up to 15 people

The webinar is intended for specialists in the field of oil and gas field development and operation, who take part in conducting, interpreting, monitoring or checking well testing.

The purpose

The purpose of this webinar is to introduce features of conducting field operations and subsequent well testing interpretation in horizontal oil wells. Define the main concepts of new flow regimes compared with classical vertical wells; ways of their diagnostics and obtained results. Training is conducted in the form of audiovisual delivery (presentation) and subsequent discussion and answering trainees questions.


  • quality improvement of horizontal well testing;
  • improved monitoring of field development;
  • cost saving on ineffective measurements and testing;
