In July 2015, Oil and Gas UK said North Sea industry had suffered 5,500 direct job losses from the start of 2014 to June 2015.
In a report published in September, the same organisation estimated that about 65,000 oil and gas related jobs had been lost in the UK over the same period.
Since then, at least 1,000 more have been revealed:
In July, Ensco said it would lay off more than 100 employees, while Bristow Helicopters said 130 staff faced redundancy.
In August, LR Senergy said it had been forced to make 17 cuts earlier in the year.
In September, Hydrasun revealed plans to reduce its headcount by up to 97 employees and Ceona went into administration with the loss of 102 jobs.
In October, helicopter firm CHC confirmed 18 redundancies in the region, Aker Solutions said up to 70 North Sea jobs were under threat, and Lockheed Martin said 27 posts had gone at its Aberdeen base.
In November, Chevron said it was reviewing up to 140 positions across its North Sea operations and Taqa confirmed it had shed 100 staff.
On Monday, Petrofac said 160 positions could be cut, and yesterday BP said would slash its North Sea headcount by 600.
Technip, Dolphin Drilling, Wood Group PSN and Centrica have also announced plans for cuts during this period, but have not provided exact figures for the North Sea.
