Reservoir Characterization Challenges and Case Studies
Naturally fractured tight sands reservoirs that host a significant proportion of the region’s gas reserves, can be very complex and heterogeneous, leaving room for significant uncertainty. The importance of the dual porosity model as a representation of the natural fractures, the analysis of flow of the matrix to fractures, fractures as channels of high permeability flow, or flow barrier, are key elements of analysis. This session will cover the main methodologies, best practices, new process and workflows, and technologies that support state-of-the-art in reservoir characterization and engineering.
The integration of seismic, geology, and well data will be shown as a key element in reducing the natural and distinctive uncertainty that fractured reservoirs bring to the subsurface studies. Regional examples that frame case studies in geo-statistics and modeling for sandstone reservoirs will also be presented, showing the positive or negative impact fractures can have on production performance.
Reservoir Engineering Challenges and Case Studies
Discussion continued from Session I as related to challenges encountered in reservoir engineering.
Field Development Strategies and Production Challenges
One of the most difficult aspects of planning high well productivity field development is quantifying and establishing the volumetric associated with production levels during the life of a naturally fractured tight sands field. The planning strategies used to analyze production must face a high level of uncertainty presented by the presence of fractures and other characteristics for these reservoirs. This session will present lessons learned, state-of-the-art technologies, new developments and best practices used to mitigate uncertainties in field development of high well productivity reservoirs.
• Development options and strategies for naturally fractured tight sands reservoirs
• Early stages of data acquisition—well test
• Permanent data monitoring—reliability
• Water conformance techniques
• Managing uncertainties: next generation integrated modeling and simulation tools
• Well and reservoir management
• Intelligent completions—selective production
• Remote oilfield management
• Logistics challenges—planning

Discussion continued from Session III.

Drilling Challenges and Lessons Learned
Drilling muds causes large irreversible damage to open fracture networks and leads to low production of wells. This session will discuss drilling challenges in the region of the south of Sub-Andean with fractured reservoirs and will include the following topics:
• Applicability of new drilling technologies for fractured reservoirs
• Applicability of new drilling technologies to drill carboniferous formations
• Well design in fractured reservoirs (trajectory, placement, geo-steering, under-balance drilling)
• Drilling fluid selection for interested intervals (non-damaging, solids control, under-balanced)
• Perforation and stimulation techniques
• New technologies in drilling for gas reservoirs
• Case histories in drilling for fractured formations
Drilling Challenges and Lessons Learned (Part 2)
Discussion continued from Session V.
Completions Challenges and Lessons Learned
This session will discuss challenges and lessons encountered during the design, execution and evaluation of the completion type implemented in the deep gas wells in fractured reservoirs. An inaccurate completion selection causes irreversible damage to open fracture networks which leads to low production of wells. The session will cover:
• Strategies for completions in fractured reservoirs
• Down hole pressure and temperature monitoring techniques
• Down hole rates monitoring techniques
• Production bottom hole system integrity monitoring
• Intelligent completions
• High gas rates wells completion
• Multi phase flow meters
• Telemetry and tele-commands
Completions Challenges and Lessons Learned (Part 2)
Discussion continued from Session VII.
