Demanding environment led to well integrity issues
A Congo operator faced many challenges, including multiple wellhead suppliers and inexperienced and untrained local personnel. The high pressures, high temperatures, and hydrogen sulfide (H2S) found in many of the wells had also taken its toll on equipment. With many installations in the region more than 40 years old, the operator decided to conduct a survey of its entire wellhead portfolio. Results showed that more than 65% of wells had integrity issues and production was not being optimized.
Refurbishment and maintenance program optimized equipment performance
The operator contracted Cameron to inventory, maintain, and install wellheads and gate valves, as well as supply new wellheads, gate valves, and Christmas trees. Since the partnership began, wellhead and gate valve maintenance and performance on 360 wells (up to 12,000 ft deep), distributed among 10–12 offshore platforms, has undergone rigorous examination.
