UK independent Zennor Petroleum has drilled a successful appraisal well on the Finlaggan gas condensate accumulation in the UK North Sea.
Finlaggan is in license P2013, in Block 21/5c, awarded in the 27th licensing round to Zennor. The Finlaggan discovery was made by ConocoPhillips in 2005, with estimated gross mean gas condensate reserves of 27 MMboe in the lower cretaceous.
The well 21/5c-7 and side-track 21/5c-7Z was drilled using Transocean's Sedco 704 drilling rig.
Well 21/5c-7Z was drill stem tested at a stable rate of 9785 b/d (40 MMscf/d of gas and 3120 b/d of condensate). The flow rate was constrained by the capacity of the surface testing equipment.
The data from the wells will now be integrated into a detailed reservoir model to define the estimated reserves, which Zennor expects to demonstrate the commercial potential of Finlaggan consistent with the range of pre-drill estimates.
In parallel with the drilling, Zennor’s engineering teams have been making good progress in discussions with the operators of potential offtake routes for the Finlaggan hydrocarbons.
Finlaggan is close to the Enochdhu and Callanish fields, both of which are part of the Greater Britannia area, operated by ConocoPhillips.
Engineering studies are underway with several companies, with the intention of being able to deliver first production from Finlaggan no later than 2019.
Zennor Petroleum’s wholly owned subsidiary Zennor Pathway (operator) holds a 100% interest in License P2013.
Zennor was founded in 2006 (then named MPX) and the company’s majority shareholder is The Kerogen Energy Fund II, a private equity fund managed by Kerogen Capital.
Zennor’s heritage goes back to the mid-1990s and the missed pay strategy of ARCO International, where many of the Zennor team worked.
