Q

MODPU key drivers (6) ?

A
  1. low CAPEX (new build or conversion)
  2. high residual value (easily separable / one single lift Production Module) - back to MODU
  3. able to process a range of fluid types/rates/ pressures, gas-oil ratios and water-cuts.
  4. handle varied metocean, geotechnical and water depth conditions.
  5. relocated quickly
  6. operated with minimal crewing.

Q

What are the key principles of “Honeybee” field development plan ?

A
  1. discovered stranded oilfields (1-8mmbbl)
  2. sub-economic to reduce uncertainty by drilling further appraisal wells
  3. produce until commercial threshold reached then move on to another field

Q

What are the unique Innovations of Honeybee model (6) ?

A
  1. No WHP - Tensioned Well conductors tied back to the MODPU
  2. Wells drilled/completed with light weight hydraulic automated DM located on the PM (lower footprint/cost)
  3. ESPs- lower $ dry trees base case.
  4. MODPU (DM) able to supt wireline ops / ESP workovers / well abandonment
  5. On-board storage (MODPU); 20 - 30,000 bbl in hull (maybe in tanks on seabed) for;
    • ongoing production during short-term FSO disconnect (Cyclone, FSO swap out).
    • continuous ops for ESPs (without need to shut-in wells.
  6. Proven tech only - min 2 years
