More than 160 new oil and gas production licences have been offered to companies seeking to explore the North Sea, the Government has said.
The licences cover 330 "blocks" of the sea and if completed would represent a sharp increase in the level of exploration. A further 61 blocks are still being assessed for the environmental impact of oil and gas exploration.
The 167 offers follow news in May of record breaking levels of interest in exploring new blocks of the North Sea, when 224 applications were made for 418 blocks of the UK continental shelf.
Energy Minister John Hayes said: "Fortune has favoured the UK. Oil and gas from our waters provides around half the energy we need to heat our homes, fuel our cars and power our industry.
"It is the single largest industrial UK investor, supporting 440,000 jobs, and benefits the UK's trade balance to the tune of £40 billion.
