A contract worth about NOK 260 million, including options, covering drilling and well fluids and cementing services for the Kristin development has been awarded to Halliburton.
Placed by Statoil on behalf of the licensees in the Norwegian Sea gas and condensate field, the job runs initially for two years until the autumn of 2004. It can be extended to 2006. This contract represents the exercise of options in Statoil's framework agreement with Halliburton. In addition to drilling and completion fluids and cementing, it covers pumping and personnel services.
"Kristin is a reservoir under high temperature and high pressure (HTHP), and presents technological challenges," explains Bengt Rasmussen, drilling manager for the field. "To carry out operations safely and efficiently, we need to adopt the best available technology, products and personnel."
Halliburton has experience with HTHP reservoirs on the UK continental shelf, and can offer a drilling fluid system developed specially for such operations. Drilling work is due to run from the summer of 2003 to the summer of 2006. Plans call for Kristin to be produced via 12 subsea wells tied back to a floating platform, which will come on stream in the autumn of 2005.
The field is due to deliver about 35 billion cubic meters of gas to 2016. Estimated output of condensate (light oil) and natural gas liquids over the same period will be 220 million barrels and 8.5 million tons respectively.
