The Cliff Head facilities are the only offshore infrastructure in the Perth Basin and consist of a jack-up installed unmanned platform, connected by two 14km pipelines to an onshore stabilisation plant at Arrowsmith. Production is processed at the onshore crude stabilisation plant and trucked 350km to the BP refinery in Kwinana.
ROC continues to assess potential development and well optimisation opportunities.
|First production||1 May 2006, less than 14 months after project sanction.|
The northern Perth Basin is a westerly dipping Mesozoic rift margin. The hydrocarbon play at Cliff Head is a series of stacked Permian sandstone reservoirs within fault and dip-closed structures, sealed by the regional Kockatea Shale.
In 2000 ROC farmed into WA-286-P, became Operator, and discovered the Cliff Head Oil Field in 2001. Four appraisal wells were drilled. Final Investment Decision was made in March 2005. A production licence was granted in October 2005. Production facilities were completed in December 2005 and eight development wells were drilled. Production commenced in May 2006.
ROC has a track record of performing ahead of industry averages in safety performance and will continue to pursue the highest standards in HSE. Cliff Head is currently the only commercial oil discovery in the offshore Perth Basin.
