Description

Designed for you, if you are...

• A well-site geologist, drilling or operations engineer
• A professional involved in the acquisition and use of well-site (geological) data

How we build your confidence

The benefits from attending

• Understand the techniques used by wellsite geologists in formation evaluation via:
  - quick-look analysis to assess reservoir and hydrocarbons
  - mudlog data (lithology/cutting description, gas readings)
• Grasp the application of wellsite data in exploration and development
• Read and use drilling reports
• Acquire an understanding of the drilling problems caused by subsurface conditions
• Understand the role and contributions of the geologist to the well maturation process
