Deepwater Indonesia

Deepwater Indonesia (Gendalo/Gehem/Ranggas) – Unocal & Chevron (Oil/Gas, Indonesia)

Chevron (ex-Unocal) has several deepwater assets, located in the East Kalimantan Basin, offshore Indonesia. Aside from being highly delineated reservoirs, the fluid properties of the fields vary from benign gas to paraffinic oils.

Wood Group Kenny's Process Solutions group has been involved in various facets of the Indonesia projects since their inceptions. Our consultants performed an extensive parametric study on pre-FEED and gas export for the Gendalo field to screen possible development options for a long-distance gas/condensate pipeline. Our team considered multiple variables in an attempt to define potential operating regimes for both a subsea production line and a gas export line.

Subsequent phases of work included:

  • Operability study/operating envelopes
  • Production chemistry/fluid testing oversight
  • DST thermal modelling and validation
