Cecilie

Cecilie is a fixed steel unmanned wellhead platform in the Danish North Sea, developed to exploit the Cecilie field's oil. Commissioned in 2003, it lacks independent processing capability and routes production via pipeline to the Siri SCA platform for processing and export. Water depth at the site is approximately 60-m.

Field

The Cecilie field is a small sandstone oil reservoir in the Danish southern North Sea, southwest of Siri. The trap is structural and stratigraphic in Paleocene sandstone. Development uses a single wellhead platform tied back to Siri for processing. Reserves are modest relative to neighboring fields.

Facilities

Cecilie consists of a fixed steel wellhead platform with several production wells accessing the sandstone reservoir. Its function is to collect well fluids and export them via subsea pipeline to the Siri SCA installation, where separation and basic processing occur. There is no significant processing plant on Cecilie; utilities are limited to well control, minimal power generation, and communications. The export infrastructure consists of subsea pipelines linking to Siri for combined handling with Siri, Nini and Stine fluids. Supporting systems include basic deck utilities for instrumentation, power distribution, fire and gas detection, and remote telemetry.
