Description Norwegian

Development

Balder is an oil field in the middle part of the North Sea, at a water depth of 125 metres. The field has been developed with subsea wells tied back to the accommodation, production and storage vessel, «Balder FPSO», where oil and gas are processed. The Ringhorne discovery, included in the Balder field, is developed with a combined accommodation, drilling and wellhead facility, tied back to the «Balder FPSO». The PDO for Ringhorne was approved on 11.05.2000 and production started on 21.05.2001. An amended PDO for Ringhorne was approved on 14.02.2003.

Reservoir

The field contains several separate oil deposits in Eocene and Paleocene sandstones. The main reservoirs are in the Rogaland Group and belong to the Heimdal, Hermod and Ty Formations at a depth of about 1 700 metres.

Recovery strategy

Balder and Ringhorne produce primarily by natural aquifer drive, but some water injection for pressure support is utilised,especially at Ringhorne. Gas is also injected if the gas export system is down.

Transport

Oil and gas from the Jurassic reservoir at Ringhorne are transported to Jotun for processing, while oil from the Rogaland Group is routed to Balder. Gas from «Balder FPSO» is transported to «Jotun FPSO», and then exported via Statpipe. In periods with reduced gas export, excess gas may be injected in Balder.

Status

The field is in the decline phase, but it is assumed that it will continue producing until 2025. Studies have been started to evaluate possible means to improve recovery. A 4D seismic survey completed in 2009 has been analysed to evaluate new well locations. Five new production wells are being planned at both Ringhorne and Balder from 2010-2012. These can start production from 2011-2014.
