The recent collaboration with OGIC and academic expertise at Aberdeen’s Robert Gordon University has enabled technology services company, Resolute Energy Solutions, to develop a more cost-effective method to better fill formation and annular void spaces.
Current industry challenges with P&A include insufficient barrier materials and high costs relating to rig time or having to reinstate derricks to conduct P&A operations. With the necessary support and funding from OGIC for the initial phase of this project, Resolute Energy worked with the Petroleum Engineering Research Group at Robert Gordon University to conduct essential research and development work. This included conducting physical tests to develop the most appropriate swellable sealing materials for downhole applications that meet specific industry standards.
Iain Lees, Director of Resolute Energy Solutions said: “Cement is the traditional barrier for plugging wells for abandonment, but this can have drawbacks due to its fixed and fragile nature. Our additive solution enhances cement and other sealant materials by adding energy and forcing the barrier to fully fill void spaces. This prevents leak paths from forming in formation tubing, annular spaces and behind casing. Tubing can also be left in place during P&A – all of which has the potential to significantly cut decommissioning costs.
“The Oil & Gas Innovation Centre has certainly lived up to their name with the support they have provided Resolute. We started the business by looking at a significant industry problem, and with the help of OGIC we are now taking it from concept to cure.”
