Conversion factors:

The approach used to calculate barrels of oil equivalent is based upon the following (approximate) conversion factors:

1 tonne of crude oil = 7.5 barrels of oil equivalent
1 cubic metre of gas = 35.31 cubic feet of gas
1 cubic feet of gas = 1/5800 barrels of oil equivalent

Figures for resources not yet discovered are naturally subject to a higher degree of uncertainty than those for discovered resources. The discussion of undiscovered resources on the website notes that these estimates provide only a broad indication of the ultimate potential remaining. Summing the overall estimates of the three categories of resources (Reserves, Potential Additional Resources, and Undiscovered Resources) does not imply any particular levels of probability. However, with the increasing maturity of the UKCS, there is understandable interest in the question of how much further production is likely. To facilitate more meaningful answers to such questions, the figures for undiscovered resources now include two mid-range estimates of undiscovered resources - the lower of 6.0 [6.4] billion barrels of oil equivalent (boe) corresponding to a reasonable estimate of what might be found based on current knowledge, the higher of 8.8 [9.6] billion boe corresponding to a reasonable estimate of what might be found with better understanding of the basins or better technology.

Taking account of this range of possibilities for undiscovered reserves, our current best estimate of remaining recoverable hydrocarbon resources from the UKCS is of a figure approaching 20 billion boe. But it is of course entirely possible that the development of better understanding and technological change will in the event enable a higher figure to be reached.
