Sigh. I think I’m going to need to start sending out Freedom of Information requests… Several cups of tea later…

Re: Policy and Strategy for North Sea Natural Gas Fields Depletion
Dear Madam / Sir,
I researching the history of the development of the gas industry in the United Kingdom, and some of the parallel evolution of the industry in the United States of America and mainland Europe.
In looking at the period of the mid- to late- 1960s, and the British decision to transition from manufactured gas to Natural Gas supplies, I have been able to answer some of my questions, but not all of them, so far.
From a variety of sources, I have been able to determine that there were contingency plans to provide substitutes for Natural Gas, either to solve technical problems in the grid conversion away from town gas, or to compensate should North Sea Natural Gas production growth be sluggish, or demand growth higher than anticipated.
Technologies included the enriching of “lean” hydrogen-rich synthesis gas (reformed from a range of light hydrocarbons, by-products of the petroleum refining industry); Synthetic Natural Gas (SNG) and methane-“rich” gas making processes; and simple mixtures of light hydrocarbons with air.
In the National Archives Cmd/Cmnd/Command document 3438 “Fuel Policy. Presented to Parliament by the Minister of Power Nov 1967”, I found discussion on how North Sea gas fields could best be exploited, and about expected depletion rates, and that this could promote further exploration and discovery.
In a range of books and papers of the time, I have found some discussion about options to increase imports of Natural Gas, either by the shipping of Liquified Natural Gas (LNG) or by pipeline from The Netherlands.
Current British policy in respect of Natural Gas supplies appears to rest on “pipeline diplomacy”, ensuring imports through continued co-operation with partner supplier countries and international organisations.
I remain unclear about what official technological or structural strategy may exist to bridge the gap between depleting North Sea Natural Gas supplies and continued strong demand, in the event of failure of this policy.
It is clear from my research into early gas field development that depletion is inevitable, and that although some production can be restored with various techniques, that eventually wells become uneconomic, no matter what the size of the original gas field.
To my mind, it seems unthinkable that the depletion of the North Sea gas fields was unanticipated, and yet I have yet to find comprehensive policy statements that cover this eventuality and answer its needs.
Under the Freedom of Information Act (2000), I am requesting information to answer the following questions :-
1. At the time of European exploration for Natural Gas in the period 1948 to 1965, and the British conversion from manufactured gas to Natural Gas, in the period 1966 to 1977, what was HM Government’s policy to compensate for the eventual depletion of the North Sea gas fields ?
2. What negotiations and agreements were made between HM Government and the nationalised gas industry between 1948 and 1986; and between HM Government and the privatised gas industry between 1986 and today regarding the projections of decline in gas production from the UK Continental Shelf, and any compensating strategy, such as the development of unconventional gas resources, such as shale gas ?
3. Is there any policy or strategy to restore the SNG (Synthetic Natural Gas) production capacity of the UK in the event of a longstanding crisis emerging, for example from a sharp rise in imported Natural Gas costs or geopolitical upheaval ?
4. Has HM Government any plan to acquire the Intellectual Property rights to SNG production technology, whether from British Gas/Centrica or any other private enterprise, especially for the slagging version of the Lurgi gasifier technology ?
5. Has HM Government any stated policy intention to launch new research and development into, or pilot demonstrations of, SNG ?
6. Does HM Government have any clearly-defined policy on the production and use of manufactured gas of any type ? If so, please can I know references for the documents ?
7. Does HM Government anticipate that manufactured gas production could need to increase in order to support the production of synthetic liquid vehicle fuels; and if so, which technologies are to be considered ?
Thank you for your attention to my request for information.
