Why we were contracted
Following the shut-in of a 2800-meter-deep offshore production well caused by a failure of the production packer (the primary barrier between the reservoir and the annulus), the operator required a safe and efficient solution for re-instating the well to assure production targets could be met.
Due to the excessive cost and time associated with using a conventional hydraulic workover unit (HWU) to execute the scope, the use of new technology and a highly experienced well service team were critical to enable a rigless intervention and reactivation in a safe, time efficient and cost-effective manner.
About the downhole technology used on this project
The technology implemented within the return to service campaign allowed an existing failed production packer to remain in place with a new primary sealing barrier installed directly above.
The new barrier was installed by drilling a series of holes in the 7” Production Tubing and deploying sealing technology via wireline tooling into the ‘A’ annulus. The sealing technology was then activated via Thermite Heater to form a solid metal plug that was then successfully pressure tested in the direction of flow.
The value we added
Successfully re-instated the well
Through the implementation of new downhole technology, we were able to successfully bring the well back online in a timely and cost-effective manner, without compromising safety barriers or well flow
Reduced cost by over $30M USD
Utilizing new downhole technology and a team of dedicated well engineering specialists, we were able to reduce the cost of the intervention by over $30 million USD
Reduced scope execution time by 66%
Without the need for a hydraulic workover unit, we were able to reduce the project timeline from 18 months to 6 months
Minimized risk
We were able to minimize risk through the removal of a complex conventional method (hydraulic workover unit) and avoid any excessive delays to the project due to effective contingency planning and preparation
Compliance with regulations
Our experts assured the project execution plan aligned with NOPSEMA, the local regulator’s requirements to obtain approval for the project within the required timeframe
Eliminated the burden of work
With in-house resources focused on critical day-to-day operations, the client received access to a highly trusted, competent, and dedicated team to manage the end-to-end process from planning to closeout on their behalf
