A major offshore deepwater development in West Africa required a review of its original technical solutions to improve project economics and reduce the average lifting cost of hydrocarbons.
With Drilling & Wells CAPEX and OPEX representing a significant proportion of the development economics, THREE60 Energy was engaged to undertake a series of studies and feasibility reviews to identify opportunities for greater efficiency and cost savings.
Challenge
The client wanted to challenge the original development assumptions and identify technical improvements that could strengthen the project against future commercial uncertainty.
A particular focus was placed on drilling performance, well requirements and opportunities to reduce non-productive time (NPT), while maintaining well integrity.
Solution
THREE60 carried out detailed studies across the predefined focus areas, reviewing drilling performance and identifying opportunities to optimise operations.
The team developed nine technical solutions aimed at reducing NPT and improving drilling efficiency, assessing how changes to the original approach could support a more efficient and cost-effective development.
Result
The work contributed to a revised development requiring 12 wells rather than the original 14, alongside improvements to well integrity.
Combined with the wider technical enhancements identified through the studies, the revised approach delivered significant cost savings and helped improve the overall economics of the development.
