Conjugate Margins

The overall objective is to Improving predictability of reservoir source rock and seal at different stages of conjugate margin development. This requires the development of tectono-sequence stratigraphic models to predict the spatial and temporal development and distribution of key play elements in conjugate margins, with particular emphasis on sediment supply routeing and resultant reservoir quality. Improving predictability of reservoir at different stages of transform margin development needs to be investigated. Specific objectives include:

  1. Refinement of sequence stratigraphic models from rift settings to incorporate the dynamics of fault transfer zones, strike-slip tectonics (including periods of inversion) and complex, evolving sediment routeing scenarios to understand where and when sediment is fed into the conjugate, and where it goes.
  2. Understanding subsidence patterns in space and time in hyper-extended margins and how conjugate asymmetry affects play element distribution
  3. Developing mass balance approaches to sediment delivery, bypass and deposition
  4. Understanding how shifting provenance areas, as the conjugate margin develops, affects sediment calibre and compositional changes, hence potential reservoir quality. For example, low volumes of clean sand supplied to the deep water via longshore transport during highstands may be more important reservoir than much larger volumes of lowstand volcanic-rich submarine fans.
