Paper presented at the SPE Offshore Europe Conference and Exhibition, September 3–6, 2019
Paper Number: SPE-195725-MS
... Abstract Following the significant reservoir depletion on Elgin / Franklin fields since 2007, drilling infill wells was considered to not only be high cost but also carry a high probability of failure to reach the well objective. The recent campaign on the Elgin field, one of the most heavily...
