Customer Challenge
In the ever-changing landscape of offshore exploration in the Republic of Congo, the Djeno sandstone formation remains a promising but uncertain interval due to rapid lateral facies changes. The limited seismic resolution at depths exceeding 40 meters impedes clear imaging of thickness variations and reservoir quality, leaving our client seeking solutions to assess lateral continuity and the feasibility of a new appraisal well. In search of a reliable partner, the client turns to Vulcania Energy for expert evaluation.
Solution
To address the challenges posed by the complex facies changes, we embarked on a comprehensive seismic reprocessing initiative. This involved enhancing noise suppression, removing multiples, and refining the current velocity model. The updated seismic interpretation of the Djeno interval unveiled a clearer understanding of the turbiditic deposit fan, revealing the source of sediments and indicating that the newly drilled well was strategically positioned on the distributary channel.
Outcome & Value Delivery
Through meticulous reprocessing, we achieved a breakthrough in identifying distinct thickness changes, providing crucial insights into the geometry of the turbiditic deposits. By pinpointing the channel-lobe transition zone, we uncovered a more promising prospective area, potentially yielding up to 97 million barrels of contingent and prospective resources. These new reservoir targets hold immense value, justifying significant CAPEX investments for the investor and its partners, and heralding a new chapter of success in offshore exploration endeavors. With Vulcania Energy as their strategic ally, our client gains an edge in navigating the complexities of exploration and unlocking untapped potential in the Djeno sandstone formation.
