Reassess APAC survey and intervention sourcing after new project signals

Our current analysis of the well data suggests that a Pacassa SW injection well is unlikely to be required at this time, a final decision will be made ahead of the completion of the current rig operations,” explained Afentra. Regarding the Impala redevelopment, the Impala-1 well, which had remained shut in since 2017, has been returned to production as part of the light well intervention (LWI) program

The completion of PAC 416 is perceived to constitute a significant milestone in Block 3/05’s redevelopment program, contributing to strengthening production capacity and extending the productive life of its assets. Given Sonangol’s strategy of sustainably increasing operated production, the program foresees the drilling of three wells during 2026, with the purpose of maximizing the exploitation of the existing oil potential in Block 3/05, contributing to the increase in national production

The results from well intervention, together with the reservoir pressure data acquired during testing, have reduced subsurface uncertainty and have been incorporated into the final well planning for Impala-2. The well is expected to target an initial production rate of approximately 4,000 bopd and, if successful, would represent the start of the next phase in the redevelopment of the Impala field

The North Sea Transition Authority claims that the success of this campaign has been supported by a significant improvement in intervention efficiency, with the cost per barrel of oil equivalent added decreasing from £9

Based on the regulator’s data, a total of 398 well interventions were carried out during the year

While the firm previously reprocessed the data in 2014, the new project applies a modern, comprehensive workflow, combining advanced pre-proc

TGS emphasizes that a priority subset of lines will be delivered within seven months, with final products for the full dataset expected in Q3 2027

This campaign was managed directly by Afentra, utilizing a compact remotely operated vehicle (ROV) deployed from a locally contracted vessel. The optimized approach completed the entire scope for a total cost of approximately $60,000, representing a material cost saving compared to conventional contracting market rates of between $500,000 and $1 million for a campaign of this nature

The company emphasizes that no hydrocarbon leakage or seepage was observed, and the campaign was completed with zero safety or environmental incidents
