Sound speed. Correlation tabulation and measurement interpretation.
The purpose of this webinar is to give structured knowledge about well testing and its interpretation to measure sound speed in the annulus. To consider the necessity and purposes of such testing, tools and instruments, possible complications and their solutions. Training is conducted in the form of audiovisual delivery (presentation) and subsequent discussion and answering trainees questions.
- quality improvement of sound speed testing;
- improved monitoring of field development;
- cost saving on ineffective measurements and testing;
