Preliminary Technical Agenda

Monday, 22 March 2010

10:00 a.m. - 12:00 p.m.

Session 2: Reservoir Drainage
Session Co-Chairpersons/Moderators: Azhar Al Kindi, Shell Upstream Intl.; Carl Stockmeyer, Baker Hughes

This session addresses key aspects of reservoir drainage for high rate gas wells. Understanding reservoir drainage links directly to well design and the infrastructure required for field development. An important challenge is balancing the drainage scheme, and associated well architecture, with the capacity allowance for individual wells. A longer term challenge is the assessment and mitigation of the impact of high rate well drainage on complementary development projects such as infill drilling and compression.

The session sub-topics will include:

• Drainage area evaluation.
• Optimal and cost efficient drainage pattern development.
• Managed Drainage as a risk mitigation.
• Planning future development for ‘High Rate’ reservoirs.
• New technology enabling maximum reservoir drainage designs.

1:00 p.m. - 3:00 p.m.

Session 3: Reservoir Management
Session Co-Chairpersons/Moderators: Azhar Al Kindi, Shell Upstream Intl.; Kamel Bennaceur, Schlumberger

This session explores critical aspects of reservoir management when being drained by high rate gas wells. Reservoir management objective have a direct impact on the basis of design for the entire system as well as post execution planning and life of field operating philosophy. The geological and dynamic factors which enable high rate gas wells call for good surveillance data in order to facilitate
robust reservoir management, performance simulation and performance forecasting. If high rates are maintained by allowing excessive drawdown, then diagnostic monitoring measures for near wellbore conditions may be required. For commingled high rate gas wells, additional reservoir management measures may need to be accounted for to monitor likely deferential depletion, preferential water
encroachment and to ensure proper production allocation.

The session sub-topics will include:

• Proactive and Reactive measures to safeguard costly production where a single well failure can result in major production shortfalls.
• Facilitating a robust performance simulation for high offtake reservoirs.
• Management of high rate commingled producers.
• New technology enabling cost effective reservoir management.
• Best practices in high rate gas well reservoir management.

3:15 p.m. - 5:15 p.m.

Session 4: Completion (Carbonate)
Session Co-Chairpersons/Moderators: Bill Sorem, RasGas Co.; Mark Van Domelen, Halliburton Energy Services

The goal of this session will be to share experiences and challenges associated with current practices used for the design, execution and evaluation of completions in high rate carbonate reservoirs. Of particular interest are new or novel technologies that are allowing for successful completions in this high rate carbonate formations.

The session sub-topics will include:

• High Capacity Completion Types and Methods – Monobore, Tubing and Packer, Cased Hole and Open Hole
• Perforating, Logging and Stimulation Techniques
• High Volume Well Testing and Cleanup Techniques
• Reservoir Monitoring and Assessment
• Reservoir Performance – Zone Coverage, Condensate Banking, Conformance
• Workover Techniques – Isolation Plugs, Non- Damaging Kill Fluids and Materials

8:30 a.m. - 11:00 a.m.

Session 6: Completion (Sandface Completion)
Session Co-Chairpersons/Moderators: Peter Adams, Kebabangan Petroleum Operating Co.
Sdn.Bhd.; Ian Mickelburgh, Schlumberger

The goal of this session is to share information and experience on completing high rate gas wells, with a particular focus on the sandface completion design. The session will target sandstone formations and design issues specifically related to sand producing formations. It will look at why specific sand control techniques have been chosen, and how they have performed to date.

The session sub-topics will include:

• Sand Management Strategy
• Sand Control Techniques
• Well Stimulation
• Zonal Isolation
• Completion Performance

11:15 a.m. - 1:15 p.m.

Session 7: Completion (Upper Completion)
Session Co-Chairpersons/Moderators: Stuart MacKay, Schlumberger; Stan Tan, Weatherford Intl. Inc.

The upper completion in a high rate gas well is typically kept as simple as possible; large bore safety valve, production packer, permanent monitoring and sometimes chemical injection. These components are expected to provide functionality with a minimum of OPEX over the design life of the well, which may be 20+ years. Because each well is a high production well, reliability is of paramount importance. High rate gas wells may present designand operation challenges such as those related to high fluid velocities, and specific materials requirements due to geometrical constraints, required performance envelope, well chemistry, or temperature. This session will review developments in upper completion component technology.

The session sub-topics will include:

• Qualification Testing for robust design
• Permanent Monitoring
• Installation without intervention
• Largest technically feasible design

8:30 a.m. - 10:30 a.m.

Session 8: Facilities and Technology (Subsea facilities)
Session Co-Chairpersons/Moderators: Wendell De Landro, Shell Intl. E&P Co.; Daniel Teng, Woodside Energy Ltd.

High rate gas flow together with the potential for free water and sand production introduces another level of complexity to remote subsea systems. This session will examine the areas affecting the design and operation of subsea equipment associated with high rate gas wells, which may be located in a remote, deep-sea and low temperature environment.

The session sub-topics will include:

• Subsea Tree Design for high rate gas wells
• Erosion Modeling
• Multiphase Flow Metering
• Water Production and Hydrate Management
• Sand Detection and Management

10:45 a.m. - 12:45 p.m.

Session 9: Facilities and Technology (Surface Facilities)
Session Co-Chairpersons/Moderators: Jeanette Roberts, Aker Solutions; Raymond Tibbles, Schlumberger

Surface facilities play an important part in ensuring reliable production of high rate gas. As gas developments become more challenging, and often located in deepwater and remote from infrastructure, the capital investment and design challenges associated with the surface facilities are critical for ensuring a successful development. Technology enablers include floating production facilities, closed-loop MEG systems, gas FPSOs and floating LNG.

The session sub-topics will include:

• Deepwater Technology
• Gas FPSOs
• Floating LNG
• Flow Assurance
• Hydrate Management
• CO2 Handling

Session 10: Operation and Intervention (Well Integrity and Reliability)
Session Co-Chairpersons/Moderators: William Martch, Shell Intl. E&P Co.; Jose Ricardo Solares, Saudi Aramco

The high cost of high rate gas producers, and the need to maximize financial return by keeping them fully operational, demands a very high level of well completion integrity and reliability because financial loss from production interruption can be catastrophic. As development of gas reserves from hostile reservoir environments continues to challenge long-standing practices, new and optimum practices and methodologies are consistently being developed and implemented throughout the industry. This session will focus on sharing best practices and lessons learned, implementation of new technologies, and review of industry trends to ensure well integrity and reliability in high gas producers.

The session sub-topics will include:

• Well Completion Strategies and Results
• Well Integrity Monitoring Practices and Long-term Assurance
• Equipment Selection Decision-making Methodologies

4:00 p.m. - 5:15 p.m.

Session 11: Operation and Intervention (Intervention Strategies)
Session Co-Chairpersons/Moderators: Michael Kersey, RasGas Co.; Indran Pathmanathan, Halliburton Energy Services

Intervention operations in high rate gas wells can often be complicated by high pressures, high temperatures, H2S, deviated well paths, and unique downhole equipment. Considering the cost and value of these assets and the consequences of formation damage or the loss of well control, thorough upfront planning and effective strategies are critical to successful well intervention operations.

This session will address workover strategies and experience with regards to:

• Workover Fluid Selection and Well Control Methodology
• Formation Damage Prevention and Remediation
• Stimulation and Surveillance in Highly Deviated Completions
• Well Design to Facilitate Intervention Activities
