Mjøsa spudded in Wintershall’s first Norwegian HPHT campaignWintershall Norge has begun drilling its first High Pressure High Temperature (HPHT) well, in a gas exploration campaign at the Mjøsa prospect in the Norwegian Sea.
The Wintershall operated well, in the southern part of the Haltenbanken area is being drilled by the Transocean Arctic semisub and is slated to reach a total vertical depth (tvd) of 4 436m.
Arild Kjeldstad, exploration team leader, said the campaign, in its length and complexity, represented a milestone for Wintershall Norge.
“This is a very technically challenging and exciting project for us because it is our first HPHT well. At 127 days as an initial plan, it is already a very long campaign and in case of commercial discovery the campaign could last even longer,” he said.
Should Wintershall make a commercial discovery, the well’s success case involves an additional 64 days of coring, logging and drill stem tests (dst), which would take the total drilling campaign to well over half a year.
Wintershall has also invested in a 25 million NOK training project to accompany the drilling campaign that will use simulators to recreate the scheme.
