Course Length:  5 Days
Course CEUs:  4.0

Course Description

Development Geophysics is a MUST HAVE course for geophysicists, geologists, engineers and managers involved in field development. In field development there is more seismic data available than in exploration, so a higher level of detail and reliability is achieve from the seismic data. This course examines geophysical techniques that lend themselves to optimizing reservoir production.

People wanting to use seismic attributes to measure reservoir properties need to attend this seminar. This seminar instructs and illustrates the use of seismic attributes to measure reservoir properties. Geophysical data are used in development and production projects as much or more than in exploration applications; therefore, geophysicists and non-geophysicists working in production and development must be familiar with the interpretation and understanding of geophysical data and interpretation techniques that are applicable to reservoir development. This course shows how geophysics is used to enhance knowledge of the reservoir.

In this course participants learn to calibrate geophysical data to a particular reservoir characteristic and then use the geophysical data to measure reservoir properties such as thickness, porosity, feet of porosity, feet of pay, percent sand or fluid type over a reservoir. This course describes geophysical techniques that are applicable to measuring reservoir properties to maximize reservoir production. In the seminar workshops, participants apply these techniques to real seismic data in development situations and gain a working knowledge of how to apply geophysical techniques to measure reservoir properties.

Learning Outcomes:

  1. Gain an appreciation of the importance of calibrated seismic data in exploitation and development work
  2. Develop an understanding of how synthetic seismograms and seismic trace inversion are used to correlate log and seismic data
  3. Gain an understanding of how AVO is used to detect hydrocarbons in the subsurface
  4. Develop an understanding of how log editing and seismic data processing enhance the correlation between the two data sets
  5. Gain an appreciation of how seismic attributes can be used to estimate changes in a reservoir property away from a well bore


Who should attend:

Geologists, engineers, geophysicists and managers who are working with geophysical data developing oil and gas reserves.
