Technology Focus: Completions (April 2025)

For several years now, the energy industry has been actively working on solutions and technologies to support sustainability aspirations. Whether for a company or a country, most efforts were put into alternative or renewable energy research and development and in reducing flaring and venting intensity. While the industry has shown great progress in these areas, there are still many areas that could contribute to sustainability aspirations, one of them being well completions. It is refreshing to see now that sustainability is taken as an important element in developing completion technologies. These technologies affect the environment on different levels. Solutions can be as simple as technologies that reduce rig time and lessen diesel consumption, but they also have evolved toward full electrification of well completion design and surface facilities. A great example of how well completion technologies can evolve can be found in paper OTC 35379. A full-scale electrification of a completion concept was well thought through, covering enhancement on reservoir management, development of multizonal wells with more precision, overall well-delivery optimization, life-of-field management, and how all these contribute toward lower CO2 emissions. The concept is meant not only for conventional field development but also for carbon capture and sequestration projects. A full end-to-end design concept such as this will move the needle in managing greenhouse-gas (GHG) emissions. The extent of completion technology evolution does not stop with hardware and well design. Paper SPE 219258 pushes the limit by transitioning from conventional perforation methods into using high-powered lasers (HPL). Although it seems a just small facet of completions, perforation with HPL has positively affected GHG emissions, asset integrity, water consumption, surface footprint, operational logistics, and safety. There is also a good balance between the long-term and near-term focus on sustainability. Technologies such as HPL and ideas such as full-scale electrification take a considerable amount of time to develop, but paper OTC 34885 is about what can be done now. Focusing on completion operation optimization, the authors found that designing and challenging the status quo of the double-barrier requirement during operations resulted in qualifying a modified tubing hanger design as a certified double-barrier plug. This has led to interventionless completions, thus reducing rig-operation time and eventually reducing diesel consumption and carbon emissions. What really amazes me in these developments in the completions discipline is the fact that the solutions are coming from different parts of the world—from Brazil to Saudi Arabia to Malaysia. With such a global sustainability focus, the effect that completions technologies have on achieving the UN’s Sustainable Development Goals will be more evident in the near term.
