Actual oil production is at its peak, but investments in drilling equipment do not need to be made, as there is sufficient capacity available on that side, and service sector companies do not foresee a new boom or abundant cash flow, because the current oil price does not encourage a large number of additional drillings. Service-side companies are rather going bankrupt globally, including in the United States.
An easier comparison for Finns to understand would be, for example, the sale of a new innovative paper machine solution to Finland over the last 10 years. Not even a good solution helps if new investments are not necessary.
