Block 29/7b – Curlew A: Cromarty and Odin oil discovery

Specifications

  • ~20km2 closure

  • 92-95 metres water depth

  • ~150m column height

  • 10m net oil pay in Odin-Cromarty Tertiary sands

  • 30% porosity sands and likely high permeability

  • Thin sands below seismic resolution

  • Similar to salt dome fields Orion and Stella

  • P90 volumes too small to develop normally but with Pivotree we are able to develop with the P90 volumes with a single well development.
