COURSE OVERVIEW
This course is designed to help perform acidizing on a well candidate in a logical step-by-step process and then select and execute an appropriate chemical treatment for the oil/gas well. The subject matter is practical in intent and avoids the more complicated acid reaction chemistries. Effective acidizing is guided by practical limits in volumes and types of acid and procedures so as to achieve an optimum removal of the formation damage around the wellbore.

INSTRUCTOR
Jerry Rusnak
Jerry Rusnak has more than 40 years of oilfield experience. He has worked in all phases of the industry including service, supply, operations and academia. He began his career as a Wireline field engineer. Then he worked for an Independent Exploration and Production Company as a field engineer managing wellsite drilling, completion and workover operations. Moving up he became the companies Drilling and Completion Manager in charge of multiple simultaneous drilling and completion operations across US land. At the end of his tenure (15 years) he was the company’s Exploration and Production Manager. This company grew rapidly during his career and the E&P part of the company was eventually sold to a major independent . Rusnak holds a Bachelor of Science degree in Ocean Engineering from Florida Atlantic University, is an active member and past section president of the Society of Petroleum Engineers (SPE) and holds or is eligible to hold most major certifications required for wellsite work both onshore and offshore.
