After seven years of hard work and more than $150million of investment, Expro’s deepwater intervention system is here.
The AX-S system is a revolutionary technology which has been developed with inherent safety aspects, to deliver an efficient
cost-effective system designed to extend the operating envelope for subsea well interventions in up to 10,000ft of water- far beyond the current limit available today.
Our vision is to deliver a full range of wireline intervention services to your subsea wells at a 1/3rd of the cost of a comparable rig today.
There are approximately 4,000 oil and gas producing subsea wells across the globe, and this number is increasing. With many now more than decade old, intervention is crucial to extract all possible recoverable oil. AX-S aims to close the value recovery gap between subsea and dry-tree fields by providing a safe, riserless, remotely operated subsea well intervention solution.
The AX-S (pronounced ‘access’) system is deployed onto a subsea tree with an active heave-compensated fibre winch from a monohull vessel, and is remotely controlled from the surface like a ROV. It consists of an integrated set of pressure-contained subsea packages comprising well control, wireline tools, wireline winch and fluid injection functions. A hydraulic plug-pulling tool overcomes the risks associated with pulling and setting tree crown plugs. A novel control umbilical overcomes the challenges of weight and size.
AX-S is safer because it is a pressure housing on top of a safety package. There is no stuffing box or grease injection. Back deck operations to swap tools are eliminated. It is only necessary to disconnect the control umbilical for the supporting vessel to leave location, leaving the system as an additional safety barrier on top of the subsea tree.
AX-S is more cost-effective because it is supported from a monohull vessel and is faster than wire-through-water solutions used in shallow water, especially on horizontal trees. Our studies indicate that AX-S is the only viable solution that is economically attractive for wireline intervention in deepwater wells. Expro’s subsea vision is driven by our customers’ needs to close the recovery gap between subsea and dry-field trees.
When comparing with rig-based interventions, the high operating cost and limited availability means that one operator in the Gulf of Mexico has budgeted about $35 million for a wireline intervention. Using the AX-S system would dramatically reduce these costs.
