Half of all spills occur due to pipeline and tanker corrosion and accidents (50%), other causes include sabotage (28%) and oil production operations (21%), with 1% of the spills being accounted for by inadequate or non-functional production equipment.A reason that corrosion accounts for such a high percentage of all spills is that as a result of the small size of the oilfields in the Niger Delta, there is an extensive network of pipelines between the fields, as well as numerous small networks of flowlines--the narrow diameter pipes that carry oil from wellheads to flowstations--allowing many opportunities for leaks..
