The Cliff Head Field, offshore Western Australia, faced significant
development challenges because of its location and reservoir fluid properties.
The influence of these challenges is apparent in the development solution
adopted from sandface to market. The modest reserve size required the
application of a number of firsts, including coiled tubing (CT), deployed
electric submersible pumps (ESPs) combined with intelligent completion
technology, a novel water "spike" approach to waxy crude
transportation, a distributed chemical injection system, a remote-controlled,
normally unmanned production platform, produced water re-injection, and
"hydrofrac" water-injection capacity.
This paper describes the flow assurance and production chemistry challenges
facing the development, the resulting development solution, and the production
history to date.
The Cliff Head field is located in Commonwealth hydrocarbon exploration
permit WA-286-P in the offshore Northern Perth Basin, Western Australia. Cliff
Head is the first offshore development within the region. The field was
discovered in December 2001 when Brent crude prices were at USD $20 per barrel.
The field contains 15.7 million barrels of estimated ultimate oil recovery.
