Searching for oil is like looking for a needle in a haystack. Of course, technology and geology play a big role in telling the oilmen where to drill for oil. A viable oilfield is a source that may be in the middle of an ocean or in the heart of a desert, which contains petroleum rich deposits. The only way to remove this oil is to drill for it. Oilfields are usually found in the most difficult and isolated locations. Oilfield hauling service companies have trained workers who have to extract the oil have to work in the most extreme of climates.
Besides housing all the workers, supplying 3 square meals a day or night, taking care of construction, machinery, transportation, and healthcare, these providers also have to make sure there is no breakdown of the oil supply. Oil that is collected needs to be stored and sent to the refinery at regular intervals. An oilfield in Canada normally operates round-the-clock all year-round.
Most of the big oil companies are struggling with the regularizing the crude supply due to the extreme climate in which the newly discovered oilfields are located. The oilfield constructions and heavy equipment required also breakdown very often, and need to be repaired and serviced regularly.
