Statoil drilling first production well at Gina Krog field

Statoil ASA has started drilling the first production well at Gina Krog field, 30 km northwest of Sleipner in the North Sea (OGJ Online, Oct. 28, 2014).

Gina Krog has 20 well slots, and Statoil said Maersk Drilling’s Maersk Integrator jack up rig will drill wells until 2019.

The current plan is to drill 14 wells. Ten will be production wells and four will be combined gas injection and production wells. During the first years of production, gas will be injected as pressure support to extract more oil.

Statoil will drill the top sections of six wells after ten 30-in. conductors are installed. Two or three wells will be drilled into the reservoir before the topsides arrive from South Korea.

Statoil said installation of the steel jacket and predrilling module was completed in June.

Gina Krog, previously known as Dagny, was originally a minor gas discovery that had been considered for development on a number of occasions since its discovery in 1974. A plan for development and operation of the field was submitted in 2012. Most recently, Statoil let a contract for design and installation of topsides for the field’s platform (OGJ Online, Feb. 20, 2013).
