New shallow water solution helps development of future gas fields

Fourty years after its discovery Total E&P Nederland developed the gas reserves of the K4-Z field (located in the North Sea), using a series of innovations.

New ideas will benefit future projects 
Because K4-Z is located in very shallow waters (36 meters) we needed to development of subsea production system for this. It’s a prime example of an innovation that will be beneficial to the entire group. It was also the first time for the group that we laid a pipeline and umbilical in one trench and used a new pipeline dry insulation system.
 
12 years of continuous energy supply
K4-Z facilities have been sized to accommodate two subsea wells, but capacity for a potential third well tie-in is available. First production from the two K4-Z wells confirmed expected reserves. The proven reservoir potential stands at 11,500 barrel of oil equivalent per day. This will increase our production by approximately 10% and promises around 12 years of continuous production.
 
Developing long discovered fields
The K4-Z field was discovered more than 40 years ago. When discovered, development costs proved to be higher than revenues. Only when the Dutch government instated its marginal fields policy and an accelerated depreciation measure in 2010, we were able to develop the field in an economically viable way.
