Production-induced stresses from time-lapse time shifts: A geomechanics case study from Franklin and Elgin fields

Abstract

Franklin and Elgin fields were discovered in 1986 and 1991, respectively, within the U.K. North Sea Central Graben blocks 22/30 and 29/5. The producing reservoirs are contained in the Jurassic Fulmar shallow-marine and Pentland fluvial formations at depths of 5100–5600 m subsea. The fields presented significant development challenges both in terms of seismic imaging complexity and being in a state of exceptionally high pressure/high temperature (HPHT). Addressing these challenges meant that production could not commence until 2001.
