  • Unconventional Shale Gas Evaluation

Date Duration Location  
02-Jul-12 4 days Bandung, Indonesia -


Course Overview
 
 
Shale gas is becoming an increasingly important source of natural gas in the United States over the past decade and is expected to grow further in the coming future. One analyst expects shale gas to supply as much as half the natural gas production in North America by 2020. This interest in shale gas has since spread quickly to the rest of the world as countries seek to produce more shale gas to reduce their dependency on foreign imported gas.
 

This masterclass will provide a thorough understanding on the evaluation of shale gas and oil reservoirs from various perspectives (geological, geophysical, geochemical and petrophysical) and how to classify and estimate unconventional gas reserves accurately and precisely. Delegates will learn to evaluate the various black shales, as shale-gas & shale-oil targets, as well as predicting locations of quality shale plays. The course will also present on successful shale-gas/shale-oil plays in the US, Canada and other places in the world.
 
 
A short presentation on other unconventional gas and oil types (tight sandstone-gas, Bakken Play) will also be included. Project exercises and case studies based from the trainer’s past experience will also be covered extensively to allow delegates to gain practical experience from this masterclass.
 
 
Course Objectives:
 
  • GAIN insights on the economic potential and importance of natural gas worldwide
  • RECOGNIZE the emergence of unconventional shale gas resources
  • UNDERSTAND about the different types of black shales, their deposition and their distribution
  • EXPLOIT different types of unconventional petroleum from black shales
  • APPLY the principles of petroleum system analysis and prospects evaluation on unconventional shale gas reservoirs
  • EVALUATE the potential and productivity of shale gas reservoirs from various perspectives
  • ESTIMATE volumes and CLASSIFY unconventional shale gas reservoirs accurately
  • ANALYZE the petrophysical parameters of shale-gas & shale-oil reservoirs
  • UNDERSTAND about other unconventional gas types, like tight-sandstone gas
  • BENEFIT from successful shale-gas and shale-oil plays in the world, including the US and Canada
 
This program is intended for:

• Exploration Geologists
• Explorationists
• Geoscientists
• Geophysicists
• Reservoir Engineers
