Wellsite and Operations Geology (GEO13)

  • 24-28 September 20175 daysAbu Dhabi, UAECourse Fee: 4500 USD

Description

This course teaches both fundamental and more advanced elements of wellsite and operations geology.
First, a review will be made of the background and some of the basics of these related disciplines. The course will then detail each of the main duties and responsibilities of operations and wellsite geologists. These will include well planning and surveillance, selection and quality control of the geological contractors, the ever increasing task of data management and formation pore pressure evaluation. There will also be detailed reviews of the more traditional tasks of sample and show description as well as coring and sidewall coring.

Course Level: Intermediate
Instructor: Tim Herrett

Designed for you, if you are...

  • Familiar with the basics of wellsite and operations geology and want to learn more details about these disciplines
  • An oil & gas company geologist, as it will give you valuable insights into the process of well planning, wellsite data acquisition, the value of the data, its limitations and its use in regional studies and well planning

The course assumes some basic knowledge of rigs, rig equipment, drilling activities and the personnel involved in these activities.

How we build your confidence

You will be taken along a path which gradually introduces each topic and uses many graphics / photos and some videos to illustrate the points made. The manual provides a good future reference for what has been taught in the course.
