Building anything in the oil and gas industry is an extremely difficult proposition that takes a great deal of commitment and even more expertise. Just the mere thought of the amount of planning it must take to conduct a feasibility study, carry out the front end engineering and design, invite tenders and then actually build a LNG train, petrochemicals complex or offshore facility is enough to make most construction companies decide that they would be better off sticking to apartment complexes and shopping centres.

So it is with this that presents the world’s 10 largest oil and gas contractors. These are the companies that are making sure the hydrocarbons industry has the state-of-the-art facilities required to maintain its position as the world's number one provider of energy.

Like our list of the world’s 10 largest oilfield services companies we have based the list solely on the last financial year’s revenues. However, some companies on the list have higher revenues than others placed above them. This is due to the fact that being conglomerates, they have a number of major interests in other areas of industry that had to be taken into account. Daelim is a good example of this as it has a number of civil infrastructure projects etc that are not oil and gas related. Also Fluor could lay a serious claim, but seeing as it was included in the oilfield services companies list, we decided to feature another company instead. 

The information regarding each company was taken from its respective websites and as much as possible was double checked on other websites including,
the Forbes Global 2000 list, Reuters and a number of other websites.
