This increases to 37 production licences with the inclusion of the assets from the acquisition of the Greater Kittiwake Area which completed in Q1 2014 and the Don North East area licence which was offered 'out of round' to EnQuest in Q1 2014; these licences cover 47 blocks or part blocks in the UKCS, 30 of the licences are operated by EnQuest. EnQuest believes that the UKCS represents a significant hydrocarbon basin in a low risk region, which continues to benefit from an extensive installed infrastructure base and skilled labour.  EnQuest believes that its assets offer material organic growth opportunities, driven by exploitation of current infrastructure on the UKCS and the development of low risk near field opportunities. EnQuest has begun replicating its existing model in the UKCS by targeting previously underdeveloped assets in a small number of other maturing regions; complementing our operations and utilising our deep skills in the UK North Sea. In this context, EnQuest also has interests in two blocks offshore Sabah, in Malaysia and a small field risk service contract, offshore Sarawak in Malaysia.
