Semi-submersible Drilling Rig Assigned for Kjøttkake Exploration Well Offshore Norway

Oil and gas company Longboat Energy said Tuesday that a semi-submersible drilling rig had been assigned for the drilling of the Lotus (Kjøttkake) exploration well in Norway. Longboat Energy has a 30% stake in the DNO-operated project.

The Lotus prospect will be drilled using the semi-submersible Deepsea Yantai and is expected to be drilled during Q3 2024.  The Deepsea Yantai is a harsh environment semi-submersible drilling rig able of operating at - 22℃.  It can operate at a water depth of up to  500 meters and drill wells down to a depth of 8000 meters. It is owned by CIMC Raffles and managed by Odfjell Drilling.

The partners in the offshore license where the Deepsea Yantai will drill the Kjøttkake well are DNO Norge AS (40%, op) and Aker BP ASA (30%).

Licence PL1182S lies in the prolific Northern North Sea, 4kms southeast of the recent significant Kveikje discovery, where Longboat is a 10% equity partner.

Longboat's Lotus prospect has been named Kjøttkake by the license operator. According to Longboat, the prospect comprises Paleocene injectite sandstones, characterized by excellent reservoir properties, and is supported by seismic amplitudes. 

"Longboat exploited its significant knowledge of injectite reservoirs, which are also the main reservoir in the Kveikje discovery, to secure the Lotus prospect through a firm well commitment in last year's APA 2022 licensing round," Longboat said.

Based on Longboat Energy's estimates, Lotus contains gross mean prospective resources of 27 mmboe with further potential upside estimated at 44 mmboe. The chance of success is 56% with the key risk being hydrocarbon retention.

If successful, Lotus is likely to form part of an area cluster development together with Kveikje and several other recent discoveries in the area, through infrastructure associated with the nearby giant Troll field.

Helge Hammer, Chief Executive of Longboat Energy, commented:"I am pleased that we have secured a rig for drilling Lotus, which could add substantial reserves to our Kveikje development if successful.  

The next well on the program will be Velocette, which is expected to spud late this summer, and which will be followed by Lotus next year."
