Course Objective
The curriculum identifies a body of knowledge and a set of job skills that can be used to provide well control training for Wireline operations personnel.

Course Design

• Power Point© / Lecture / Audio Video / Visual Aids
• Demonstrations
• Practical Simulations Exercises
• All students are supported with Laptops for online reviews, sample testing, support material, manuals and data sheets. Testing is online controlled by IADC thru their website. All support material is soft copied to each student thru thumb drives.

Successful Course Completion

• Requires a minimum score of 75% or better.
• Delegates will have no more than three hours to complete the exam.
• Grades shall be calculated online by IADC and be proctored by Llyod’s Registry personnel, all questions are multiple choice.
•  An Immediate retest after review is available or within 45 days of the initial test failure.  The delegate must score a 60% or better to qualify for the re-test option.
