Oil & Gas UK Activity Survey 2016

Appraisal Appraisal activity also continued to decline with 13 wells (including ten geological sidetracks) drilled in 2015. Activity has fallen sharply over the last decade from an average of 51 wells per year from 2006 to 2010 to an average of only 24 wells per year from the period 2011 to 2015. This fall is in part driven by the need to keep pre-development costs down for smaller prospects by cutting back on the number of appraisal wells drilled. The lack of exploration success in recent years means there are also fewer new opportunities to appraise, while the low oil price means companies are less likely to appraise more marginal discoveries that may turn out to be sub-economic in the current climate.
