Mae'r astudiaeth, a gynhahliwyd gan y British Geological Survey, yn rhoi crynodeb cynhwysfawr o'r holl wybodaeth sydd ar gael ar hyn o bryd am  yr adnodd, ar y môr ac ar y tir.  Mae hefyd yn ystyried dulliau o chwilio am yr adnodd, a'i ddatblygu, gan gynnwys nwy siâl, methan gwely glo a nwyeiddio glo tanddaearol, ac adolygiadau o effaith bosib unrhyw ddatblygiad ar yr amgylchedd ac ar iechyd.
The study, undertaken by the British Geological Survey, provides a comprehensive summary of all the currently available information on the resource, both onshore and immediately offshore. It also considers methods of exploration and development of the resource, including shale gas, coal bed methane and underground coal gasification, and reviews the potential impacts of any development on the environment and health.
