The Niger Delta is the twelfth largest province in the world by known oil and gas resources. [4] The Niger Delta Basin produces around 2 million barrels of oil per day. The entire system is predicted to contain 34.5 billion barrels of oil and 94 trillion feet 3 of natural gas. This area is still very heavily explored by oil companies today.
The Niger Delta Basin is an extensional rift basin where rifting occurred from the Late Jurassic to the Late Cretaceous.Cretaceous fracture zones, expressed as trenches and ridges, control the tectonic framework of the delta and separate the margin into individual sub-basins, which form the boundary faults of the Cretaceous Benue-Abakaliki trough.
Sketch map of Benue Trough. The trough has its southern limit at the northern boundary of the Niger Delta, where it dips down and is overlaid with Tertiary and more recent sediments. It extends in a northeasterly direction to the Chad Basin, and is about 150 km wide. The trough is arbitrarily divided into lower, middle and upper regions, and ...

[ 1 ] [ 2 ] It is located within nine coastal southern Nigerian states, which include: all six states from the South South geopolitical zone, one state ( Ondo ) from South West geopolitical zone and two states ( Abia and Imo ...
The oldest rocks in Niger, along the border with Burkina Faso and northern Ghana predate the 2.2 billion year old Proterozoic Birimian rocks common in much of West Africa. . The pre-Birimian crystalline basement rocks include gneiss and migmatite metamorphosed to amphibolite grade in the sequence of metamorphic fac
More than 90% of Sri Lanka's surface lies on Precambrian strata, some of it dating back 2 billion years. [6] The granulite facies rocks of the Highland Series (gneisses, sillimanite-graphite gneisses, quartzite, marbles, and some charnockites) make up most of the island and the amphibolite facies gneisses, granites, and granitic gneisses of the Vijayan Series occur in the eastern and ...
An oil spill in the fishing village of Kegbara-Dere, Rivers State on the Niger Delta. In 2016 Shell paid US$80 million for the spill [1] Petroleum extraction in the Niger Delta has led to many environmental issues. [2] [3] The delta covers 20,000 km 2 (7,700 sq mi) within wetlands, formed primarily by sediment deposition.
The Inner Niger Delta, also known as the Macina or Masina, [2] is the inland river delta of the Niger River. It is an area of fluvial wetlands, lakes and floodplains in the semi-arid Sahel area of central Mali , just south of the Sahara Desert .
