Exceed specialise in delivering well management and well performance improvement solutions for the upstream Oil & Gas industry.
Based in Aberdeen we operate globally, supporting client projects across the entire well lifecycle – from concept to completion, integrity and intervention, workover and end-of-life decommissioning.
Our primary focus is on supporting clients in safely delivering projects that meet their objectives.
This track record of managing complex wells projects in both domestic and remote global locations relies on our in-house competency and capability, our ISO 9001, 14001 and OHSAS 18001 certified management system and our well construction/abandonment delivery process which ensures consistency of delivery and allows Exceed to assume the role of well operator for UK EU-based operations.
Exceed has been at the forefront of large scale well abandonment operations with its well management division providing well plugging and abandonment engineering services to Fairfield Energy for its 45-platform well Dunlin and 16 subsea well Osprey/Merlin campaigns and additionally its performance improvement division providing support offshore to Centrica on the A field abandonments (7 x SNS Subsea wells), Repsol Sinopec on its Beatrice Bravo and Charlie campaign (13 wells) and Maersk on its Janice and Leadon abandonments.
This ongoing portfolio exposes Exceed to most of the decommissioning environments and the associated technologies: this includes platform wells / subsea wells /NUI platforms using jack-ups, conducting SIMOPS including dive vessels as well as the novel use of jack-ups to conduct subsea well abandonment
Engineering cost and feasibility studies covering several international basins have also been completed over this period including asset transaction due diligence, focussing on decommissioning liability.
The well abandonment section of the decommissioning arena, particularly large-scale campaigns, is at a relatively early stage of evolution and innovative technologies are continually emerging and improving.
The key challenge that many well abandonment teams will face is the effective management of risk and change. In many cases the wellbore integrity may not meet expectations resulting in change and introduction of contingency plans.
Critical to success is the front-end planning incorporating the latest best practice to develop the decision trees and contingency plans to address the probability of an event and consequence.
The introduction of new technology versus traditional field proven methods should deliver a safer more cost-effective result but it can introduce new risk and there may be an investment cost of failure in order to evolve the technology to commercialisation.
It is a revolution that needs to include all stakeholders and the willingness to constructively challenge guidelines where evidence supports that an alternative approach may be taken and responding in real time to results and lessons learned to drive forward best practice in the field without the introduction of new risk
Being involved in multiple projects in an industry where no two wells are the same, and where most were designed without longer term consideration to final well
abandonment has provided Exceed with the ability to assess this risk and evolve its well decommissioning service, ensuring maximum efficiency and adequate resource is utilised.
It has also allowed us the opportunity to attain in-depth understanding of the current field-proven and new and emerging technology on offer, review performance and work with suppliers to improve efficiency.
Finally, it has allowed us to conclude that in well abandonment one size does not fit all and each project will have unique para-meters which will require bespoke solutions to be developed and these solutions should be iterated plug to plug, cut to cut and well to well to improve well abandonment performance.
