilisation of the acid gas.

Sour/Acid Gas Monitoring Technology

Session Chairpersons: Nor Azila Mohd. Salleh and Zhengwei Liu

With the increasing development of gas fields with high H2S and CO2 content, advanced technology is required to quickly and precisely determine the type, concentration and distribution of sour/acid gases. Sour gas monitoring technology is critical in the success of sour gas management from near wellbore, to production systems, and on to disposal sites. In this session, best industry practices in design and operation of sour gas monitoring systems, as well as current and emerging monitoring technologies will be discussed; the focus areas of discussion being large scale monitoring system automation, sampling techniques & procedures, and new sensor technologies.

Knowledge Management and Skills Development

Session Chairperson: Sukor Ahmad

While cost-effective technology is a critical factor for the economics of acid gas development, factors like the availability of experienced engineers should not be neglected. Threats surrounding these types of projects, both for the people and environment, mean that safety management systems, risk mitigation knowledge and skills are critical. Given the speed at which the technologies are changing today, companies may have to deepen collaborations with educational institutions around the globe to ensure industry requirements are met. This session will cover discussions on gaps between current practice and the future desired state, and what can be done to improve awareness of acid gas field development; this includes skill development and training, and a knowledge sharing framework within the community.
