North Sea Tybalt well to examine tieback potential

Offshore staff

WOKING, UK – The semisub Borgsten Dolphin has spud an appraisal well on the Tybalt discovery in blocks 211/8c and 13c in the UK northern North Sea.

Operator Valiant Petroleum says the aim of the 35 to 40-day program, which includes a contingent test, is to prove up commercially exploitable volumes via nearby infrastructure which includes the Magnus fields and the Dons Area complex.

Tybalt is an Upper Jurassic find with gross resources estimated at 7 MMbbl. Valiant’s partner in the license is Agora Oil and Gas (UK).

On completion of operations, the rig could transfer to block 3/17 to drill the Tryfan prospect (Valiant 33.33%) operated by Apache North Sea, prior to undertaking development work on the Causeway field where Valiant is operator.

Tryfan is an Eocene channelized sand play which exhibits a strong seismic amplitude response. Valiant estimates reserves here at 24 MMboe.
