Ramboll Oil & Gas has just won the Tyra East Rationalisation Project. The Tyra Field is the largest gas field in the Danish sector of the North Sea. The field is operated by Maersk Oil, and production started back in 1984.
Optimising production for future demand
The Tyra East Rationalisation Project is part of a series of optimisation projects – together labeled the Tyra Facilities Optimisation Project – that Maersk Oil is currently carrying out in order to accommodate the late field life with lower reservoir pressure.
The production forecast shows an expected decline in gas and condensate production, which is a feature of all gas fields as they reach a mature stage of production. The opportunity has been taken to accelerate tail end production which helps to increase the overall recovery from the Tyra field by adding additional wellhead compression. Combined with this activity it has also been decided to reduce the gas processing capacity in line with future demand. The Tyra East Rationalisation Project includes optimisations of the Tyra complex and gas infrastructure by reducing capacities to match the future production forecasts and thereby reducing operation cost.
The project will have a duration of approximately 40 weeks extending into 2012.
Cooperation with Maersk Oil
The project will be carried out in cooperation with Maersk Oil, and the main objective is to make a smooth and effective project execution with a ‘single drawing pass life cycle’. Earlier in 2011 Ramboll won the Tyra East Wellhead Compression Project, which is also part of the Tyra Facilities Optimisation. Ramboll project manager, Søren Eg Hansen, adds ‘ We have a long track record of working for Maersk Oil, and we are thrilled to be working alongside their organisation once again.’
