This week sees the release of DECC's 14th onshore licensing round. Potential operators can bid for licences that give them the exclusive right to explore for oil and gas, and indeed shale gas, within their licence block.
Note that having a licence doesn't automatically grant a right to drill or to do hydraulic fracturing. Operators must still get planning permission, and the relevant permits from the EA, DECC, HSE etc before they are allowed to do anything.
Below is a map showing the current state of play onshore in the UK. The map shows existing wells, fields and licence blocks, and the new blocks made available for licensing are shown in purple.
I have also created a google earth .kml file so you can look at this data in more detail. You can download it here.
