Features of PTA in horizontal wells with multistage fracturing and multilateral wells
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;
|Introduction. Types and ways of well testing in horizontal wells with multistage fracturing
