Intriguing video. Towards the end, and prompted by a question, Graham Swindells expands on the relationship with Shell. Let’s also remember that Shell operates as a 50/50 joint venture with Exxon - so a powerful combination. He portrays the P2252 Licence prospects as a new play opener with considerable upside which will attract interest in the 32nd Licencing Round.
In fact the Zechstein play was the original target in 1952 for one of the first wells drilled in the northern part of the Netherlands when exploring for oil. But it found traces of gas a little deeper in Lower Permian sands, The next well, drilled in 1955, also failed to find oil in the Zechstein, but eventually in 1959 the third well confirmed the discovery of the Groningen - Europe’s biggest gas field.
Exxon- with Shell - is Germany’s largest natural gas producer, with production from fields accounting for approximately 70 percent of all natural gas produced in the country and are familiar with the Zechstein play.
Back in UK, the Zechstein play is virtually untouched. The Maxwell gasfield was discovered in Permian Zechstein carbonates with 41/24a-1 in 1969. Two follow-up appraisal wells 41/24a-2 In 1981 and 41/24-3 in 1992 were drilled into the fractured Zechstein carbonate reservoir.
The maximum flow rate on test of 34 mmscfd from a vertical well and over 100 mmscfd from a horizontal well drilled by Conoco - and all this about 12km east of Scarborough.
It’s a drilling challenge with lost circulation zones, but Shell has pioneered successful drilling in the Drenthe area in Netherlands where they have discovered several TCF of gas in the Zechstein play.
In summary, if I were CNRL, I’d try to downplay the scale of the Zechstein play because they’ll have a competitive edge in the 32nd Round with an early view of how modern 3D can illuminate this new prospective trend. The ‘post-3D’ CoS may be greater than 20% - that’s the whole point.
