Chevron North Sea Limited has started production at Alder, a high-pressure, high-temperature (HPHT) gas condensate field in the Central North Sea.

Chevron Upstream Europe managing director Greta Lydecker said: “First gas at Alder represents a significant milestone for Chevron and highlights our commitment to investing and developing resources in the UK.

“The safe and successful completion of this project was underpinned by strong collaboration between Chevron and Alder co-venturer ConocoPhillips.

"Alder supports our goal of helping maximise the economic recovery of the UK, adds significant production to our portfolio, and helps extend the field life of Britannia, an important asset to Chevron in the North Sea.”

The Oil and Gas Authority chief executive Andy Samuel said: “We are very pleased to see the safe flow of first gas from the Alder field. Chevron’s application of innovative subsea technologies and use of the UK’s experienced supply chain is closely aligned to the maximising economic recovery strategy, adding reserves and extending the life of an existing asset.”

Alder is a single subsea well attached to ConocoPhillips-operated Britannia Platform through a 28km pipeline. Chevron holds a 32.38% non-operated working interest in this project.

The facility is designed to hold 110 million cubic feet of natural gas and 14,000 barrels of condensate a day.

The company expects to increase production from this HPHT Alder field in the coming months.

Around 70% of development work of this facility was accomplished by UK-based companies that ushered significant investment to the UK supply chain.

"Alder supports our goal of helping maximise the economic recovery of the UK."

It also assisted to create several hundred jobs in multiple UK locations.

Alder Field was discovered in 1975. The project development was conducted by using innovative subsea technologies that includes a vertical mono-bore subsea tree system, a subsea high-integrity pressure protection system (HIPPS) and a specially designed corrosion monitoring system to measure the real-time condition of the production pipeline.

With its headquarters in Aberdeen, Scotland, Chevron Upstream Europe (CUE) is a strategic business unit of Chevron’s Europe, Eurasia and Middle East (EEME) Operating Company.

In the UK, Chevron North Sea Limited (CNSL) has working interests in ten offshore producing fields, including three operated and seven non-operated fields.

In 2015, at an average these fields produced 40,000 barrels of liquids and 115 million cubic feet of natural gas daily.
