There was never any oil in what is today called Seven Heads. The oil potential was always in the Lower Cretaceous sands, what is now usually referred to as the Lower and Basal Wealden. The Barryroe exploration license was created specifically for the sub-4000 foot zone below Seven Heads, and later extended twice to include further acreage. Ramco sold their interests in "Seven Heads oil" to Island Oil and Gas, and Island along with Lansdowne and Providence became the holders of the Barryroe license. The Upper Wealden sands of Seven Heads contain gas, negligible amounts of condensate, and no oil.
The myth that developing Barryroe is just a matter of plugging into existing gas infrastructure is wishful thinking. Sure, it is "merely" a matter of separating oil and gas, but that belies the scale of a monumentally expensive undertaking. It needs an FPSO (floating production, storage and offloading) vessel. Barryroe needs one with heated tanks as the pour point of its oil is somewhere between warm and hot bathwater. Those are billion dollar ships. Back in 2009 when an evaluation was done for Lansdowne by RPS Energy, the lease cost of an FPSO was $80 million per year. That's after you've done all your drilling -- eventually, depending on reservoir connectivity, up to twenty production wells at $30m each. A well head production platform adds another $150m. That's not all up front and, of course, the oil is eventually paying for all this. And rates may well be cheaper in 2020 than in 2009. But somebody still has to stump up a stonking, eye-poppingly huge sum of money to get the process going.
Barryroe also comes with considerable technical risk on top of the political risk and an unfavourable short term economic outlook. We'd all love to see it being developed. But it would be unwise to think there are company's tripping over each other to risk their money on it.
