Testing novel technologies, developing abandoned reservoirs and rejuvenating mature fields require top-notch technical preparation and fit for purpose risk exposure attitude. Even in case of the commercial availability of the right technology at the right time, studying a technological pilot and actually executing it highly depends on the risk exposure attitude of the management which plays a crucial role.

The history of Hydraulic Fracturing activity in Congo goes up to 2007; with the background of producers with very low or nil performance and the high costs of fracking offshore for the first time in the country, the risk of investment and technological failure was elevated.

At the time of the first pilot test in K-field offshore, the eni Congo management was not so interested in the immediate gains. The management was betting on eventual success of the technology, which would start a new era for the development of low permeability reservoirs in Congo and thus making a huge impact on the future of the company production and reserves.

This papers describes the lessons learnt in 5 years of frac operations in Congo with over 130 diverse frac operations (performed on different reservoir of diverse permeability ranges, green to brown fields, onshore to offshore, conventional single stage to multistage fracturing, acid and proppant frac with water base and oil base frac fluids). This paper would also serve as potential reference for all Operations Managers who are willing to optimize their assets value by means of Hydraulic Fracturing but face difficulties in winning mental barriers towards novel technologies inside or outside their companies.
