This interactive map has been produced by NSTA to assist companies and members of the public with information that will help understand oil and gas exploration and production activity onshore in Great Britain including those areas already under licence and those areas that are on offer in NSTA’s licensing Rounds.Petroleum Exploration and Development Licences (PEDL’s) grant exclusive rights to search and bore for, and get, petroleum in a specific ordnance survey blocks. PEDL’s cover the various stages of the full development cycle of oil and gas exploration, appraisal; production and eventually decommissioning of the wells, however a PEDL licence grants no automatic permission for drilling or facilities siting and construction. Permission to carry out such activities will be dependent on planning permission from the relevant Local Authority. Developers also have to secure relevant permits from the Environment Agency, and their plans have to pass scrutiny by the Health and Safety Executive.This data is supplied on a best effort basis only, utilising available information as provided by the original operators.
