Argus Subsea Launches New Subsea System for Jack-Up Mobile Drilling Units
Argus Subsea announced the introduction of the AZ-15J subsea tree and wellhead system. Specially designed for jack-up mobile drilling units, the Argus AZ-15J is the world’s first purpose-built system that allows operators to drill and complete wells up to 15,000 PSI working pressure without special riser systems or cumbersome temporary abandonments.
The Argus AZ-15J provides an easier installation experience for operators, which takes less manpower and leads to safer, more cost-effective production applications than with conventional mudline suspension systems using wellheads adapted for horizontal or vertical tree completions. The well is drilled with conventional casing program to total depth, gravel packed and the tubing hanger is set and tested in the wellhead prior to breaking back all tie back strings. After the tie-backs are retrieved, the subsea tree is run landed, tested and left with the appropriate barriers in place before the tieback is made to the host facility.
The AZ-15J requires only minimal tools to install, versus the large amount of tools for a typical vertical or horizontal tree adapted system. The AZ-15J mono-bore vertical tree weighs less than 45,000 pounds and can be handled by all cranes without disassembly. These features provide for smaller crews and fewer third-party services.
"The innovative AZ-15J subsea tree will enhance the development of shallow water marginal fields where time is critical and fast-track deployment can lead to millions of dollars of increased profitability for the operators," said Carl Aubrey, General Manager of Argus Subsea. "The AZ-15J can save a minimum of 15 days rig time as compared to the current industry standard drilling and completions time."
The AZ-15J features a patented universal tubing hanger and a running tool system that allows for streamlined drilling and completions. All of the AZ-15J components and assemblies have been designed and validated using API specifications 6A and 17D under the API Q-1/ISO 29001 Quality System Standard requirements. They also comply with applicable MMS requirements such as API Specification 6AV1, one of the industry's most stringent testing standards for subsea valves and actuators.
