"Considerable uncertainties" surrounded the U.S. economic outlook, particularly the drag on exports from slowing global growth, low investment caused by the decline in oil prices and a “disappointing” recent drop in U.S. job growth.

Britain's North Sea oil and gas sector has shed more than 5,000 jobs since late last year, the country's new Oil and Gas Authority said on Monday, putting an official figure on job losses resulting from a year-long decline in oil prices.

Last month, the oil giant revealed it would cut about 950 jobs in Houston, plus 500 jobs at its San Ramon headquarters, 50 international jobs and 600 contractor jobs.

Worldwide, job cuts from the oil bust reached a staggering 150,000 at the end of May, according to energy recruiting firm Swift Worldwide Resources. However, some analysts believe the worst is over, and by the end of the year, the US could see a stout recovery. Analysts tend to agree that a slowdown in non-OPEC production, led by U.S. shale producers, and unrest in the Middle East and North Africa, particularly Iraq, would support prices this year.

According to a recent report from Swift Worldwide Resources, over 150,000 jobs in the global oil and gas industry have been cut since oil prices began to tumble last summer.

Pro-development policies could increase cumulative local, state, and federal government revenue by over $1 trillion and lower average annual household energy expenses by $360 by 2035, according to the study. A path of regulatory constraints would lead to a cumulative decrease of $500 billion in government revenue from 2016 to 2035 and an increase of $242 in average annual household energy costs.

Declines in oil and natural gas extraction and support employment tend to lag declines in crude oil prices. As prices of North Sea Brent crude oil fell from their June 2014 level of $112 per barrel, firms reduced the number of new wells drilled and the associated workforce. The count of drilling rigs in the United States, as measured by Baker Hughes, totaled 857 for the week ending June 19, 54% below the same point a year ago and the lowest level in nearly six years.

Large cuts in the energy industry have made news for the first two quarters of 2015. Halliburton cut 9,000 jobs in six months and reported a loss of $643 million in Q1 of 2015. Schlumberger reported even deeper cuts that tallied around 11,000 in efforts to reduce personnel employment 15 percent when compared to the third quarter of 2014.

Oil services company Weatherford International Plc increased the total number of employees it is looking to lay off in 2015 to 10,000 as it copes with the fall in oil prices.

Halliburton has cut 9,000 jobs in about six months and is considering additional cost-cutting moves as falling oil prices reduce demand for its drilling help.
