West of Shetland stranded pools ‘could yield additional £10bn’ with new tech

“Stranded pools” off Shetland could yield £10 billion in additional revenue, according to a senior subsea engineer.

Lee Thomas, a lead subsea project engineer with WorleyParsons, claimed last night that his new technology could unleash a gas boom in the North Sea, provided big operators “come on board”.

Mr Thomas is currently studying the economic impact of his Pseudo Dry Gas technology to stranded gas fields north of Shetland.

He is proposing a gas gathering corridor stretching 124 miles wide and 1 mile deep while working on in conjunction with the Oil and Gas Technology Centre (OGTC), the Oil and Gas Innovation Centre (OGIC) and Strathclyde University to prove the huge financial potential of his technology.

The technology aims to make long distance subsea tiebacks which have typically not been economically or technically feasible, commercially viable.

Pseudo dry gas technology eliminates the need for topsides and costly compression, along with their associated high C0emissions, by reducing back pressure in the pipeline to create a more energy efficient flow. This allows much greater tie-back distances.

Mr Thomas said: “People don’t realise just how much stranded gas there is around the world and the problem is most people in the industry just haven’t heard of this type of technology.

“The Oil and Gas Authority (OGA) has confirmed the data on the £10bn capital expenditure (capex). We can make this work, it’s going to help a lot of people.”

Mr Thomas also urged big North Sea operators not to be “scared” to put his stranded pools technology to the test.

He added: “It can be too much for some people to grasp sometimes, but we’re the first to really look at this problem.

“But we’re slowly getting the attention of big North Sea operators and we need to start looking at a field trial within the next 18 months.”

Graeme Rogerson, project manager of small pools at OGTC, said: “We’ve got all this gas reserve and it’s stranded. I got really excited about the technology and the potential that it has.

“What this study allows us to do is to present to our members and they will either invest themselves or commit in-kind support.

“This has been backed up with real data from the OGA and it’s starting to make a lot of sense to a few operators.”
