Stimulation Technologies (PRE15)

24-27 April 20234 daysVienna, AustriaCourse Fee: 3100 EUR + VAT

Description

This course covers the main aspects of Acid Stimulation Techniques. The course focuses both on theoretical concepts and practical onsite experience.
Acidizing with Coiled Tubing will be also discussed in detail, due to its importance in acid placement and formation treatments.

Course Level: Skill
Instructor: Antonio Abreu, Luis Remisio, Cipriano Costa
