Certification Course (DRILLER/SUPERVISOR LEVEL)
This course, followed by IWCF
examination, will be conducted using a portable simulator, invariably covering
the contents approved by IWCF, by an IWCF accredited instructor/assessor from
Falcon Multi Services.
The participants will be awarded
IWCF certificates.
Course Duration:
Five days (four days training and one day certification
test).
Course Fee:
US$2,200 (US Dollar Two thousand Two hundred only) per

only if, Obiz cancels the course or changes the date for more than two weeks.
This course is designed for drillers,
tool-pushers, company representatives, drilling supervisors and rig
superintendents.
