Obiz Pakistan The Pioneer in IWCF Courses in Pakistan

IWCF Well Control 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 participant.

Registration for the course may be sought by filling the registration form along with a cheque/bank draft/cash of US$2,200/- in the name of Obiz Pakistan (Pvt.) Ltd.

Full fee will be refunded, if and 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.
